Quality of Life Labs Advasorb Vitamin C, 60Vcaps


Whether you are taking vitamin C for antioxidant protection, detoxification, or immune support, amplify its effects with Advasorb® Vitamin C.

Combining Fast-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 Fast-C? It delivers 54% more vitamin C into the tissues in the first 2 hours vs. the leading premium brand.

It's buffered — No upset stomach and no heartburn.

Vitamin C (Fast-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.* Fast-C™ is a buffered, rapidly absorbed, better-retained form of vitamin C than regular ascorbic acid.

Vitamin C & Fast-C Clinical Evidence

Fast C Bioavailability

Presented at Experimental Biology
Labiste K et al. A Clinical Evaluation Comparing the Bioavailability of Two Buffered Vitamin C Supplements in Healthy, Non-smoking Males. Apr. 2008. 

Topic: 
How does the bioavailability of Fast C compare to that of Ester C?

Background:
Ester C has become the leading premium brand of vitamin C, due to the fact that it has been marketed as being better absorbed than regular ascorbic acid. It is also buffered, making it easier on the stomach. How does Fast C, a new form of buffered Vitamin C, compare to Ester C?

Study Type:Human clinical intervention trial

Study Design:
Subjects ate a diet low in vitamin C for at least one week and then took a dose of either Fast C or Ester C, followed by another week of the low Vitamin C diet and then a dose of the other brand of vitamin C. (The order of the brands was randomly assigned.) Blood was drawn pre-dosing and at 30, 60, 90, 120, 210, and 240 minutes after ingesting the supplement. Urine was also collected for 24 hours after taking the supplement.

Subjects:
5 healthy, non-smoking, young males

Dosage:
Single, 1-gram dose

Results:
Weight-adjusted concentrations of ascorbic acid in the subjects’ blood were significantly higher for Fast C than for Ester C at 60 minutes, although peak levels did not show significant difference. Fast C delivered 54% more vitamin C into the tissues in the first 2 hours than Ester C. Urinary levels of vitamin C were similar for the two brands.

Conclusion:
[T]here were no differences in the overall absorption between the AA [ascorbic acid] products over the 4-hour test period, with [Fast C] displaying a faster rate of absorption than Ester C.


NAC Clinical Evidence

NAC and Oxidative Status

Urology
Ciftci H, et al. Effects of N-acetylcysteine on semen parameters and oxidative/antioxidant status. 2009 Jul;74(1):73-6. 

Topic: 
Can N-acetylcysteine (NAC) improve oxidative/antioxidant status and semen parameters in infertile men?

Background:
Free radicals can harm sperm, and may play a role in male infertility. Can NAC, an antioxidant, improve the antioxidant status of infertile men?

Study Type:
Human clinical intervention trial

Study Design:
Placebo-controlled. Subjects took NAC or placebo. Blood and sperm samples were taken to asses the subjects’ oxidative status and sperm parameters.

Subjects:
120 infertile adult men

Dosage:
600 mg/day for 3 months or placebo

Results:
After treatment, the total antioxidant capacity was greater and the oxidative stress index was lower in men who had taken NAC. In addition, their semen quality improved.

Conclusion:
We believe that NAC could improve some semen parameters and the oxidative/antioxidant status in patients with male infertility.

 
 
 

N-acetyl-L-Cysteine

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.*
