DHEA benefits are limited, and anti-aging proof is weak
DHEA is a real hormone precursor, and its level falls with age. But that does not prove oral DHEA improves aging, energy, muscle, or libido for most people. Human evidence supports a few narrower uses and raises real safety questions.
NAD supplements help cells produce energy (but anti-aging proof in humans is still limited)
NAD supplements like NMN and NR help cells produce energy and may fight aging. Learn how they work, what science says about their benefits, and the risks.
NAD supplements raise NAD in the body – health gains are not established yet
Nicotinamide adenine dinucleotide, or NAD, is a helper molecule that cells use for energy, DNA repair, and body clock control.…
Vitamin D may help cells age more slowly
Vitamin D may slow cellular aging by preserving telomere length, a new study finds. Learn about the benefits for DNA, proper dosage, and potential risks.
Low vitamin D and K levels tripled heart disease risk in one study
According to a doctor (A.M.) about another doctor (Résimont) about another doctor (Eric Müller) : IN PRACTICE: If deficient (<60):…
