✨Auckland in June: Five Wellness Habits for Winter✨

17/6/2026

 
Picture
Auckland winters are not dramatic. There is no snow, no polar wind, no hard freeze. What there is, for many people, is a quieter erosion: mornings that take longer to get going, energy that does not quite return after a busy week, a sense of flatness that is easy to dismiss as just how winter feels.
It does not have to be. Below are five habits that Auckland clinicians and wellness practitioners consistently come back to during the winter months — not because they are revolutionary, but because they work, they are low-cost, and most people are not doing all of them consistently.

1. Get outside between 11am and 2pm, even briefly
This is the single most underused winter wellness lever in Auckland. During June and July, UVB radiation — the type that triggers vitamin D synthesis in the skin — is at its lowest intensity of the year. The window in which meaningful synthesis can occur is narrow: roughly late morning to early afternoon.

A 15 to 20-minute walk during this window, with arms and face exposed (no sunscreen for this brief period), contributes meaningfully to vitamin D production. It also exposes you to natural light, which helps anchor your circadian rhythm — the internal clock that governs sleep, energy, and mood. This is not a prescription for sun damage; it is an argument for a short walk at lunchtime rather than eating at your desk.

2. Prioritise protein at breakfast
Blood sugar stability has an outsized effect on energy and mood across the day. A breakfast dominated by processed carbohydrates — white toast, sugary cereals, pastries — typically produces a rapid glucose rise followed by a slump that lands around mid-morning and is often interpreted as needing more coffee.

A protein-centred breakfast (eggs, Greek yoghurt, smoked salmon, legumes, nuts) slows glucose release and tends to sustain energy more evenly across the morning. In winter, when energy reserves already feel lower, this makes a material difference for many people. It is not a complicated change, but it requires intention because carbohydrate-heavy breakfasts are the path of least resistance in most Auckland kitchens.

3. Set a consistent wake time — not just a consistent sleep time
Sleep advice usually focuses on when you go to bed. The more powerful lever, according to sleep researchers, is when you wake up. A consistent wake time — including weekends — anchors your circadian rhythm more effectively than any other single sleep intervention. It sets the timing of cortisol, melatonin, and body temperature cycles that determine how easily you fall asleep and how restorative that sleep is.

In practice, this means resisting the temptation to sleep in significantly on weekends. A one-hour variation is manageable. A three-hour difference between weekday and weekend wake times — common in Auckland professionals — is enough to cause what sleep researchers call social jet lag, which accumulates across the winter weeks.

4. Reduce caffeine after 1pm
Caffeine has a half-life of roughly five to seven hours in most adults — meaning that a coffee at 3pm still has a meaningful amount of caffeine active in your system at 8pm. In winter, when many people are already sleeping more lightly due to lower vitamin D, reduced movement and elevated stress, evening caffeine compounds the problem.

The 1pm cut-off is a practical guideline rather than a hard rule — individual caffeine metabolism varies, and some people process it faster. But if your sleep has been lighter than usual this winter, the afternoon coffee habit is worth examining before reaching for supplements or other interventions.

5. Move daily, even when motivation is low
Exercise motivation tends to drop in winter. The daylight is shorter, the mornings are darker, and the couch is more appealing. This is not a character flaw — it is a physiological response to reduced light exposure and lower temperatures that is well-documented across populations.

The counterintuitive finding from the research is that even low-intensity daily movement — a 20-minute walk, 15 minutes of stretching, a gentle cycle — has a greater cumulative effect on mood and energy than a single intense weekly session. Consistency trumps intensity during winter. The goal is to maintain the habit, even in a reduced form, rather than swinging between inactivity and compensatory effort.

At Nandish, these five habits are the foundation we come back to before reaching for any clinical intervention. They are not glamorous, but they are where most winter wellness gains actually live. If you are doing all five consistently and still struggling — with energy, mood, sleep, or a sense that something is off — that is a conversation worth having with a clinician.

✨Inside an IV Infusion at Nandish: What to Expect✨

10/6/2026

 
Picture
One of the most consistent things people tell us when they book their first IV at Nandish is that they had a lot of questions they were not sure how to ask. What actually happens? Will it hurt? What do you do for an hour? What if something feels off?

This post is written to answer all of those questions plainly. It is a step-by-step account of what the experience looks like at Nandish Health — from the moment you book through to your follow-up conversation. If you are considering an IV infusion and want to know exactly what you are walking into, this is for you.

Before your visit: the consultation
No infusion at Nandish happens without a prior consultation. This is not a box-ticking exercise — it is the part that makes everything else clinically appropriate.

The consultation might be your first appointment at Nandish, or it might be part of an ongoing relationship with the clinic. Either way, it is a genuine conversation. We ask about your health history, your current symptoms and concerns, your medications and supplements, any known allergies, and your lifestyle. We ask what has brought you to us, and what outcome you are hoping for — knowing that what you hope for is not always the same as what will help most.

If you have recent pathology results — a blood panel from your GP, ferritin levels, a B12 result — please bring them or share them beforehand. They are useful context that helps us understand your picture rather than starting from scratch.

Based on the consultation, the clinician will discuss whether IV therapy is appropriate for you, what kind of infusion makes sense, and what the alternatives or complements might be. If an IV is not the right fit for what you have described, we will tell you honestly — and talk through what might be more useful.

What we screen for
Before any infusion is administered, we confirm that you do not have contraindications that would make IV therapy inadvisable. These include:
  • Certain kidney conditions that affect fluid and electrolyte management
  • Heart failure or significant cardiovascular conditions where fluid load is a concern
  • Known allergies to any component of the proposed infusion
  • Active infection or fever in some contexts
  • Pregnancy — which requires specific clinical consideration
This screening exists because IV therapy is a clinical procedure, not a consumer product. It should feel reassuring rather than inconvenient. If you are in good general health and your GP has not flagged any major concerns, you are unlikely to encounter a contraindication. But the check matters.

Arriving at the clinic

The Nandish clinic is designed to feel calm. We are not a medical waiting room with strip lighting and plastic chairs, and we are not a nightclub-aesthetic drip bar. The environment is quiet, warm, and unhurried — which is the right setting for a procedure that involves sitting still for a meaningful period of time.

When you arrive, a member of the team will welcome you, confirm your details, and settle you into the treatment area. If you have questions you forgot to ask before arriving, now is a good time to ask them.

A few practical things: wear comfortable clothing with easy access to the inner arm (a loose-sleeved top is ideal). Eat something beforehand — arriving fasted is not necessary for most infusions and can leave some people feeling lightheaded. Bring something to do if you like — reading, listening to a podcast, or simply resting are all fine. You do not need to be on your phone.

The clinical assessment on the day
Before the cannula is placed, the clinician will do a brief assessment: confirm your vital signs (blood pressure and heart rate), ask how you are feeling today compared to when you last spoke, and review any changes since the consultation. This is a quick step but an important one — circumstances can change, and we want to know your status on the day.

Preparing the infusion: how your protocol is chosen
The infusion is prepared according to your protocol — the specific combination of fluids, vitamins, and minerals that the clinician has determined is appropriate for you. At Nandish, these are not off-the-shelf packages that every patient receives. They are individualised formulations mixed under clean conditions.

Your clinician will confirm with you what is in your infusion before it is started. If you want to understand what each component is and why it is included, ask — we are happy to explain.

The infusion: the cannula, the sensation, the time
A small cannula — a thin flexible tube — is placed in a vein, typically in the inner arm or the back of the hand. The placement involves a brief, sharp sensation similar to a blood test. Once the cannula is in position, it is secured with a small adhesive dressing, and the infusion line is connected.

Most people describe the experience of the infusion itself as unremarkable. You may notice a slight coolness as the fluid enters. With certain constituents — magnesium in particular — some people notice a mild warmth or a gentle flushing sensation; this is normal and typically resolves quickly. If anything feels uncomfortable or unusual, you tell us, and we adjust.

The duration depends on what is being administered:
  • Hydration infusions — approximately 20–45 minutes
  • Vitamin and mineral infusions (including the Myers cocktail) — typically 30–60 minutes
  • Iron infusions — varies significantly by preparation; some are 15–30 minutes, others several hours
  • NAD+ infusions — these are administered slowly and may take 2 hours or more
You are monitored throughout. A member of the team checks in regularly. You are not left alone in a room with a drip bag and a timer.

During the infusion: what to do
Whatever helps you relax. Many people read. Some listen to music or a podcast with earphones. Some take a nap — the treatment area is quiet enough for it. Some like to talk. You do not need to do anything particular; the infusion works the same regardless.

The one practical note: try not to bend the arm with the cannula significantly, as this can affect flow. If the cannula arm is your dominant hand, it can take a little adjustment.

After the infusion: what you might notice
Once the infusion is complete, the cannula is removed and a small dressing is applied. Most people feel fine to drive and return to their usual activities immediately.

Some people report feeling a sense of calm or lightness after an infusion — particularly those containing magnesium. Some feel very little change on the day, with any response being more gradual over the following days. Individual responses vary, and we are careful not to promise a particular subjective experience.

It is worth staying well hydrated for the rest of the day. Light physical activity is fine; if you have had an iron infusion specifically, the clinician will give you tailored aftercare guidance.

If you notice any unusual symptoms after leaving — significant redness, swelling or bruising at the cannula site, or anything that concerns you — contact us. We would rather hear from you unnecessarily than have you wondering.

When we follow up
For most infusions, we follow up within a few days to understand how you are feeling. For iron infusions and other clinically significant protocols, follow-up may include retesting at an appropriate interval to assess response. This follow-up is part of the service — it is how we know whether what we have done is working and whether any adjustments are warranted.

Frequently asked questions

Will it hurt?
The cannula placement involves a brief, sharp sensation — similar to having a blood test. Once it is in position, most people do not notice it.

Can I eat before my infusion?
Yes — we recommend it. Arriving having had something to eat is generally more comfortable than arriving fasted.

Can I drive afterwards?
For most infusions, yes. If you are having a NAD+ infusion for the first time, we suggest allowing some time before driving as the experience can be more intense for some people. We will advise you specifically.

What if I feel unwell during the infusion?
Tell us immediately. The infusion can be slowed or stopped at any point. We are equipped to respond to adverse reactions, and adverse events during a well-conducted IV infusion in a clinic setting are rare.

Do I need to book in advance?
Yes. We do not accept walk-ins for IV therapy — each infusion requires a prior consultation and preparation time. Booking ahead ensures we have the right time and protocol ready for you.

✨Magnesium for Sleep: An Evidence-Based Look✨

10/6/2026

 
Picture
Magnesium has become one of the most talked-about supplements in the wellness space — particularly in relation to sleep. The conversation is often oversimplified in both directions: either magnesium is presented as the answer to every sleep problem, or it is dismissed as a trendy supplement without meaningful effect. The evidence sits somewhere more nuanced than either position.

This post looks at what magnesium actually does in the body, what the research on sleep says, who might benefit from paying attention to their magnesium status, and how to approach this practically.

What magnesium does in the body

Magnesium is one of the most abundant minerals in the human body — and one of the most active. It is involved in over 300 enzymatic reactions, including energy production, protein synthesis, blood glucose regulation, and blood pressure management. It plays a direct role in muscle and nerve function: magnesium ions are involved in the transmission of nerve signals and in the relaxation of muscle fibers after contraction.

In the context of the nervous system, magnesium regulates the activity of N-methyl-D-aspartate (NMDA) receptors — receptors involved in neural excitation. When magnesium levels are adequate, there is a degree of natural buffering against neural over activation. This is thought to be one of the mechanisms through which magnesium may be associated with calmer nervous system activity and better sleep.

What does the research on magnesium and sleep show?
The honest answer is: there is a meaningful signal, but it is not definitive, and effects are not uniform across people.

Several studies have found associations between low magnesium status and poor sleep quality, including shorter sleep duration and more frequent waking. A randomized controlled trial published in the Journal of Research in Medical Sciences found that magnesium supplementation in older adults with insomnia led to improvements in sleep onset, duration, and early morning waking compared to placebo.

Other studies have examined magnesium's effects on stress and cortisol regulation — the stress hormone that, when elevated in the evening, can delay sleep onset. There is evidence that magnesium intake is associated with lower inflammatory markers and cortisol levels, though the directionality (does low magnesium cause elevated cortisol, or does chronic stress deplete magnesium?) is not fully established.

What the research does not support is the idea that magnesium supplementation will reliably fix a sleep problem regardless of its cause. Sleep is affected by many factors — circadian rhythm disruption, screen exposure, caffeine timing, sleep environment, underlying anxiety, sleep apnea, and pain among them. Magnesium may be one piece of a broader picture, not the whole solution.

Who might have inadequate magnesium status?

Population-level surveys suggest that many people in Western countries have magnesium intakes below recommended amounts. Contributing factors include:
  • Low dietary intake of magnesium-rich foods — leafy greens, legumes, nuts, seeds, whole grains, and dark chocolate are among the richest sources
  • Chronic stress — stress hormones increase magnesium excretion via the kidneys
  • High caffeine or alcohol intake — both have diuretic effects that can increase magnesium loss
  • Digestive conditions that impair absorption — Crohn's disease, coeliac disease, and similar
  • Certain medications including PPIs, diuretics, and some antibiotics
  • Older age — absorption tends to decrease and excretion increases with age
It is worth noting that standard blood tests for magnesium (serum magnesium) can be within range even when intracellular magnesium is depleted — because the body draws on stores to keep blood levels stable. This means a "normal" serum result does not always rule out suboptimal magnesium status. A functional or red blood cell magnesium test can provide a more sensitive picture.

Dietary approaches to magnesium
For most people, the first-line approach to improving magnesium status is dietary. Foods with high magnesium content include:
  • Pumpkin and sunflower seeds — among the richest sources per gram
  • Dark leafy greens — particularly spinach and silverbeet
  • Legumes — black beans, chickpeas, lentils
  • Whole grains — oats, brown rice, quinoa
  • Nuts — almonds, cashews, Brazil nuts
  • Dark chocolate (70%+ cacao)
  • Oily fish — salmon and mackerel
A varied, predominantly whole-food diet is the foundation. Supplements and IV delivery are relevant when dietary approaches are insufficient or absorption is compromised.

Magnesium supplementation: forms and considerations

Not all magnesium supplements are equally absorbed. Magnesium glycinate and magnesium citrate are generally considered to have better bioavailability than magnesium oxide, which is cheaper to produce but less well absorbed. The form matters if you are supplementing.

At high doses, oral magnesium can cause loose stools — this is the mechanism behind some laxative products that contain magnesium. If this occurs, reducing the dose or switching form usually resolves it.

IV magnesium, as part of a broader nutrient infusion such as a Myers cocktail, delivers magnesium directly into the bloodstream. This is relevant where absorption is a concern or where rapid replenishment is clinically appropriate. As with all IV decisions at Nandish, this is discussed in the context of each individual's clinical picture rather than applied uniformly.

A practical note on sleep and magnesium
If you are sleeping poorly and wondering whether magnesium might be relevant, it is a reasonable question to explore — but worth contextualising alongside everything else that influences sleep: your caffeine cut-off time, your bedroom environment, your screen habits in the hour before bed, your stress levels, and whether there are other physical factors (like sleep apnoea or pain) that a clinician should assess.

Magnesium is one of the simpler places to start because it is low-risk and dietary improvement costs very little. If you want a clearer picture of your actual magnesium status, a clinical assessment can provide that.

✨B12 Explained: Why It Gets So Much Attention✨

10/6/2026

 
Picture
Vitamin B12 is one of the most frequently mentioned nutrients in wellness conversations — and one of the most frequently misunderstood. It appears on the ingredient lists of energy drinks, in the menus of IV clinics, and in the conversations of people who have been told their B12 is low and are trying to understand what that means.

This post is an honest look at what B12 actually does, why deficiency develops, who is most at risk, and what the investigation and management pathway looks like — including where injections and IV delivery sit in that picture.

What vitamin B12 is and what it does:
Vitamin B12 (cobalamin) is a water-soluble B vitamin that the human body cannot produce on its own — it must come from diet or supplementation. It is found naturally in animal products: meat, fish, dairy, and eggs. Plant-based sources of B12 are limited to certain fortified foods and some fermented products; strict plant-based diets carry a meaningful risk of deficiency without supplementation.

B12 is involved in several processes that matter considerably for day-to-day function. It is essential for the production of red blood cells — a deficiency can lead to megaloblastic anaemia, in which red blood cells become large and inefficient. It plays a central role in nerve function and myelin sheath maintenance — the protective coating around nerve fibers. And it is required for DNA synthesis and cell division.

This is why B12 deficiency can present with symptoms that seem varied and diffuse: fatigue, cognitive fog, tingling in the hands and feet, balance disturbances, and mood changes can all be associated with inadequate B12 status. These are significant symptoms — and they can develop gradually over months or years before a deficiency is identified.

Why deficiency develops:
B12 deficiency tends to develop through one of two main mechanisms: inadequate intake, or inadequate absorption.

Inadequate intake is most common in people following strict plant-based diets without supplementation or fortified foods. It can also occur in older adults who eat less overall.

Inadequate absorption is a more common driver in many clinical presentations. The absorption of B12 from food requires a protein called intrinsic factor, produced by the stomach lining. Conditions that reduce intrinsic factor production or damage the stomach lining — including autoimmune gastritis (which leads to pernicious anemia), long-term use of proton pump inhibitors or metformin, and certain gastrointestinal surgeries — can impair B12 absorption even when intake is adequate. This is clinically important: someone with an absorption problem who only takes oral B12 may not resolve their deficiency, because the problem is not getting the B12 in — it is absorbing it.

Who is most at risk in an Auckland context?
  • People following vegan or strict vegetarian diets without reliable supplementation or fortified food intake
  • Older adults — intrinsic factor production can decline with age
  • People taking proton pump inhibitors (PPIs) long-term for acid reflux — widely prescribed in New Zealand
  • People taking metformin for blood sugar management — metformin reduces B12 absorption over time
  • Those with a history of gastrointestinal surgery
  • People with autoimmune conditions affecting the stomach
B12 deficiency can also occur without obvious risk factors, which is why clinical testing is the only reliable way to assess status.

How deficiency is investigated
Serum B12 is the standard initial test, available through a GP or a clinic like Nandish. It is worth knowing that serum B12 can be in the "normal" range while active B12 deficiency exists — in some cases, a methylmalonic acid (MMA) or homocysteine test gives a more sensitive picture of functional B12 status. If you have symptoms that suggest B12 deficiency but a standard test comes back in range, this is worth discussing with your clinician.

Oral supplementation vs injection vs IV
This is where the clinical picture matters considerably.

For people with B12 deficiency caused by inadequate dietary intake and normal absorption capacity, high-dose oral B12 supplementation is often effective — at sufficient doses, a small percentage of B12 can be absorbed through passive diffusion even without intrinsic factor.

For people with absorption problems — including pernicious anemia — intramuscular (IM) injection or IV delivery bypasses the digestive system entirely and is typically the appropriate pathway. In New Zealand, B12 injections (hydroxycobalamin or cyanocobalamin) are commonly used in primary care for this purpose.

IV delivery of B12 as part of a broader nutrient infusion is something we discuss at Nandish in the context of each individual's situation. It is not automatically superior to injection; the right route depends on why the deficiency has developed and what the person's clinical needs are.

As with all nutrient-related conversations at Nandish: we test first, understand the cause, and then discuss the most appropriate pathway together.

What to do if you are concerned about your B12
If you are experiencing persistent fatigue, cognitive fog, or neurological symptoms — particularly if you follow a plant-based diet or take medications associated with reduced B12 absorption — it is worth investigating. A blood test is straightforward and gives you a baseline to work from.

We are happy to include B12 as part of a broader wellness assessment at Nandish. If you would like to have that conversation, our initial consultation is the right place to start.

✨Vitamin D and New Zealand Winters: What the Science Says✨

6/6/2026

 
Picture
New Zealand has a reputation as a sun-drenched country, which makes vitamin D deficiency feel like something that happens elsewhere. The data tells a more complicated story — one that is particularly relevant to Auckland residents during the winter months of June through August.

This post looks at what vitamin D actually does, how deficiency develops in a country with significant sunshine hours, who is most at risk in an Auckland context, and what investigation and support might look like if you are concerned.

What vitamin D does — and why it matters
Vitamin D is a fat-soluble nutrient that functions more like a hormone than a conventional vitamin. It is involved in calcium absorption and bone mineralisation — the role most people are familiar with — but its influence extends considerably further. Vitamin D receptors are present in virtually every tissue in the body, and it is studied in the context of immune function, muscle health, mood regulation, and cardiovascular wellness.

The body produces vitamin D when ultraviolet B (UVB) radiation from sunlight hits the skin and triggers a conversion process. A smaller amount can be obtained through diet — primarily from oily fish, egg yolks, and fortified foods — but dietary sources alone are rarely sufficient to maintain adequate levels in populations with limited sun exposure.

Vitamin D deficiency in New Zealand: what the research shows
New Zealand is not immune to vitamin D deficiency. Research published in the New Zealand Medical Journal and drawn on by Te Whatu Ora has identified sub-optimal vitamin D levels as common in New Zealand, particularly in winter and among specific population groups.

The reason comes down to the angle of the sun. During Auckland winters, the UVB radiation reaching the skin is significantly weaker than in summer — often insufficient to trigger meaningful vitamin D synthesis even with reasonable time spent outdoors. The latitude matters: Auckland sits at approximately 37 degrees south, and from late autumn through early spring, UVB levels drop considerably.

Time indoors, sunscreen use (which blocks UVB), darker skin pigmentation (which requires longer sun exposure for equivalent synthesis), and older age (which reduces conversion efficiency) all compound the picture.

Who is most at risk in an Auckland context?
Population groups with higher rates of vitamin D deficiency in New Zealand include:
  • People who spend most of their time indoors — office workers, shift workers, those with mobility limitations
  • People with darker skin — Māori, Pacific and South Asian communities, who require significantly more sun exposure to produce equivalent amounts of vitamin D
  • Older adults — skin becomes less efficient at vitamin D synthesis with age
  • Pregnant and breastfeeding women — vitamin D requirements increase during pregnancy
  • People with obesity — vitamin D is fat-soluble and can be sequestered in adipose tissue, reducing circulating levels
  • Those with limited dietary variety or who follow strict plant-based diets with no fortified foods
This is not an exhaustive list — it is a starting point for identifying who might benefit from investigation. Deficiency can occur without any of these factors being present.

What low vitamin D might look like
Vitamin D deficiency rarely announces itself with a single clear symptom. The picture tends to be diffuse: fatigue that does not resolve with adequate sleep, muscle weakness, low mood or a sense of flatness, increased susceptibility to illness during winter, and — in more pronounced cases — bone or muscle pain.

The challenge is that these symptoms overlap significantly with many other things: low iron, thyroid dysfunction, poor sleep, chronic stress. This is why a blood test — measuring serum 25-hydroxyvitamin D — is the only reliable way to know whether vitamin D is actually a factor. Supplementing without testing means guessing.

What adequate vitamin D levels look like
Reference ranges vary between laboratories, but most current guidance considers serum 25(OH)D below 25 nmol/L as deficient, between 25 and 50 nmol/L as insufficient, and above 50 nmol/L as adequate for most people. Optimal levels for certain groups may be higher. Your clinician can help interpret your result in the context of your full picture.

It is also worth knowing that vitamin D toxicity is possible at very high supplemental doses over time — this is one reason testing before high-dose supplementation is clinically appropriate rather than guessing based on symptoms.

How is vitamin D deficiency managed?
The primary management approach for most people is oral supplementation — vitamin D3 (cholecalciferol) is generally considered the most effective form. The appropriate dose depends on the degree of deficiency identified on testing, the person's risk factors, and their current levels. Doses range from modest maintenance amounts to higher loading doses for significant deficiency, with retesting after a period of supplementation to confirm response.

Sunlight exposure — in Auckland, this means getting outside around midday in spring through autumn when UVB levels are adequate — also contributes meaningfully and has benefits beyond vitamin D synthesis.

Dietary sources (oily fish, eggs, fortified milks and cereals) can support but rarely replace supplementation in people with identified deficiency.

At Nandish, vitamin D is one of the nutrients we look at as part of a broader wellness assessment. If injection or infusion delivery is clinically appropriate — for example, where absorption via the oral route is compromised — this is something we may discuss. The starting point, always, is testing.

What to do if you are concerned
If you are experiencing persistent fatigue, low mood, or frequent illness through the Auckland winter — and particularly if you fall into one of the higher-risk groups described above — it is worth having a conversation with a clinician. A simple blood test can tell you whether vitamin D is part of the picture. That is a much better starting point than adding supplements without evidence.

At Nandish, this kind of conversation is exactly what our initial consultation is designed for. We look at the full picture — not just one nutrient in isolation — and work with you from there.
