Here are a couple of videos on creatine.
I’ve been taking creatine for 5 years with great results. I’ve always taken 5 grams a day until recently after seeing a study about the cognitive benefits of taking 10-20 grams. I have had a good experience so far with the higher dose.
As always, do your own research and talk to your doctor.
I’m also sharing a few links to the brand of creatine I take and hydration packets.
Creatine ( these are the brands I use, you don’t have to use these)
Hydration electrolytes (make sure what you order is sugar free and under 10 calories)
