Milk thistle extract is the cornerstone of this product, standardized to deliver 300 mg of silymarin per serving—a dose supported by clinical evidence for liver protection and metabolic health. Silymarin, particularly its active constituent silybin, has been studied for decades for its ability to reduce oxidative stress, improve liver enzyme levels, and support regeneration of hepatocytes in conditions like nonalcoholic fatty liver disease (NAFLD) and drug-induced liver injury [1][2]. At higher therapeutic doses (420–700 mg three times daily), silymarin has shown histological improvement in nonalcoholic steatohepatitis (NASH), though this product provides a more moderate amount suitable for maintenance rather than intensive intervention.
The inclusion of dandelion, artichoke, curcumin, ginger, and BioPerine® adds multi-pathway support for liver detoxification, lipid metabolism, and systemic inflammation. While these supporting ingredients are included at lower doses, their synergistic potential enhances the product’s overall functional profile. Notably, the presence of BioPerine® (black pepper extract) significantly improves the bioavailability of curcumin and possibly other polyphenols, addressing a key limitation in herbal formulation efficacy. This makes the product a comprehensive, evidence-informed choice for individuals seeking integrative liver and metabolic support.
Quick Summary
Full ingredient transparency with exact amounts listed for all components. No proprietary blends, allowing for accurate dose assessment and clinical evaluation.
The primary ingredient, milk thistle, is dosed within the clinical range for liver support (300 mg/day), warranting a strong efficacy score. Supporting ingredients are below clinical levels but contribute synergistically, especially with BioPerine® enhancing curcumin absorption. Overall, this is a well-formulated supplement for general liver and metabolic health.
The inclusion of BioPerine® significantly enhances the bioavailability of curcumin and potentially other polyphenols. While milk thistle is not in a phytosome form (which offers superior absorption), the formulation still achieves good functional bioavailability through piperine synergy.
Generally safe for most adults, but notable herb-drug interaction risks exist due to piperine and milk thistle affecting CYP450 enzymes. Contraindicated in bile duct obstruction. Quality brand with likely good manufacturing practices.
Suggested: 2 servings/day to reach clinical midpoint
Why Take This Product
Key Benefits
- Liver Protection and Support: Milk thistle extract (silymarin) has demonstrated hepatoprotective effects in clinical trials, reducing liver enzymes (ALT, AST) and improving histological markers in nonalcoholic steatohepatitis (NASH) at doses of 420–700 mg three times daily [2]. While this product provides a lower dose (300 mg), it falls within the range (140–420 mg/day) commonly used for general liver support and detoxification.
- Antioxidant and Anti-inflammatory Effects: Silymarin, curcumin, and ginger all contribute potent antioxidant activity by reducing oxidative stress markers and suppressing pro-inflammatory cytokines such as TNF-α and IL-1β [1][8][20]. This combination may help mitigate chronic inflammation associated with metabolic syndrome and liver disease.
- Improved Lipid and Glucose Metabolism: Dandelion and artichoke extracts have shown lipid-lowering effects in preclinical and clinical studies, reducing total cholesterol, LDL, and triglycerides [12][5]. Ginger has been shown to improve fasting glucose, HbA1c, and insulin sensitivity in type 2 diabetes at 3 g/day [7], suggesting metabolic benefits even at lower doses.
- Enhanced Bioavailability via BioPerine®: The inclusion of 5 mg of black pepper extract (piperine) significantly increases the absorption of curcumin—by up to 2000%—and may enhance the uptake of other polyphenols in the formula, improving overall efficacy [11].
Who Should Take This
Potential Side Effects
Ingredient Breakdown
Each ingredient in this formula plays a defined role: milk thistle is the primary hepatoprotective agent; dandelion and artichoke support bile flow and liver detoxification; curcumin and ginger provide systemic anti-inflammatory and antioxidant effects; and BioPerine® enhances the bioavailability of key compounds. The doses reflect a balance between clinical evidence and practical formulation limits.
Primary Ingredients
Milk Thistle Extract
Hepatoprotection, antioxidant, anti-inflammatory
Dose falls within the clinical range for liver support (140–420 mg/day). While not a phytosome formulation (which offers superior bioavailability), it is suitable for general use. Standardization ensures consistent silymarin content.
Standardized silymarin extract from milk thistle seeds, providing antioxidant and liver-regenerating effects. Shown to improve liver enzymes and histology in nonalcoholic steatohepatitis (NASH) at higher doses [2].
Supporting Ingredients
There are 5 supporting ingredients.
Practical Recommendations
- Take With Meals For Optimal Absorption: Consume one capsule with food to enhance the absorption of fat-soluble compounds like curcumin and silymarin, and to minimize potential gastrointestinal discomfort from ginger or artichoke.
- Consider Doubling The Dose For Therapeutic Use: For individuals with diagnosed NAFLD or elevated liver enzymes, taking two capsules daily may bring the silymarin dose closer to the upper end of the clinical range (600 mg/day), potentially improving outcomes.
- Monitor Medication Interactions: If you are taking prescription drugs—especially statins, anticoagulants, antidiabetics, or anticonvulsants—consult your healthcare provider before use due to potential interactions with milk thistle and piperine.
- Use Consistently For At Least 8–12 Weeks: Liver enzyme improvements and metabolic benefits typically require sustained use. Clinical trials on silymarin and artichoke show measurable effects after 8–12 weeks of daily supplementation.
Is it Safe?
While generally safe for most adults, this product contains several ingredients with documented herb-drug interaction potential. Piperine can increase the absorption of pharmaceuticals, raising the risk of toxicity. Milk thistle may weakly interact with hormone-sensitive conditions and certain medications metabolized by CYP3A4 and CYP2C9. Quality control and standardization of extracts are critical, and California Gold Nutrition is known for transparent labeling and third-party testing.
Safety & Considerations
- Herb-Drug Interaction: Piperine (BioPerine®) inhibits CYP3A4 and P-glycoprotein, potentially increasing blood levels of medications such as statins, anticoagulants, and anticonvulsants.
- Hepatic Condition: Avoid in bile duct obstruction due to choleretic effects of dandelion and artichoke.
- Allergy: Potential allergic reaction in individuals sensitive to Asteraceae plants (e.g., ragweed, daisies).

The Science
The efficacy of this product hinges on the dose and form of milk thistle extract, which is the primary active ingredient. At 300 mg per serving, it falls within the clinical range for liver support (140–420 mg/day), though below the higher doses used in NASH trials. Supporting ingredients are included at sub-clinical levels but contribute synergistically. The use of BioPerine® significantly boosts curcumin absorption, improving the functional impact of lower doses.
