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
