From Broccoli to Biochemistry: How Sulforaphane Supports Your Body

Sulforaphane is a result of two specific compounds:

Glucoraphanin, found in broccoli seed and sprout extract

Myrosinase, a natural enzyme that activates glucoraphanin

What is Glucoraphanin?

Glucoraphanin, also known as sulforaphane glucosinolate, is a compound that is present in many cruciferous vegetables, most notably in broccoli. It is an essential ingredient needed for sulforaphane production because it is sulforaphane’s direct precursor. The glucoraphanin is converted into sulforaphane after it is processed by an active myrosinase enzyme.

What is Myrosinase?

Myrosinase is an important enzyme required to convert glucoraphanin into sulforaphane. Additionally, it can be found in cruciferous vegetables, though it can become inactivated during the cooking process.

The Importance of Active Myrosinase Enzyme

The conversion of glucoraphanin to sulforaphane can be expressed in this simple equation:

Active myrosinase enzyme is essential for the conversion of glucoraphan into sulforaphane. Without this enzyme, it may not be possible to reap sulforaphane's many health-promoting benefits, which is why you’ll always find Myrosimax® (Active myrosinase Enzyme) in the Avmacol® brand family.Even though it is true that both glucoraphanin and the myrosinase enzyme can be found in cruciferous vegetables such as broccoli, Brussels sprouts, and cauliflower, there may not be enough of either compound to allow for adequate sulforaphane production. This can be due to seed quality, soil composition, and many other factors. Additionally, the myrosinase enzyme can be destroyed during the cooking process. So while both glucoraphanin and the myrosinase enzyme can be found in the vegetables you eat, the ones you buy from the market are not reliable sources of either compound.The Avmacol® brand contains both glucoraphanin and Myrosimax® (Active Myrosinase Enzyme), the essential ingredients needed to promote sulforaphane production.*

Customer reviews

I have been using this product for the past couple years - great way to get the benefits of broccoli sprouts without the hassle of germinating yourself. Recently I switched to Amazon vs. ordering direct to take advantage of subscribe and save.

The quality and taste seem to be okay and easy to swallow. No noticeable smell and the value for the money is good. Quality ingredients. I genuinely seem to feel better and no its not just a placebo. Like anything with supplements, you will notice more of a significant difference with time.

Just look up the research papers on Avmacol if you are not convinced. This is the best product but my only concern is the fact that it’s such an unstable product and shipping it in the summer heat may be deleterious to the product.
