Product Overview


  • Amino Acid Supplement

L-Aspartic acid plays a vital role in energy production. It is one of the components necessary to move high energy NADH molecules from the main body of a cell to its mitochondria, or primary energy-production areas. Once there, the NADH is used to generate ATP, the energy fuel that powers all the cell's activities. Besides helping with energy production, L-Aspartic acid is a major excitatory neurotransmitter.

Suggested Use

1/4 to 1/2 teaspoon daily between meals.

Have sense that strength of reaction to this product depends a lot on diet, feels good but not very noticeable for me. Haven't tried going above 1/2 tsp due to neuro-excitatory.

Thanks for your feedback!
