These products were chosen because they have been around for a while and they are still active in the cosmetic industry. For this reason, I am not going to review a product that's been discontinued. If you have a favorite product that I left out, please comment below and let me know why. Some of the products listed are new or are not yet in the cosmetic industry. The following products are recommended by the FDA to be taken with your food (see: Food Guide). If you don't have enough vitamins, minerals, and antioxidants, these supplements may not provide enough vitamins or minerals, which may result in poor complexion. Pomegranate and Cranberry juice can be taken as one of the many food sources. If you cannot tolerate this type of beverage, you may want to use a vitamin supplement. L-Theanine is a natural substance found in green tea that helps you sleep better. It can also help you wake up and relax. It may be the one vitamin that you need most to keep your skin clear and bright. I find that a teaspoon of tea leaves is enough to give you 5 to 10 grams of L-Theanine. You will have a good experience with L-Theanine if you try it at home, but I will say that a teaspoon will give you enough. You will need a glass to use it, and a spoon is fine as well.
