NAD+ Pro provides 15 grams of pure NAD+ powder to support energy, mood, appetite control and healthy metabolism.

  • Supports increased energy
  • Supports healthy mood
  • Supports appetite control and metabolism

Supports Energy Levels. NAD+ helps support energy levels. Because your body requires NAD+ to efficiently process food into energy, low NAD+ levels may impact how energized you feel. (1)

Supports Metabolism. NAD+ is an essential metabolite and coenzyme for multiple metabolic pathways and cellular processes. The ability of NAD+ to form its reduced version, NADH, is critical for all metabolic reactions in humans, including turning food into fuel. Aging typically causes slowing metabolism, and NAD+ may be able to help. (2)

Supports Healthy Mood. NAD+ may increase serotonin levels, our “feel good” neurotransmitter that supports healthy moods. (3)

Simply close tightly after each use.
L-theanine generally does not have side effects, but 5-HTP may cause nausea, heartburn, gas or loss of appetite. High doses of 5-HTP (which are not found in this formula) can cause serotonin syndrome, a dangerous condition caused by too much serotonin in the body.
