Why Your Liver Deserves Support
Your liver performs over 500 vital functions. When it’s stressed, you can feel it throughout your body in the form of fatigue, sluggish digestion, and skin issues. Proactively supporting your liver can help:
- Protect Liver Cells: Shielding them from damage caused by toxins and free radicals.
- Enhance Detoxification: Aiding the two-phase process your liver uses to neutralize harmful substances.
- Promote Healthy Bile Flow: Crucial for digesting fats and clearing out waste. The function of your liver is closely tied to your entire digestive system, including the need for proper digestive enzymes.
The 5 Best Liver Support Supplements on iHerb
Here are the top-rated, science-backed liver health supplements available on iHerb.
1. Milk Thistle Extract: The Guardian of Liver Cells 🛡️
Why it’s essential: Milk Thistle is the most researched and well-known herb for liver health. Its active compound, silymarin, is a powerful antioxidant that helps protect liver cells from damage and supports their regeneration. It’s the first line of defense for a stressed liver.
The iHerb Advantage: California Gold Nutrition’s Silymarin Complex is a top-tier choice. It contains a standardized extract of Milk Thistle plus a synergistic blend of other liver-supporting herbs like Dandelion, Artichoke, and Turmeric for comprehensive support.
Best for: General liver protection, daily support, and antioxidant defense.
Milk thistle is best known for its liver-protective effects, thanks to its active compound silymarin, which acts as a powerful antioxidant. Some studies suggest milk thistle extract may help improve liver function and promote liver cell repair, especially in conditions like fatty liver disease and cirrhosis. While results are mixed and more research is needed, it remains a popular natural option for supporting liver health (Cleveland Clinic, Healthline).

2. NAC (N-Acetyl Cysteine): The Master Antioxidant Precursor ✨
Why it’s essential: NAC is a supplement form of the amino acid cysteine. Its primary role in the liver is to serve as a direct precursor to glutathione, your body’s most powerful antioxidant. Supporting glutathione production is critical for Phase II detoxification, where toxins are neutralized and prepared for elimination. It’s a more powerful antioxidant than even Turmeric Curcumin.
The iHerb Advantage: NOW Foods NAC provides a potent 600 mg dose in a simple, effective capsule. It’s a trusted and affordable way to directly boost your body’s master antioxidant system and support respiratory health.
Best for: Enhancing detoxification, boosting antioxidant levels, and protecting against oxidative stress.
NAC (N-acetyl cysteine) is a powerful antioxidant precursor that helps the body replenish glutathione, its main cellular defense against oxidative stress (NCBI). Research shows NAC supports detoxification, reduces inflammation, and protects cells from damage (ACS Publications). Its benefits extend to liver health, respiratory support, and overall cellular resilience (StatPearls).

3. TUDCA: The Advanced Bile Flow Optimizer 🌊
Why it’s essential: TUDCA (Tauroursodeoxycholic Acid) is a water-soluble bile acid that has gained massive popularity for advanced liver support. It works by improving the flow and quality of bile, which acts like a “river” to carry toxins out of the liver. It also helps reduce cellular stress within the liver itself.
The iHerb Advantage: Nutricost TUDCA offers a high-quality, 250 mg dose per capsule. This is a more advanced supplement, ideal for those looking to provide serious support for liver function and bile duct health.
Best for: Advanced liver support, promoting healthy bile flow, and reducing liver cell stress.
TUDCA (tauroursodeoxycholic acid) is a bile acid shown to support healthy bile flow and protect liver cells from stress and toxins. Research suggests TUDCA supplementation may benefit liver health, aid in detoxification, and even support digestive and metabolic function. Its growing popularity is backed by promising studies, though more human research is still needed.

4. Artichoke Extract: The Digestive & Cholesterol Aid Artichoke
Why it’s essential: Artichoke extract is another bile-booster (a choleretic). Increasing bile production not only supports the liver’s cleansing process but also aids in the digestion of fats and helps maintain healthy cholesterol levels already within the normal range.
The iHerb Advantage: NOW Foods Artichoke Extract provides a standardized 450 mg dose. It’s an excellent choice for those who want to support their liver and improve digestive comfort simultaneously.
Best for: Supporting both liver health and fat digestion, and maintaining healthy cholesterol.
Artichoke extract is clinically shown to support liver health, aid digestion, and help lower cholesterol. Studies indicate artichoke leaf extract protects liver cells from damage, improves cholesterol processing, and may ease symptoms of indigestion and IBS (Healthline). Its antioxidant and anti-inflammatory properties make it a popular natural choice for metabolic and digestive wellness.
➡️ Check Price on iHerb: NOW Foods, Artichoke Extract, 450 mg, 90 Veg Capsules
5. Dandelion Root: The Gentle Detoxifier 🌱
Why it’s essential: Dandelion root has been used for centuries in traditional medicine as a gentle liver tonic. It is believed to support the liver’s natural detoxification processes and has mild diuretic properties, helping the body flush out toxins.
The iHerb Advantage: Nature’s Way Dandelion Root is a pure, simple, and trusted herbal supplement. It’s a great option for those looking for gentle, daily support or as part of a wider natural wellness routine.
Best for: Gentle daily detoxification and traditional liver support.
Dandelion root is a gentle detoxifier traditionally used to support liver, kidney, and digestive health. Research shows dandelion root extract helps protect the liver from oxidative stress and may aid digestion and regularity thanks to its prebiotic fiber inulin. Its antioxidant and mild diuretic properties make it a popular choice for natural cleansing and gentle detox support.
