Natural Factors C Extra 500 mg + Quercetin Bioflavonoids 500 mg (Tablets)

SKU: NF01334

Vitamin C and quercetin work better together for immune support

What It Does

This natural health product delivers comprehensive immune support through the proven combination of vitamin C and quercetin bioflavonoids. Unlike basic vitamin C supplements, this formula provides enhanced bioactivity and broader antioxidant protection.

Why It Works

  • IMMUNE FUNCTION: Vitamin C supports your immune system's natural defenses while quercetin enhances this activity.
  • ANTIOXIDANT PROTECTION: Both ingredients work as antioxidants that help protect against free radical damage.
  • COLLAGEN FORMATION: Vitamin C helps in collagen formation to maintain healthy bones, cartilage, teeth, and gums.

What's Inside

Each tablet contains 500mg of vitamin C paired with 500mg of quercetin bioflavonoids in a potent 1:1 ratio. Made in Canada by Natural Factors with quality you can trust.

Why we carry it: The research-backed combination of vitamin C and quercetin delivers enhanced immune support that single-ingredient formulas simply can't match.

Non-Medicinal Ingredients: Microcrystalline cellulose, dibasic calcium phosphate dihydrate, croscarmellose sodium, carbohydrate gum, coating (carbohydrate gum [cellulose], glycerin), stearic acid, vegetable grade magnesium stearate (lubricant), silica.

1 tablet daily with food or as directed by a health care practitioner. Consult a health care practitioner for use beyond 12 weeks.
