1000 mg, 250 capsules


Vitamin C, or ascorbic acid, is a white, crystalline, water-soluble substance found in citrus fruits and green vegetables. As an antioxidant, vitamin C scavenges free radicals in the body and protects tissues from oxidative stress. 15-18 Vitamin C also promotes the absorption of iron, while preventing its oxidation. 19-21 Vitamin C is a vital cofactor to the formation of collagen, the connective tissue that supports arterial walls, skin, bones, and teeth. 22-24*

More vitamin C is contained in the adrenal glands than any other organ in the body and is required at higher levels during times of stress. 25-28 Physical stresses on the body such as ingestion of heavy metals, 29-34 cigarette smoking, 35-38 infections, 39-43 extreme temperatures, 44-48 and chronic use of certain medications such as aspirin also signal the need for increased intake of vitamin C. 49

Along with ascorbic acid, vitamin C also comes in at least two other forms: chemically bonded to minerals as ascorbates, and as the fat-soluble ascorbyl palmitate. Both of these forms are non-acidic.

One capsule daily with meals, or as directed by a healthcare professional.


A prophylactic dosage of 2.5 to 6 grams of various forms of vitamin C daily is recommended.


Up to 15 grams daily may be taken under physician supervision.


Large doses of ascorbic acid or ascorbates and any dose of ascorbyl palmitate should be consumed with meals.


All vitamin C products should be stored away from heat, light, and moisture although this is most important for pure ascorbic acid and ascorbyl palmitate powders.


Ascorbic acid is the acidic form of vitamin C, and even when encapsulated can cause gastric upset or diarrhea for some people. This can often be alleviated by consuming it with meals. Start with a low dose then gradually increase.

If you have a stomach ulcer, use of an antacid, buffering agent, or a buffered form of vitamin C. Calcium carbonate and magnesium oxide are effective antacids. Unbuffered ascorbic acid in the mouth may be harmful to tooth enamel.
