From Glycergrow write up:
Why are there calories and fat in GlycerGrow(TM) whereas other glycerol (or Glycerol MonoStearate) products do not mention calories or fat on their labels?
Good question. As far as the FDA is concerned, glycerol is a carbohydrate and stearic acid is a saturated fatty acid. Therefore, Glycerol MonoStearate has both fat and carbohydrates in it, which both result in calories. But you have heard that saturated fat is bad for your cholesterol? True, in most cases, but not with stearic acid. Stearic acid is one of the only saturated fatty acids that actually have a neutral or cholesterol-lowering effect on serum cholesterol levels in human studies.
--don't know if this answers your question lol
