Vitamin C

Vitamin C

For centuries, the Amazon's indigenous people have gathered wild Camu Camu berries (the world's richest source of natural Vitamin C) to protect and enhance their health and immune systems. Today, with The Synergy Company's support, these native communities are saving their homeland from the destructive practice of clear-cutting the rainforest as they create a sustainable economy based on the tradition of wildcrafting Camu Camu.

In Pure Radiance C, we blend our wild Camu Camu with certified organic, antioxidant rich berries and sprouts. This exquisite formula was the very first organic, 100% whole food Vitamin C supplement. Bursting with all of the proven goodness of natural Vitamin C and its naturally occurring co-factors.
Dr. Mercola's Liposomal Vitamin C uses liposomes (fat) to increase the bioavailability of vitamin C, since water-soluble vitamin C is not absorbed well. Liposomal Vitamin C can also potentially ease intestinal discomfort associated with taking high amounts of vitamin C.
Dr. Mercola has been providing quality products since 2001.

Vitamin C

Vitamin C, also known as ascorbic acid, is a water-soluble nutrient found in some foods. In the body, vitamin C acts as an antioxidant, helping to protect cells from the damage caused by free radicals. Free radicals are compounds formed when our bodies convert the food we eat into energy. People are also exposed to free radicals in the environment from cigarette smoke, air pollution, and ultraviolet light from the sun.

The body also needs vitamin C to make collagen, a protein required to help wounds heal. In addition, vitamin C improves the absorption of iron from plant-based foods and helps the immune system work properly to protect the body from disease.

The body is not able to make vitamin C on its own, and it does not store vitamin C. It is therefore important to include plenty of vitamin C-containing foods in your daily diet.


Which foods contains vitamin C?

All fruits and vegetables contain some amount of vitamin C.

Fruits with the highest sources of vitamin C include:

  • Cantaloupe
  • Citrus fruits and juices, such as orange and grapefruit
  • Kiwi fruit
  • Mango
  • Papaya
  • Pineapple
  • Strawberries, raspberries, blueberries, cranberries
  • Watermelon

Vegetables with the highest sources of vitamin C include:

  • Broccoli, Brussels sprouts, cauliflower
  • Green and red peppers
  • Spinach, cabbage, turnip greens, and other leafy greens
  • Sweet and white potatoes
  • Tomatoes and tomato juice
  • Winter squash


Some cereals and other foods and beverages are fortified with vitamin C. Fortified means a vitamin or mineral has been added to the food. Check the product labels to see how much vitamin C is in the product. Cooking vitamin C-rich foods or storing them for a long period of time can reduce the vitamin C content. Microwaving and steaming vitamin C-rich foods may reduce cooking losses. The best food sources of vitamin C are uncooked or raw fruits and vegetables.


Vitamin C deficiency

Serious side effects from too much vitamin C are very rare, because the body cannot store the vitamin. However, amounts greater than 2,000 mg/day are not recommended because such high doses can lead to stomach upset and diarrhea.

Too little vitamin C can lead to signs and symptoms of deficiency, including:

  • Anemia
  • Bleeding gums
  • Decreased ability to fight infection
  • Decreased wound-healing rate
  • Dry and splitting hair
  • Easy bruising
  • Gingivitis (inflammation of the gums)
  • Nosebleeds
  • Possible weight gain because of slowed metabolism
  • Rough, dry, scaly skin
  • Swollen and painful joints
  • Weakened tooth enamel

A severe form of vitamin C deficiency is known as scurvy, which mainly affects older, malnourished adults.


What kinds of vitamin C dietary supplements are available?

Most multivitamins have vitamin C. Vitamin C is also available alone as a dietary supplement or in combination with other nutrients. The vitamin C in dietary supplements is usually in the form of ascorbic acid, but some supplements have other forms, such as sodium ascorbate, calcium ascorbate, other mineral ascorbates, and ascorbic acid with bioflavonoids.


Am I getting enough vitamin C?

Most people get enough vitamin C from foods and beverages. However, certain groups of people are more likely than others to have trouble getting enough vitamin C:

  • People who smoke and those who are exposed to secondhand smoke, in part because smoke increases the amount of vitamin C that the body needs to repair damage caused by free radicals. People who smoke need 35 mg more vitamin C per day than nonsmokers.
  • Infants who are fed evaporated or boiled cow's milk, because cow's milk has very little vitamin C and heat can destroy vitamin C. Cow's milk is not recommended for infants under 1 year of age. Breast milk and infant formula have adequate amounts of vitamin C.
  • People who eat a very limited variety of food.
  • People with certain medical conditions such as severe malabsorption, some types of cancer, and kidney disease requiring hemodialysis.


What are some effects of vitamin C on health?

Scientists are studying vitamin C to understand how it affects health:

  • Cancer prevention and treatment. People with high intakes of vitamin C from fruits and vegetables might have a lower risk of getting many types of cancer, such as lung, breast, and colon cancer. However, taking vitamin C supplements, with or without other antioxidants, doesn't seem to protect people from getting cancer. It is not clear whether taking high doses of vitamin C is helpful as a treatment for cancer. Vitamin C's effects appear to depend on how it is administered to the patient. A few studies in animals and test tubes indicate that very high blood levels of vitamin C might shrink tumors. But more research is needed to determine whether high-dose intravenous vitamin C helps treat cancer in people. Vitamin C dietary supplements and other antioxidants might interact with chemotherapy and radiation therapy for cancer. People being treated for cancer should talk with their oncologist before taking vitamin C or other antioxidant supplements, especially in high doses.

  • Cardiovascular disease. People who eat lots of fruits and vegetables seem to have a lower risk of cardiovascular disease. Researchers believe that the antioxidant content of these foods might be partly responsible for this association because oxidative damage is a major cause of cardiovascular disease. However, scientists aren't sure whether vitamin C itself, either from food or supplements, helps protect people from cardiovascular disease. It is also not clear whether vitamin C helps prevent cardiovascular disease from getting worse in people who already have it.

  • Age-related macular degeneration (AMD) and cataracts. AMD and cataracts are two of the leading causes of vision loss in older people. Researchers do not believe that vitamin C and other antioxidants affect the risk of getting AMD. However, research suggests that vitamin C combined with other nutrients might help keep early AMD from worsening into advanced AMD. More research is needed before doctors can recommend dietary supplements containing vitamin C for patients with AMD. However, people who have or are developing the disease might want to talk with their doctor about taking dietary supplements. The relationship between vitamin C and cataract formation is unclear. Some studies show that people who get more vitamin C from foods have a lower risk of getting cataracts. But further research is needed to clarify this association and to determine whether vitamin C supplements affect the risk of getting cataracts.
  • The common cold. Although vitamin C has long been a popular remedy for the common cold, research shows that for most people, vitamin C supplements do not reduce the risk of getting the common cold. However, people who take vitamin C supplements regularly might have slightly shorter colds or somewhat milder symptoms when they do have a cold. Using vitamin C supplements after cold symptoms start does not appear to be helpful.
