SUPPLEMENTS: Your Supplement Shelf is Full of Expensive Guesswork
Here's what actually works
Part of The Longevity Series for Women Over Forty
A woman at one of my talks looked at me with polite scepticism when I mentioned creatine and said, “isn’t that what bodybuilders take?” She gestured vaguely, as though conjuring someone enormous in a car park at midnight.
I told her yes and also that it’s one of the most extensively researched molecules in human physiology, with quietly extraordinary benefits for women in midlife, and that the bodybuilder association is a marketing problem, not a scientific one. She bought some the following week. As she should have.
Let’s be clear about what supplements are and what they aren’t. They won’t compensate for chronic sleep debt, a diet built on beige foods and good intentions, or stress that’s been running at amber for six years. They also aren’t nonsense. The reflexive scepticism that lumps clinically validated compounds in with crystals that “align your frequencies” is equally unhelpful and arguably more expensive, if you price in the consequences of the deficiencies you’ve decided to feel sceptical about instead.
At their best, supplements amplify an already decent foundation. They fill gaps that even a well-constructed diet leaves, particularly after 40 when absorption changes, hormonal demands shift, and the margin for running on empty gets measurably smaller. The body you are living in now requires more nutritional precision than the body you were living in at thirty-two. This is just a biological fact and the sooner you stop treating your nutritional needs as something to be modest about, the better everything gets for you.
Food builds the foundation, supplements do the fine-tuning.
Supplements aren’t shortcuts they’re amplifiers to great health. They are precise interventions that help your biology run on something closer to premium fuel. And as you intimately know, once you hit your 40s and 50s, the margin for error gets smaller. Sleep debt, stress, hormones, wine they all start charging interest at the higher rate.
Supplements can’t outsmart a bad lifestyle, but they can make your healthspan measurably stronger as you age by ensuring your body is getting what it truly needs during a period when your requirements have quietly but significantly changed.
Why the supplements I recommend work together
What these compounds share isn’t marketing. It’s science and mechanism. They work through the same systems that govern ageing itself:
Energy production (ATP, mitochondria)
Inflammation control (NF-κB, cytokine balance)
Cell repair and gene signalling (sirtuins, NAD⁺, BDNF)
Together, they strengthen what matters most: your metabolic resilience, your brain health and your capacity for regeneration. Because longevity, at this age, isn’t about chasing your youth. It’s about maintaining your vital capacities like your ability to think clearly, move freely, and wake up every day with energy to spare rather than starting each morning already in deficit.
What this really comes down to is agency. In midlife, you don’t have time for gimmicks or guesswork and you’re looking for tools that respect your biology, not fight against it. The supplements I’ve chosen aren’t about fixing you. They’re about supporting the systems that carry you through your day, your work, your relationships, your ambitions. They help you stay regulated, clear-headed, and steady in a world that demands more from you now than ever.
There is something quietly empowering about knowing you can nourish the parts of yourself that have been overextended, overlooked, or running on empty for too long. These aren’t magic bullets. They are thoughtful interventions - small, strategic inputs that help you show up as the woman you want to be: energised, resilient, and connected to yourself in a way that feels strong, grounded, and entirely your own. Not just now. Even when you’re properly rattling in your old lady bones.
I’m not handing out hacks here. These, my friends, are your maintenance crew.
