## Description

1,000 mg NAC, 500 mg Quercetin & 15 mg Zinc per serving N-acetyl cysteine (NAC) is a stable form of the non-essential amino acid cysteine. It is a sulfur-containing amino acid that acts as a stabilizer for the formation of protein structures, and promotes the formation of glutathione.* Glutathione is a powerful free radical scavenging compound that also helps to maintain normal, balanced immune system function.* Quercetin is a naturally occurring free radical neutralizer that supports healthy seasonal immune system function.* Laboratory studies have demonstrated that quercetin can also help to promote normal respiratory function.* Zinc has been included for its immune-supporting properties.* Natural color variation may occur in this product.

Review: Great supplement - This supplement was what was missing to complement my health care. In a few days of use, I already feel the beneficial effects.
Review: Potassium Chloride substitute for table salt - Helps greatly in cutting back on sodium intake. It can have a little bitter taste if used excessively. I often use a salt shaker mixture of 3 parts potassium chloride to 1 part table salt, or half an half. Either potassium chloride or table salt will have a bitter taste if used in excessive, just a different bitterness. Good alternative to table salt.
