Most people can enjoy it freely, but there’s one small caution. Lemon’s acidity can wear down tooth enamel over time. Use a straw or rinse your mouth with plain water after drinking. If you have sensitive teeth, limit yourself to two glasses a day.
Also, if you have kidney issues, check with your doctor first—cucumber has potassium, which some folks need to monitor. But for the average person, it’s a wonderfully safe and gentle drink.
So go ahead. Slice, drop, and sip. Your body—and your taste buds—will send you a thank-you note.
