NAC is another way of boosting glutathione but there are a few drawbacks and an important caution.

NAC is the supplemental form of L-cysteine, a semi-essential amino acid present in our bodies. L-cysteine is the amino acid that helps make up the glutathione tri-peptide molecule (glutathione).

The difference between NAC and MaxOne is that with MaxOne, the l-cysteine is bonded to D-Ribose (a natural sugar) that gets into the cellular structure. The unbonded l-cysteine in NAC acts differently.

Where the percentage boost of glutathoine from MaxOne is known as approx 270% from 2 caps daily, the percentage boost from L-cysteine (NAC) is not as predictable.

With MaxOne, you can take up to 8 or 10 caps daily with no side effects or issues. With NAC, a maximum of 3 per day are recommended.

Caution: While its always recommended for everyone to drink 6 - 8 glasses of water a day. If you fall short with MaxOne, there's no issue. However, if you do not drink those 6 - 8 glasses a day of water, with NAC kidney stones may form - not a pleasant experience.
