@Bradley_JF Not in any practical sense, potassium in any form strong enough to actually be effective as a vitamin requires a prescription and the pills are horse pills that youd need. This all assumes you just need to replace the difference, but if cannabis is acting as a diuretic you may need to have an even higher dose to balance it out, assume you can at all (it is possible and likely that cannabis effect would cause any additional potassium you consume to be lost as well, as that is usually how diuretics work).

@freemo @Bradley_JF I remember training in the humid heat of the deep south. We would usually have to carb load, eat a bunch of bananas and take more supplements on the way. It never seemed to do more than postpone the inevitable heat cramps.
