Glutathione is a a tripeptide consisting of glutamic acid, cysteine and glycine is known to act as coenzyme in a few enzymatic reactions, but its importance may lie in its role as a non specific reducing agent within the cell. Glutathione is the most abundant non-protein compound present in living organisms. Glutathione has many functions beyond removal of toxic metals like mercury. It is essential for maintaining cellular redox state, which every human metabolic process depends upon, in every living cell in our bodies. Glutathione peroxidase may help delay the physical effects and problems of aging. Adequate amounts of glutathione are needed to help the immune system fight against free-radical damage, infection, and illness. may help prevent or lessen symptoms of conditions like asthma and rheumatoid arthritis. There's NO NEED to take additional Vitamin C, Vitamin E, Grapeseed, Alpha Lipoic Acid, zinc or other ingredients for effectiveness esp. if the Glutathione is already pre-mixed with these said ingredients. Research shows it has minimal absorption through the gut especially for the purpose of skin lightening, taking this extra supplement is not required. But if you think it will accelarate the skin lightening effects, then for arguments' sake, take them. But I suggest to talk to your Medical Practitioner for proper dosage before going too extreme with your dosage.
Skin lightening from taking L-Glutathione is just a side effect, this is not the main purpose of Glutathione. Glutathione is the Ultimate anti-oxidant, anti-aging, Immune Enhancement and detoxifier, skin lightening is just a BONUS! Make sure to ONLY get pure 100% reduced L-Glutathione. Oxidized, unreduced or blends will not work for any purpose. And for obvious reasons, stay out of the sun and wear SPF 30 or more, otherwise you will just defeat the purpose. 500mg twice a day is enough dosage (Glutathione) as a dietary supplement or skin whitening. If anyone recommends more is obviously wanting to earn more. L-Glutathione is good for you. There has been no known bad side effects from taking glutathione. You will receive the benefits of Immune enhancement, detoxification and Anti-oxidant with use of this product. Skin whitening is just a Bonus!
For skin lightening, wait an average of 45-60 days of regular use before expecting results, remember Glutathione works by interfering melanin production pathways, therefore overnight results are unrealistic. Roughly 3-5% of users will not see this results for such unknown reason(s). If you haven't seen or achieved results after 3 months (for brown skin) or 4 months (for dark skin), please do not waste your money as you may be one of the few who are not responding as expected from Glutathione intake, BUT please free to continue it as a dietary supplement for good health and well being
Due to the nature of this business (ONLINE), it is pretty hard to tell just by looking at the website which one is a legit vendor or just a fly by night. Fakes and adulterated L-Glutathione is rampant. Please use your best judgement and don't be ashamed to ask questions.
Goodluck and may you be on your path to a Healthier and Fairer you.....
