This is probably the most honest, and most evolved, take I’ll give you on this list. I’ve been taking Youth & Earth Preservage, 410mg, a blend of resveratrol, curcumin, quercetin and BioPerine for over a year, and my reasons for taking it have genuinely changed over that time — which I think is worth being upfront about rather than pretending my views never shift.
Why resveratrol became famous in the first place
Resveratrol, a compound found in red grape skins and red wine, became one of the biggest names in longevity supplements on the back of research suggesting it activated sirtuins — proteins thought to mimic some of the benefits of calorie restriction, which is one of the few interventions reliably shown to extend lifespan in animals. It was an exciting, elegant idea, and it’s why I started taking this product in the first place.
Why I’ve become more skeptical of that specific story
I think it’s important to update your view when the evidence changes, so here’s the honest picture as it stands now. The original sirtuin-activation findings turned out to be partly an artifact of how the early lab experiments were run, and later, more precise research (including CRISPR-based studies) found resveratrol doesn’t actually activate sirtuins the way first thought. The gold-standard test for lifespan effects in animals — a programme testing genetically diverse mice across multiple independent labs — found resveratrol simply didn’t extend lifespan at any dose tested. Human trials have mostly been neutral: one trial giving participants up to 1000mg daily for 16 weeks found no improvement in inflammation and, unexpectedly, a rise in cholesterol. Perhaps most strikingly, a couple of studies found resveratrol supplementation actually blunted some of the cardiovascular benefits people would otherwise get from exercise. None of this means resveratrol is harmful at normal doses — it’s generally well tolerated — but the “activates your longevity genes” pitch that made it famous hasn’t held up well.
Why I still take it
This is genuinely the reason I’ve kept it in my routine: quercetin. It’s a well-studied antioxidant flavonoid with a decent research base for stabilising the cells that release histamine (useful for allergy-type symptoms), general antioxidant and anti-inflammatory activity, and it’s an ingredient of real interest in current “senolytic” research (compounds studied for helping clear old, dysfunctional cells). The curcumin and BioPerine (black pepper extract) combination is also genuinely useful — curcumin is poorly absorbed on its own, and BioPerine substantially improves that absorption, the same principle I covered in my dedicated turmeric post. So while my original reason for buying this product hasn’t held up, the other three ingredients still make a reasonable case for it on their own.
One thing worth knowing if you’re already taking a dedicated turmeric/curcumin supplement (like the one I’ve also written about): there’s some overlap here, since this product includes curcumin and black pepper too. Not a problem, but worth being aware of rather than assuming every ingredient here is entirely additional.
What I’ve actually noticed
Over more than a year, I can’t point to a single dramatic effect, and I think that’s honest to say — this has always felt like a background, general-wellness addition to my routine rather than something with an obvious, noticeable impact the way, say, magnesium or NMN have been for me.
How I take it
One capsule a day, after my evening meal.
A quick safety note
At high doses, resveratrol can act as a mixed estrogen receptor agonist/antagonist, which may be worth discussing with your doctor if you have a hormone-sensitive condition. Quercetin can interact with certain antibiotics, blood thinners like warfarin, and other liver-metabolised medications. As always, check with your doctor if you’re on regular medication or have relevant health conditions.
Should you try it?
I’d frame this honestly: don’t buy it expecting resveratrol to be a longevity miracle, because the current evidence doesn’t support that story as well as it once seemed to. But as a general antioxidant blend, with quercetin and a properly bioavailable curcumin dose included, it’s a reasonable, well-tolerated addition — just go in with accurate expectations rather than the marketing version of resveratrol’s reputation.
