NOW NAC Quercetin & Zinc is a three-in-one antioxidant supplement designed to support balanced immune function and normal respiratory wellness. Each two-capsule serving provides 1,000 mg of N-acetyl cysteine, 500 mg of quercetin, and 15 mg of elemental zinc from zinc bisglycinate.

N-acetyl cysteine, commonly known as NAC, is a stable form of the amino acid cysteine. It supports the production of glutathione, an important antioxidant compound that helps neutralize free radicals and maintain normal immune system function. Quercetin is a naturally occurring plant flavonoid that provides additional antioxidant support while promoting seasonal immune balance and normal respiratory function. Zinc completes the formula by supporting everyday immune health and normal cellular processes.

This thoughtfully combined NAC, quercetin, and zinc supplement is suitable for adults seeking convenient antioxidant, immune, and respiratory support in one daily formula. The non-GMO vegetable capsules are dairy-free, egg-free, soy-free, nut-free, and made without gluten. Each bottle contains 90 veg capsules, providing 45 daily servings when used according to the label directions.
