Supplements are just that…supplements. It means you can take all of your vitamins and other nutritional calories from regular food. For example, creatine is nothing new to the world of sports. Back in ancient Greece it was well known among the athletes and elite soldiers that red meat was the source of some extra nutritional value because it help them build more muscle and increase their strength and stamina (even though they didn’t know what creatine was back then). I strongly suggest to my clients to avoid supplements unless it has been prescribed by their dietitian or physician. The same goes for vitamins, unless there is a deficiency in your diet and/or body, there is really no need to spend all that extra money to buy something which you either don’t need or you can get it form a better diet.
