Product Description
D-Leucine act as a seizure inhibitor, probably even more efficient that L-isomer.
D-Leucine has a very interesting attribute; it is not included into mammalian proteins. This characteristic, along with the discovered anti-seizure action could become a part of the vegan diet debate, which is so active in our times. The specific amino acid is found in food and it accumulates in traces in the brain; vegan supporters can further continue the presented investigation to suggest more advantages of a mammalian free diet for the modern world, which meets moral requirements as well as health ones.
