UltraThistle® Comparison Chart


The daily recommended dosage for UltraThistle® contains 360 mg of silybin, the most beneficial active ingredient in milk thistle. The chart below will show how many capsules of each competitor's product is needed to equal the 360 mg of silybin contained in just 3 capsules of UltraThistle, taken daily. It will clearly demonstrate how potent, convenient and cost effective UltraThistle is as compared to its competitors.

Facts to Remember:

  1. Milk thistle extract (silymarin) is made up of both active and inactive ingredients in varying amounts, with the active ingredients providing all of the supplement's benefits and therapeutic value. When purchasing a standardized milk thistle extract, you know exactly how much of the active ingredients you are receiving in every tablet or capsule. When purchasing a non-standardized milk thistle product, you have no way of knowing what proportion of active to inactive ingredients will be present in the final product. Even thought it might seem like a great value to purchase ninety, 1,000 mg capsules of milk thistle extract for only $9.00, you don't know how much of the active ingredient, if any, you are receiving. You could be throwing your money away.

  2. UltraThistle® provides a patented, highly-absorbable, standardized form of milk thistle that delivers up to 10 times more of milk thistle’s most beneficial active ingredient, silybin, to your liver.

Comparison based on 360 mg of silybin in UltraThistle® vs. 360 mg of milk thistle standardized to 80% silymarin.

Chart Notes:

  1. Standardized to 80% silymarin — The active ingredients of milk thistle (known collectively as silymarin) make up 80% of the total milligrams of the standardized milk thistle product. Therefore, if you purchased a 360 mg milk thistle product standardized to 80% silymarin, you would actually only have 288 mg of the active ingredients (360 mg x .80% = 288 mg).

  2. Silymarin contains only 50% silybin, the most beneficial of the active ingredients and responsible for the majority of milk thistle's liver-protective qualities. To continue the example above, a standardized milk thistle product containing 288 mg of silymarin only contains 144 mg of silybin (288 mg x .50% = 144 mg). So out of the original 360 mg of standardized milk thistle that we started with above, only 144 mg are silybin. UltraThistle has a daily dosage of 360 mg of silybin. Therefore, UltraThistle® contains over 2x the amount of silybin found in an equivalent amount of a standardized milk thistle product.

  3. UltraThistle's patented ingredient is 10x more absorbable — meaning you're getting 10x LESS silybin absorbed by your body with just a standardized milk thistle!
