So I was doing some research about what are the vitamins that the body produces and the other ones that the human body does not produce and this is a short list of the vitamins that the human body doesn't produce. So vitamin C, vitamin D, vitamin E, vitamin K, folate, calcium, iron, magnesium, potassium, zinc. Well it's important to consume these essential vitamins and minerals through a balanced and varied diet. Some people would like to you know buy some pills or they do take it from natural food as well.
