Which nootropic is the best for increasing glucose metabolism?

dinitrophenol

low catecholamines = lower metabolism.

I can see it.

So instead of nootropics, you probably want to increase catecholamines and adrenergic receptors stimulants.

Norepinephrine/epinephrine can be increase by several different supplements : Raspberry Ketones, octopamine, yohimbine.

There are several adrenergic receptors.
Alpha 1 agonist : (vasoconstriction) psudophedrine, phenylephrine, synephrine

Alpha 2 antagonist : (increase norepinephrine + helps stubborn subcutaneous fat) yohimbine, theacrine, testosterone

Beta 1: (increases BP) higenamine

Beta 2: (brochodialator, increases insulin, muscle relaxation) methylsynephrine, ephedrine, clenbuterol, hordenine

Beta 3: ( increases lipolysis in brown fat) octopamine

But here's the thing. This doesn't lower blood sugar.
This increases lipolysis= fat burning.

If you need to lower blood sugar, this won't help. Watch reddit reviews for additional help

Fish oil, Panax Ginseng, Chromium are the best nootropics increasing glucose metabolism. Kinder Berberine is probably the strongest tho.
