Summary:

There is little scientific study of the safety of apple cider vinegar. Apple cider vinegar (ACV) is prepared by pulverizing apples into a slurry of juice and pulp then adding yeast and sugars. Apple cider vinegar has been used alone and in combination with other agents for many health conditions. During the diet "craze" of the 1970s, it was suggested that a combination of apple cider, kelp, vitamin B6 and lecithin could "trick" the body's metabolism into burning fat faster. However, there is not enough scientific evidence to form a clear conclusion about the effectiveness of apple cider vinegar for any health condition.

Uses:

There are no scientific studies on the use of apple cider vinegar for medical conditions.

Safety:

Apple cider vinegar is likely safe when taken by mouth as food flavoring. Use caution if allergic or hypersensitive to apple cider vinegar or any of its ingredients (like apples and pectin). Use caution with a history of low potassium levels, diabetes or osteoporosis. Avoid if pregnant or breastfeeding.

Possible side effects:

Destroyed tooth enamel, decreased potassium levels.

Interactions:

	Note: Theoretical interactions are based on potential pH altering effects of apple cider vinegar. The degree to which apple cider vinegar affects blood pH is currently not established.
	Cardiac glycoside drugs like digoxin (like Lanoxin®), laxatives, diuretics like furosemid (like Lasix®), herbs and supplements with similar effects (like artichoke, elder flower, juniper berry, horsetail, celery, corn silk, chasteberry, rhubarb).

Dosing:

Adults (18 years and older):

	Note: No specific doses are supported by well-designed clinical studies.
	Colds: 2 tbsp cider vinegar has been taken in 1 cup water 3 times daily.
	Digestion aid: 285mg tablets have been taken with meals.
	High blood pressure: 2 tsp of apple cider vinegar mixed in water, has been taken in the morning.
	Vaginitis: 3 cups of apple cider vinegar has been added to a hot bath.
	Viral hepatitis (liver inflammation): A retention enema containing chlorophyll, water, and apple cider vinegar has been used. Safety and efficacy are unclear.
