Description
Quercetin is a flavonol, one of six subclasses of plant pigments called flavonoids which give many fruits, vegetables and flowers their colours. Flavonoids are antioxidants that hunt for free radicals in the body, which can damage cell membranes and affect DNA. These damages affect various systems of the body, including the nervous, cardiovascular, skeletal, respiratory and more. Antioxidants help neutralize free radicals by reducing and preventing the damage they cause.
Quercetin is used in herbal medicine as a capillary protectant, antihistamine, and antioxidant.

Frequently Asked Questions
What is CanPrev and are its supplements Health Canada approved?
CanPrev is a Canadian natural health supplement brand founded in 2005 by Tanya Salituro -- the name stands for Canadian + Preventive. All products are Health Canada licensed and manufactured at site-licensed, government-approved Canadian facilities, with each batch independently laboratory tested for potency, purity, and safety before release. The brand offers 445+ formulations across therapeutic categories including magnesium, amino acids, vitamin D, hormonal support, and women's health, distributed in 3,400+ Canadian retail locations and through naturopathic practitioners. In February 2025, CanPrev was acquired by Apotex, further expanding its distribution infrastructure.
How is CanPrev different from other Canadian supplement brands?
CanPrev's distinguishing feature is practitioner co-formulation: roughly 25% of the company team are licensed health practitioners -- naturopathic doctors, nutritionists, and herbalists -- meaning products are formulated with clinical input from the start, not adapted for retail after development. The brand consistently selects more bioavailable nutrient forms: methylcobalamin over cyanocobalamin for B12, magnesium bisglycinate over magnesium oxide, active folate (5-MTHF) over folic acid -- at therapeutic doses, and formulates without fillers or binders. This distinguishes CanPrev from mainstream supplement brands that use lower-cost, less-absorbed nutrient forms to reduce per-unit manufacturing costs.
