Analysis

Indole-3-carbinol is supplied at a substantial amount and defines the formula's main purpose. Rosemary leaf extract adds complementary diterpenes, with carnosol and carnosic acid specifically named.

Naming the plant part and markers improves transparency over plain rosemary powder. No percentage standardization or extraction method is provided, so exact marker delivery remains unknown.

A single capsule and large count support convenient use. People wanting only rosemary can find a more focused product without the hormone-metabolism-oriented companion ingredient.

Who is it for
  • Adults seeking indole-3-carbinol with rosemary
  • Users who value named rosemary diterpenes
Best for
  • Combined I3C and rosemary routines

Cons

Nutrient quality

90 Highest impact

The rosemary extract names carnosol and carnosic acid, while complete marker percentages and extraction details are missing. Both indole-3-carbinol and rosemary reach meaningful combination-formula amounts.

.

Ingredient transparency

81 Highest impact

Active amounts are stated and no proprietary blend hides a core dose. Missing excipient details and complete use directions leave the supplied label information incomplete.

.

Customer satisfaction

64 Moderate impact

The supplied aggregate satisfaction average provides a broad signal, while the response volume determines how stable it appears. No comment-level evidence is available to assess repeated complaints or confirm intended-use experiences.

.

Value for money

76 High impact

The formula offers mixed but reasonable serving value. Both listed actives have a clear role without obvious padding.

C Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyB- Value

Named carnosol and carnosic acid markers make the rosemary extract more informative than plain leaf powder. The 50 mg amount is clearly separated and reaches the stated target for a combination formula, though extraction and marker percentages remain undisclosed. Serving-level value is reasonable for a formula that also provides a substantial amount of indole-3-carbinol.

Meta I 3 C

Metagenics
<p>The formula may offer a stronger or more clearly defined ingredient approach because it pairs 150 mg of indole-3-carbinol with rosemary extracts that name carnosol and carnosic acid. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, the supplied data do not state marker percentages or extraction details, so standardization remains incomplete.</p>
82 Performance

Optimized Broccoli and Cruciferous Blend

Life Extension
<p>The formula may offer a stronger or more clearly defined ingredient approach because it combines substantial broccoli extracts, myrosinase, DIM, watercress, and 100 mg of marker-focused rosemary extracts. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, its specialized cruciferous design is less suitable when a simple rosemary supplement is the goal.</p>
69 Performance

GABA Brain Food

NS Natural Stacks
<p>The formula may offer a stronger or more clearly defined ingredient approach because it provides 333 mg of rosemary leaf extract naming rosmarinic acid, plus substantial GABA and citrulline. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, marker strength is unclear, and the high serving cost is difficult to justify unless the stress-focused ingredients are wanted.</p>
75 Budget

St. John's Wort 300 mg

Nature's Way
<p>The lower-cost serving still provides a substantial standardized Saint John's wort extract with 80 mg of rosemary and 40 mg of spirulina. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, saint John's wort can interact with many medicines and may increase sun sensitivity, so the low cost does not suit everyone.</p>
84 Budget

Rosemary Extract 500 mg

Swanson Superior Herbs
<p>The lower-cost serving still provides 500 mg of rosemary extract and names rosmarinic acid. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, marker percentage, plant part, and extraction method are not provided, which limits standardization detail.</p>
80 Budget

Triple Action Cruciferous Vegetable Extract

Life Extension
<p>The lower-cost serving still combines 400 mg of broccoli concentrate, indole-3-carbinol, DIM, watercress, and 100 mg of rosemary extracts with named diterpenes. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, the multi-ingredient cruciferous design is more specialized than a simple rosemary product.</p>
78 Value

Rosemary 400 mg

Swanson Premium Brand
<p>Value may improve because the lower-cost serving provides 800 mg of rosemary as a focused whole-herb formula. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, it lacks extract concentration and active-marker standardization, making potency less predictable.</p>
77 Value

Triple Action Cruciferous Vegetable Extract with Resveratrol

Life Extension
<p>Value may improve because the lower-cost serving adds modest resveratrol to a substantial broccoli, indole-3-carbinol, DIM, watercress, and marker-focused rosemary blend. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, the added resveratrol has limited purity detail and does not materially simplify the formula.</p>
77 Value

Pycnogenol 50 mg

Nature's Way
<p>Value may improve because the lower-cost serving combines natural vitamin E, 50 mg of maritime pine extract, and 50 mg of rosemary. Compared with the original combines indole-3-carbinol with marker-named rosemary extract, rosemary is not an extract and has no marker detail, limiting its contribution to the antioxidant formula.</p>
