Sports Research® High Potency Liposomal Vitamin C Supplement 1000 mg – Certified Vegan, Non-GMO, Gluten Free | Antioxidant & Immune Support | Ascorbic Acid Vitamin C | 180 Liquid Veggie Capsules
Sports Research

Sports Research® High Potency Liposomal Vitamin C Supplement 1000 mg – Certified Vegan, Non-GMO, Gluten Free | Antioxidant & Immune Support | Ascorbic Acid Vitamin C | 180 Liquid Veggie Capsules

Why we love it
  • Superior absorption of Vitamin C.
  • Enhanced delivery to your cells.
  • Supports your immune health daily.
Main Highlights
  • LIPOSOMAL FORM: Our new Liposomal Vitamin C capsules offer an innovative form of Vitamin C coated in PureWay-C Liposomal. They are tiny, fat-like particles made of phospholipids (the same material that makes up cell membranes) that offer better absorption for digestion. This encapsulation helps improve the absorption and bioavailability of Vitamin C.*
  • ENHANCED ABSORPTION: Liposomal technology allows more Vitamin C to be delivered to your cells. Liposomal Vitamin C offers direct delivery by allowing for the fusing of encapsulated nutrients with cell membranes.*
  • BIOAVAILABILITY: The lipid bilayer mimics the cell membrane, essentially creating a familiar source for the body, thus making it easier for the liposome to merge with cells in the GI tract to allow for easier digestion of antioxidants.*
  • FORMULATED WITH ASCORBIC ACID: Vitamin C is the easiest way to add daily immune support to your healthy lifestyle all year long.* An essential micronutrient, Vitamin C gummies are a delicious way to get antioxidant support when you’re on-the-go.*
  • THE SPORTS RESEARCH DIFFERENCE: Founded in Southern California in 1980, Sports Research is a family-owned business born from a passion for fitness and wellness. Our goal is to embrace the sport of life through research-backed products created for every body—inside and out (Please remove product label before recycling bottle).
