Analysis

Using milk thistle seed is relevant because this plant part contains the silymarin complex. The substantial extract weight and lack of unrelated actives keep the formula purposeful.

The label does not disclose a silymarin percentage or calculated active amount. A conventional dry capsule also lacks a stated carrier or delivery system intended to improve absorption.

Organic sourcing may matter to shoppers with that preference, but it does not establish active potency. The product fits buyers who value source and simplicity more than dose precision or lowest cost.

Who is it for
  • Adults who prefer organic botanical extracts
  • People seeking a single-herb capsule
  • Buyers who value disclosed seed sourcing
Best for
  • Organic milk thistle routines
  • Minimalist supplementation
  • Focused liver antioxidant support

Pros

  • Organic extract
  • Seed source is identified
  • Substantial single-herb amount

Cons

  • No silymarin percentage
  • Dry capsule lacks delivery support
  • Value is only moderate for the detail provided

Warnings

  • Milk thistle may cause nausea, gas, or loose stools in sensitive users.
  • People allergic to ragweed, daisies, or related plants may also react to milk thistle.
  • Milk thistle may affect blood-sugar control; people using insulin or glucose-lowering medicine should check with their prescriber.

Nutrient quality

77 High impact

Organic seed sourcing and a focused single-active design are meaningful strengths. Unknown active yield and basic delivery limit confidence in dose quality.

Ingredient transparency

79 High impact

The plant part, organic status, and total extract amount are clearly identified. Active yield, usage, and excipient details remain missing.

Value for money

58 Moderate impact

Organic seed sourcing and a filler-free design provide some premium value. High serving cost and unverified potency weaken category competitiveness.

Milk Thistle · 375 mg

Milk thistle extract directly supports hepatocyte protection and is supplied at a substantial weight. The label does not disclose a silymarin percentage, so active potency cannot be confirmed.

The single-botanical formula provides moderate depth for liver protection but no conjugation, antioxidant recycling, or biliary cofactors. Its focused design is clean and coherent.

D- Active Ingredient Quality & BioavailabilityF Dose, Safety & Label TransparencyF Value

The organic seed extract uses the plant part richest in silymarin, which is a meaningful quality strength. Its silymarin percentage and active yield are not stated, and the dry capsule lacks enhanced absorption. The above-median serving cost is difficult to justify without clearer potency.
