✅ Excellent NAD+ Precursor - In fact, NMN can go directly into cells and convert to NAD+ in one step. ✅ NMN promotes health by activating SIRTUINS, a group of longevity genes that are responsible for repairing DNA damage and regulating or inhibiting other genes. SIRTUINS are dependent on NAD+, which means they cannot function if NAD+ is not in sufficient supply. This is why NMN is so important, as it is the most effective way to increase and support NAD levels. ✅ Early studies show that NMN can promote a healthy heart, blood flow, eyes, brain, bones, muscles, and immune function. NMN also supports strength, endurance, and energy production. ✅ GMP Certified Manufacturing - Made in the USA in a GMP certified facility.
