I do recall reading up on them a while ago after someone asked or I was talking to someone about them but I only vaguely recall feeling sceptical but I can't tell you why as I don't remember.

I was on that website earlier, they have some nootropics I want to buy

They help with memory, learning etc

SM, I bought some with my nootropics to see if they help with metabolising fatty acids. So far I have been very constipated and a constant rash in my arm pits.

Ketosis gives me a rash too and antihistamines etc don't help it. It is listed as a side effect of ketogenic diets but I am yet to meet someone else who gets it. Usually the first place I get it is under the boobs which can be unbearable!

I tried them. First off they have nothing to do with ketosis.

They are meant to make you warmer therefore increasing your RMR, I took them, the first time I felt warmer, but I have kind of gotten used to them now, and I am always warm after eating more fat and less carbs.

I don't think a supplement can really help much, some people have negative effects to them, and if you pay doctor Oz money he will say anything is good!
