Quercetin Complex


Your body is bombarded by foreign substances from the outside world daily. Practically everything you touch, from doorknobs to your cell phone, is covered in tiny microorganisms. And while not all microorganisms are bad, there are those that are less favorable to us. Your immune system protects your body from external threats and keeps you healthy. That’s why it’s so important to nurture your immune system by giving it the energy and nutrients needed for optimal function. Our Quercetin Complex with Vitamin C can provide you with immune system support.**

Quercetin is a natural plant pigment that is a non-citrus bioflavonoid. It is found in foods such as green and black tea, onions, apples and other fruits and vegetables. For immune system support, this special formula also features Ester C®, which is a buffered, non-acidic, and well absorbed form of Vitamin C, a potent antioxidant that helps neutralize harmful free radicals in cells.** What’s more, Vitamin C plays an important role in the functioning of white blood cells, which are vital components of the immune system, and can also support upper respiratory health, promote iron absorption, and support healthy blood vessels.**

Ester-C® provides a unique, pH neutral (non-acidic), form of vitamin C that is gentle on the stomach. This product also offers the additional benefits of incorporating acerola berry, citrus bioflavonoids, rutin and rose hips, plus bromelain, a naturally sourced enzyme derived from pineapple.

If you’re looking for gentle support for your immune system and for your overall health and wellness, this supplement is the right choice for you.
