Overview

Uvora Milk thistle: Time-Release Liver Protection

Uvora Milk thistle Time Release is specially formulated to slowly and consistently deliver Silymarin β€” the active flavonolignan complex from Milk thistle β€” to your hardworking liver. Your liver performs over 500 functions, and one of the most critical is ridding your body of toxins. Silymarin may help protect the liver from those very toxins as it works to flush them out, supporting the organ's ability to function at full capacity.

What sets this formula apart is its time-release delivery. Each 350 mg tablet of Milk thistle herb extract is standardized to 80 percent Silymarin (280 mg), ensuring a steady supply of this protective compound throughout the day rather than a single spike. This approach aligns with what researchers know about Silymarin's relatively short half-life and rapid metabolism.

Beyond liver protection, the Silymarin found in Milk thistle may block some toxins from ever entering the body's systems, helping to prevent subsequent tissue damage. It is also a rich source of antioxidants and encourages protein synthesis in the cells of the liver β€” a key mechanism behind its hepatoprotective reputation.

How It Works

The Science Behind Silymarin and Liver Defense

Milk thistle (Silybum marianum) has been valued for liver support for over 2,000 years, with therapeutic use first documented by the Greek physician Dioscorides. Modern research has identified the mechanisms behind this ancient reputation. Silymarin exhibits hepatoprotective properties through several pathways: acting as an antioxidant, an anti-inflammatory, and an antifibrotic substance.

As an antioxidant, Silymarin directly scavenges free radicals produced during the metabolism of toxic substances such as ethanol, acetaminophen, and carbon tetrachloride. It inhibits lipid peroxidation, enhances hepatic glutathione levels, and upregulates endogenous antioxidant enzymes via activation of the Nrf2 pathway. Clinical studies in chronic liver disease populations confirm enhancement of measurable antioxidant defense markers.

On the anti-inflammatory front, Silymarin regulates cytokines responsible for inducing inflammation. It has been shown to down-regulate COX-2, a key mediator of inflammatory pathways, and it inhibits the NF-ΞΊB transduction cascade β€” a central controller of inflammatory gene expression.

Silymarin also stabilizes biological membranes and increases protein synthesis within hepatocytes. By altering the structure of the hepatocyte external membrane, it may prevent the entrance of xenobiotics (foreign substances) into liver cells β€” this is the mechanism behind its traditional use in cases of mushroom poisoning.

What's inside

Key Ingredients

Milk thistle seed extract β€” 350 mg
Standardized to 80% Silymarin, Milk thistle seed extract (<em>Silybum marianum</em>) is one of the most extensively studied botanicals for liver health. The active complex, Silymarin, is a mixture of flavonolignans including silybin A and B (the most pharmacologically active constituents), isosilybins A and B, silychristin, silydianin, and the flavonoid taxifolin. Research suggests Silymarin supports multiple body systems. For <strong>liver health</strong>, multiple RCTs and systematic reviews β€” including a 2023 review of 29 RCTs encompassing 3,846 participants β€” show meaningful reductions in liver enzymes (ALT, AST), particularly in non-alcoholic fatty liver disease. A pooled analysis of trials in cirrhosis patients found Silymarin associated with a significant reduction in liver-related deaths, though results across other liver disease types are mixed. For <strong>environmental toxin protection</strong>, Silymarin protects hepatocytes from damage caused by heavy metals, alcohol, acetaminophen, carbon tetrachloride, and pesticides by scavenging free radicals, enhancing glutathione levels, inhibiting lipid peroxidation, and modulating detoxification enzymes. For <strong>antioxidant defense</strong>, it directly scavenges free radicals, elevates intracellular glutathione, and upregulates endogenous antioxidant enzymes via Nrf2 activation. Clinical studies confirm enhancement of measurable antioxidant defense markers, though overall evidence quality is rated low-to-moderate due to trial heterogeneity. Silymarin also supports <strong>hormone detoxification</strong> by stimulating Phase II detoxification pathways and upregulating liver detox enzymes relevant to hormone clearance. Traditionally, Milk thistle has been used for liver and gallbladder disorders for over 2,000 years, and it has historically been included in <strong>colon cleanse</strong> formulas for its hepatoprotective and bile-stimulating (cholagogue) properties. Emerging research also suggests potential benefits for <strong>cognitive health</strong> β€” a small 2020 human trial in adults with mild cognitive impairment reported improvements in memory and attention after 6 months of supplementation, though the evidence base remains predominantly preclinical.
siliymarin β€” 280 mg
Silymarin is the polyphenolic flavonolignan complex that comprises 65–80% of Milk thistle extract. It is not a single compound but rather a mixture of at least seven flavonolignans and one flavonoid (taxifolin), with silybin (silibinin) being the most abundant and active constituent. Research suggests Silymarin supports <strong>liver detox</strong> through robust clinical evidence: a 2023 systematic review of 29 RCTs found that 65.5% of studies reported reduced liver enzyme levels. It is used in Europe as an adjunct for alcoholic liver disease, drug-induced liver injury, NAFLD, and viral hepatitis. Its <strong>antioxidant defense</strong> is well-documented β€” a 2025 meta-analysis of 16 RCTs confirmed significant reductions in oxidative stress markers (MDA, CRP) and increases in antioxidant enzyme activity (SOD, GPx) following supplementation. For <strong>environmental toxin protection</strong>, Silymarin's purified component silibinin has documented clinical use as an antidote to Amanita phalloides mushroom poisoning, blocking hepatocellular uptake of amatoxins via competitive inhibition. It also shows hepatoprotection against drug-induced and chemotherapy-related liver toxicity in clinical trials. Additionally, Silymarin is the primary hepatoprotective bioactive studied for <strong>mycotoxin-induced liver injury</strong>, and it is specifically listed in authoritative reviews of chronic aflatoxin exposure mitigation strategies. For <strong>healthy aging</strong>, Silymarin activates Nrf2 and SIRT1 pathways, extends lifespan in model organisms, and has been recognized by the German Commission E for hepatoprotection β€” effects relevant to mitigating age-related oxidative damage.
dicalcium phosphate
Dicalcium phosphate is a Calcium-based compound commonly used as a tableting aid and excipient in supplement manufacturing. It provides structural integrity to tablets. Calcium is the most abundant mineral in the human body, with over 99% stored in bones and teeth as hydroxyapatite. While its primary role in this formulation is as a tablet base, Calcium participates in numerous physiological processes including muscle contraction, nerve transmission, and cellular signaling.

FAQ

Frequently asked questions

What is Silymarin and why is it important in uvora Milk thistle?

Silymarin is the primary active complex extracted from Milk thistle seeds. It is not a single compound but a mixture of flavonolignans β€” including silybin A and B, isosilybins, silychristin, and silydianin β€” plus the flavonoid taxifolin. Silymarin is the substance thought to have hepatoprotective effects in the body. This product is standardized to 80% Silymarin (280 mg per tablet), which means each tablet delivers a consistent, potent amount of the active complex.

What does 'time release' mean in this Milk thistle formula?

The time-release formulation is designed to slowly and consistently furnish Silymarin to the liver rather than delivering it all at once. This is relevant because Silymarin has a relatively short half-life β€” generally less than 4 hours β€” and undergoes rapid metabolism. A sustained-release format helps maintain a steadier supply of Silymarin throughout the day.

Are there side effects associated with Milk thistle?

Available evidence from clinical trials suggests that Milk thistle is generally well-tolerated. Side effects can include a laxative effect, nausea, diarrhea, abdominal bloating and pain, and occasional allergic reactions. Persons with hypersensitivity to Asteraceae/Compositae plants β€” such as chrysanthemums, daisies, ragweed, or marigolds β€” may have cross-reactive allergic sensitivity. If you have questions about whether Milk thistle is appropriate for you, our naturopath offers free consultations.

Can I take uvora Milk thistle with my medications?

Silymarin has been shown to have limited effects on the pharmacokinetics of several drugs at standard doses. However, it may decrease the activity of certain cytochrome P-450 enzymes and UDP-glucuronosyltransferase enzymes, so healthcare providers recommend caution when co-administering Milk thistle with narrow therapeutic window drugs. A recent study also suggested Milk thistle may increase systemic exposure of the anti-breast cancer drug raloxifene. Additionally, a mild blood sugar-lowering effect is clinically relevant when taken alongside antidiabetic medications. Always consult with your healthcare provider before combining supplements with prescription medications.

How much Silymarin does each tablet provide?

Each 350 mg tablet of Milk thistle herb extract consists of 80 percent Silymarin, which provides 280 mg of Silymarin per tablet. Since the recommended serving is 1 tablet twice daily, you receive 560 mg of Silymarin per day β€” falling within the dosage range commonly used in clinical research.

How long has Milk thistle been used for liver support?

Milk thistle has an exceptionally long history of use. Its therapeutic properties were first documented by the Greek physician Dioscorides around 40–90 AD. Ancient Romans and Greeks used the herb as a remedy for liver-related concerns, and during the Middle Ages herbalists prescribed it for jaundice and liver congestion. When Silymarin was discovered in fruit extracts and its protective effect on the liver was confirmed in scientific studies, the role of Milk thistle in therapy was reaffirmed. Today, the European Medicines Agency recognizes a 'well-established use' of Milk thistle for hepatoprotection, approved by 11 countries.
