NAD+ boost shown, lifespan benefit untested
The description states that NAD+ levels naturally fall with age and that a January 2026 study showed NMN and NR can double circulating NAD+ in two weeks. It calls this part solid. However, it says no human trial has ever shown these compounds extend lifespan, and the longest study lasted only twelve weeks.

Basics backed by decades of human research
The description contrasts the supplements with basics: vitamin D, omega-3, magnesium and adequate protein are said to be backed by decades of human research. It lists red flags such as “reverse” without specifying what, mouse data presented as human proof, and testimonial-driven claims.
