Don’t be startled by the name. Amino acids are the building blocks of proteins that our bodies need to survive and thrive. Our body can manufacture many amino acids from the basic ingredients of our food (fuel). There are some, however, that must be obtained from outside food sources. These are referred to as essential amino acids. It’s essential we get them from our food. The quality of the manufactured food we eat today is so lacking in real nutrition, it’s nice to know we can get a supplement to fill the gap. When would you want to take a supplemental amino acid? Many people know that L-Lysine will stop a herpes cold sore. It also stimulates our immune system. I give L-Lysine to Spot, a cat that seems to have chronic eye infections. It usually clears the infection in one day. The amino acid GABA acts much like the tranquilizer valium and is not habit forming. When you study the amino acids, you realize how vital they are to our health.We list the individual aminos on this site but if you want a combination of all 8, this product is for you.
