Double C™

Double C™ is a Vitamin C formula designed by Life Extension scientists Durk Pearson & Sandy Shaw® for their own daily use.* Double C helps fight free radicals throughout your body with a scientifically-designed formulation of water- and fat-soluble Vitamin C (as calcium ascorbate and ascorbyl palmitate).* Plus Double C is more desirable for these reasons.

  • Is gentler on your stomach — calcium ascorbate is nonacidic, unlike ascorbic acid
  • Contains ascorbyl palmitate, a naturally-occurring antioxidant synergist*
  • Designed to maximize absorption and bioavailability — operates in both lipid and aqueous tissue
  • Uses superior, high stability Hoffmann-La Roche ingredients

Suggested Use: For adults only. Take one capsule with each meal as a dietary supplement. Contains no fillers, pollens, soy, wheat, or yeast products, which may cause allergic responses in some persons.

Caution: Not for use by children or by pregnant or lactating women. Not for use by anyone sensitive to any of the ingredients. Taking large doses of Vitamin C (several grams or more) all at once, especially on an empty stomach, can cause gastric upset and diarrhea. This product contains 1,710 mg of Vitamin C in the recommended dose of 3 capsules per day. Persons with the rare genetic disorder 6-GPD deficiency should not use such large Vitamin C supplements unless directed by a physician.
