How It Helps

Cooper Complete Natural Vitamin C supplement supplies 850 mg of vitamin C (as calcium and magnesium ascorbates), along with calcium and magnesium as mineral ascorbates, and 100 mg of citrus bioflavonoids (from citrus fruit), superoxide dismutase (from vegetable culture), and catalase (from vegetable culture). Mixed ascorbates rather than ascorbic acid are used in this formulation as mixed ascorbates are less likely to cause digestive distress when taken in higher amounts. Vitamin C has anti-inflammatory, antioxidant, and immune-enhancing properties.

Vitamin C is used in the body to produce collagen, a component of connective tissue. An important structural element in blood vessel walls, skin, gums, and bones, collagen is important for surgery recovery and wound healing.

Each bottle of Natural Vitamin C contains 100 tablets. The daily recommended serving is one vitamin C tablet or as recommended by your physician.

This supplement is an option for individuals who have been advised by their physician that they need additional vitamin C supplementation.

7 Questions
Ask a Question

Is it better to take vitamin C supplements with or without food?


Vitamin C is one of the water-soluble vitamins, so it can be taken on an empty stomach with a glass of water (although taking it with food will also be okay).


Can vitamin C increase the risk of kidney stones?


A review of three observational studies that included almost 155,000 women and 40,000 men found that men who took 1000 mg or more of vitamin C each day had an almost 19 percent increased risk of kidney stones than the men who took less than 90 mg per day. This increased risk of kidney stones was not seen in women.


Is there anyone who should not take vitamin C?


Individuals with hemochromatosis should talk with their physician or health care provider before taking Natural Vitamin C 1000 Supplement as higher doses of vitamin C can worsen iron overload.


Can Natural Vitamin C 1000 Supplement cause diarrhea, nausea and/or stomach cramps?


Vitamin C is a water-soluble vitamin, which means whatever is consumed or taken and not needed is eliminated by the body. However, taking too much vitamin C can cause GI discomfort, including diarrhea, nausea and/or stomach cramps.


Do some people need more Vitamin C than others?


The National Institutes of Health recommends people who smoke or are regularly exposed to secondhand smoke need 35 mg more vitamin C each day than nonsmokers.


Is there Vitamin C in Cooper Complete multivitamins?


Yes. Basic One multivitamins and the Healthy Body Pack contain 350 mg of vitamin C, while Cooper Complete Original multivitamins contain 500 mg of vitamin C per daily serving.


In what foods is vitamin C found?


Vitamin C is naturally found in many fruits and vegetables. Citrus fruits, cantaloupe, berries, kiwifruit and mango are rich sources of vitamin C. Cruciferous vegetables (broccoli, cauliflower and Brussels sprouts), potatoes, peppers and leafy greens contain vitamin C. Manufactured beverages, cereals and other foods are sometimes fortified with vitamin C.
