What are “healthy ageing supplements”?
Healthy ageing isn’t about doing everything—it’s about supporting what matters most: how you feel day to day, how well you recover, and whether your routine is sustainable. Many over-45s start with a few common goals: more consistent energy, stronger immune confidence, and better sleep.
What changes after 45?
- Energy can feel less predictable (busy lives, stress, changing routines)
- Immunity can feel more “seasonal” than it used to
- Sleep can become lighter, more broken, and harder to “bounce back” from
How to choose a supplement stack (without overwhelm)
Look for:
- Credibility: clear formulation logic and expert leadership
- Simplicity: fewer products, clearer routine
- Quality & origin: NZ-made preference is common among over-45 shoppers

Resilience you can feel confident in

What customers say
The luckiest thing I ever did was to start reading Doctor Roderick Mulgan’s book ‘The Internal Flame’. His background research make so much sense to me that I’ve been recommending it and ‘The Essentials’ range to anyone who will listen to me! It is the most insightful Health Supplement I have come across, significantly stabilising my ongoing (25 years) of health issues relating to inflammatory disorders, primarily Rheumatoid Arthritis, and leaving me with much more vitality overall.
Having taken Lifeguard Essentials for over two years now, I really notice them when I forget to take them for awhile. An old knee injury plays up. I feel more general soreness after exercise. My joints are noisier. It’s amazing how quickly that goes away when I get back on the wagon. Thanks for a great product. It really helps me.
I’m an active 55. I surf, workout, dive, row, and ride my mountain bike hard. I am also a busy professional. Recovery time started to creep up over the past few years. Since taking LifeGuard on the recommendation of a neighbour, I have noticed that some of the old niggles have gone away, and I seem to be able to push through and recover from my activities quicker than I was. I have been taking LifeGuard for three months now, and am not going to stop. I’m a massive fan. Thank you! — BG
I started taking Lifeguard Essentials after reading an article in Life and Leisure. At the time I was suffering from inflamed tendons in my wrist. I had been going to physio, doing exercises and acupuncture. After completing my first bottle I noticed less discomfort and pain in my wrists. Now a few months later I no longer have any pain. Thank you for a great product. It has made a huge difference to my wellbeing — PL
I am a great believer in nutritional supplements and was impressed that Dr Mulgan was recommending them so decided to make a change and try them out. Because I have been taking other products I am not noticing a huge difference. But know if I stopped I would. In my 70s and on no medication I am aware in this covid climate I need to keep my immune system functioning well. — MS
