Wow, this topic has been discussed for years and still going, yes they do work. Actually Glutathione is the Ultimate anti-oxidant, anti-aging and Immune Booster which carries a side effect of skin lightening when taken in a proper dosage. All ingredients are water soluble and liver and kidney friendly so no worries on overdosing as it will just exit our system through urine and bile.
BUT you have to be smart and wise enough to purchase your Glutathione from trusted sellers (not from the Philipines; bad experience, lots of fake!). If there is a fake version of it, please do not buy, only USA made and the trustworthy ones, but if the order is coming from places beside USA, beware because you are not protected in any way.
I only found 3 brands that are actually Made and Manufactured in the USA, ), Puritan Sale (250mg Glutathione) and Prism medical, Gluta-C (500mg, 100mg Vit C, 100mg ALA) there are also Glutathione in GNC but it's only 200mg Glutathione, not enough for skin lightening but a good anti-oxidant supplement AND they are not blended with other anti-oxidant and amino acid..
They are safe. You are taking vitamins I assume, well its the same as taking Vitamins because Glutathione is a Dietary Supplement. It will all depend on where you're buying it from, Goodluck!
ANyone try this and does it work?
