Why winter hits you harder than it used to
It isn't bad luck, and it isn't in your head. Shorter days, less sun, more time indoors with whatever's going around — and a defence system that, from your mid-40s on, simply reacts more slowly than it did at 30.
You know the pattern:
-
You catch what the grandkids bring home, every time
-
A "quick cold" knocks you flat for a week
-
You're run-down by Friday and it takes the weekend to recover
-
You reach spring having been sick more than once
Lifeguard Immune was formulated by Dr Roderick Mulgan to support your defences before you feel run-down — steadily, every day, right through the season.
Why Lifeguard Immune?
-
Zinc
-
Supports normal immune system function and is one of the key nutrients adults need to keep topped up.
-
Vitamin D
-
Supports immune function and can be harder to maintain during the darker winter months.
-
Quercetin
-
A plant-derived polyphenol included as part of Lifeguard Immune’s targeted formulation.
-
Plus 5 other selected immune-support ingredients.
Eight ingredients. One clear purpose.
Most immune supplements pick one ingredient and dose it heavily. Lifeguard Immune works differently — eight ingredients chosen because they support your immune response through different pathways, working together rather than in isolation.
Dr Mulgan selected each one based on clinical evidence for adults over 45, where the immune system becomes less efficient rather than less present. No gimmicks. No mega-doses. A balanced formula designed for daily, cumulative support.
Vitamin C
100mg as Ascorbic Acid
The foundational immune nutrient. Supports the function of immune cells, acts as an antioxidant under oxidative stress, and is used up quickly when the body is under physical stress. The form used here — ascorbic acid — is well-absorbed and well-studied.
Vitamin D3
500IU · 12.5mcg Cholecalciferol
New Zealand research consistently shows that a large proportion of adults over 45 are deficient in vitamin D, particularly through winter. D3 is the most bioavailable form and plays a direct role in regulating immune cell activity — not just bone health as commonly assumed.
Copper
500mcg as Gluconate
An often-overlooked immune mineral. Copper is required for the normal functioning of immune cells. The gluconate form is well-absorbed. Low copper status is more common in older adults, which makes dietary intake worth supporting.
Selenium
25mcg as Selenomethionine
A trace mineral essential for the production of selenoproteins that regulate immune and inflammatory responses. Selenomethionine is the most bioavailable organic form. New Zealand soils are selenium-poor, making dietary intake unreliable for many New Zealanders.
Zinc
7mg as Citrate
One of the most clinically studied immune minerals. Zinc is required for the development and function of immune cells at multiple levels. Zinc citrate is gentler on the stomach than zinc sulfate and better absorbed than zinc oxide, which is common in cheaper formulas.
ElderMune® Elderberry
200mg · equiv. 13g dry Sambucus nigra
A standardised, concentrated elderberry extract — not generic elderberry powder. ElderMune® is a branded form with consistent anthocyanin content, traditionally used to support the body's immune response through the season. The 13g dry equivalent reflects a meaningful concentration.
Andrographis
100mg · equiv. 1,000mg dry Andrographis paniculata
A well-researched botanical traditionally used in Asian medicine to support immune resilience. The concentrated extract delivers a meaningful dose from a small capsule.
Plus Quercetin — the eighth layer of support
Quercetin Powder 250mg (equiv. 237mg Quercetin) rounds out the formula as a broad-spectrum antioxidant flavonoid that helps support a normal anti-inflammatory response and normal immune cell function- particularly relevant for the everyday low grade inflamation that becomes more common after 45. It supports immune cell function and helps modulate the inflammatory response — particularly relevant for the chronic low-grade inflammation that becomes more common after 45. Together, these eight ingredients address immune support at the cellular level, the antioxidant level, and the inflammatory level — a complete picture rather than a single-ingredient approach.
How to tell it's working
What "working" actually feels like
Here's the honest truth most immune brands won't tell you: good immune support is mostly invisible. You can't feel a cold you didn't get. So don't judge Lifeguard Immune by a single week — judge it across the season, the way you'd judge any preventative habit.
What our subscribers tell us they notice over four to eight weeks:
-
More steady energy — less of that run-down, wrung-out feeling by week's end
-
Bouncing back faster when they do catch something
-
Getting through a winter that used to mean two or three knock-downs with far fewer, and milder
-
Quiet confidence around travel, grandkids and busy seasons
That's why we give the first month free, and why consistency matters more here than with almost anything else: the payoff builds across the whole winter, not on day three.

Who it's for?
This is for you if any of these sound familiar:
-
You catch colds and flu more easily than you used to, and they hang around longer
-
You travel — for work or family — and often come home unwell
-
You're around grandchildren, busy offices or seasonal exposure and want reliable daily backup
-
You've tried vitamin C or echinacea on their own and found them underwhelming
This is a complete daily formula, not a single ingredient you reach for once you already feel something coming on.

What our subscribers are saying about us...
Trevor S., 70 · verified subscriber
I've been on Lifeguard Immune for four months now, and I feel the difference. I'm 70 and used to feel nervous about every winter, but this year I stayed healthier than I can remember. Even when people around me were sick, I managed fine. I'm very pleased with the results.
Michaela B., 59 · verified subscriber
I'm 59 and travel frequently for work, which used to mean I picked up colds easily. Since taking Lifeguard Immune, I've noticed I can get through trips without falling sick. Even when I did catch something mild, it passed quickly. It's reassuring to feel more protected and resilient.
L.C., 55 · verified subscriber · healthcare worker
I work in healthcare and am constantly exposed to people who are unwell. I'm 55 and usually get two or three nasty colds every year. Since taking Lifeguard Immune, I've managed to stay healthy through some very busy months. I can't prove it's all down to this, but I genuinely feel like it's helped keep me well.
Margo C - verified subscriber
I have been taking Immunity now for around a year. I have not had any problems in that time . I am basically well though I do have a Leaky gut and sinus allergy to certain foods .
My key support alongside Immunity and other herbal support is REn Xue qigong practice and life development. I feel this is a good combination! alongside being as calm , relaxed and joyous as I can !!
