Whether you are taking vitamin C for antioxidant protection, detoxification, or immune support, amplify its effects with Advasorb® Vitamin C. Combining PureWay-C®, a unique, rapidly absorbed, and better retained form of vitamin C with N-acetyl cysteine (NAC), this potent formula delivers:

  • Antioxidant Protection — Vitamin C and NAC are both antioxidants that neutralize harmful free radicals.*
  • Detoxification Support —  Animal and human studies have demonstrated that both vitamin C and NAC help the body detoxify a range of pollutants, including heavy metals, automobile exhaust, tobacco smoke, industrial chemicals, and pesticides.*
  • Immune Support —  Human clinical trials have shown that daily intake of vitamin C during the cold-weather season can promote immune response.* A placebo-controlled study also found that people who took NAC in the winter maintained their well-being.*

Why PureWay-C®? Research conducted at the University of Miami School of Medicine found that a single oral dose of PureWay-C® raised blood levels of vitamin C higher for a full 24 hours compared to other forms of vitamins.

Vitamin C (PureWay-C®)

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin, meaning it dissolves in water rather than fat. Because water-soluble vitamins are not stored in the body, they need to be replaced daily. Vitamin C contributes to the health of the body by increasing its antioxidant, immune-stimulating, and detoxification powers.* PureWay-C® is a buffered, rapidly absorbed, better-retained form of vitamin C than regular ascorbic acid.

Black Pepper extract

Black Pepper extract (BioPerine®) is a patented black pepper extract-based product containing an ability to increase the bioavailability of nutritional compounds. To help amplify positive effects on your health, you need to take this supplement in conjunction with other health supplements.


 N-acetyl-L-Cysteine (NAC) is a combination of the amino acid L-cysteine plus an acetyl group, which speeds absorption and increases bioavailability compared to regular cysteine. Best-known for its detoxifying capacity, NAC can bind with various toxins, such as mercury and lead, helping remove them from the body.* NAC additionally has been shown to increase the antioxidant capacity of the blood in humans and help maintain a robust immune system during the winter months.*


Q: How does Advasorb™ Vitamin C compare with regular vitamin C (ascorbic acid)?

A: Most vitamin C products on the market are formulated with ascorbic acid. As the name implies, ascorbic acid is acidic – which means it can cause an upset stomach and heartburn in some individuals. , featured in Advasord™C, is buffered with a blend of alkalizing minerals, so it does not cause gastrointestinal distress. You can even take it on an empty stomach!

Advasorb Vitamin C

Oh gosh, I was crazy when this went out of stock! Thank you for bringing it back. I told my Chiropractor, Barry Sunshine, just last week, that I feel a definite different in taking this Vitamin C over other brands. I love all of the products I receive from Quality of Life and I find them to be reasonably priced as well. Thank you for doing such a great job in a huge market!
