About Product

Silymarin, a flavonoid complex extracted from the seeds of Milk Thistle, has been used medicinally for centuries, most commonly for the treatment of liver and gallbladder disorders.* Silymarin/Milk Thistle is the subject of more than 80 clinical studies registered with the US National Institutes of Health.

Silymarin, like all herbal extracts, in natural form is poorly absorbed by the body to offer clinical benefits. It must be modified or formulated. Making Silymarin bioavailable is particularly challenging.


Silymarin consists of two primary and most active compounds known as silybin A & B. When taken orally, silybin takes many hours for the body to absorb in the gastrointestinal tract,

and meanwhile a lot of it is excreted out in bile and urine. In its natural form, Silymarin thus cannot clinically deliver health benefits. Silymarin is also known as Milk Thistle because of the milkly sap in the leaves of the plant,

which is indigenous to the Mediterranean region and now grown in many parts of the world.


Manufacturers have developed proprietary and patented formulations and techniques to convert silybin into highly absorbable forms. The methods include combining isolated silybin with other molecules; encasing it into the structure of another molecule and safely delivering it to target liver cells; converting it into soluble derivatives; breaking silybin into “nano” size particles; and formulating it into tablets that can float in the stomach and slowly release the active compounds over time.

The increased absorption has shown to augment bioavailability 3 to 30 times the normal silybin, depending on the reformulation and the delivery mechanism. The higher the bioavailability, the lower the dose required to obtain therapeutic value.


Not all of the techniques and reformulations have been successfully deployed. As a result, Silymarin products in the market vary widely in solubility and bioavailability.


Only lab analysis can cofrm the solubility and bioavailability of the product. The acceptable standards are well established in the U.S. Pharmacopeia (USP) and the British Pharmacopeia (BP).


And the test method itself is important: HPLC (high-performance liquid chromatography) is more accurate than the less sensitive UV (Ultraviolet) Spectroscopy, which can exaggerate the solubility measure.

The solubility and bioavailability facts are generally not mentioned on the product label. It is up to the consumer to inquire about these critical measures of Silymarin quality, including the test method used to analyze the product.


Facts about the brand

Samarin contains high grade of Silymarin manufactured at a GMP facility.

Samarin has been tested by an independent lab showing its soluble silymarin content is on average 105.8% of the product's label claim, in compliance with US Pharmacopoeia (USP 38) specifcations.

Samarin has been tested by an independent lab demonstrating it dissolves twice the rate of some leading brands.

Samarin has been tested by an independent lab confrming that 98.5% to 101.5% of the label amount dissolves in 45 minutes, signifcantly higher than the 75% minimum established as the US Pharmacopoeia's most recent standard (USP 38).

All tests of product quality were perfomed with HPLC and in accordance with standardized test methods.
