I'm not sure collagen helps my joints, but it is helping me lose weight. It makes me feel bloated and kills my appetite. I make a very high fiber smoothie with collagen, sometimes another protein powder like peanut, frozen berries, psyllium or acacia, kale, cocoa, almond milk and sweetener. It keeps me feeling full for hours and is pretty low in carbs and calories.

I've tried with whey powder but it doesn't work for me. I get hungry super fast.
