Formulation Notes

Prolonged C for cellular protection Every vitamin routine should include the antioxidant protection offered by vitamin C. A daily supplement regimen with Performance Vitamin C offers powerful protection against free radical damage, helps keep capillary walls and blood vessels strong, and supports healthy teeth, gums, and bones. Because vitamin C is water-soluble, it needs to be replenished on a daily basis.

Prolonged release is an advanced manufacturing technique which allows nutrients to be released slowly (over approximately 2-4 hours) promoting optimal assimilation.

Contains no artificial colors, flavors or preservatives; no wheat, gluten, milk, eggs, peanuts, tree nuts, soy, crustacean shellfish or fish.
