C-1000 is a single-ingredient vegetarian capsule delivering 1,000 mg of vitamin C as ascorbic acid per serving, manufactured by Douglas Laboratories. Each capsule is enclosed in a hydroxypropyl methylcellulose (vegetarian) shell and stabilized with ascorbyl palmitate.

Vitamin C is an essential micronutrient that supports immune function and provides antioxidant activity against reactive oxygen species. Douglas Laboratories formulates C-1000 to support the body's defense system by helping maintain white blood cell function and activity, and to promote healthy interferon levels, antibody responses, and secretion of thymic hormones. Vitamin C also helps maintain healthy mast cell function and supports lymphocyte formation.

C-1000 is suited for adults seeking daily immune and antioxidant support, and for those who prefer a straightforward, single-nutrient capsule format. The product is gluten-free and Non-GMO.
