NAD+ (nicotinamide adenine dinucleotide) is an essential coenzyme found in every living cell that helps turn food into energy and supports basic cellular functions.
What NAD+ Does
• Energy Production: It acts as an electron carrier during cellular respiration and metabolism, helping convert nutrients into ATP (cellular energy).
• DNA Repair & Maintenance: It fuels enzymes like PARPs and sirtuins that repair damaged DNA and regulate stress responses.
• Cellular Health: It supports mitochondrial function, immune health, and circadian rhythms.
Why NAD+ Levels Change
• Age-Related Decline: NAD+ levels naturally drop as people age—often cutting in half by middle age.
• Impact of Decline: Lower levels are linked to reduced energy, slower cell repair, and various age-related metabolic and cognitive shifts.
Ways People Boost NAD+
• Lifestyle Habits: Regular exercise, consistent sleep schedules, and lower caloric intake can naturally support NAD+ production.
• Precursor Supplements: Over-the-counter vitamin B3 derivatives like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) help the body build NAD+.
• Therapies: IV infusions and injections are offered at wellness clinics, though large-scale human clinical evidence for direct anti-aging or therapeutic claims remains limited.
• Safety & Risks: Precursors and therapies can have mild side effects (like nausea or flushing), and boosting NAD+ is approached with caution or avoided by individuals with certain active infections or histories of cancer, as NAD+ pathways can theoretically influence cell growth.
