Apple cider vinegar is believed to lower blood pressure in animal studies, but WebMD warns that, as of 2014, the effects have not been fully studied. Whether apple cider vinegar can similarly affect the blood pressure in humans is unknown.

Because it is commonly sold as a food, there is no official dosage or use of apple cider vinegar, states WebMD. It is also available as a dehydrated pill. However, it should always be diluted heavily with water due to its acidity, which is high enough to harm tooth enamel and the esophagus. One to two tablespoons in a large glass of water taken with meals is generally sufficient.

Apple cider vinegar is also believed to affect weight loss, lower blood sugar and help with digestion, according to WebMD. However, its effect on weight loss is slight and, as of 2015, it is not sold as a weight loss aid. Apple cider vinegar is known to have an anti-glycemic effect that helps block some of the digestion of starch, which helps prevent spikes in blood sugar. Despite this, focusing on eating a healthy diet and overall wellness is more helpful than relying on apple cider vinegar as a fast cure.

Apple cider vinegar should not be taken by women with osteoporosis or people with diabetes, warns WebMD.
