I recently started taking a collagen drink which has many other vitamins and supplements. i feel great but my concern is that after i take the drink i totally forget about food for the whole day. is this normal or should i be concerned?

Collagen is the most abundant protein in the body involved in the formation of bone, cartilage, muscles, tendons and even the largest organ in the body, the Skin. Because of it's fiber-like structure it tends to swell and give the sense of fullness. One should pay attention to having enough calories from the major food groups- Carbohydrate, Fat & Protein- before having a collagen drink.
