Fast-Acting Colon SupportDietary SupplementOccasional constipation is one of the most frequent gastrointestinal complaints in the United States, particularly among women and the elderly. To address this issue, Life Extension offers a dose-adjustable nutritional solution�Effervescent Vitamin C - Magnesium Crystals�to provide immediate relief from occasional constipation.A series of rhythmic muscle contractions move food through the digestive tract. But highly processed foods and a lack of quality nutrition can occasionally result in normal but temporarily ineffective movement of waste through the colon.Vitamin C is an antioxidant that scavenges free radicals in the body and protects tissues from oxidative stress. Vitamin C is a vital cofactor for the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth.Magnesium is a cofactor in hundreds of enzymatic processes within cells, helps maintain healthy blood pressure levels already within normal range, improves the metabolic profile, and beneficially impacts insulin resistance and inflammation. Research shows many Americans do not obtain adequate magnesium in their diets.Effervescent Vitamin C - Magnesium Crystals can be used in varying doses depending on individual need. It contains no harsh chemicals and is safe for up to three times per week, since it contains only nutrients that provide other benefits. Effervescent Vitamin C - Magnesium Crystals is not a fiber�so it never creates more fecal bulk than you can easily evacuate.
