About this item

  • FIGHT OXIDATIVE STRESS – Vitamin C helps fight oxidizing free radicals, which is good for you from your head to your toes. Quercetin does too—the only problem is absorption.Our quercetin is wrapped in a phytosome, which makes it 50 times more bioavailable than traditional quercetin.
  • ENCOURAGE HEALTHY IMMUNE FUNCTION - Quercetin and vitamin C both promote immune health: in a randomized clinical trial, quercetin encouraged a healthy immune response in physically fit older adults—and we all know how much immune challenges want a taste of 1000 mg of vitamin C!
  • PROMOTE OVERALL HEALTH – Quercetin helps promote a healthy inflammatory response. Vitamin C encourages healthy iron uptake as well as collagen production. Plus, what vitamin Cdoes for your body is complemented by quercetin. In fact, vitamin C and bioflavonoids are often present together in healthy foods such as fruits and vegetables, and citrus fruit.
  • INGREDIENTS MATTER - Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free, and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.
  • LIVE YOUR HEALTHIEST LIFE - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. Our formulations are created using the ingredients and dosages used in the studies that inspired them, ensuring that maximum bioavailability and efficacy is achieved.

Product Description

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.
