The best time to drink apple cider vinegar (and when you should not)

Apple cider vinegar (ACV) has become a popular home remedy known for its potential health benefits, from aiding weight loss to stabilizing blood sugar levels. But like most supplements, timing matters.

When and how you take ACV can make a difference in its effectiveness and in avoiding unwanted side effects.

What is Apple cider vinegar?

Apple cider vinegar is made by fermenting the sugars in apples into acetic acid — the primary active ingredient responsible for its sour taste and health benefits. ACV comes in two main forms- filtered and unfiltered. Sometimes, other fruits such as raspberries are added to create flavored versions, but the base remains apple.
