NAC has been around for a long time and is one of the most researched amino acid derivatives, so it’s no surprise you’ll find it in your local health store. NAC however is easily oxidized when exposed to air and an open bottle of capsules is very vulnerable to oxidation. PharmaNAC individually wraps each tablet in 4-layer vacuum seal to protect each NAC table from degradation and oxidation. PharmaNAC also delivers 900mg per tablet as compared to 600mg capsules and is available in an effervescent form providing an alternative for those who have difficulty swallowing capsules. In a study done in the European journal of Clinical Pharmacology it was found that oral does of fast dissolving tablets had a higher bioavailability than slow release tablets [3]. Solid capsules or tablets are dissolved gradually in the stomach and depending on the individual physiological factors capsules may not fully dissolve and cause irritation on the mucous membrane of the stomach. Effervescent tablets allow for an even distribution of NAC concentration and create a balanced buffered solution for easy absorption. NAC powder has a very unpleasant taste due to the sulfur found in cysteine and most are not able to tolerate the awful taste. PharmaNAC flavors NAC with a great Wildberry taste, providing you with an enjoyable fizzy drink.References:1. Bonanomi L, Gazzaniga A.
