News report on sub-standard and fake glutathione in the Philippine market. According to some dermatologists, instead of putting glutathione in the capsules, some repackers may be putting N-acetyl-cysteine (NAC) which boosts glutathione production in the body and considered to be more effective than taking glutathione itself. But glutathione is better known as a skin whitener than NAC. However, NAC is much cheaper than glutathione, the reason why deceptive repackers "substitute" the ingredients & mislabel their NAC capsules as 'glutathione'. Some repackers also use a cheap blend of the 3 amino acids that make up glutathione. To play it safe, it is advisable to use only unrepacked, reputable brands of glutathione from the USA and Japan.
