NAC formula is a dietary supplement designed to strengthen the immune system and protect the respiratory tract. Its main component, N-Acetylcysteine, is a powerful antioxidant that acts as a precursor to glutathione, aiding in liver detoxification and bolstering the body's defenses. This formula combines N-Acetylcysteine (290 mg) with quercetin, a natural flavonoid with antioxidant and anti-inflammatory properties, supporting the immune system and protecting against oxidative stress. Additionally, it contains zinc and selenium, essential minerals for proper immune function and overall health. The combination of these ingredients helps keep airways clear and prevent irritation, providing effective relief in cases of respiratory congestion. This supplement is ideal for those looking for extra support in respiratory and general health, especially during seasonal changes. Its presentation in vegetable capsules ensures optimal absorption and high digestive tolerance.
