Supplements for Fatty Liver: 7 Options, Who They Fit, and What to Know First
By Easton Bryant, PharmD, Founder, North Century Pharmacy
If you've been told you have fatty liver, you've probably also been told to "eat better and lose weight," and then sent home. At surface level, that advice is right, but it leaves out a lot.
Here's where I come from when someone asks me about supplements for fatty liver support. None of them is approved to treat fatty liver, and none replaces the basics: cutting back on sugar and refined starch, moving, sleeping, and losing weight if you carry extra. But some have real research behind them, and which ones make sense depends on the person. So instead of one big list for everybody, I'll tell you who each one is for and why I'd reach for it.

1. Omega-3s
At a glance: for high triglycerides and achy joints
When I see triglycerides creeping up on someone's labs, especially alongside fatty liver, omega-3s are usually one of my first adds. I think of them as a two-for-one. If you're dealing with stiff, achy joints too, that's another reason I like them.
Here's the research. A review of 22 trials (1,366 people) found omega-3s improved liver fat more often than placebo, mostly on ultrasound, and clearly lowered triglycerides. Liver enzymes didn't change much. Most of the trials were small and short, so I'd call this promising, not proven.
This might be you if: your triglycerides are above where you'd like them (I aim for under 80), or your joints ache and you're not sure why.
Our pick: OptiOmega
Know first: If you take a blood thinner, talk to your provider.
2. Berberine
At a glance: for insulin resistance and belly weight
Berberine is the one I think about when the problem looks like blood sugar and insulin. If you carry weight around the middle, crash or crave sweets after meals, or your triglyceride-to-HDL ratio is over 3, berberine is worth a conversation. That ratio is one of the early hints that insulin resistance is in the picture.
The research is encouraging. A 2024 review of 10 trials (811 people) linked berberine to lower ALT, AST, triglycerides, and insulin resistance. Side effects were mild, mostly stomach upset. If you want the full story, we wrote about Berberine vs. Metformin.
This might be you if: you're past menopause and the weight shifted to your belly, your fasting insulin is high, or you ride the blood sugar roller coaster.
Our pick: BERBERINE 5X
Know first: Berberine can lower blood sugar. If you take diabetes medicine or any prescription, talk to your provider before adding it. I usually add it after the basics are in place, not first.
3. Phosphatidylcholine
At a glance: for anyone whose liver needs more choline, including women past menopause, people without a gallbladder, and people with a gene variant that makes it harder to produce
Your liver needs choline to package fat and move it out. Phosphatidylcholine is a form of choline, and it also supports bile flow, which matters a lot if your gallbladder is gone.
Most people don't realize that your body doesn't only get choline from food. Your liver also makes its own, using an enzyme called PEMT. In fact, PEMT is the only source of choline the liver makes. In one study, people with more advanced fatty liver had lower PEMT activity in their livers, and that included postmenopausal women. When PEMT runs low, you depend more on what you eat. That's a big reason choline matters for some people more than others.
Two things can change how well that system works. One is your hormones. Research on women's choline needs shows that estrogen and genetic variation both play a role, which helps explain why needs can change after menopause. The other is your genes. Some people carry variants in the PEMT gene, and that's something we test for on the UNLOCK functional genetic test, which you can get through our app. If you'd rather know than guess, that's how.
On the diet side, in one study of people with fatty liver, postmenopausal women who ate less than half the recommended choline had more liver scarring (about half, versus 30% for women with enough). That study shows a link, not cause and effect, so I don't oversell it. But it fits what I see in consults.
This might be you if:
-
You have fatty liver and rarely eat eggs, liver, or other choline-rich foods
-
You're past menopause and the weight has shifted to your belly
-
You had your gallbladder removed
-
You've done genetic testing and have a PEMT variant, or you'd like to find out
-
Your liver enzymes or scan results suggest your liver is working harder than it should
Our pick: Phosphatidylcholine
4. Liposomal Glutathione
At a glance: for liver enzymes that run higher than you'd like, and extra antioxidant support
I don't talk about this one as much as I should. Glutathione is the main antioxidant your body makes, and your liver is where a lot of that work happens. Think of it as your liver's own cleanup crew, which handles the wear and tear that comes from processing everything you eat, drink, and take.
Here's what the research looks like. In a 4-month pilot study of 29 people with fatty liver, taking 300 mg of oral glutathione daily was linked to a drop in ALT, by a median of about 13%. ALT is the liver enzyme I told you to watch in my fatty liver symptoms article. This study was small, had no comparison group, and a few people stopped because of fatigue, higher blood pressure, or a rash, so I'd call it promising but early.
That's why I like the liposomal form. It's designed to help your body absorb glutathione better than a standard capsule. It's one of the products I think should be more popular, and I'll admit I haven't talked about it enough.
This might be you if:
-
Your ALT runs above where you'd like it (I look closer at anything over about 30)
-
You've already built the foundations and want one more liver-focused tool
-
You take several medications or supplements and want to support your liver's own defenses
Our pick: Liposomal Glutathione
Know first: If you take any medication, check with your provider before adding it. The research is early, so I treat this as a support, not a fix.
5. Fiber
At a glance: for cravings, constipation, and blood sugar swings
Fiber isn't flashy, but I put it in almost everyone's plan. It slows how fast sugar hits your blood and helps you feel full, which supports the very foundations that matter most for fatty liver.
This might be you if: you're hungry again an hour after eating, you crave sweets in the afternoon, or things move slowly.
Our pick: Fiber Lean
Know first: Start low, go slow, and drink water, or you'll get bloated.
6. Vitamin D3 + K2
At a glance: for low vitamin D and anyone without a gallbladder
This one comes straight from the woman in the story in my fatty liver symptoms article. Her labs were fine except for vitamin D. Vitamin D needs bile to be absorbed, so without a gallbladder, levels often run low. Low vitamin D also shows up often in people with fatty liver. The research is mixed on whether fixing it changes the liver, but I never want to leave a deficiency alone.
That's why I like a micellized form, which is built to absorb without much bile, paired with K2.
This might be you if: your vitamin D came back low, you had your gallbladder removed, or you feel run down and achy and haven't checked.
Our pick: Micellized D3/K2
Know first: Test your level so you're not guessing. And don't take D without knowing where you start.
7. Digestive Enzymes with HCl
At a glance: for trouble with heavy meals, bloating, and anyone without a gallbladder
This one is about digestion, not the liver directly, and I want to be upfront about that. But a lot of people with fatty liver and no gallbladder struggle here, and when digestion works better, everything else I'm asking of you gets easier. It pairs well with #3 and #6.
Stomach acid is the first step in breaking down your food, and it also helps you absorb nutrients like B12 and magnesium. If you remember the heartburn medicine part of my symptoms article, you know why that matters. This formula combines digestive enzymes with HCl to support that first step.
This might be you if: you've had your gallbladder out and notice loose stools, urgency, or bloating after fatty meals. More on that in Gallbladder Symptoms: What's Normal and What's Not.
Our pick: Digestive Enzymes HCl
Know first: If you have ulcers or gastritis, or you take NSAIDs or an acid-reducing medicine, check with your provider before adding HCl.
Others you'll see online
-
Vitamin E: Liver guidelines list it as an option for non-diabetic adults with biopsy-proven NASH, using high doses studied under a provider's care. Some reviews have raised long-term safety questions. This is a conversation with your provider, not a DIY add.
-
Milk thistle: A review of 26 trials found lower liver enzymes, but the studies varied a lot and were low quality. Promising, not proven.
-
NAC: Mostly lab and animal research so far. Human evidence is limited.
How I'd Put It Together
Please don't start all seven tomorrow. I know it's tempting. But when you add everything at once, you can't tell what's helping, and if something doesn't agree with you, you won't know which one it was. Here's the order I'd go in, and why.
1. Start with the foundations and the 7-DAY RESET.
This comes first because everything else works better on top of it. Cutting back on added sugar and refined starch, walking after meals, and sleeping well are what take pressure off your liver in the first place. The Reset gives you a simple week to get those habits going, and it supports healthy weight goals and liver health. It also shows you where you're starting from, which tells you how much else you need.
2. Add the basics that fit you: omega-3s, fiber, and D3/K2.
These come next because they're the most broadly useful. They fill gaps that a lot of people have, and they're the easiest to fit around other medications and health conditions. Pick the ones that match your story. Omega-3s if your triglycerides run high, fiber if your digestion or blood sugar needs help, D3/K2 if your vitamin D is low or you have trouble absorbing fat.
3. Add berberine, phosphatidylcholine, or glutathione if your story points there.
These come later because they fit specific situations rather than everyone, and the research on glutathione is still early. Berberine tends to make sense when insulin and blood sugar are part of the picture. Phosphatidylcholine tends to make sense when choline or bile flow is part of it, as with no gallbladder. Glutathione tends to make sense once the foundations are in place and your liver enzymes still run high. Berberine can also affect blood sugar, so if you take diabetes medication, check with your provider before you add it. That's why I want you settled on steps 1 and 2 first.
4. Recheck your labs at 90 days and adjust.
It takes time for your body to respond, so this is when I look at the numbers. Recheck what you started with, like triglycerides, fasting insulin, and fasting glucose. If they're moving the right way, stay the course. If they aren't, that's when we change the plan, not before.
One thing rarely fixes a problem with many causes. That's why I'd rather build a plan around you than hand you a shopping list.
Not medical advice. Talk with your provider before adding supplements, especially if you take medication. Never stop or change a prescription on your own.
Where to Start
If you want to follow my advice and start with the 7-DAY RESET, here's what I'd do: join NCPlus and download the app first. NCPlus is our membership with a community, ongoing education, and member pricing. When you join, you get an automatic 10% off the 7-DAY RESET, and the same 10% off the REFOCUS30 labs and masterclass. If you're planning to do any of those, your monthly membership will save you a ton of money right away.
If you'd rather see your numbers first, REFOCUS30 gives you functional labs and a plan built around them, plus a masterclass that walks you through what your results mean. As a member, you'd save on that, too.
Either way, you won't be figuring this out alone. The app puts you in a community where you can ask questions, and you'll get ongoing education with pharmacist and dietitian guidance.
