Analysis

The label identifies both 290 mg of milk thistle seed extract and 185 mg of dried silymarin. That separation makes the active contribution easier to assess than a raw-herb weight alone.

A standard dry capsule does not provide a phytosome or other disclosed absorption-enhancing system. The relationship between the extract and silymarin entries could also be explained more clearly.

Adults seeking a focused, reasonably transparent milk thistle option are the best fit. People prioritizing absorption may prefer a phospholipid-bound silybin product.

Who is it for
  • Adults seeking clearly quantified milk thistle
  • People who prefer a focused single-herb capsule
  • Users prioritizing active-marker disclosure
Best for
  • Focused milk thistle supplementation
  • Clearly stated silymarin intake
  • Simple liver-support routines

Pros

  • States a separate silymarin amount
  • Provides a meaningful extract weight
  • Avoids unrelated active ingredients

Cons

  • No absorption enhancer is disclosed
  • Relationship between two entries is not fully explained
  • Conventional dry-capsule delivery

Warnings

  • Milk thistle can cause nausea, gas, or loose stools in some users.
  • People sensitive to ragweed-family plants may have an allergic reaction to milk thistle.
  • Milk thistle can affect drug-metabolizing pathways, which matters for medicines that require tightly controlled blood levels.

Nutrient quality

92 Highest impact

Milk thistle seed extract is paired with a separately stated silymarin amount, making active quality easier to judge. The disclosed silymarin amount is meaningful for focused milk thistle use.

.

Ingredient transparency

81 Highest impact

Active ingredients generally have stated amounts and no proprietary blend hides a dose. Serving counts are available, while full directions and the other-ingredients list are missing.

.

Customer satisfaction

64 Moderate impact

The supplied aggregate rating is strong and the rating volume provides some confidence in that metric. No comment-level evidence is available to assess recurring complaints or confirm how experience matches the intended purpose.

.

Value for money

96 Highest impact

Clear active potency and favorable serving value strongly support formula quality. The focused design and separately disclosed active amount compare very well within the category.

Milk Thistle · 290 mg

A substantial milk thistle seed extract with separately disclosed silymarin provides focused liver and antioxidant support. The active amount gives meaningful depth in a well-recognized hepatic-protection pathway.

The dry capsule lacks an absorption-enhancing delivery system, so silymarin uptake may be limited. The formula remains narrow and does not add glutathione precursors, methylation nutrients, or biliary-support cofactors.

Report overview
D+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyA+ Value

Separate seed-extract and silymarin amounts show a meaningful active dose from the preferred plant part. The dry capsule lacks technology to improve silymarin absorption. The low serving cost creates strong value despite the basic delivery.
