Analysis

Freeze-dried broccoli and green bean provide the largest ingredients at roughly a gram each, with additional broccoli bringing the total cruciferous content higher. Cilantro and milk thistle each contribute 310 mg, creating a recognizable greens and liver-support theme.

The whole-food format preserves a simple formulation but does not provide standardized sulforaphane or silymarin yields. Protein and minerals are present only in food-level amounts and should not be treated as primary benefits.

Individual ingredient quantities are clear and 35 servings offer a practical supply. The supplied data do not include inactive ingredients, contaminant testing, or active-marker assays, which limits assessment of consistency and purity.

Who is it for
  • Adults seeking a whole-food greens powder
  • People who prefer freeze-dried vegetables over concentrated extracts
  • Users wanting broccoli, cilantro, and milk thistle together
Best for
  • Adding freeze-dried greens to a routine
  • Whole-food botanical supplementation
  • General greens support rather than high-potency extracts

Pros

  • Provides gram-level freeze-dried broccoli
  • Includes over a gram of green bean
  • Lists each whole-food amount
  • Uses a simple food-based formula

Cons

  • Milk thistle silymarin is not standardized
  • Broccoli active yield is not stated
  • Only 1 g protein
  • Purity testing is not disclosed

Warnings

  • Milk thistle may trigger reactions in people sensitive to ragweed-family plants
  • Broccoli, green bean, and cilantro are concentrated food ingredients and should be avoided by anyone allergic to them
  • The 85 mg potassium amount should not be relied on for potassium supplementation

Nutrient quality

76 High impact

Freeze-dried whole foods preserve a recognizable food-based format. Broccoli is substantial, while milk thistle is modest and unstandardized.

Ingredient transparency

77 High impact

Every listed ingredient has a clear amount and no blend hides doses. Missing standardization, directions, and excipients leave potency and practical use incomplete.

Customer satisfaction

67 High impact

The supplied average is very strong and the review volume is substantial. No firsthand details establish taste, mixing, tolerance, or perceived purpose fit.

Value for money

64 Moderate impact

Food-based processing and a substantial broccoli amount provide moderate quality value. Unstandardized milk thistle and uncertain active yields limit competitiveness for targeted liver support.

Milk Thistle · 310 mg

Broccoli and milk thistle offer plausible support for conjugation enzymes and liver protection. Broccoli is present in a food-like amount, while milk thistle is modest and not standardized.

Most ingredients are whole freeze-dried foods without standardized active yields, so evidence and potency are uncertain. The green-food combination is compatible and has a recognizable detoxification theme.
