I don't know about the powder as far as calories/etc, but I have the caplets and won't take them--they are loaded with stuff I don't need--I save my calories for the good stuff--LOL. Plus, you have to take so many! I would say check the label then decide. If the calories, sugar, sodium, etc., aren't much it probably can't hurt. Just MHO. I added flaxseed oil caplets to my day for extra help.
