Medical Information on Ester-C

Ester-C is a brand name for vitamin C with ascorbate calcium that is used to treat people with low levels of vitamin C and who don't get enough from their diets, according to the Kaiser Permanente website. Also known as an antioxidant, it is used to prevent damage to the body's cells.

Ascorbic Acid

Ester-C is the ascorbic acid form of vitamin C that occurs naturally in potatoes, citrus fruits, leafy vegetables and tomatoes. According to the Drugs.com website, ascorbic acid is important for muscles and bones and connective tissues. The body needs iron for red blood cell production and Ester-C aids the body in absorbing iron.

Uses

The primary use of Ester-C is to treat vitamin C deficiencies that can result in the condition scurvy, according to Kaiser Permanente. Tiredness, muscle weakness, rash, tooth loss or joint pain are some of the symptoms of scurvy. Also, some health care professionals may prescribe a vitamin regime including Ester-C to treat macular degeneration in the eye.

Dosage

Ester-C comes in many forms: powder, capsules, chewable tablets and sustained-release tablets. Depending on the treatment of your medical condition and your response, dosage can vary, according to Kaiser Permanente. Ester-C is taken orally, usually one to two times a day with food and an 8 oz. glass of water. Because vitamin C is water soluble, the body does not store it so excess amounts flush out. Therefore your body will more easily absorb vitamin C in smaller doses throughout the day.

Precautions

If taking Ester-C when breastfeeding, vitamin C passes into breast milk. It is considered to be safe, but consulting with your doctor is advisable. Do not take Ester-C if you have had an allergic reaction (rash, itching/swelling, trouble breathing or severe dizziness) to ascorbic acid, according to the website drugs.com. If you have a history of kidney stones or disease, or cirrhosis of the liver or other liver diseases, consult with your physician before starting an Ester-C supplement.

Side Effects

Although most people tolerate Ester-C well, there can be some side effects, such as heartburn, constipation or diarrhea, nausea, abdominal pain/cramps or vomiting. Consult with your physician if any of these conditions worsen or persist, according to Kaiser Permanente. Rare side effects may include pink/bloody urine or painful urination and a physician should be contacted immediately if such conditions occur.
