What Is Vitamin C?

Vitamin C and Bio-Quercetin is a high-potency vitamin C supplement with an ultra-absorbable form of quercetin. Vitamin C supports immune health, collagen production, a healthy cardiovascular system and more. Quercetin is a flavonoid that complements vitamin C’s health benefits.

Quercetin complements vitamin C, inhibiting oxidative stress and inflammation to support cardiovascular health.

Vitamin C Benefits

Vitamin C is a powerful essential nutrient that provides profound whole-body health benefits. This supplement delivers 1,000 mg of vitamin C, plus 15 mg of an ultra-absorbable quercetin, which complements vitamin C’s activity in supporting whole-body health.

Antioxidant protection, immune health and more

Getting enough vitamin C is vitally important for overall health but the human body can't make it, so you have to get vitamin C through diet or supplements.1 In fact, some studies have shown that vitamin C supplementation supports certain aspects of cardiovascular health.2

Plus, vitamin C's biological activity is complemented by the health benefits of the flavonoid quercetin. In fact, vitamin C and bioflavonoids are often present together in healthy foods such as fruits and vegetables, notably citrus fruits.3

Ultra-absorbable quercetin for immune health and more

There's a long tradition of using quercetin to relieve the effects of seasonal immune challenges. In a randomized clinical trial, quercetin supplementation encouraged a healthy immune response in physically fit older adults.4

Another randomized controlled trial found similar results in trained athletes.5 And in double-blind clinical trials, quercetin promoted a healthy inflammatory response, reduced oxidative stress and helped maintain overall health.6,7
