What is NAFLD and why should you care?
Non-Alcoholic Fatty Liver Disease (NAFLD) happens when fat builds up in your liver, without heavy drinking being the cause. It’s often linked to being overweight, diabetic, or having a sluggish metabolism. If not managed early, NAFLD can progress to more serious stages like NASH (inflammation), fibrosis, cirrhosis, or even liver cancer.
This has led many to turn to home remedies, ACV being one of the most popular. But does it really help your liver?
What does research say about Apple Cider Vinegar?
Apple cider vinegar is made by fermenting apple juice into alcohol, and then into acetic acid, the compound responsible for its sharp taste and supposed health perks.
It’s often marketed as a metabolism booster, fat burner, and blood sugar regulator. Some claim it can reduce liver fat and support liver function. But what does science actually say?
Animal studies suggest it might help
A 2025 study on rainbow trout with NAFLD, as reported by TOI, found that a 2% ACV mix reduced liver fat (steatosis), triglycerides, and key liver enzymes like ALT and AST. But here’s the twist, when the dose was doubled to 4%, the condition worsened.Another set of studies on rodents fed high-fat diets showed similar findings. ACV helped reduce liver fat, improve insulin resistance, and lower glucose levels. In one experiment, liver fat levels dropped from 56% to 20%.Researchers believe acetic acid may promote fat-burning and ease metabolic stress. However, all these results come from animal studies, not humans.
And what about human trials?
Human-based research is still limited. A 2021 review, quoted by TOI, suggested ACV could lower cholesterol and fasting blood sugar, both helpful for those with NAFLD. But there’s no strong proof yet of a direct impact on liver fat in humans.
In short: promising, but far from conclusive.
ACV: Worth a shot or not?
Possible perks
- May support blood sugar and fat metabolism
- Could assist in weight loss when used with diet and exercise
- Might improve some metabolic markers over time
But here’s the catch
- Too much ACV can damage tooth enamel, cause low potassium, and upset your stomach
- It may interact badly with diabetes or blood pressure medications
- Most experts advise no more than 1–2 tablespoons a day, diluted in water
Health professionals, as quoted by TOI, warn against treating ACV as a “cure”. It’s a supplement, not a substitute for actual medical treatment or lifestyle changes.
How to use ACV the safe way
- Use raw, unfiltered ACV (look for “the mother”)
- Dilute properly: Mix 1 tablespoon in a full glass of water
- Drink after meals to avoid acid reflux
- Rinse your mouth or use a straw to protect your teeth
- Watch for side effects like bloating or discomfort
- Talk to your doctor if you’re on any medication
ACV isn’t a magic potion
While ACV may offer some small benefits for metabolism, it’s not a cure-all for fatty liver. The best way to reverse NAFLD is through a balanced diet, regular exercise, and guidance from your healthcare provider. Apple cider vinegar might play a supporting role, but it’s definitely not the hero of the story.
