Broccoli Seed Extract Sulforaphane 0.1%-10% | Premium Natural Antioxidant for Supplement Manufacturing

Product introduction

Sulforaphane is a bioactive compound derived from glucoraphanin in broccoli seeds, created through enzymatic hydrolysis. Known for its bioactivity, sulforaphane’s stability and handling are vital to successful product formulation, as it is highly sensitive to environmental conditions. Joy-Natural provides sulforaphane with a controlled-temperature production process, validated HPLC quantification, and protected storage, ensuring minimal variability and optimal quality during formulation and scale-up.

Powerful Natural Antioxidant for Your Formulations

Sulforaphane is one of the most researched natural compounds for oxidative stress support. Derived from glucoraphanin in broccoli seeds through enzymatic hydrolysis, our sulforaphane delivers consistent potency and stability—trusted by nutraceutical manufacturers worldwide.

The Science Behind Sulforaphane

Discovered by researchers at Johns Hopkins University in 1992, sulforaphane has been the subject of 2,000+ peer-reviewed studies exploring its role in cellular health and antioxidant activity.

Our sulforaphane is produced under controlled temperatures to preserve its bioactive potency, with each batch validated via HPLC for consistent quality.

Applications

Daily Wellness Capsules & Tablets: Ideal for inclusion in supplements designed for everyday health support, especially in formulations aimed at enhancing antioxidant activity and overall vitality.
Premium Nutraceutical Formulas: Sulforaphane is widely used in high-quality nutraceuticals designed to support antioxidant balance and oxidative stress modulation.
Oral Liquids (Drops): Due to its sensitivity to light and temperature, sulforaphane can be used in controlled packaging formats, such as functional drops, to preserve its potency.
Softgels & Stabilized Formats: Ideal for RTM powders and gummies, especially in antioxidant-protected systems or softgel formulations that maintain stability.
