Vitamin B5, also called pantothenic acid, is one of 8 B vitamins. All B vitamins help the body convert carbohydrates into fuel (glucose), which is used to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein. B complex vitamins are needed for healthy skin, hair, eyes, and liver. They also help the nervous system function properly.
All B vitamins are water-soluble, meaning that the body does not store them and must be replenished daily.
In addition to playing a role in the breakdown of fats and carbohydrates for energy, vitamin B5 is critical to the manufacture of red blood cells, as well as sex and stress-related hormones produced in the adrenal glands atop the kidneys. Vitamin B5 is also important in maintaining a healthy digestive tract, and it helps the body use other vitamins, particularly B2 or riboflavin. It is sometimes called the “anti-stress” vitamin.
Your body needs pantothenic acid to synthesize cholesterol.
It is rare for anyone to be seriously deficient in vitamin B5. Symptoms of a vitamin B5 deficiency include fatigue, insomnia, depression, irritability, vomiting, stomach pains, burning feet, and upper respiratory infections.
High Cholesterol/High Triglycerides
Several small, double-blind studies suggest that pantethine may help reduce triglycerides, or fats, in the blood in people who have high cholesterol. In some of these studies, pantethine has also helped lower LDL (bad) cholesterol and raise HDL (good) cholesterol. In some open studies, pantethine seems to lower levels of cholesterol and triglycerides in people with diabetes.
Wound Healing
Studies, mostly in test tubes and animals but a few on people, suggest that vitamin B5 supplements may speed wound healing, especially following surgery. This may be particularly true if vitamin B5 is combined with vitamin C.
Rheumatoid Arthritis
Some early evidence suggests that pantothenic acid might help with symptoms of rheumatoid arthritis (RA). One study found that people with RA may have lower levels of B5 in their blood than healthy people, and the lowest levels were associated with the most severe symptoms. A small study conducted in 1980 concluded that 2,000 mg/day of calcium pantothenate improved symptoms of RA, including morning stiffness and pain.
Dietary Sources
Pantothenic acid gets its name from the Greek root pantos, meaning “everywhere,” because it is available in a wide variety of foods. A lot of vitamin B5 is lost when you food is processed, however. Fresh meats, vegetables, and whole unprocessed grains have more vitamin B5 than refined, canned, and frozen food. The best sources are brewer’s yeast, corn, cauliflower, kale, broccoli, tomatoes, avocado, legumes, lentils, egg yolks, beef (especially organ meats such as liver and kidney), turkey, duck, chicken, milk, split peas, peanuts, soybeans, sweet potatoes, sunflower seeds, whole-grain breads and cereals, lobster, wheat germ, and salmon.
Upper Limits
The Council for Responsible Nutrition recommends an upper limit of 1,000 mg / day for pantothenic acid, citing the lack of adverse effects with daily intakes as high as 10 g.
