Is it true that creatine should be taken with carbs such as grape juice for better absorption?
Not sure if this has been studied but I've noticed a positive correlation in creatine supplementation and acne breakouts in myself. Without fail, it happens everytime and then a few weeks to a month after I stop supplementing creatine, my skin clears up again.
Again, not saying this is true or even cause-and-effect but more of an observational correlation that I've noticed over the years.
I get my VO2 max checked twice a year at work. When I started taking creatine my VO2 dropped about 4 points. It was like this for about 2 years. I stopped taking creatine (no real reason, I just ran out and didn't buy anymore) and my VO2 went back up. The physiologist said that creatine can cause your blood pressure to go up slightly as well as resting heart rate which will affect VO2 max.
Have you noticed anything like this? Looking back through my records it showed my BP and RHR were a little elevated during the time I was on creatine.
