Vitamin C, also known as ascorbic acid, is an important nutrient that helps build and repair tissue in the body, according to the University of Maryland Medical Center. Because the body cannot store this water-soluble vitamin, you need to replenish the supply from food sources. If you cannot get enough from food sources, your physician may recommend a supplement. Ascorbic acid powder is a good option for those who cannot swallow solid forms of vitamin C, because it can be added to a beverage or sprinkled over food.
Health Benefits
Aside from assisting with the growth and repair of new tissue, vitamin C powder acts as an antioxidant within the body. The Linus Pauling Institute at Oregon State University explains that even small amounts of the vitamin can protect the body's cells from free radicals released during normal metabolism and from exposure to toxic substances. Vitamin C also assists with the creation of norepinephrine, a neurotransmitter in the brain that plays a role in mood stabilization.
Vitamin C Deficiency
Vitamin C deficiency can lead to scurvy, a condition characterized by muscle weakness, bleeding under the skin, fatigue, depression, swollen gums and loose teeth, according to Drugs.com. Some medical conditions may increase the risk of vitamin C deficiency, including alcoholism, cancer, prolonged infections, AIDS, stomach ulcer and stress. Smokers, patients on hemodialysis and people exposed to cold temperatures for a long period may also require extra vitamin C.
Side Effects
Ascorbic acid powder is typically safe when taken in recommended doses by healthy people, although in rare cases it can cause heartburn, headaches or upset stomach. Taking too much of the vitamin, however, can cause serious side effects, including kidney stones, nausea and severe diarrhea, dizziness and fatigue. MayoClinic.com explains that large doses can also cause destruction of red blood cells. Follow your physician's recommendations, and do not take more ascorbic acid powder than prescribed.
Recommended Daily Requirement
The recommended daily requirement of vitamin C is low and varies depending on your age and condition. Men age 19 and older require 90 mg per day, while women of the same age require 75 mg per day, according to MayoClinic.com. Smokers and pregnant or breastfeeding women may require slightly more. Daily vitamin C intake should not exceed 2,000 mg per day.
Vitamin C Skin Creams
A variety of skin creams and anti-aging solutions use vitamin C powder as an added ingredient. The New Zealand Dermatological Society explains that while vitamin C may be effective at reducing the effects of sun damage to the skin when used in a stable topical formula, most commercial skin creams contain very low doses and do not allow for complete absorption of the antioxidant.
