N-Acetyl L-Cysteine (NAC) is a powerful antioxidant that plays a key role in promoting overall wellness. NAC is a derivative of the amino acid cysteine and is well-known for its ability to replenish glutathione levels in the body. Glutathione is crucial for detoxification, immune support, and oxidative stress reduction.

As a trusted contract supplement manufacturer, OriginBio provides premium NAC capsules that help improve liver function, lung health, and cognitive function.

What Are the Key Ingredients in NAC Capsules from OriginBio?

The primary ingredient in our NAC capsules is N-Acetyl L-Cysteine, a stable form of cysteine that is more bioavailable and effective than regular cysteine. Additionally, OriginBio ensures the inclusion of excipients that aid in capsule stability and absorption, such as:

Vegetarian Capsules: We offer plant-based capsules for those seeking vegan-friendly supplements.
No Artificial Fillers: Our NAC capsules contain no artificial colors, flavors, or preservatives.

What Is the Recommended Dosage for NAC Capsules?

NAC is an acetylated derivative of the amino acid L-cysteine; it acts as a precursor to glutathione and has mucolytic and antioxidant properties. Capsules are popular because NAC is stable in dry powder form, capsules allow precise dosing (typical OTC doses 600–1,200 mg), and capsules protect powder from moisture and oxygen—key for shelf life.
