NAD⁺ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in every living cell, playing a key role in numerous essential biological functions. However, NAD⁺ levels naturally decline with age, which can impact energy production, cognitive performance, and immune system function. Supplementing with NAD⁺ can help restore these levels, supporting overall health and vitality. Double Wood Supplements’ NAD⁺ formula delivers over 95% pure NAD⁺, offering a highly effective way to replenish this critical compound as the body’s natural production decreases with age.
