Vitamin B3: Health Benefits, Source, And Dosage
Vitamin B3: Health Benefits, Source, And Dosage. Vitamins are very important for the excellent functioning of the body. The lack of them results to weakness, disease or even death. Vitamins work together with enzymes (chemical catalyst) thus their being called as “co-enzymes”.
Among the important vitamins needed by the body is the vitamin B complex. This is a group of vitamins that are needed in the proper functioning of the body, specially for the brain and the nervous system.
One of these B complex is vitamin B3 (niacin, niacinamide, nicotinic acid). This vitamin maintains and strengthens the gastro-intestinal tract, circulation, and the nervous system. It is needed for the protein and carbohydrate metabolism. Vitamin 3 increases blood flow to the skin and body extremities. It is good for cold hands and feet.
Vitamin 3 helps the body to produce many hormones. It is important in energy production, and in the metabolism of fat, cholesterol, and carbohydrate. Vitamin 3 is used in over 50 different chemical reactions in the body. It also helps to regulate the blood sugar, and antioxidant mechanisms. It lowers bad cholesterol, and reduces early onset of arthritis and diabetes. It is effective in the treatment of early diabetes.
Vitamin 3 mild deficiency symptoms are canker sores, irritability, insomnia, nervousness, chronic headache, digestive problems, diarrhea, and anemia. Severe deficiency symptoms include disorientation, mental dullness, pellagra, and neurasthenia.
The rich sources of vitamin 3 are brewer’s yeast, brown rice, wheat germ, rice bran, peanuts, sunflower seeds, whole wheat, torula yeast, and green vegetables.
Vitamin B3 is needed in the assimilation of vitamin C and other B vitamins. To be more effective, this vitamin should be taken together with other B vitamins because it works closely with them.
