What is Calcium Ascorbate Buffered Vitamin C?
Calcium ascorbate is a buffered form of Vitamin C (Ascorbic Acid). It is used as a nutritional supplement and food additive and is gentler for people with sensitive gastrointestinal tracts. To produce this product, calcium is reacted with ascorbic acid, decreasing the acidic nature of this vitamin substantially.
Combining calcium and ascorbic acid delivers the vital benefits of both supplements.
Calcium ascorbate couples ascorbic acid (Vitamin C) with calcium carbonate. As the calcium salt of ascorbic acid, calcium ascorbate is hydrolyzed in the stomach, yielding calcium and an ascorbate ion. Stomach acid changes the ascorbate ion to ascorbic acid with no net increase in stomach acid levels.
Ascorbic acid facilitates calcium absorption, making it more bioavailable to the cells.
Ascorbic acid is important in many other critical functions such as the absorption of iron, stimulation of immune system and as an antioxidant to strengthen the immune system.
Vitamin C as an Antioxidant - Vitamin C is one of many antioxidants that block damage caused by free radicals, byproducts of our bodies transforming food into energy. Vitamin C neutralizes potentially harmful reactions in the watery parts of the body, such as blood and fluid both inside and surrounding cells.
Vitamin C and Connective Tissue - As a participant in hydroxylation of proline, vitamin C is needed for the production of collagen, a protein substance which all fibrous tissue integrity depends on. These fibers are found throughout the body, providing firm but flexible structure. Collagen is the "glue" that strengthens many parts of the body like the muscles and blood vessels. It is needed to develop and maintain healthy teeth, bones, gums, cartilage, vertebrae discs, joint linings, skin and blood vessels. By supporting collagen production, vitamin C is essential for the healing of wounds and for the repair of these tissues.
Vitamin C and Immune System - Vitamin C may be useful as an immune stimulator and modulator in some circumstances. Vitamin C promotes resistance to infection through the immunologic activity of leukocytes, the production of interferon, and maintaining mucous membranes.
Humans have only three of the four enzymes necessary for internal production of ascorbic acid and must satisfy the need for the vitamin through eating vitamin C-rich foods or nutritional supplementation.
Purity and Concentration of Calcium Ascorbate Buffered Vitamin C
This Purebulk product contains no fillers, additives or anti-caking agents. Each molecule of calcium ascorbate buffered vitamin C yields 90% actual vitamin C and 10% calcium.
Potential Side Effects of Calcium Ascorbate Buffered Vitamin C
Calcium ascorbate is generally nontoxic and side effects rarely occur. High amounts (more than 2,000 milligrams daily) of vitamin C may cause diarrhea, gas, or stomach upset. Any side effects from supplementation generally are reduced or disappear with a decrease in use.
High intake of ascorbic acid may reduce copper levels in the body. This could be a problem for individuals with an existing copper deficiency or marginal copper stores. People with iron storage diseases such as hemochromatosis should consult a physician before taking vitamin C supplements since vitamin C increases iron absorption. Pregnant women should consult their prenatal care professional when using vitamin C supplements since infants born to mothers taking high amounts of vitamin C could develop rebound scurvy (ascorbic acid deficiency disease) due to a sudden drop in vitamin C levels after birth. This is generally only seen when the mother has been consuming more than 6,000 mg of vitamin C.
Bioavailability, Mixing and Solubility of Calcium Ascorbate Buffered Vitamin C
