if there's a strong measurable effect to any of these supplements, why can't it be studied? there are companies on both sides, so someone who sells creatine could fund one if they like.
There is an incredible amount of evidence for creatine being beneficial for making you stronger/muscle growth. Which is probably the primary reason it's sold. So it's not as if it's not studied or there are no known effects of supplements.
> Magnesium? Its widely known that magnesium is used by the body lol
Who disputed this?
> What they “doubt” is that it can be absorbed through the skin
The science is helpful. Magnesium sulfate is absorbed less effectively than magnesium chloride. Of course, you're not eating the amount of Epsom salts one dumps in a bath.
> And it is studied btw - problem is there are countless on both sides
Drinking the same Epsom salt in water that you soak in has the same effect as soaking in hot or cold water with it, and it's also the same effect as taking magnesium supplements sold over the counter.
You can try it yourself - totally safe. You already eat magnesium all the time.
Whatever you're doing with your comment, I'm not convinced.
