Two antioxidants that block histamines, in one supplement! May reduce oxidation of LDL (bad) cholesterol! How Does Liquid Vitamin C with Quercetin Work? Liquid Vitamin C with Quercetin combines two antioxidants in one supplement. Vitamin C, or ascorbic acid, is a natural antihistamine, and quercetin enhances the vitamin's function. Vitamin C is important in forming collagen, a protein that gives structure to bones, cartilage, muscle, and blood vessels. It also aids in the absorption of iron and helps maintain capillaries, bones, and teeth. Vitamin C is also essential for a healthy immune system. Quercetin, naturally found in apples, tea, and red wine, is a type of flavonoid (plant pigment) that may help fight cell-damaging free radicals and reduce the oxidation of LDL ("bad") cholesterol. The combination of vitamin C and quercetin may promote the rebuilding of small blood vessels and other structural parts of the body, promote a healthy immune system, and act as a potent antioxidant. NSI Liquid Vitamin C with Quercetin is better because it:. Contains only USP pharmaceutical grade ascorbic acid. Offers high-potency dosage in convenient liquid form! . Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.

"Nice way to get this much Vitamin C without having to swallow pills. I recommend that you use this product mixed in juice or your protein drink. The flavor is easily disguised. I would not recommend you drink it without mixing as the flavor is not exceedingly pleasant. Hope this helps..."
