The human body naturally produces creatine. Though there is a benefit to supplementation as it doesn’t produce the optimal amount.
Also creatine is good for more than just bodybuilding too! Solid supplement.
Im always tiring to have a evolutionary approach on such questions.
Why should our body produce less creatine when more is better. Our body produces creatine in liver and kidneys but also takes creatine from nutrition. If we get more creatine from nutrition, our body regulates the production down. Why should our bodies do that if more would be beneficial.
From an evolutionary standpoint this doesn’t make any sense.
We make ATP just fine, theres 3 mechanisms for make ATP: aerobic glycolysis (that requires breathing, uses carbs, fats and protein when needed), anaerobic glycolysis (without the need of air, using carbs mainly) and creatine Phosphate (take a guess as to that fuel source). These all work together but have their own special areas aerobic works best long distance and endurance, Anaerobic is best in your weight lifting and creatine is great in short burst movements like Olympic lifting.
we make creatine and store creatine from animal protein (studies have proven you will very likely be creatine deficient on a vegan diet… go figure). We did discover that we can essentially shunt more creatine into our stores by consuming it as a straight chemical, this removes the needs for synthesis and extraction from animal foods. Now as for the evolution, we actually kinda suck ass about creating our own creatine. Most of other animals on our level of the food chain can store and make it better, but it’s not a big deal.
I’ve had plenty of creatine fueled sessions and plenty of non-creatine sessions and I found it to be pretty useless in the end game. However, that is my opinion and experience, which I would knock down to my diet just being higher quality and more consistent. Try it for yourself, see how you feel.
I will say many like to contribute their gains to creatine, but this isn’t necessarily true. Some also forget to factor in that you do retain water within the muscle as creatine is a waterphilic thing.
