Introduction

Quercetin is a natural food polyphenol with potential effectiveness in decreasing weight gain and obesity. It is found in fruits and vegetables, including onions, apples, and kale.

Studies have also revealed that quercetin may be advantageous in diminishing the risk of heart disease, cancer, and stroke.

Quercetin is found in the peel of apples, but you can maximize your input by consuming the whole fruit rather than drinking apple juice.

The peels have an increased concentration of quercetin than the flesh. So if you eat the whole apple rather than just consuming its juice, your body absorbs more.

The best quercetin plus supplement in France is an antioxidant that resists free radicals in the body. Free radical impairment has been linked to cancer and heart disease. It also allows you to increase your immune system and decrease inflammation.

Onions, citrus fruits, and tea also contain quercetin. It is sold in the form of capsules or tablets under different brand names as a dietary supplement.

The best quercetin supplements in France are much more potent than the quercetin you encounter naturally in food sources. Therefore, take quercetin pills to decrease the risk of cancer and heart disease.
