What is N-Acetyl L-Cysteine?

Supplementing with regular L-Cysteine is useless; it is used far too rapidly by the body to ellicit any positive benefits. In contrast, N-Acetyl L-Cysteine is a much more stable form of L-Cysteine and can be used to great effect. It is a powerful antioxidant but has a variety of other functions ranging from liver support to anti-aging.

Where to find N-Acetyl L-Cysteine

L-Cysteine is produced naturally in the body. It is also found in foods such as chicken, oats, egg yolks, broccoli, onion, sprouts, garlic and red peppers. Remember L-Cysteine is extremely unstable and is therefore practically worthless. N-Acetyl L-Cysteine can only be obtained through supplementation.

N-Acetyl L-Cysteine can also be referred to as:

NAC, N-Acetylcysteine, N-Acetyl Cysteine, Acetyl-Cysteine, Cysteine, L-Cysteine.
