Product Overview

Description
  • Patented Formula!
  • Bilayer Tablets
  • Quick + Sustained Releases
  • Antioxidant and Glutathione Precursor
  • Supports Liver and Lung Function
  • Gluten Free
  • Dietary Supplement
  • Bilayer - Sustained - Quick

NAC SustainĀ is in a special Sustain bilayer Quick Release/Sustained Release format of N-Acetyl-L-Cysteine (NAC), a powerful antioxidant amino acid and a precursor to the critical antioxidant glutathione. Glutathione exerts a variety of protective effects, including detoxification and intracellular defense against oxidative stress. Substances known to reduce glutathione status are acetaminophen and alcohol.

The advanced bilayer Sustain tablets combine 1/3 Quick Release and 2/3 Sustained Release formats to both immediately raise and to maintain blood levels over a longer period of time. NAC Sustain releases in the small intestine over a 8 hour period, compared to the 1.5 hour biological half-life of NAC in the bloodstream.

Suggested Use

Take 1 tablet 1 to 2 times per day, preferably on an empty stomach with fruit juice, or as directed by your qualified healthcare professional.

Other Ingredients

Carbomer, calcium phosphate, cellulose, stearic acid (vegetable source), magnesium stearate (vegetable source), silicon dioxide, beet root powder (for color) and an aqueous-based coating.

No wheat, no gluten, no soybeans, no dairy, no egg, no fish/shellfish, no peanuts/tree nuts.

Warnings

Note: Prolonged or elevated intake may alter liver function tests without affecting actual liver function. Inform your physician that you are ingesting NAC if you undergo liver function tests.

Keep out of the reach of children.

LOVE THIS PRODUCT, BUT BE CAREFUL OF HIGH BLOOD PRESSURE!
I love this product and initially felt really good taking it the first week. I've been taking this for 2 weeks. Began using this to detox from removal of amalgam (mercury/silver) dental fillings. Without knowing the cause, I started to feel anxious, constricted...like I had too many things going on at once. I then had a dental appt. and they took my blood pressure before placing a crown. They said my blood pressure is high, which they thought would be nervousness sitting in a dental chair. Never had high blood pressure before...am 40 yrs and healthy. I later found on the Internet that research from the University of Virginia Health System has found that NAC can cause the body to believe that it is experiencing hypoxia by forming a molecule that causes the signals the blood vessels they are low on oxygen. The body responds by increasing pulmonary blood pressure, which then causes the heart to swell. Due to the possible effects on blood pressure, patients managing their blood pressure should consult with their physician before taking N-Acetyl-L-Cysteine. I have now switched to L-Glutathione to detox from mercury and other toxins.

Alcohol Poisoning Detox
Another little know benefit of Cysteine in its various forms such as N-Acetyl Cysteine is its ability to help detoxify the liver in the case of alcohol poisoning, more commonly known as a hangover. People tend to take a NSAID (nonsterodial, anti-inflammatory drugs) like aspirin or ibuprofen after heavy drinking and before bed, it is better to take L-Cysteine, or N-A-C, so as not to add insult to injury of the liver and digestive tract.
