I realize that supplement intake must be tailored to individual’s body and there might be no silver bullet for it. But generally speaking, which supplements do you take on a daily basis? (I would be grateful if you could indicate dosage/brand)

      Rhonda, I recently started time restricted eating. I take Pure Encapsulations O.N.E as well as Throne Curcumin. Both of them are time released over 24 hours I believe. Will these interfere with time restricted eating?

      Thank you, John

        Anyone have any feedback on the new Glucoraphanin / Myrosinase supplement called Broc Sprout 2 ?

        Their site is found at https://www.brocsprout2.com/

          Hi Rhonda, my fiancee and I are taking USANA CellSentials Pack. Have you heard of this supplement? Here are the product details on their page:


          Here are the supplement facts:


          Your input would mean a great deal. I’m still on the fence if their product is any good, or if the company itself is legit. We’re from the Philippines by the way, and USANA has a strong multi-level marketing presence here. We get the product through distributors who are members.

          Thank you for your awesome work!

                    Hi Rhonda, I am highly interested in the benefits of sulforaphane. Do you recommend any supplements with sulforaphane in them? Thanks!

                    1. 1

                      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.

                      1. 1

                        Hi Rhonda, I’ve been following all your public material on Sulforaphane and love it. I live in Brazil but I go often to the US so I purchase the seeds there and sprout in Brazil. My mom is off to France today, she is 70 years old, and I told her to buy Prostaphane for her own consumption. Prostaphane markets themselves as a prostate supplement and for that reason I got a little nervous since she does not need any supplementation for prostate. All I want is for her to get the benefits of Sulforaphane. Having said that, Prostaphane is the way to go right, despite the fact that they market themselves as a prostate supplement. Thank you!!

                      Are broccoli seeds in my smoothie as effective as sprouts

                      1. 1

                        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…

                        1. 1

                          I’ve wondered this too, and seen the information from Dr. Fahey as well. From what I understand, soaking the seeds can activate enzymes that break down some antinutrients in a similar way as sprouting can. So I wonder if the same effect could be achieved by making the smoothie the night before, in effect “soaking” the seeds in whatever liquids are in the rest of the smoothie… I would be interested to know which antinutrients are in and/or specific to broccoli seeds, and whether soaking them could have similar benefits to sprouting them. This is really just a matter of time and convenience to me personally, but also curiosity.

                      2. 6

                        Hi Rhonda, what about for children? I have a four year old daughter and would like to know if flintstones are the way to go. Thanks ahead of time

                          Hi Rhonda!

                          Do you still think highly about Elysium? Is that something you have considered taking?

                          1. 1

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

                              @feynman: I recently covered this topic a bit on the Tim Ferriss Podcast #237, but here are a few things I usually supplement:

                              • omega-3 (4-6 pills depending on the brand)
                              • vitamin D up to 4,000 IU depending on time of year, sun exposure and recent test value (I shoot for 40 to 60 ng/ml).
                              • a multivitamin, usually Pure Encapsulations
                              • a vitamin K2 MK7 supplement
                              • … and a few other things which are covered in that podcast as well as the brands I prefer.

                                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.
