whats the difference between creatine and Protein? do you need to be a certain age to buy either?

Creatine is a naturally formed amino acid that is found in the human body. The human body produces creatine partly from the foods you eat such as meats, and partly on the body itself. Creatine boosts anaerobic energy in the body. It provides instant energy to the human body. Creatine makes the muscle suitable for high-intesity, short duration exertion like weightlifting or sprinting. Side-effects of creatine include; dehydration, muscle cramps, nausea, diarrhea, and gastrointestinal distress. Although while on creatine you can prevent dehydration by drinking liquids constantly. Generally, creatine products say "do not take until your 18." But i recommend around 14-16 is a good age to start supplementing with creatine. Creatine could possibly increase your performance on the paintball field also.

Protein on the other hand is used several different ways in the body. The body uses protein for hormones, enzymes and other essential chemical controlling substance. There are also several different kinds of protein, most people use whey. And some people use Casein protein. Both of which are good sources of protein. The difference between the two is that whey is more of a fast and easily absorbed protein, and Casein on the other hand is more of a slow acting absorbed protein. Personally, i just stick to whey. Anyways, basically protein is the building blocks of your muscles. After a workout, protein repairs the damaged muscles and increases recovery time. Without a high protein diet, your chances of getting a lean and muscular body are significantly low. But there you have it .

Edit: Generally at Supplement stores such as GNC, you have to be 18 to buy creatine or have an adult with you. With protein supplements, they usually let anyone of any age buy protein. With to a certain extent anyway.

GNC does not have any age limits on creatine, nor have they ever. Some franchises may impose their own restrictions, but most GNC's are corporate, and a friend assured me that the corporate ones do not and have not had age restrictions on creatine.
