There’s a few out there. Sulforaphane expert Dr. Jed Fahey mentioned in the podcast we did together that three brands stuck out as having what they say they did: Avmacol, Thorne, and Prostaphane.

I think Prostaphane is one of the most interesting, because this is a stabilized form of actual sulforaphane that comes in 10mg tablets and has been used in clinical trials. The real deal not a precursor. The problem is that it is French and not available in the United States! I would love to see this product in the U.S. Maybe you guys can inform them of American demand for their product and make it happen: [email protected].

If you don’t mind taking the precursor (glucoraphanin), Thorne is a great brand. It is glucoraphanin only, however. You can combine non-myrosinase containing supplements like Thorne’s product with a source of myrosinase like mustard powder or by consuming fresh cruciferous vegetables and it probably enhances the effects.

Finally, there is also Avmacol which adds in myrosinase. The amount of actual net sulforaphane you get from these products, however, can be affected by endogenous myrosinase activity. The amount of mg of actual sulforaphane you get when it’s all said and done, however, makes it cost prohibitive and less practical.

Dr. Jed Fahey clarifies in his frequently asked questions on the Chemoprotection Center website that broccoli seeds, despite having very high glucoraphanin and myrosinase content on a per gram basis, contains certain anti-nutrients… the effect of ingesting a lot of may not really be well understood yet.

Here’s the notable section from the FAQ…

Q: Can I eat whole broccoli seeds?

A: We are less prepared to answer this question because there may be complicating factors and because little research has been done to address this question. Certainly eating various types of seeds is practice that has been common to humanity since early in evolution when we were hunter-gatherers. Broccoli seeds are bitter if eaten raw, and they taste nutty and pleasant if lightly baked first. Since broccoli seeds – or sprouts for that matter – were never consumed prior to our discovery published in 1997, we do not know how much is too much. Broccoli seeds are loaded with GR (and with myrosinase, but that gets inactivated when you bake or cook the seeds). They also have other oils and indoles and compounds that could be anti-nutritional and undesirable if eaten in large quantities.

For now, it may be prudent to stick to sprouting since, as a result of the sprouting process, these anti-nutrients are used up during the sprouting process. It’s also a form a rich source of sulforaphane that’s been more studied.

Here’s the longer interview with Dr. Jed Fahey for those that haven’t seen it. A great deep-dive on sulforaphane and other isothiocyanates…

Not necessarily Elysium (I am not loyal to that brand specifically)… but yes to Nicotinamide Riboside in general.

Rhonda, are their any particular supplements you know of that have been proven to increase testosterone levels? I take Zinc, Magnesium, a multivitamin, vitamin D, omega 3 fish oil and ashwagandha root.
