Why huberman drinks mate?

Huberman drinks yerba mate for alertness, potential health benefits, and its taste.

• Caffeine and alertness: He says mate is a strong caffeinated tea that helps stimulate the brain and support alertness and focus, much like coffee. 1
• GLP-1 and appetite: Mate may increase GLP-1, which can suppress appetite; he says appetite suppression is not his goal, though it helps him extend his morning fast. 2
• Other potential benefits: He points to its electrolytes, which matter for nervous-system function, and mentions possible benefits involving blood-sugar regulation, digestion, antioxidants, and neuroprotection. 3 4
• Flavor and brewing: He says he enjoys mate’s taste. To make it less bitter, he recommends water just below boiling rather than boiling-hot water. 5 6
