Apple cider vinegar (ACV) is widely considered safe for daily consumption. Most research suggests a recommended dose of about one to two tablespoons, typically diluted in water.
Understanding Apple Cider Vinegar
ACV is a type of vinegar derived from fermented apple juice. Often used as a natural flavor enhancer or preservative, it is a common ingredient in various foods. Beyond culinary purposes, many people choose to drink it for potential health benefits. Scientific research has explored these benefits, leading to widespread interest in its medicinal use.
This article delves into the science behind ACV’s potential advantages. It also outlines recommended dosages, possible risks, and side effects associated with its consumption.
Is Daily Consumption Safe?
For most people, adding ACV to their daily diet poses no significant risk. It is frequently found in salad dressings, marinades, and other condiments.
However, questions arise regarding potential risks when consumed in larger amounts. While research on the long-term effects of high ACV consumption is limited, experts agree that drinking it undiluted or applying it directly to the skin can cause adverse effects. Moderation is key to safely incorporating ACV into daily routines.
Recommended Dosage for Various Conditions
The health benefits of ACV are largely attributed to its main active compound, acetic acid. A 2016 review suggested that consuming around 15 milliliters (one tablespoon) of acetic acid per day may be sufficient to experience its benefits. However, the ideal dosage varies depending on the specific health concern being addressed.
Before significantly increasing ACV intake, it is advisable to consult a healthcare professional. Certain individuals may need to exercise caution due to potential interactions with medications.
Blood Glucose Control
Research indicates that vinegar consumption may help regulate blood glucose and insulin levels. A 2017 review found that individuals who consumed vinegar had lower glucose and insulin levels after meals, regardless of whether they had existing blood sugar disorders.
A separate 2004 study observed that ACV improved post-meal insulin sensitivity in individuals with insulin resistance. Researchers suggested that acetic acid might have effects similar to diabetes medications like acarbose and metformin.
A commonly used ACV recipe for blood glucose control consists of:
- 20 grams of apple cider vinegar
- 40 grams of water
- 1 teaspoon of sugar or sweetener
These findings suggest that ACV may influence glucose regulation. However, individuals with diabetes or blood sugar concerns should seek medical advice before incorporating ACV into their routine. It should never replace prescribed medications.
Weight Management
Several studies have examined the impact of vinegar on weight loss. In 2014, researchers explored its effects on obesity-related factors, including body weight, fat mass, and lipid levels. Participants were divided into three groups, each consuming a 250-milliliter beverage twice daily, with varying amounts of ACV (0 ml, 15 ml, or 30 ml). Those who consumed ACV experienced modest weight loss (1–2 kg) over three months, along with reductions in fat mass and lipid levels.
A 2018 study involving 44 overweight and obese individuals further investigated ACV’s role in weight management. Participants followed a calorie-restricted diet, with some consuming 15 milliliters of ACV twice daily. Those who included ACV in their diet saw additional benefits such as reduced body weight, BMI, visceral fat, hip circumference, appetite, and cholesterol levels.
The findings suggest that combining a healthy diet with ACV may enhance weight loss efforts. However, further research with larger participant groups is necessary to confirm these effects.
Polycystic Ovary Syndrome (PCOS)
PCOS is a condition that affects ovarian function and often leads to irregular menstruation and fertility challenges. Research suggests that insulin resistance may contribute to PCOS development in some individuals.
A 2013 study examined ACV’s potential role in managing PCOS. Seven participants consumed a beverage containing 15 grams of ACV daily for approximately three months. At the end of the study, six individuals showed improved insulin sensitivity, and four experienced more regular menstrual cycles.
The results indicate that ACV may support ovarian function by enhancing insulin sensitivity. However, further research is necessary to validate these findings.
Potential Side Effects
While ACV is associated with various health benefits, it also presents certain risks. The primary concerns include skin irritation and dental enamel erosion.
Skin Irritation
Dermatologists caution against applying undiluted ACV directly to the skin, as it may cause irritation or burns. To minimize this risk, it should always be diluted with water or oil before topical application. Conducting a patch test on a small area of skin is advisable before widespread use.
Tooth Enamel Erosion
Dentists warn that the acidity in ACV can weaken tooth enamel over time. Consuming highly concentrated ACV or using it long-term increases this risk. To protect dental health, ACV should be diluted in water before drinking. Rinsing the mouth with plain water or mouthwash afterward may further help reduce the impact on enamel.

Drug Interactions
ACV has the potential to interact with certain medications, including diuretics and diabetes drugs. Individuals taking prescription medications should consult a healthcare provider before incorporating ACV into their diet.
In cases where ACV supplementation is unsuitable, medical professionals may suggest alternative approaches to achieve similar health benefits.
Final Thoughts
Research suggests that ACV may contribute to blood glucose regulation, weight management, and PCOS treatment. While it offers potential health benefits, it is essential to consume it in moderation and be mindful of potential side effects.
A daily dose of one to two tablespoons, diluted in water, is generally safe. However, specific dosage recommendations depend on individual health goals. Long-term consumption may increase the risk of enamel erosion, and interactions with certain medications should be considered.
Before making ACV a part of a health regimen, it is important to evaluate personal health conditions, dietary habits, and medical history. Consulting a healthcare provider can help determine if ACV is an appropriate supplement and how best to incorporate it. While ACV is not a cure-all, when used appropriately, it can be a valuable addition to a balanced and healthy lifestyle. As with any supplement, consistency, moderation, and informed usage are key to maximizing its benefits while minimizing risks.
