I was gonna write: I don't think so, it help to strengthen the adrenal glands. Until I found this article>>>Please read.
But I found this article on Livestrong.com and it states:
Pantothenic acid, also known as vitamin B5, is a pro-hormone essential vitamin for the production of cortisol in your body. During cellular metabolism, your body converts carbohydrates into acetyl co-enzyme A, which is used for the production of lipids such as cholesterol and other adrenal hormones including cortisol, notes The World's Healthiest Food website. Precursor compounds such as cholesterol are essential for the synthesis of cortisol and are depleted during periods of stress. Vitamin B5 is converted into an intermediary compound known as pantothene, which acts as a precursor for acetyl-coenzyme A and is eventually used for the production of cholesterol and cortisol. If you are suffering from adrenal fatigue, you are recommended to take 600 to 1200 mg of vitamin B5 a day.
