🧪 Formulation Notes

Vitamin C is considered a “staple” in any supplement routine. Its powerful antioxidant properties, ability to promote healthy skin, and support of the immune system, help maintain overall health. The buffering action of calcium ascorbate in our Buffered C lowers acidity offering better tolerance for those sensitive to gastric irritation. It also incorporates 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.

We guarantee our supplements for potency and purity

Prolonged release Gently provides antioxidant support

GF Gluten free
