The Active Ingredient Is: Glutamic acid

glutamic acid is a nonessential amino acid that serves as a neurotransmitter precursor and can convert to glutamine when needed during times of stress or intense activity.

This product provides glutamic acid in a vegetarian capsule form, with plant-based capsules and common inactive ingredients like rice flour and silica.

What Does Glutamic acid Do?

glutamic acid is part of nerve communication as a neurotransmitter precursor and helps with the production of GABA, an inhibitory neurotransmitter. It also serves as a main energy source for gut lining cells and can help with amino acid production in the gut, supporting everyday bodily functions.

What's more, it helps with glutathione synthesis during exercise, which is relevant for muscle function and recovery in everyday body function.
