Optimized Antioxidant Activity

The benefits of vitamin C are energized in this formula, which is designed to make more vitamin C available for immune support and free radical scavenging. After vitamin C carries out its antioxidant function of neutralizing free radicals, it is oxidized and spent. The unique blend of compounds in Systemic C™, including alpha-lipoic acid, N-acetyl cysteine, quercetin, and grape seed extract, help to reactivate and recycle vitamin C in the body. This provides the body with increased antioxidant activity, an upgraded, robust C for healthy aging, immune health and heart health. Reactivating vitamin C allows this important vitamin to continue its vital functions.

Vitamin C is surely one of the most important nutrients for our health. Its powerful antioxidant qualities support our skin, bones, metabolism, and immune function; it supports our hearts and cardiovascular systems and helps healthy aging. Source Naturals now introduces Systemic C, an enhanced, upgraded vitamin C for even greater antioxidant benefits.

The unique blend of nutrients in Systemic C is designed to reactivate and recycle vitamin C in the body to provide increased antioxidant activity. Compounds including alpha-lipoic acid, N-acetyl cysteine, quercetin, and grape seed extract add additional antioxidant protection for your body. The vitamin C in this formula is a non-acidic form, calcium ascorbate, a great benefit to all who have sensitivities to ascorbic acid.

Source Naturals is pleased to present you with Systemic C, the non-acidic vitamin C, with enhanced antioxidant activity.

Free Radicals and Antioxidants

Modern life, with our constant bombardment by pollutants, excess sunlight, unnatural foods, chemical toxins, and electromagnetic radiation, produces damaging free radicals. Free radicals are also natural byproducts of such physical processes as respiration and mitochondrial energy generation. Free radicals are unstable molecules. Because they seek stability, they damage cells and tissues as they steal electrons from other, healthy molecules. As more molecules damage others, a cascade effect begins. This can result in signs of aging, cellular imbalances and many other health concerns.

Combating free radicals are antioxidants. An antioxidant is a molecular compound that readily lets go of its outer electron, which it donates to the free radical. This process completes and stabilizes the free radical, so it no longer has the need to find an electron from another molecule that is a part of healthy tissue. Our bodies produce natural antioxidants, but this process decreases as we age.

The Benefits of Vitamin C

For decades, the conventional means of obtaining sufficient vitamin C was through ascorbic acid, the pure six-carbon hexose derivative. Now, however, because of the importance of vitamin C, scientists may have discovered a means of helping the body obtain more vitamin C for increased antioxidant protection. Nutrients added to vitamin C may “recycle” vitamin C that has been spent (oxidized) after neutralizing free radicals, by putting it back to work protecting your cells.

Systemic C

Systemic C combines vitamin C from calcium ascorbate with highly powerful antioxidant compounds that are intended to heighten its benefits:

• Alpha-Lipoic Acid, a renowned antioxidant, scavenges hydroxyl radicals, nitric oxide, peroxynitrite, hydrogen peroxide hypochlorite, serperoxide and peroxyl free radicals.

• N-Acetyl Cysteine replenishes intracellular glutathione depleted by free radicals such as hydrogen peroxide and hydroxyl radicals.
Quercetin has metal-chelating and stabilizing properties. It is also a strong inhibitor of lipid peroxidation through scavenging of peroxide radicals, which strongly oxidize and deplete ascorbic acid.

• Grape Seed Extract: The proanthocyanidins in grape seed extract inhibit the production of free radicals, thereby increasing the function of the cells’ own antioxidants, such as glutathione and ascorbic acid. The evidence and scientific research continue to mount in worldwide clinical exams and tests: vitamin C is one of the most important benefits to your health available today. In the SystemiCare model of health care, seven of the twelve deep metabolic systems—Inflammation Response, Antioxidant Defense, Circulation, Immunity, Liver/ Detox, Metabolism/Hormones, Structure/ Connective Tissue—are positively supported by this phenomenal vitamin. It is an unparalleled key to health and well-being.
