How can we distinguish between FAKE and GENUINE Oral Glutathione supplements?
The TASTE Glutathione reduced is a tri-peptide thiol composed the amino acids l-cysteine, glutamic acid and glycine while KB Gluta plus NAC is a FREE FORM (single bond) which also composed the three amino acid. . According to certified oral glutathione manufacturers, genuine l-glutathione has a very tangy sour taste. The SMELL KB Gluta (free form) + NAC is a biologically active sulfur and therefore, will have a slight sulfuric smell (frequently compared to rotten eggs). Sulfur is the reason glutathione is so good at binding toxins. In order to minimize the sulfur smell, each bottle of Kyusoku Bihaku with NAC contains a dessicant. Furthermore, NAC is yet another amino acid with l-cysteine, which is also the active component of glutathione. This even adds to the slightly unpleasant smell emanating from KB sets/bottles.
