I stole this from another website.. Like I said before.. I could not recall the dosage..but I remember it was pretty high..
The Adequate Intake for pantothenic acid has been set at 5 mg daily, and this is usually met through the diet, but this dose is miniscule compared to supplemental dosages. The dosage most commonly used to treat acne is 5 g daily, although it can go as high as 15-20 g daily. Sometimes a loading phase is employed followed by a smaller dose. For most other purposes the dose is much lower. 1 g of pantothenic acid along with 3 g of vitamin C improved wound healing. For general health, the recommendation is 100-500 mg daily. One report classified pantothenic acid as a category C nutrient, meaning it was harmless at doses far exceeding the RDA. Those who take large doses (10-20 g) for acne treatment commonly report diarrhea and occasionally heartburn or nausea. No serious adverse effects have been reported in this dosage range. Pantothenic acid exhibits synergistic effects with vitamins C, B6, and B12, and can improve utilization and may correct deficiency of these vitamins.
