An independent review site focused on health, longevity and performance supplements for adults over 40.
Prime Vitality Lab is an independent publishing project, not a clinic, a laboratory or a supplement manufacturer. We research and review health and longevity products so that readers over 40 can make informed decisions before they spend money — especially in categories where marketing tends to outrun the evidence.
We pick supplements that people are actively searching for, then we do the work most review sites skip: we study the published research behind the key ingredients, read through real customer feedback across multiple sources (including the critical reviews), and write up an honest verdict that includes the downsides, the side effects and the people who should not buy the product. We are an affiliate site — we earn a commission when you purchase through our links, at no extra cost to you — but our editorial verdicts are written independently of that. A full explanation is in our editorial policy.
We are not doctors, and nothing on this site is medical advice. We do not manufacture or sell supplements ourselves. We are not affiliated with Advanced Bionutritionals or any other brand we review. When a product carries real medical risk — for example one that contains hormones or affects blood sugar — we say so plainly and tell you to consult your physician first.
Prime Vitality Lab is operated as part of an independent digital media and marketing practice based in Portugal, serving Portuguese- and English-speaking audiences. For editorial questions, corrections, partnership or any other matter, reach us directly — details on our contact page.
