I've been eating protein shake, Vitamin B (which makes you less tired) & C (to help with your health). I've been having those for like 2 months and it's very obvious my face colour changed for the better and sometimes when I have pimples it heals a lot faster as well (I guess mainly from protein powder). Bear in mind I was a smoker and heave alcohol drinker before so it helps to clean my body heaps~ Can go to toilet a lot easier as well. Just becare when buying vitamins need to look for 100% natural ones. A number of people I know uses Nutrilite as they have their own organic farm in USA.
