I'm searching for best sulforaphane brands and it comes down to Avmacol and Prostaphane but then I came across comments suggesting release of a sulforaphane product in upcoming months by ND.
I cannot decide, should i wait for it or go for above brands?
I'm considering it for Brain fog and lethargy.

Even Prostaphane? It claims to contain stabilized free form of sulforaphane.

Prostaphane is what was being used in Broq prior to their recent reformulation. We had a call with the French company that makes it, the Olga group, and they said it is stabilized for normal temps, but breaks down over 75 degrees Fahrenheit. We informed them that Amazon warehouses are never kept at 75 degrees in the summer here, and that most of the sulforaphane was likely breaking down with the bottles sitting in the warehouse waiting to be shipped. I told them they should probably buy some Amazon and run them through the lab. They sounded concerned with that on our call, and said they would look into it. Then suddenly Broq is no longer using Prostaphane, and is being reformulated with a standard glucoraphanin source with myrosinase. I never got direct confirmation from them that our warnings caused them to lab test it showing it was not stable in normal US warehouses, but I read between the lines on it. They told us that even at normal room temps it degrades fairly quickly. Taking sulforaphane and trying to stabilize it with different strategies just doesn't seem like a good solution. It's best to have stable glucoraphanin in the supplement, then convert it to sulforaphane right before you consume it. That's how we have been able to get insanely high amounts of bioavailable sulforaphane in our formula.
