Soak up sweat. If baking soda can keep the fridge from reeking, it can do the same for you. Sodium bicarbonate sucks up moisture and “helps stop bacteria from thriving.” Sprinkle a “small amount onto your hands,” then apply directly to underarms.
Think zinc. This mineral helps keep “bacteria in check.” Take about “30 milligrams in supplement form” daily or “up your intake of food sources like shellfish and legumes.” Zinc can exacerbate copper deficiencies, so also take “1 milligram copper” via a multivitamin.
Lather on the oil. “Packed with antibacterial compounds,” tea tree oil can work as a “potent” natural antiperspirant. Mix a few drops with “a teaspoon of almond oil” and rub onto armpits. If you have sensitive skin, perform a “patch test on the inside of your forearm” first.
