N-Acetyl Cysteine (NAC) is an amino acid that promotes synthesis of proteins and creates the potent antioxidant enzyme glutathione. It works to:
What is N-Acetyl Cysteine?
N-Acetyl Cysteine (NAC) is a free-form amino acid that supports important biological pathways for overall health and well-being. It contributes the body’s cellular defenses by helping to synthesize glutathione. Also known as GSH, glutathione is an efficient water-soluble antioxidant that helps to neutralize the age-accelerating, cell-damaging effects of a wide range of destructive free radicals, especially within muscle tissue. This muscle-protective property, combined with NAC’s ability to promote protein synthesis, have made the supplement popular among athletes and bodybuilders. However, its antioxidant-related biological activities may support healthy aging in all populations.**
NAC promotes cardiovascular wellness. Specifically, the compound has been found to modulate homocysteine synthesis while helping to flush existing homocysteine out of the body. Homocysteine is an amino acid that, when elevated in the blood, is a risk factor for cardiovascular issues including hardened arteries and circulation problems. As it influences homocysteine, N-Acetyl Cysteine may encourage blood vessel flexibility and circulatory wellness, supporting important components of cardiovascular health.**
This amino acid compound has also been linked to lung health and clear breathing, and is believed to help with multiple respiratory issues related to congestion, inflammation and upper respiratory problems. Additional research suggests potential roles in supporting immune system health and optimal liver cleansing capacity.**
N-Acetyl Cysteine Supplements
N-Acetyl Cysteine supplements are typically presented as capsules, coated caplets or tablets.
N-Acetyl Cysteine Directions for Use
There is no set dosage, but the nutrient is often recommended at 250 mg to 1000 mg per serving. Consult with your doctor before adding this supplement, or any other supplements, to your healthy lifestyle regimen.**
