Fatty Liver and Garlic: Should You Avoid It or Eat More?

I grew up hearing two conflicting ideas: garlic is fantastic for overall health, but it can also damage your liver. It’s not uncommon to hear others make the same contradictory declarations.

So when I was diagnosed with fatty liver disease (NAFLD) in 2014, those mixed messages turned into real anxiety. My first instinct was to remove garlic from my diet entirely. But since then, I reversed my fatty liver and learned a lot of new things along the way – including interesting things about garlic.

I met people online (on the Fatty Liver Support Group) who were still eating garlic daily – without any apparent setbacks. This led me on a path of digging up research and personal experiences that changed my perspective forever.

One of these studies, conducted recently in Mexico, noted that alliin, a fresh sulfoxide that’s a natural component in fresh garlic, reduced inflammation markers and improved metabolic parameters without affecting others.

While the study has been conducted on mice only, it tells that garlic (through its alliin) has the potential to reduce inflammation – including that of the liver.

Another study – this time conducted in 2006 and also in mice – found that high and very high dosages of garlic homogenate (above 1 gram per kilogram) resulted in liver damage and a deterioration in liver function tests.

However, the same study found that lower doses of up to 0.25 grams per kilogram caused no liver damage. Unfortunately, the people conducting the study did not test for potential benefits.

For an adult weighing 70 kilograms (154 pounds), 0.25 grams per kilogram would mean around 17.5 grams of garlic daily. A single clove typically weighs about 3 grams, so even six cloves a day stayed in the safer range, based on that study.

So at least from this point of view, the study would conclude that eating 1-2 cloves each day shouldn’t be harmful.

Does this mean that garlic is good for fatty liver disease?

This is the tricky part: real human studies that specifically link garlic to improvements (or harms) in NAFLD are hard to come by.

We do have general research (rounded up here) suggesting that garlic has antioxidants, antibiotic, and antifungal properties and that it’s loaded with compounds like the aforementioned allium, ajoene, arginine and selenium, which may help the liver.

Experts often agree that garlic, consumed in moderation, can be part of a healthy diet. But going from “it requires massive amounts to cause damage” to “it’s automatically great for liver health” is still a big leap.

Arginine and selenium are mainly known to help the liver detox, as well as lower blood pressure in the liver.

But in conclusion, I couldn’t find anything that proved garlic cures or significantly helps reverse fatty liver disease in people.

At the same time, we have unconfirmed claims that it is overall healthy so, as long as we don’t overdo it, we can add it to some meals.

Tips for Using Garlic Safely

If in doubt, consult a doctor or a dietitian. They can offer personalized advice that factors in your unique health background – this is always the most important step to follow. Apart from this, here are a few things to consider when it comes to garlic and NAFLD/MASLD:

Moderation is Key
If you’re eating a few cloves here and there, you’re probably well under the amount that caused harm in mouse experiments and still getting benefits from its liver-friendly nutrients.

Use Fresh Garlic
For maximum antioxidants and other beneficial compounds, chop, crush or mince it right before adding it to your food (or don’t cook it at all). Studies suggest that cooking causes many of its beneficial nutrients to be lost.

Pair It with a Healthy Lifestyle
Exercising, following a liver-friendly diet, and regular checkups are the bases of reversing fatty liver. Garlic can be a nice addition, but it’s not the cure for NAFLD.

Listen to Your Body
If you feel any discomfort or suspect garlic triggers unwanted symptoms, you better stop having it and talk to a healthcare professional. With all foods, it’s best to keep track of what you eat and how you feel afterward.

Bottom line

After learning more about garlic, I felt it was safe to enjoy it again in small amounts, so I started adding it here and there – even before getting the confirmation that I had reversed my fatty liver.

Could that have happened without garlic? Absolutely. Garlic alone didn’t magically heal my liver. But at least it didn’t cause any setbacks – and I’ll take that as a win. After all, it’s smelly, but it tastes great!

As long as you stick to reasonable amounts, it’s unlikely to harm your liver. Especially if you do everything right and switch to a healthier lifestyle overall.

If your body reacts fine to it, there’s no need to toss it aside – unless if told by a professional. Then again, if you find yourself feeling worse after a garlicky meal, it may be worth cutting back and exploring other options.

In other words, there’s no silver bullet. Garlic might add flavor – and potential minor benefits – to your meal plan, but regular exercise, a solid, liver-friendly diet, and consistent medical monitoring make the real difference.

You can now continue learning about various other foods and fatty liver, such as almonds and almond milk or barley.

Now back to you – what do you think about garlic? Is it something that you keep eating for the claimed benefits, or you’ve removed it from your diet entirely just to be safe?
