ACV is highly acidic, and drinking it undiluted could potentially harm your tooth enamel and irritate your throat. Mixing ACV with water helps reduce its acidity, making it gentler on your digestive system and minimizing the risk of any discomfort. Additionally, dilution can make it more palatable, as ACV's strong taste can be overpowering on its own. Remember, moderation is key, and if you have any concerns or underlying health conditions, it's wise to consult a healthcare professional before making it a regular part of your routine.
