Key Benefits
NOW Foods' NAC supplement combines NAC with selenium to enhance antioxidant defence, detoxification, immune support, cardiovascular health, and respiratory function.
N-Acetyl Cysteine (NAC) is a form of cysteine which is a conditionally essential amino acid and carries an array of benefits to our bodies. This amino acid is essential for producing the powerful antioxidant glutathione, which is one of the body's most important antioxidant due to its compounds that neutralises free radicals which damage our cells and its natural detoxifying properties.
NAC has been considered so powerful for our detoxification process that doctors commonly use it intravenous to protect the liver and kidney during an acetaminophen overdose in order to prevent damage on these key organs. This gives you an idea of how effective NAC is, however, when ingested through supplementation the dose will inevitably be smaller but still effective enough to boost our natural detoxification function against environmental and daily toxins, increase brain health, improve respiratory and immune system, and to decrease inflammation in lipid tissues which could trigger a reduction to insulin resistance.
NOW Foods is a family owned company since its start in 1968, and has relentlessly been making the natural supplement and products industry better since. Its mission has always been and is to provide value in their products which empower people to lead healthier lives all around.
