NAD (Nicotinamide Adenine Dinucleotide) is a molecule naturally produced by our bodies that plays a crucial role in cellular energy metabolism. Its active form, NAD⁺, regulates proper energy use within cells. However, NAD production declines with age, contributing to organ aging—especially in the brain—and increasing susceptibility to diseases, including chronic age-related conditions.

Scientific studies have shown that NAD therapy can enhance cognitive functions, improving learning and orientation skills. Many users report relief from brain fog after treatment. Oral NAD supplements are ineffective as they cannot pass through the gastric barrier intact, making intravenous administration the only effective method. At Only Health, certified professionals deliver NAD intravenously with care and high-quality standards.
