1. Vitamin C
I'm not really a fan of vitamins, but I'm a fan of Vitamin C. You can get vitamin C by eating more oranges and other citrus fruits. If you buy Vitamin C from a store, it is usually in a bottle that has a little label in it. The label states that Vitamin C is very high in Vitamin A, and not recommended for children. Vitamin C also has the best claim to being a powerful antioxidant. This is a very important vitamin for everyone, because it is necessary for maintaining a healthy immune system. Many people say that a lack of Vitamin C can be the cause of many common illnesses. Vitamin D
Most people think that vitamin D comes from animals. It actually comes from the skin of sun-exposed people. A lack of vitamin D is the best cause of most of the diseases of adults, but it is very important for children and young people. The best thing you can do is to get a daily dose of vitamin D for at least three months in the summer. Some doctors say you should also take vitamin D supplements at least every four weeks, but that is just a personal opinion.
