Pantothenic Acid or vitamin B5 is an important vitamin known to help in providing our bodies with energy we need from the food we consume. The main function of B5 is to break down fats . Although deficiency is rare, in cases of severe deficiency, extreme tiredness (anemia), irritability, restlessness, stomach pain, heartburn, diarrhea, nausea, loss of appetite, and burning and numbing of hands and feet, were observed . In general, studies are being conducted on vitamin B5 to observe changes in cholesterol and in reducing triglyceride levels . For example, a study has shown that those who followed a lifestyle change along with 600 mg/day for 8 weeks then 900 mg/day for 8 weeks had significantly lower levels total cholesterol and LDL (“bad cholesterol) which is more than the effects observed with only the therapeutic lifestyle change . So far, the results of these studies are promising but more research is needed to fully understand its potential alone.
