An Evidence-Based Supplement Brand from NZ
Lifeguard Health exists because supplements can be better. Rather than chasing fads or mega-doses, Dr Mulgan builds each formula from the ground up, using research on ingredients, dosage and long-term safety. That’s what we mean by evidence-based supplements from New Zealand.
About Lifeguard Health and Doctor Mulgan
An evidence-based supplement brand in NZ, created by a practising medical doctor.
Lifeguard Health is a New Zealand supplement brand founded by Dr Roderick Mulgan, a GP with over 25 years of clinical experience and a special interest in healthy ageing, inflammation and immunity.
Our mission is simple: to provide evidence-based supplements in NZ that genuinely support people 45+ to stay active, independent and well for longer. Every Lifeguard formula is guided by clinical research and grounded in what Dr Mulgan has seen work in real patients over decades of practice.
Meet Dr Roderick Mulgan
Dr Roderick Mulgan is the medical mind behind Lifeguard Health.
He’s a Fellow of the Royal New Zealand College of General Practitioners with more than three decades of experience in general practice, aged care and preventative medicine.
Over the years, Dr Mulgan has:
-
Developed a large multi-doctor practice caring for residents in aged-care facilities
-
Seen first-hand how lifestyle and diet drive inflammation, disease risk and the ageing process
-
Become a published author on immunity, inflammation and healthy ageing, including The Internal Flame and Build Your Immunity for Life
Lifeguard Health grew out of this experience. Dr Mulgan wanted to give people a practical way to apply the science he writes about—through targeted supplements that support sleep, immunity, energy and long-term health.
Clinically guided formulas
Our products are based on published research and informed by Dr Mulgan’s clinical experience with real patients—not marketing hype.
Designed for healthy ageing 45+
Lifeguard supplements are created for people in midlife and beyond, whose bodies and lifestyles are different to those in their 20s.
Targeted, not “everything in one pill”
Each product focuses on specific challenges—such as sleep quality, immune resilience or everyday inflammation—to avoid unnecessary ingredients and noise.
Made in New Zealand
Our supplements are made in NZ, following strict quality standards, so you can trust what’s on the label is what’s in the capsule
How Our Doctor-Formulated Supplements Are Created
Every Lifeguard product follows a simple but rigorous process:
Step 1: Research & clinical need
Dr Mulgan starts with a real-world problem he sees in his patients—poor sleep, immune fragility, joint discomfort, low energy—and reviews the latest research on nutrients and plant compounds that can help.
Step 2: Evidence & dosage.
From there, he selects ingredients and doses that are supported by human studies (where possible), focusing on what is effective and sustainable over the long-term, not just trendy.
Step 3: Real-life fit
Finally, the formula is shaped around everyday use: once-daily dosing where possible, gentle on the stomach, and suitable as part of a long-term plan to support healthy ageing.
Who We Help
Lifeguard Health is for people who want to stay strong and independent as they age - not just treat problems when they’re already entrenched.
Our supplements are especially suited to:
-
Adults 45+ who want to protect their long-term health
-
People who feel the early signs of ageing—stiff joints, low energy, slower recovery
-
Those who want natural, evidence-guided support alongside a healthy lifestyle
-
Anyone who values supplements created by a real doctor, not a marketing team
If you’re looking for a supplement brand you can trust, you’re in the right place.

Why People Trust Lifeguard Health
Thousands of New Zealanders use Lifeguard supplements as part of their healthy ageing routine.
“After 50 years in pharmacy, I’m picky about what I take. Lifeguard Essentials covers all my needs and I feel the difference, especially in my joints.” — L.C., Southland, NZ
“When I stop taking Essentials my old knee injury plays up and I feel more general soreness after exercise. It’s amazing how quickly that goes away when I get back on the wagon.” — S.C., NZ
“I enjoy Dr Mulgan’s articles—they make the science easy to understand—and Lifeguard Health gives me a simple way to act on it.” — Customer, NZ
I’d tried an OTC sleep aid and hated the groggy mornings. Lifeguard Sleep is different—no wired or woozy feeling, just steady sleep. I’m getting up earlier for a walk and I’m sharper at work. Subscription makes it one less thing to think about.
— Dave M., 62, Christchurch • Using for 3 months
I’m not a perfect sleeper, but this has made nights noticeably calmer. I pair it with a quick wind-down (no phone, dim lights) and I’m usually out in 20–30 minutes. I still wake once sometimes, but I fall back asleep much faster and feel way better in the morning.
— Sarah L., 47, Wellington • Using for 1 month
“I’m an active 55—surf, workout, dive, row, ride. Recovery time had crept up. After three months on Lifeguard, old niggles have gone and I can push through and recover faster. I’m a massive fan.”
— B.G., Wellington, NZ.

For us, “evidence-based” means our formulas are guided by research and real-world clinical experience - not just trends. Dr Mulgan reviews human studies on nutrients and plant ingredients, chooses doses that have been shown to help, and shapes products around long-term use rather than quick fixes.
