THORNE Broccoli Seed Extract - Supports Liver Detoxification & Antioxidant Protection - 60 Capsules

Key Benefits for Liver Health and Antioxidant Support

Your liver works hard every day to remove toxins from your body. THORNE Broccoli Seed Extract is formulated to support this essential role by boosting phase II detoxification pathways. The active compound, sulforaphane glucosinolate (SGS), stimulates your body's own antioxidant defences, including glutathione production. Added vitamin C further supports immune function and collagen synthesis. Together, these ingredients help combat oxidative stress and maintain overall wellbeing.*

What Is THORNE Broccoli Seed Extract?

THORNE Broccoli Seed Extract is a targeted food supplement designed to enhance the body's natural detoxification and antioxidant systems. It delivers a concentrated dose of SGS sourced from broccoli and kale seeds, plus myrosinase enzymes from mustard seeds to aid conversion into active sulforaphane. This unique combination helps activate internal antioxidant pathways, offering sustained protection against free radical damage.

What Makes This Broccoli Seed Extract Different?

Not all broccoli seed extracts are created equal. THORNE's formula stands out for several reasons:

• Dual-source SGS: Extracts from both broccoli seeds and kale seeds provide a broad spectrum of glucosinolates.
• Optimised bioavailability: The inclusion of mustard seed powder supplies naturally occurring myrosinase, an enzyme that converts glucosinolates into active sulforaphane, ensuring your body can use it effectively.
• Third-party certification: Every batch is tested to confirm potency and purity, so you know exactly what you're getting.
• Trusted brand: THORNE is the #1 most recommended clinical supplement brand by health care practitioners (based on a 2026 independent survey) and is used by over 100 professional sports teams.

How to Incorporate Broccoli Seed Extract into Your Routine

For best results, take two capsules daily with food. The presence of mustard powder may cause a slight warming sensation; this is normal and indicates active enzymes. This food supplement is suitable for adults wishing to support liver function, boost antioxidant defences, or fill nutritional gaps. As with any supplement, consult your health care provider before starting a new regimen, especially if you are pregnant, nursing, or taking medication.

FAQs About Broccoli Seed Extract

What is sulforaphane glucosinolate (SGS)?

SGS is a naturally occurring compound found in cruciferous vegetables such as broccoli and kale. It is a precursor to sulforaphane, a potent antioxidant that activates the body's own detoxification enzymes.

Why is myrosinase important?

Myrosinase is an enzyme that converts glucosinolates into active sulforaphane. Without sufficient myrosinase activity, absorption can be limited. THORNE includes mustard seed powder to provide this enzyme naturally.

Can I take this on an empty stomach?

While it can be taken at any time, taking it with food may improve digestion and reduce any potential stomach sensitivity from the mustard seed. If you experience a warm sensation, it is a sign the enzymes are active.

Is this product third-party tested?

Yes. THORNE Broccoli Seed Extract is third-party certified to ensure the ingredients match the label and that the product is free from contaminants.
