Insider Health Report

Top 7 liver supplements, tested and ranked. I spent around $500 across five months. Here’s what actually moved my bloodwork.

My own ALT came back at 62 U/L, and the scan showed fatty liver. After twelve years reporting on consumer health, all my doctor offered me was the same script I had heard for years: lose weight, cut alcohol, recheck in a year. I followed it. What nobody answered was the obvious question: if those changes slow new fat from reaching my liver, what replaces the glutathione already used up, repairs the damage already done, and clears the fat still trapped there?

Short on time? Out of the seven I tested, only one dropped my ALT from 56 to 31 U/L in eight weeks.

See the winner

So I stopped assuming and started testing. Over five months I bought seven liver products—multi-herb blends, drainage drops, direct glutathione, dry NAC capsules, and complete formulas—and ran each for four weeks with fresh bloodwork between cycles. Total tab, including products and testing: around $500.

Milk Thistle Liver Support Blend

Milk Thistle Liver Support Blend

Wrong target

Bloodwork: ALT 63 U/L — no improvement

VERDICT

The most recommended liver ingredient on the planet—and still the wrong place to start. It protects around the problem without replacing depleted glutathione or clearing the fat causing the damage.

DOSE300mg milk thistle + multi-herb stackper public label and project information
FORMATCapsules, usually two daily
PRICETypically $20–$40 per bottle

What works

  • Familiar ingredient with broad consumer recognition
  • Usually easy to take and widely available
  • Multi-herb labels look comprehensive at first glance

What doesn't

  • Does not supply NAC to rebuild glutathione
  • Does not include NAD+ for the trapped-fat backlog
  • Adds more herbs without completing the two jobs

Milk thistle was where I started because it was the answer every search result seemed to repeat. I took it for four weeks exactly as directed. ALT after: 63 U/L—one point higher than the 62 that started this investigation. Protection language was not the same as a mechanism that repaired the damage and cleared the fat already there.

Lymphatic Drainage Drops

Lymphatic Drainage Drops

Mechanism mismatch

Bloodwork: ALT 64 U/L — no improvement

VERDICT

A mechanism that sounds scientific and isn’t. “Drainage” has nothing to do with why trapped fat is damaging liver cells or why ALT and AST remain elevated.

DOSEOne dropper per dayper public label and project information
FORMATLiquid tincture
PRICETypically $32–$45 per bottle

What works

  • Simple one-dropper ritual
  • Easy to swallow
  • Feels more active than taking another capsule

What doesn't

  • Targets a drainage story instead of glutathione depletion
  • Provides neither full-dose NAC nor NAD+
  • Cannot explain how trapped liver fat is processed

I bought the drops because my feed kept showing me the same clogged-drain metaphor. After four weeks, my ALT was 64 U/L. The metaphor was memorable. The number told me the mechanism was wrong. A formula can feel like action and still miss the actual job the liver needs completed.

Ritual Labs Happy Liver

Ritual Labs Happy Liver

Polished, underpowered

Bloodwork: ALT 60 → 57 U/L

VERDICT

Real NAC finally appears on the label—but at an incomplete serving, inside a dry capsule, and without NAD+ for the fat-processing job.

DOSE500mg NAC + milk thistle + cholineper public label and project information
FORMATVegetarian capsules, two daily
PRICETypically $40–$50 per bottle

What works

  • Includes real NAC rather than a token label sprinkle
  • Disclosed formula and clean presentation
  • Adds choline alongside familiar liver ingredients

What doesn't

  • NAC serving stops below the full 1,200mg target
  • Dry capsules keep the sulphur-burp objection alive
  • No NAD+ to complete the trapped-fat job

This was the first formula that made me stop and look twice because NAC was finally on the label. My ALT moved from 60 to 57 U/L after four weeks—but three points was not the result I was spending premium money to get. Partial NAC was still partial logic, and the missing NAD+ became impossible to ignore.

LiverMD by 1MD Nutrition

LiverMD by 1MD Nutrition

Long label, diluted logic

Bloodwork: ALT 62 U/L — back where I started

VERDICT

The most advertised liver supplement is a multivitamin in liver branding. A long label cannot compensate for an underpowered NAC center and no NAD+ answer.

DOSEMulti-ingredient liver blendper public label and project information
FORMATTwo capsules daily
PRICE$52 retail / about $42 subscription

What works

  • Broad familiar ingredient profile
  • Established manufacturing and testing language
  • Clean daily capsule format

What doesn't

  • NAC is not the decisive center of the formula
  • No clear NAD+ fat-processing step
  • The longest label still leaves the same two-job gap

After four weeks, my ALT was 62 U/L—right back where this investigation started. That was the point where I stopped counting ingredients. A long label can look impressively complete while completely missing the dose and mechanism that move the number.

NOW Foods Glutathione 250mg

NOW Foods Glutathione 250mg

Right substance, wrong strategy

Bloodwork: ALT 61 U/L — no meaningful change

VERDICT

The right protective substance, given the wrong way. The liver needs NAC’s cysteine to rebuild glutathione inside cells—and it still needs NAD+ to clear the trapped fat.

DOSE250mg glutathione per capsuleper public label and project information
FORMATVegetarian capsule
PRICETypically $15–$22 per bottle

What works

  • Targets the protective substance the liver relies on
  • No sulphur taste
  • Affordable and easy to find

What doesn't

  • Does not use full-dose NAC to rebuild glutathione
  • Does not add NAD+ for trapped-fat processing
  • Solves neither the dose nor the two-job problem

After four weeks, my ALT was 61 U/L. That one-point change taught me the difference between swallowing the finished substance and supplying the raw material the body uses to rebuild it. It moved me closer to NAC—but still left the trapped-fat question untouched.

#2RUNNER-UP
Investigated May 2026 · 28 days
Thorne NAC 500mg

Thorne NAC 500mg

Credible NAC, half the job

Bloodwork: ALT 56 U/L — best failed result

VERDICT

The right precursor, but still only half the formula. NAC rebuilds glutathione and handles the damage. It does not explain how the liver clears the fat causing that damage.

DOSE500mg NAC per capsuleper public label and project information
FORMATDry-powder capsule
PRICETypically $25–$35 per bottle

What works

  • Uses the correct glutathione-building precursor
  • Simple formula from a respected brand
  • Clear ingredient labeling

What doesn't

  • Requires extra capsules to reach a 1,200mg serving
  • Dry powder can bring sulphur burps and stomach discomfort
  • No NAD+ to clear the trapped-fat backlog

This was the first product that moved my ALT enough to hold my attention: 56 U/L after four weeks. It confirmed the first half of my investigation—NAC made the glutathione story make sense. It also exposed the final gap. Protecting the liver was not the same as helping it process the fat causing that damage.

Fascigen NAC1200 + NAD+ pouch

Fascigen NAC1200 + NAD+

The complete two-job formula

Bloodwork: ALT 56 → 31 U/L in eight weeks

VERDICT

The only formula that completes both jobs. NAC1200 rebuilds the glutathione the liver uses to protect and repair itself. NAD+ helps transform the trapped fat into energy. MCT oil carries both in an easy-to-take softgel, boosts absorption by up to 80%, and removes the sulphur taste ordinary NAC capsules have.

Why it ranked #1

  • Full 1,200mg NAC serving to rebuild glutathione
  • NAD+ for the trapped-fat backlog
  • MCT oil boosts absorption by up to 80%
  • No disgusting sulphur taste or dry-powder ritual
  • Third-party tested patented formula

This is where my investigation ended. After eight weeks with Fascigen NAC1200 + NAD+, my ALT dropped from 56 to 31 U/L. My AST came down with it, the fat trapped in my liver was finally moving in the right direction, and the afternoon crash and fog that had become normal started lifting. It was the first time since my diagnosis that I felt in control of my health again.

WHAT THIS INVESTIGATION CHANGED

Four rules I would use before buying another liver supplement

  1. 1

    Ask what will move the numbers. “Liver support” means nothing if the formula cannot explain how liver fat, ALT, and AST come down.

  2. 2

    Ignore the marketing words. “Cleanse,” “reset,” and “restore” are empty unless the formula rebuilds glutathione and clears trapped fat.

  3. 3

    Read the dose, not the front label. If NAC is buried in a blend or requires a pile of capsules, you are not buying the full mechanism.

  4. 4

    Do not stop at NAC. NAC handles the damage. NAD+ clears the fat backlog. You need both jobs completed.
