Following a search around the web, it appears that the suggested intake for potential health benefits is 1-2 tablespoons daily, diluted. Undiluted apple cider vinegar has 5% acetic acid content. That is acidic! Take it diluted in water and use a straw to help avoid the risks associated with taking it neat. Taking it neat will likely erode your tooth enamel and may cause burns to your oesophagus. I think the best way to use it is on your food, perhaps as a salad dressing, a salt substitute, or roasting your vegetables. Disclaimer: I am not a medical expert; I am a chef!
