About Nature’s Sunshine N-Acetyl Cysteine
Your body faces constant exposure to environmental stressors, pollutants, and free radicals that can challenge your cellular health. Nature’s Sunshine N-Acetyl Cysteine provides targeted antioxidant support by delivering a highly bioavailable form of this important amino acid derivative. Each tablet contains 300 mg of N-Acetyl Cysteine (NAC), enhanced with turmeric root for comprehensive cellular protection.
N-Acetyl Cysteine is the acetylated form of the amino acid L-cysteine, making it more stable and easily absorbed than regular cysteine. Once consumed, NAC is converted into cysteine in your body, which then serves as a building block for glutathione production. Glutathione is often called the “master antioxidant” because of its crucial role in protecting cells from oxidative damage and supporting the body’s natural detoxification processes.
The Power of Glutathione Support
What makes NAC particularly valuable is its role as a glutathione precursor. Glutathione is naturally produced by your liver and is essential for neutralizing harmful free radicals, supporting immune function, and helping your body eliminate toxins. However, glutathione levels can become depleted due to age, stress, poor nutrition, environmental toxins, and various health challenges.
NAC provides your body with the raw materials needed to replenish glutathione levels naturally. This indirect approach to antioxidant support is often more effective than taking glutathione directly, as NAC is better absorbed and more stable in supplement form. By supporting healthy glutathione levels, NAC helps maintain your body’s natural defense systems.
Enhanced with Traditional Turmeric
Nature’s Sunshine has enhanced this formula with turmeric root, a time-honored botanical known for its antioxidant properties. Turmeric contains naturally occurring compounds called curcuminoids, which complement NAC’s antioxidant activity. This combination provides dual-pathway support for your body’s antioxidant systems and traditional wellness benefits.
The inclusion of turmeric also reflects Nature’s Sunshine’s commitment to combining modern nutritional science with traditional herbal wisdom. This thoughtful formulation approach ensures you receive comprehensive support for your cellular health and overall wellness goals.

Each tablet of Nature’s Sunshine N-Acetyl Cysteine is manufactured to strict quality standards, ensuring consistent potency and purity. The convenient twice-daily dosing makes it easy to incorporate into your daily wellness routine, whether you’re looking to support your body’s natural detoxification processes or maintain healthy antioxidant levels.

Frequently Asked Questions
N-Acetyl Cysteine (NAC) is the acetylated form of the amino acid L-cysteine, which makes it more stable and bioavailable than regular cysteine. In your body, NAC is converted to cysteine, which then serves as a building block for glutathione production. Glutathione is one of your body’s most important antioxidants, helping to neutralize free radicals and support detoxification processes.
NAC is often more effective than taking glutathione supplements directly because it’s better absorbed by the digestive system and more stable in supplement form. Glutathione can be broken down by stomach acid and digestive enzymes before it reaches your cells, while NAC survives the digestive process and provides your body with the raw materials to produce glutathione naturally.
Turmeric root has been added to complement NAC’s antioxidant activity. Turmeric contains naturally occurring curcuminoids that provide additional antioxidant benefits and have been traditionally used to support overall wellness. This combination offers dual-pathway antioxidant support for comprehensive cellular protection.
Take 1 tablet twice daily with meals to optimize absorption and minimize any potential stomach upset. Do not exceed the recommended dose.
