The Blue Salt Trick recipe can also be paired with a splash of lemon for those who want added flavor or digestive benefits. Lemon introduces vitamin C and natural antioxidants, making the drink feel lighter and more refreshing. While the classic recipe uses only salt and water, the lemon variation is popular among people who find plain salty water challenging to drink. The citrus also helps stimulate saliva production, which can further improve digestion. Blue salt trick recipe
