Be Wary Of Glutathione Product Claims!

Some search terms matched

Many skincare and supplement companies throw around the word “glutathione,” but most of their products don’t actually deliver meaningful amounts—or the right form. For example, a popular serum claims anywhere from 50,000 ppm to just 500 ppm glutathione, which would equal almost nothing per bottle. On top of that, most products use oxidized glutathione, which doesn’t work in the body. That’s what makes VARS Glutathione different—it stays in its reduced, functional form all the way until your cells use it, giving you a real therapeutic dose that actually works.
