THE POWER OF QUERCETIN

When it comes to staying healthy, it’s important to give your body all the help it can get – that means getting a variety of nutrients to help it do its job. Because the human body can’t create its own bioflavonoids, it’s important to get these compounds from other sources. Quercetin is a non-citrus bioflavonoid which may support antioxidant activity and a healthy immune system. KAL Quercetin tablets contain 1000 mg of quercetin in each serving.

Like almost all KAL products, KAL Quercetin 1000 mg is manufactured in our own facilities. This helps us ensure our raw materials are free of contaminants and impurities, so that we can keep our promise of purity, potency and quality for each product.
