Product Description:

Human cannot manufacture their own vitamin C and must rely on outside sources (food and supplements) to obtain it. In fact, we would all do well to make sure that we actually obtain adequate vitamin C, considering this nutrients extremely important role in relation to human health. This role includes its necessity for the formation of collagen protein found in skin, connective tissue, cartilage and bone; it is also an antioxidant nutrient. It is essential for wound healing, affects immune responses, helps maintain strength in blood vessels, influences formation of hemoglobin, absorption of iron from intestinal tract, and deposition of iron in liver tissue, and assists in the secretion of hormones from adrenals. Bioflavonoids (citrus, hesperidin and rutin), sometimes called vitamin P, are substances that are found wherever vitamin C is found in nature.  Bioflavonoids have been shown to improve the therapeutic action of vitamin C.(3)

The combination of 1000mg of Vitamin C with supportive flavonoids makes this a powerhouse product.  Additionally, as a sustained release (time-released) formula, its effectiveness is greatly enhanced.

Big fan of all those flavonoids like hesperidin, rutin, and quercetin.  Now that you have combined them with 1000mg of vitamin C and better yet in a time released formula, it’s my new ‘go to’ vitamin C choice.
Great product and thanks always for your super fast service.
