"The building blocks of Glutathione"
Glutathione precursors are the nutritional building blocks your body uses to make glutathione.
Taking straight glutathione supplements is a waste as the glutathione is destroyed by the acids in the stomach.
This is one of the reasons why it is best to take the building blocks of glutathione, known as precursors of glutathione.
Remember, glutathione is an endogenous antioxidant, meaning it is made by the body. So, taking glutathione is ineffective. Instead, you can take GSH precursors, which your body will then use to make glutathione.
There are three main precursors of glutathione:
-Glutamic Acid (glutamate)
Glutamic Acid and Glycine are abundantly made in the body and easily found in the foods we eat.
Cysteine is also made in the body but requires methionine (a cysteine precursor). Methionine is often used up for other bodily functions (like eliminating fat--VERY important! and creating creatine to feed our msucles)
So if the methionine is used up, not much is left for cysteine production. So what's the solution? Find out here: L-Cysteine
