Apple Cider Vinegar: From Health and Skin to Everyday Uses

Apple cider vinegar is no longer used only in cooking. It is now found in skincare routines, wellness drinks, hair care products and household cleaning cupboards. Its widespread use has also fuelled countless health claims, making it difficult to separate proven benefits from popular myths.

Apple cider vinegar (ACV) is made by fermenting crushed apples. During fermentation, the natural sugars are converted into alcohol and then into acetic acid, the compound responsible for its sharp taste and many of its studied effects. Unfiltered versions also contain a cloudy substance known as “the mother”, but most research focuses on the vinegar’s acetic acid rather than the mother itself.

Research has mainly focused on ACV’s effect on blood sugar after meals. Some studies suggest that drinking diluted apple cider vinegar with a meal may help reduce the rise in blood glucose after eating carbohydrates. Researchers believe acetic acid may slow stomach emptying and improve the body’s response to insulin. While these findings are encouraging, ACV is not a treatment for diabetes, and anyone taking blood sugar lowering medication should speak to a healthcare professional before using it regularly.

Many people also use apple cider vinegar to support weight management. Some research suggests it may increase feelings of fullness, which could reduce calorie intake, but the effect is modest. It should be viewed as one part of a balanced lifestyle, not a shortcut to losing weight.

Skincare is another area where apple cider vinegar attracts attention. Because it is acidic and has mild antimicrobial properties, some people use it as a toner or spot treatment. However, dermatologists warn against applying undiluted apple cider vinegar directly to the skin. It can cause irritation and, in some cases, chemical burns. If used at all, it should be well diluted and patch tested first. People with eczema, rosacea or sensitive skin should be especially cautious.

Apple cider vinegar has also become a popular hair rinse. A diluted rinse may help remove product build up and leave hair looking smoother. However, it cannot repair damaged hair, prevent hair loss or change hair texture. Using it too often may dry out the hair and irritate the scalp, so occasional use is generally enough.

Its usefulness extends beyond personal care. Apple cider vinegar adds flavour to salad dressings and marinades, helps neutralise some household odours and can be used to clean certain non stone surfaces. It should not be used on marble, granite or other natural stone because the acid can damage these materials.

Despite its popularity, there are common mistakes to avoid. Drinking undiluted apple cider vinegar can erode tooth enamel and irritate the throat and oesophagus. Taking large amounts may also cause digestive discomfort and contribute to low potassium levels in some people. Using a straw and rinsing the mouth with water afterwards may help reduce contact with teeth.

For most healthy adults, experts generally recommend limiting intake to one or two tablespoons diluted in a large glass of water, preferably with a meal. People with diabetes, chronic kidney disease, stomach ulcers, severe acid reflux or those taking insulin, diuretics or certain heart medications should seek medical advice before making it a regular part of their routine.

Apple cider vinegar has both proven uses and clear limitations. Current research supports modest blood sugar benefits, while evidence for many other claims remains limited. Used sensibly, it can be a useful kitchen ingredient with a few evidence backed health applications and practical household uses. It should not be seen as a cure all, but it can still earn a place in everyday life when used safely.
