Longevity Science
Longevity is the category with the widest gap between what is marketed and what has been shown in people. Most of it rests on cell or animal work, or on correlation. That is where to start reading.
Almost everything sold in this category rests on evidence that is preclinical, which is to say cells or short-lived animals, or observational, which is to say correlational in humans. Neither is worthless and neither is the same as showing that a compound extends healthy life in people. The gap between those two things is where most longevity marketing lives.
The questions that separate a serious product from a confident one are consistent. What population was studied - yeast, mice, or humans? What endpoint was measured - a biomarker that moved, or an outcome someone would notice? Over what duration, and at what dose relative to the one in the capsule? A compound with striking mouse data and no human outcome trials is not disqualified, but it should be described that way, and a brand that describes it that way is telling you more than one that does not.
