Product Description:

Humans cannot manufacture their own vitamin C and must rely on outside sources (food and supplements) to obtain it.  Vitamin C is necessary for the formation of collagen protein found in skin, connective tissue, cartilage and bone.  It is also an important antioxidant nutrient essential for wound healing, immune responses, strength of blood vessels,  formation of hemoglobin, absorption of iron and the secretion of hormones. Bioflavonoids (citrus, hesperidin and rutin) are substances that are found in nature wherever vitamin C is found.  They help improve the action of vitamin C.

The combination of 1000mg of Vitamin C with supportive flavonoids makes this a powerhouse product.  For maximum benefit, this is a sustained (time) released formula.

Before taking this or any over-the-counter product, it is always advisable to discuss its use with your primary care professional.

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.
