Our recommended dosage is two 350 mg capsules of NMN per day. Studies have shown positive health benefits within a range of doses. Some individuals have experienced benefits with doses as low as 250 mg of NMN per day, while others have found positive outcomes with doses of up to 1,200 mg daily. People in higher age groups can benefit from higher dosages of NMN, but research is pending. Younger individuals may find themselves sufficient with one capsule a day.
