PillsVitamins are essential for health and wellness and are essential for growth. A deficiency or an excess of vitamins can lead to disease. Here is a list of three commonvitamins that can be toxic to the body if taken in excess.

Folic acid: This important vitamin is essential for energy production and the formation of red blood cells. If high doses (15 mg or more) are taken over several months, sleep disturbances, nausea, irritability anorexia, flatulence and malaise can develop. The recommended dose of folic acid is 400mcg as a standard dose and 800 mcg in pregnancy. In order to avoid problems with the central nervous system it is best to take high doses of more than 750 mcg of folic acid with B12 supplementation.

P.A.B.A (para amino benzoic acid): Up to 1,000 mg daily is generally safe. However, people who are especially sensitive may experience skin rash, nausea, and fever at this dose. Natural sources of P.A.B.A can be found in rice, lentil, wheat, oats, seed germ, kernals, nuts, yeast, soy, beans, peas and egg yolk.

Vitamin A: Standard doses range form 10,000 to 25,000 IU daily. In excess, this vitamin can be toxic and can cause transient hydrocephalus and vomiting. Long term vitamin A use should allow the patient to take the supplement for three weeks and then stop for one week. The week without the supplement gives time for the liver to clear the vitamin A out of the system. Toxic effects of vitamin A can cause fatigue, lethargy, bone or joint pain, headaches, insomnia, dry skin, hair loss, edema, enlarged liver and spleen, abnormal bone growth and many other problems.
