Frequently Asked Questions

Everything you need to know about this product.

What is Nature's Sunshine N-Acetyl Cysteine?

N-Acetyl Cysteine (NAC) is a potent antioxidant supplement that provides 300 mg of NAC per tablet along with turmeric. It serves as a precursor to one of the body's strongest natural antioxidants and supports the liver, cardiovascular system, skin, and eyes.

What are the key ingredients and what do they do?

Each tablet contains 300 mg of N-acetyl cysteine, which helps enhance the body's natural antioxidant defenses and provides a line of defense against free radicals and environmental toxins. It also includes turmeric, which is known for its liver-supporting properties.

How do I take N-Acetyl Cysteine?

Take 1 tablet with a meal twice daily. Each bottle contains 60 tablets, providing a 30-day supply at the recommended serving.

Who is this product best suited for?

This product is a great fit for adults looking to support their liver, cardiovascular health, skin, or eyes, as well as those seeking enhanced antioxidant protection against free radicals and environmental toxins. As with any supplement, anyone who is pregnant, nursing, or on medication should consult their healthcare provider before use.

How does N-Acetyl Cysteine compare to other antioxidant and detox products?

NAC focuses specifically on boosting the body's own antioxidant production while supporting the liver and cardiovascular system. If you're looking for more targeted liver support, Milk Thistle Combination is another option, while Alpha Lipoic Acid offers a different type of antioxidant support. For a broader cleansing approach, Heavy Metal Detox, Detox Basics, or Super Trio may be worth exploring depending on your wellness goals.

    N-Acetyl Cysteine (300 mg)

    I have been taking N-Acetyl Cysteine (300 mg) for 2 years as recommended by my lung specialist. It has really made a difference in my life allowing me to participate in more activities with my children and grandchildren. I have COPD and if I miss taking the NAC I can really tell a difference and I have more difficult breathing. N-Acetyl Cysteine (300 mg) is a great product!
