Longevity & Anti-Aging
Longevity and anti-aging claims checked against human studies: supplements, drugs, biological age tests and habits said to slow aging. Each article says what the trials found, how strong the evidence is and where it stops.
-
Not very, for one person. Run one blood sample twice and a biological age test can shift by up to 9 years. What the number can and cannot tell you.
-
Do brain training games work? 11,430 adults trained for six weeks and gained nothing on untrained tests. What the evidence shows, and what helps instead.

The hearing loss dementia link got its first proper trial: 977 adults, three years, hearing aids. Here is what it found, and what the headline number missed.

NMN vs NR, finally tested head to head: in 65 healthy adults both roughly doubled blood NAD+, with no winner. Here is what that does and does not buy you.

PT-141 vs Melanotan 2: one was tested in 1,250 women and carries a safety label. The other has case reports of melanoma and vials that never hold 10 mg.

Spermidine benefits look strong in food studies and weak in capsules: a year-long trial in 100 older adults found no memory gain from the wheat germ pills.

Possibly, but the proof is thin. GlyNAC raised muscle glutathione 164% in a 24-person trial, while a 114-person test at a lower dose found no rise.
-
Red light therapy has real trial support for skin and next-day soreness, and none for fat loss. Here is what the doses, numbers and caveats actually show.
