Vitamin B supplements are available to purchase online , but people should check first with a doctor to make sure they are safe to take. The following foods are good sources of vitamin B Foods that are high in tryptophan are good sources of niacin.
The body needs tryptophan to make protein, but if there is extra, it can convert it to niacin. In countries where corn and rice are the main sources of nutrition , pellagra is still a public health problem. Corn and rice have low levels of vitamin B. In , the U. Public Health Service asked Dr. Joseph Goldberger to go to the South of the country to investigate and deal with pellagra.
Rates of pellagra were much higher in the southern states than in the north. Goldberger inspected prisons, psychiatric hospitals, and orphanages. He found that pellagra rates among the children, prisoners, and patients were considerably higher than rates among the staff, and he concluded that pellagra was not an infection, but that it was probably related to diet.
In , scientists confirmed the niacin connection. Niacin can both prevent and cure pellagra. Now, pellagra is rare in the U. Vitamin E oil is thought to have benefits for a wide range of skin and nail conditions, including treating dry skin, preventing skin cancer, treating…. Vitamin B is an essential vitamin necessary for healthy nerve tissue, brain function, and red blood cell production. Your body gets niacin through food, but it also makes small amounts from the amino acid tryptophan, which can be found in protein sources like turkey and other animal foods 1.
Niacin is one of eight water-soluble B vitamins. Furthermore, it plays a role in cell signaling and making and repairing DNA, in addition to acting as an antioxidant 2. These are some of the symptoms of niacin deficiency 1 :. That said, deficiency is very rare in most Western countries. Severe niacin deficiency, or pellagra, mostly occurs in developing countries, where diets are not as varied.
It can be treated with niacinamide supplementation 1. Niacin is a vitamin that acts as an antioxidant and plays a role in cell signaling and DNA repair. Deficiency is characterized by skin problems, memory loss, and digestive problems. For ages 7 months and older, it is expressed as mg niacin equivalents NE. One NE is equal to 1 mg of niacin or 60 mg of tryptophan 1.
The recommended amount of niacin depends on your age and gender. Men need 16 mg NE per day, while women who are not pregnant or breastfeeding need 14 mg NE per day.
This may translate to a decrease in heart disease risk, although several studies have found no link between niacin supplementation and a decrease in heart disease risk or deaths 4 , 5. It also takes high doses of niacin, typically 1, mg or greater, to achieve blood fat level improvements, which increases the risk of experiencing unpleasant or potentially harmful side effects 6.
For these reasons, niacin is not a primary treatment for high cholesterol. One role of niacin is to release prostaglandins, or chemicals that help your blood vessels widen — improving blood flow and reducing blood pressure. For this reason, niacin may play a role in the prevention or treatment of high blood pressure 8.
A high quality study also noted that single doses of mg and mg of niacin slightly reduced right ventricular systolic pressure 9. Type 1 diabetes is an autoimmune disease in which your body attacks and destroys insulin-creating cells in your pancreas. On one hand, it can help lower the high cholesterol levels that are often seen in people with type 2 diabetes. On the other, it has the potential to increase blood sugar levels.
As a result, people with diabetes who take niacin to treat high cholesterol also need to monitor their blood sugar carefully Fortunately, a more recent review of studies found that niacin did not have significant negative effects on blood sugar management in people with type 2 diabetes When rats with ischemic stroke were given niacin, their brains grew new blood vessels , according to researchers at Henry Ford Hospital in Detroit, Michigan.
Ischemic stroke is caused by an obstruction within a blood vessel supplying blood to the brain and accounts for 87 percent of all cases. A study published in the journal Stroke also used rats and found that treatment with nicotinamide may repair damage to the brain caused by strokes.
Vitamin B3 may also be helpful to cancer patients. A recent study found that nicotinamide significantly reduces the incidence of nonmelanoma skin cancers in those with a history of basal cell carcinoma or squamous cell carcinoma. It may be good for other skin conditions, too. In a double-blind trial by the State University of New York , the topical application of a 4 percent niacinamide gel twice a day for two months resulted in a similar acne improvement when compared to 1 percent clindamycin gel.
Those who have intimacy problems may also benefit from niacin. According to a study published in the Journal of Sexual Medicine, vitamin B3 was found to improve the ability to maintain an erection in men with moderate to severe erectile dysfunction.
A recent animal study suggested that niacin may be helpful in preventing inflammatory bowel disease and colitis. The study, published in Scientific Reports , found that rats that were given niacin and then induced with colitis saw less colonic damage than those who did not receive niacin.
The authors attribute this protection to niacin's anti-inflammatory and anti-angiogenic effects. Angiogenic means the formation and development of blood vessels.
