Side effects of Glutamax capsules? Does it really help lighten the overall skin tone?

Thank you for your question! Glutathione is a well known antioxidant in the body .This is also  widely used in asian countries for skin lightening. Glutathione oral products are not well absorbed from the intestine and had to be metabolized to to another molecule before this is taken up by the body cells. Glutathione can be absorbed intact into the blood stream when administered in IV form as a nutritional supplement . Certain oral glutathione precursors like N Acetylcysteine, R-Alpha Lipoic Acid, Selenium and Silymarin can be taken to increase the body's supply of glutathione.  Glutathione  inhibits tyrosinase enzyme which then switches the production of eumelanin to phaeomelanin.  Its lightening effects appear to work better when combined with IV vitamin C. IV glutathione when combined with IV vitamin C helps  to stay  in its most active form.  Glutathione also appears to work  by eliminating the body of free radicals or toxins that lead to hyperpigmentation, age spots, sun spots, wrinkles and conditions such as melasma. Vitamin C has been scientifically proven to raise the levels of glutathione in the body. The potential side effects of the IV injection include anaphylaxis, nausea, phlebitis and abnormal liver test. Certain oral preparations may help increase the Glutathione body storage hence be effective not only as antioxidants but skin lightening. Best of luck!
