Opt for the darker and roasted grain to help with the taste and you can add:
Cinnamon: Cinnamon is a natural stimulant that can help improve mood and focus.
Nutmeg: Nutmeg is another stimulating spice that can help improve concentration.
Ginger: Ginger is a thermogenic that can help speed up metabolism and increase energy.
If you choose cinnamon, pay attention! Pregnant or period women cannot consume!
I just thought about guarana powder... I’ve never tested it! Guarana gives a relatively similar energy!
