Do anybody here is familiar with brands like Taraqui,Union,Canarias or Kraus?(Guayaki here not exist at all)
They are all yerba mate brands,my favourited btw.
Im talking about traditionally brewed yerba,not some diet suplements.
Mixture of koffeine and vitamins in yerba mate is very unique,and also very useful for any workout.
Drinking it somehow erase sense of hunger.
But it's very sweaty bussines-proper headband(and wrist bands+lots of chalk) is very needed.
In my case,at least.
