The first time I took creatine, it was mind-blowing. It felt like I was 10 years old again and had endless energy. All my lifts in the gym went up tremendously. The difference was so great that I had to check if I had the right weights, because it felt like someone had switched the plates. This was the initial reaction to creatine. Years later, when I started to take creatine again, I noticed no effect, so my conclusion was that in the first time I probably was deficient in creatine. Nowadays, I take it from time to time just to make sure that I don't get a deficiency.

This is definitely the best video I have ever watched on creatine. Thankyou for acknowledging all of these side effects and explaining the biochemical reactions so clearly, makes sense regarding bloating and digestion and especially hair loss. Creatine makes my muscles look great. I notice it helps my strength training a lot but unfortunately it causes hair loss so can’t take it for that reason!

I’m struggling with a chronic disease and just a few days ago discovered that exogenous creatine spares endogenous methyl groups. That is amazing that Felix provides so deep information! So glad to find this channel.

Thanks for mentioning insomnia. It's extremely rare that any influencers talk about this problem, but it is frequently discussed and dismissed at length in online forums. Also worth mentioning that the same studies are showing up to 1 in 3 people are creatine supplement non-responders so there's likely a ton of people wasting money on it, or suffering the side effects for no reason

Companies don't like to talk about mental side effects of anything.
