How much sulforaphane is actually produced by this product?

Its very suspicious to answer this question by stating you should call customer service. What are they hiding ? This is a blended compound that include components from mushrooms and also a Sulforaphane Glucosinolate compound. To get the actual amount of Sulforaphane, they have to remove the Glucosinolate and the mushroom component myrosinase. It takes alot of money to strip these components off and even more money to measure Sulforaphane. So there is no way they can actually tell you. So you are requested to call customer service so they can tap dance for you.

Have you checked the mushrooms for heavy metals? Mushrooms are a sink for heavy metals.

This is the product being utilized by john Hopkins cancer researches. Because of the stringent standards of government clinical studies, I believe that this must be a clean product

Approximately how much sulforaphane can be expected to be produced from a dose?

Avmacol Extra Strength has about 30 mg of glucoraphanin + myrosinase per tablet. This converts to sulforaphane at a 35% rate, meaning each tablet has about 10.5 mg of sulforaphane.

Because of the myrosinase being so fragile and unstable, wouldn’t it need to be refrigerated?

Thank you for your inquiry. Avmacol® Extra Strength tablets undergo accelerated and real time stability studies to ensure the products maintain full potency up to the expiration date when stored at the recommended storage condition.

Pretty good, but expensive.

Pretty good supplements. I believe they work well since my hs-CRP was very low. I take other supplements as well but I am sure this has contributed to the results as well. They are on the expensive side though, I don't think these are worth it without a discount or lower price.

Great product but competitor is better value

My dream Avmacol product would be a stripped down version, just broccoli extract (glucoraphanin) and mustard seed (or other source of myrosinase), in a coated tablet and/or in a foil blister pack. If an additional ingredient is needed for marketing, throw in some unstandardized broccoli to supports GR conversion in the colon. Let increased stability be the differentiation and not moringa or mushrooms. I’d take higher doses or larger quantity if it were in a coated tab or foil packaging.
