Frequently Asked Questions (FAQ)
What is Broccoli Seed Extract?
Broccoli Seed Extract is a concentrated natural ingredient obtained from the seeds of Brassica oleracea var. italica. It is highly valued for its rich content of bioactive health-promoting compounds, primarily glucoraphanin and sulforaphane.
What is the difference between Sulforaphane and Glucoraphanin?
Glucoraphanin is a stable precursor compound (glucosinolate) found naturally in broccoli. When digested or exposed to the enzyme myrosinase, it converts into Sulforaphane, which is the active, highly bioavailable antioxidant compound.
What specifications do you supply for Broccoli Seed Extract?
We offer standardized Broccoli Seed Extract with Sulforaphane content ranging from 1% to 10%, and Glucoraphanin content ranging from 1% to 13% to meet various formulation requirements.
What are the primary health benefits of Sulforaphane?
Sulforaphane is a potent activator of the Nrf2 pathway, which triggers the body's natural antioxidant defense mechanism. It supports cellular detoxification, cardiovascular health, immune function, and normal inflammatory responses.
How should Broccoli Seed Extract powder be stored?
To maintain its stability and potency, the extract should be stored in a cool, dry place inside tightly closed containers. Keep it away from direct sunlight, moisture, and excessive heat.
