Natrol brand supplement Quercetin 500 combines the power of quercetin with vitamin C and citrus bioflavonoids - providing a naturally beneficial blend of plant origin. Its advanced formula improves immune system function.

The product includes:

• Vitamin C - L-ascorbic acid, is by far one of the most popular and essential vitamins for the body. It has antioxidant properties, strengthens teeth and gums, improves immune function and facilitates wound healing.
• Quercetin - (Latin: quercetum literally: oak forest) (English: Quercetin) is an organic aromatic compound of plant origin. It is characterised by its bitter taste, making it a common ingredient in foods and drinks. Quercetin is found in large quantities in fruits (apples, red grapes, strawberries) and vegetables (onions, kale, spinach, broccoli).
• Citrus bioflavonoid complex - (derived from lemon, orange, lime, mandarin, among others). The bioflavonoids and glycosides from, amongst others, grapefruit oil, support normal intestinal function. As a result, it has a beneficial effect on the body's immune protection.

The gel capsule formula makes taking the supplement even easier. The recommended daily serving is two capsules per day with a meal.
