Greetings for the day!!     Taking apple cider vinegar alongside a calorie restricted diet can help people with overweight reduce their weight. The best time to take apple cider vinegar is after a meal (20min) or on empty stomach. 10-15ml per day diluted and taken 2 or 3 times a day is best.    Apple cider vinegar is typically safe, but it may have side effects or disadvantages for some people. The acidity of apple cider vinegar may wear away tooth enamel, especially if a person consumes it undiluted. For this reason, it is a good idea to dilute apple cider vinegar in food or drink. A person may also wish to use a straw to drink it or to clean their teeth afterward. Other potential side effects and interactions include: nausea worsened acid reflux altering insulin levels worsening low potassium levels Apple cider vinegar can also overburden the kidneys if people have a chronic kidney condition. If a person has a preexisting health condition or takes any medication, they should consult a doctor before trying apple cider vinegar.
