If our bodies naturally contain creatine why should I spend time finding the best creatine supplement and spend money for it? Since creatine is also found naturally in fish like salmon and herring and also in red meat why is there a need for me to buy creatine supplements if I want to gain lean muscles? Our liver produces creatine naturally and creatine is stored in our muscles which becomes our source of energy. However the stored creatine in our muscles are consumed after 60 seconds of working out. This means that we need to resupply our bodies with more energy if we want to train harder and longer. This is where creatine supplements step in. Taking in creatine supplements will give the body a higher level of energy which will lead to being able to work out longer and endure more difficult routines. If you want to gain muscles you should be able to have high endurance.
