5

Choline

Choline is an essential nutrient (recognized by IOM in 1998) critical for brain development, liver function, and methylation. It is the precursor to acetylcholine (the learning neurotransmitter) and phosphatidylcholine (cell membranes). Over 90% of Americans are deficient. Key forms include Alpha-GPC, CDP-Choline, and choline bitartrate.

Spice containing curcumin as active compound. Powerful anti-inflammatory and antioxidant.

Benefits: Powerful anti-inflammatory effects, Strong antioxidant properties, May support joint health, May support brain health, May support liver function

Found in 5 products

7

Methionine

L-Methionine is an essential sulfur-containing amino acid and the initiator of all protein synthesis (start codon). It is the precursor to SAM-e (S-adenosylmethionine), the universal methyl donor, and cysteine/glutathione via the transsulfuration pathway. Critical for methylation, detoxification, and antioxidant defense.

Benefits: [object Object], [object Object], [object Object], [object Object], [object Object]

L-Glutathione

Glutathione (GSH) is the body's master antioxidant, a tripeptide of cysteine, glutamic acid, and glycine. It is central to detoxification (Phase II conjugation), immune function, and cellular protection. Liposomal and reduced (GSH) forms have improved bioavailability over standard oral glutathione.

Benefits: [object Object], [object Object], [object Object], [object Object], [object Object], [object Object]

Milk Thistle

Milk thistle (Silybum marianum) contains silymarin, a complex of flavonolignans (silybin, silychristin, silydianin) with the most robust evidence of any herb for liver protection. Silybin is the most active component, protecting hepatocytes from toxins, stimulating liver regeneration, and acting as a potent antioxidant.

Broccoli Seed Extract

Broccoli seed extract is the richest source of sulforaphane (via glucoraphanin/myrosinase), one of the most potent activators of the Nrf2 antioxidant pathway. Nrf2 activation upregulates over 200 cytoprotective genes. Research supports cancer prevention, detoxification, and neuroprotective effects.

Benefits: [object Object], [object Object], [object Object], [object Object]

TUDCA

Tauroursodeoxycholic acid (TUDCA) is a water-soluble bile acid found naturally in small quantities in human bile. It is a potent chemical chaperone that reduces endoplasmic reticulum (ER) stress and protects cells from apoptosis. Used clinically for cholestatic liver diseases and emerging as a powerful cytoprotective agent.

Benefits: [object Object], [object Object], [object Object], [object Object], [object Object]

N-Acetyl Cysteine (NAC)

N-Acetyl Cysteine (NAC) is the acetylated form of L-cysteine with superior bioavailability. It is the most effective oral precursor to glutathione and has been used clinically for 50+ years. FDA-approved as acetaminophen antidote; extensively researched for respiratory, mental health, liver, and immune applications.

Stacking Tips

The liver support stack is NAC (600mg 2x/day) + Milk Thistle (400mg) + TUDCA (250mg). NAC boosts glutathione production, Milk Thistle protects liver cells, and TUDCA supports bile flow — covering all major liver health pathways.

For enhanced detoxification: Add Curcumin (500mg) for anti-inflammatory support and Selenium (200mcg) which is required for glutathione peroxidase activity.

Important: NAC is best taken on an empty stomach. Milk Thistle and TUDCA with meals. If taking liposomal glutathione instead of NAC, take on an empty stomach for best absorption.

Frequently Asked Questions

What is the best supplement for liver health?

NAC (N-Acetyl Cysteine) at 600-1200mg daily is the most evidence-backed liver supplement. It directly boosts glutathione — the livers primary detoxification molecule. Milk Thistle (silymarin) is the most traditionally used and well-studied hepatoprotective herb.

Is NAC or glutathione better for the liver?

NAC is generally preferred because it is well-absorbed orally and the body converts it to glutathione as needed. Regular glutathione is largely destroyed in digestion. If you want direct glutathione supplementation, use liposomal or acetyl-glutathione forms. NAC is more cost-effective.

Does Milk Thistle actually protect the liver?

Yes. Silymarin (the active compound in Milk Thistle) has extensive clinical evidence for liver protection. It stabilizes liver cell membranes, promotes liver cell regeneration, acts as an antioxidant, and has anti-inflammatory properties. It is used clinically in Europe for liver disease.

What is TUDCA and should I take it?

TUDCA is a bile acid that supports liver and gallbladder health. It protects against bile acid toxicity and supports liver cell health. It is particularly popular among athletes using liver-stressing compounds. For general liver support, 250mg daily is the typical dose.

Can supplements reverse fatty liver?

Some supplements may help. Berberine has clinical evidence for reducing liver fat. NAC and Milk Thistle support liver function and reduce inflammation. Omega-3 fatty acids help reduce liver triglycerides. However, lifestyle changes (diet, exercise, weight loss) remain the primary treatment for fatty liver.
