Apple cider vinegar (often called ACV) is a popular natural product made from fermented apples. People have used it for many years in cooking and as a home remedy. Today, many people drink it or add it to food because they think it helps with health. But what does science really say? In this article, we look at the real benefits of apple cider vinegar based on studies, how to use it safely, and easy ways to add it to your day. We focus on facts from trusted sources like health experts and research, so you get clear and honest information.
What Is Apple Cider Vinegar?
Apple cider vinegar starts with apple juice. Yeast turns the sugar in the juice into alcohol. Then, bacteria turn the alcohol into acetic acid. This gives ACV its strong sour taste and smell. Raw, unfiltered ACV has a cloudy part called “the mother.” This is made of good bacteria and enzymes. Many people like this type because it may have extra benefits.
ACV has acetic acid as the main part. It also has small amounts of vitamins, minerals, and plant compounds like polyphenols. These may help the body in some ways. But ACV is not a magic cure. It works best as part of a healthy life with good food and exercise.
Key Health Benefits Backed by Research
Many claims about ACV come from old stories or small tests. But some benefits have support from studies. Here are the main ones that science shows most clearly.
Helps Control Blood Sugar Levels One of the strongest benefits is for blood sugar. Studies show that ACV can lower blood sugar after meals. It may slow how fast food leaves the stomach and how the body takes in carbs. This leads to smaller rises in blood sugar.
For people with type 2 diabetes, drinking diluted ACV can reduce fasting blood sugar and HbA1c (a measure of average blood sugar over months). A review of studies found it lowered fasting blood sugar by about 8 mg/dL in people with higher levels. Other research from recent years shows similar results, like reductions in blood sugar and better insulin use in people with diabetes.
This does not replace medicine or doctor advice. But it can be a small help when used with healthy eating.
May Support Weight Loss in a Small Way Some studies link ACV to modest weight loss. In one test, people who took 1-2 tablespoons daily with a low-calorie diet lost a few extra pounds over weeks. A 2024 study and reviews found that daily ACV (around 15-30 mL) for 4-12 weeks reduced body weight, BMI, and waist size in people with overweight or obesity.
It may work by making you feel full longer, lowering appetite, or helping the body use fat better. But the weight loss is small—not dramatic. It works best with diet changes and activity. Experts say more big studies are needed, and one popular study was retracted due to issues. So, see it as a helper, not the main way to lose weight.
Can Improve Cholesterol and Heart Health Markers Some research shows ACV may lower total cholesterol, triglycerides (bad fats), and improve good cholesterol in people with high levels or diabetes. Reviews of trials found small drops in cholesterol after regular use.
This may come from acetic acid and plant compounds that fight inflammation and help fat use. But results vary, and it is not a replacement for heart medicine.
Other Possible Benefits
- Kills Some Harmful Bacteria: Acetic acid can fight germs. This is why people use it to preserve food or clean.
- May Help Digestion: Some feel less bloating or better gut health, but proof is limited.
- Antioxidant Effects: The polyphenols may reduce cell damage from stress.
Many other claims—like curing cancer, detoxing the body, or fixing skin problems—lack strong proof. Always check with a doctor before using it for health issues.
Common Uses of Apple Cider Vinegar
People use ACV in many ways beyond drinking.
In Cooking
- Make salad dressings: Mix ACV with oil, honey, mustard, salt, and pepper.
- Marinades for meat or veggies: It adds flavor and tenderizes.
- Pickling: Use it to make quick pickles of cucumbers, onions, or carrots.
- Sauces and soups: Add a splash for tang.
As a Home Remedy
- For hair: Rinse with diluted ACV after shampoo to make hair shiny (use once a week).
- For skin: Some dab diluted ACV on spots, but test first—it can irritate.
- Cleaning: Mix with water to clean surfaces (not for health drinking).
Always choose raw, unfiltered ACV with the mother for possible extra benefits.
Simple Ways to Add Apple Cider Vinegar to Your Daily Routine
Start small to see how your body reacts. Most experts suggest 1-2 tablespoons (15-30 mL) per day, diluted. Never drink it straight—it is too acidic and can hurt teeth or throat.
Here are easy ideas:
- Morning Drink Mix 1 tablespoon ACV in a big glass of warm water. Add honey or lemon for taste. Drink before breakfast. Some take it before bed too.
- Before Meals Drink diluted ACV 10-20 minutes before eating carbs. This may help blood sugar stay steady.
- In Tea or Juice Add 1 teaspoon to herbal tea or apple juice. It hides the sour taste.
- Salad Every Day Use ACV-based dressing on lunch or dinner salad. This is tasty and safe.
- Smoothie Boost Add a small amount to fruit smoothies with banana or berries to balance the sour.
- Sparkling Water Mix Mix 1 teaspoon in sparkling water with fruit slices for a refreshing drink.
Tips for Best Results
- Use a straw to protect teeth.
- Rinse mouth with water after.
- Start with 1 teaspoon and build up.
- Buy good quality ACV—organic if possible.
Safety, Side Effects, and Precautions
ACV is safe for most people in small amounts. But it is acidic, so watch out.
Possible Side Effects
- Tooth enamel damage: Always dilute and use a straw.
- Throat or stomach irritation: Do not drink undiluted. It may worsen acid reflux or slow stomach emptying.
- Low potassium: Long-term large amounts may lower it.
- Nausea or indigestion: Some feel sick if taken on empty stomach.
Who Should Be Careful?
- People with diabetes: It may change blood sugar—check with doctor.
- Those on medicines: It can interact with diuretics, insulin, or others.
- Kidney problems: High acid may affect.
- Pregnant or breastfeeding: Talk to doctor first.
If you have health issues, ask a doctor before starting daily use. Stop if you feel bad.

Final Thoughts
Apple cider vinegar is a simple, cheap addition to daily life. Science supports some benefits—like better blood sugar control, small help with weight, and possible cholesterol improvements—especially for people with diabetes or overweight. But it is not a cure-all. The effects are modest and work best with healthy habits.
Try it in food or diluted drinks for taste and possible perks. Listen to your body and talk to a health expert for personal advice. With care, ACV can be a nice part of a balanced routine.
