Creatine uptake enhances antitumor immunity

    This is such a crazy substance. I'm 43 and I feel like I have more energy than I have ever had before. I started taking it during recovery from a bad ankle fracture since it helps building muscle mass. Once the ankle was better I took up CrossFit, and kept on taking creatine because why not, it helps replenish ATP so I will be able to give the extra-push when working out, I thought.

    What is blowing my mind though is that at $dayjob my team is going through a crazy crunch to deliver a very strategic project and some of us are pushing 10-12h days often. I'm in hour 12 today for the second day in a row, and my head is not tired at all. Turns out the brain also uses a lot of ATP too, specially during demanding cognitive tasks so I guess it is creatine that is keeping the engine running smoothly even after so many hours.

    I will like once every week or two have a poor night sleep. These days I take twice the dose and I don't feel like I'm sleep deprived at all. Feels like cheating! And apparently no side effects at all so far. Well, maybe I'm working too much.

      It has an especially noticeable effect if you're a vegetarian. I'm a lifelong vegetarian, and high doses of it for me are a crazy cognitive enhancer.

        That's because creatine is missing in vegetarian diets. It is found in beef. Something to consider if you are thinking about going vegetarian.

          There's 0.5 g of creatine per 4 ounces of red meat.

          That's pretty insignificant. Does anyone really wanna eat 2.5lbs of beef every day for the usual dose of 5g?

            Yes, but I probably shouldn’t.
