What’s inside this formula?
Thorne’s Broccoli Seed Extract is listed here in the broccoli seed extract collection. This article looks at the selected 60 capsules — US label pack, then puts its ingredients into context.
Per 1 capsule: Vitamin C (as Ascorbic Acid) 100 mg; Mustard Powder (seed) 145 mg; Sulforaphane Glucosinolate (from Broccoli extract (seed) and Kale (seed)) 50 mg.
Check the original label ↗Broccoli seed extracts may contain glucoraphanin, a precursor that can be converted into sulforaphane. Conversion depends partly on the enzyme myrosinase and on digestion. An extract weight, a glucoraphanin amount and an actual sulforaphane amount therefore describe different things; comparing them as equivalent doses can be misleading.
The pack details above come from the manufacturer. Ingredient research below does not establish the effects of this exact product or independently verify its contents.
The complete declared ingredient amounts
The current table uses a serving of 1 capsule. It declares Vitamin C (as Ascorbic Acid) 100 mg; Mustard Powder (seed) 145 mg; Sulforaphane Glucosinolate (from Broccoli extract (seed) and Kale (seed)) 50 mg. These are manufacturer label amounts, not a personal dosing instruction.
The comparison detail that changes the decision
The 50 mg declaration is sulforaphane glucosinolate from broccoli and kale seed, not 50 mg preformed sulforaphane. Mustard seed supplies a separate component. The selected product has 60 labelled servings per container. Matching ingredient form and serving matters more than bottle count.
Excipients, cautions and evidence limits
Other listed ingredients: Calcium Laurate, Hypromellose (derived from cellulose) capsule. The manufacturer identifies mustard-derived myrosinase. Mustard allergy and ingredient tolerance matter; this product is not a cancer-prevention or detoxification treatment. No independent batch test or exact-formula clinical outcome was verified in this review. Current Indian stock and delivered price remain unverified.
Where might it be useful?
A source of plant compounds
These extracts provide selected broccoli-derived compounds in a concentrated format.
Formulation affects exposure
Human bioavailability studies show that preparation and enzyme availability can influence sulforaphane exposure.
What the research can — and cannot — tell us
Studies measuring absorbed sulforaphane or its metabolites show that formulation matters. These are not the same as trials showing fewer illnesses, longer life or clinical “detoxification.” Results from a tested sprout beverage or enzyme-treated extract do not establish a benefit for every seed-extract capsule.
What deserves your attention?
The manufacturer identifies mustard-derived myrosinase. Mustard allergy and ingredient tolerance matter; this product is not a cancer-prevention or detoxification treatment.
Suitability comes before strength
Check whether the label specifies glucoraphanin, sulforaphane and myrosinase, and avoid assuming a conversion rate. Discuss concentrated extracts during pregnancy, medical treatment or persistent digestive symptoms; ordinary vegetables remain a useful dietary choice.
Dietary details for this product
Dietary status not confirmed The reviewed current label does not explicitly establish vegan or vegetarian status for the complete formula. A cellulose capsule or dairy-free statement alone is not a whole-formula declaration.
A dietary label and an allergy assessment answer different questions. Check every ingredient, the capsule or softgel materials and the allergen statement on the pack you receive. If you take medicines, have a health condition, are pregnant or are choosing for a child, discuss the full formula with a qualified clinician.
Make the comparison meaningful.
- Match the exact version.Look for Thorne · Broccoli Seed Extract and the 60 capsules — US label pack. A similar name or bottle can contain a different strength, blend or serving.
- Compare like with like.Read the serving size alongside the active ingredient amount. Capsule count, compound weight and total blend weight can describe different things. Use the label notes above to see what matters for this formula.
- Check the seller and final cost.Review seller identity, expiry, batch details and any Indian import information. Compare the final delivered price only after matching the formula. Prices and stock are checked on the retailer’s site.
