Most cells are not able to take up intact glutathione and therefore rely on the uptake of its precursors including cysteine, to produce glutathione. Glutathione is considered to be the 'master antioxidant' and is vital for a plethora of biochemical functions and reactions in the body. Genetic individuality can affect the body's own production of glutathione making supplementation with its precursor such as cysteine more necessary. This product is suitable for those experiencing conditions where low levels of glutathione may occur, such as issues with the transsulphuration pathway. Cysteine is also a methyl donor in many biochemical pathways including the conversion of homocysteine to methionine and the inhibition of pro-inflammatory cytokines such as TNF. The bodyÔÇÖs own supply of cysteine can be low due to a number of factors such as poor absorption or low intake of dietary sources from vegan or vegetarian diets for example.
