Are NAD+ Supplements a Longevity Hack or an Expensive Placebo?
"It's more than likely that the NAD+ supplement craze has already crossed your path. The Biebers have infused it. Joe Rogan has podcasted about it. Gwyneth Paltrow swears by it and, of course, sells her own Youth-Boost NAD+ Peptide Rich Cream. NAD+ is the latest biohacker's darling. It's in longevity clinics and the wellness aisle, in your dietary supplements and your topical skin care."
"Some studies suggest that many of the biological changes associated with aging don't suddenly emerge with old age; they begin much earlier, often in our thirties and forties, and are closely tied to chronic conditions like neurodegeneration, metabolic dysfunction, and cardiovascular disease. "Throughout any decade of life, people want to function at what they see as their optimal level," board-certified internist and longevity specialist Amanda Khan tells WIRED. That desire has pushed attention toward compounds that support basic cellular processes. Like NAD+."
NAD+ (nicotinamide adenine dinucleotide) is a naturally produced coenzyme that helps drive cellular energy production and supports immune function. Interest in NAD+ supplementation has expanded into celebrity endorsements, wellness products, and longevity clinics as part of a prevention-oriented approach to aging. Many biological changes linked to aging begin in the thirties and forties and contribute to neurodegeneration, metabolic dysfunction, and cardiovascular disease. Attention toward NAD+ reflects a desire to maintain optimal function across decades by supporting basic cellular processes. NAD+ is produced inside cells from precursor molecules, and researchers describe precursor-based approaches as accessible, seemingly safe, and potentially capable of long-term effects.
