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. In addition, NAC can help to support healthy brain and neuronal tissues. Natural color variation may occur in this product.

NAC 1000 mg size
These tablets are way too large to comfortably swallow, especially for seniors. Have had 1000 mg in past, but was surprised to receive tablets vs gel caps. Need to inform consumers what form they are getting, so they can decide to purchase or not. If this is NOW's new trend with this dose of NAC, I need to look elsewhere.

Unpleasant odor worse than others I've had before
I know it's not uncommon for NAC to have an unpleasant odor or taste, but these are worse than I've had before. I bought another brand with similar reputation for quality and they were less unpleasant and tolerable. I don't know if these were stale or not sealed well but neither my wife nor I could take them.
