Description

N-Acetyl Cysteine, commonly known as NAC, is a stable supplemental form of cysteine, an amino acid the body uses to produce glutathione — one of its most important endogenous antioxidants. By supporting healthy glutathione levels, NAC helps support antioxidant defense, respiratory wellness, immune function, and natural detoxification pathways.

Frequently Asked Questions

Is Double Wood NAC hypoallergenic?

Double Wood NAC is made without soy, gluten, GMOs, dairy, eggs, fish, shellfish, tree nuts, peanuts, wheat, or sesame. It is also vegan, making it a good fit for many customers with restricted diets or ingredient sensitivities. Always review the full label if you have a severe allergy.

What is NAC used for?

N-acetylcysteine (NAC) is primarily used to boost glutathione levels, a critical antioxidant that protects cells from oxidative stress and supports liver detoxification. Additionally, it can help thin mucus and reduce inflammation, making it beneficial for respiratory health.

What’s in Double Wood NAC besides NAC?

Double Wood NAC contains N-Acetyl Cysteine plus three simple other ingredients: hypromellose capsule, rice flour, and microcrystalline cellulose. The formula is intentionally minimal and does not include unnecessary artificial colors, flavors, or common major allergens.

How much NAC per day?

N-acetylcysteine (NAC) is typically taken in daily doses ranging from 600 mg to 1800 mg, often divided into two or three doses throughout the day.

How long does it take for NAC to work?

NAC is rapidly absorbed, so for acute issues like respiratory symptoms, some benefits may be observed within a few hours to days. However, for long-term benefits such as enhanced antioxidant protection and improved liver function, consistent use over several weeks is generally needed, with results varying by individual.
