I write about harnessing the power of nutrients.

I combine my scientific expertise with out-of-the-box thinking to translate complex science into new, practical ideas that you can use to help yourself on your journey toward vibrant health.

I stand for free speech, bodily autonomy, and medical freedom.

I stand for food sovereignty and the right to farm.

The other tabs provide features available to Masterpass subscribers.

Masterpass Membership

Here is a rundown of what you get when you become a Masterpass member.

Premium Posts and eBook Guides

Premium posts are highly actionable content that will contribute to future digital products offering guidance on specific health issues. These guides are available for purchase to anyone, and are freely available to Masterpass members once they come out. You can see previews of the premium posts here, and you can see the collection of ebook guides here.

Live Q&A Sessions

Live Q&A sessions occur over Zoom. You can ask your question anonymously in text, but you can also ask it publicly, and you can even get "on stage" and share your mic, web cam, or screen with everyone.

As a Masterpass member, you'll get access to the recording and transcript whether you had a seat in the session or not.

Most Q&A sessions alternate between Monday and Wednesday and between 10:00 AM and 6:00 PM Eastern to try to accommodate people in different time zones.

See when the next Q&A session is here.

Instructions for question submission and attendance are sent out by email ahead of the session, and are also linked to directly on the Q&A page, visible once you sign up.

Masterpass Forum

This is a private forum in the form of Substack comment threads where Masterpass members can ask questions or start discussions with one another. I participate several days a week.

Courses and Premium Features on Public Content

These features are currently being migrated from the Masterpass’s previous interface and should be ready by the end of May.

These include the following:

✅ Masterclass With Masterjohn: Energy Metabolism: 39 lessons on how we utilize food for energy, emphasizing biochemistry and the implications for how we eat. Videos are public, but you get exclusive access to transcripts, slides, references, further reading materials, and comment sections. 

✅ Masterclass With Masterjohn: the Antioxidant System: 12 lessons on how the antioxidant system works, and how protein, vitamins, and minerals fit in. Videos are public, but you get exclusive access to transcripts, slides, references, further reading materials, and comment sections. 

And premium features on public content:

✅ Transcripts! You get transcripts of my public podcasts that are only available to Masterpass members. These are great if you like to read, or if you want to be more productive. For example, I would first listen to the episodes while I'm doing something else to scan for familiarity, then I'd go back later and keyword search the transcripts for the things I found most interesting so I could follow them up by taking notes or reviewing them in more detail.

Exclusive Discounts

This includes 30-50% off pre-orders of my Vitamins and Minerals 101 Book, $50 off each hour of consulting with me, a dedicated storefront with an immediate 35% off 305 brands of supplements, and a rebate program where we top off your coupons by sending you back our affiliate commissions as rebates on all my favorite products as well as member-requested products.
