Contact Chris Masterjohn, PhD

I am currently working full time on my book, which can be pre-ordered here, except for limited time devoted my consulting clients. You can book a consultation here.

While I am finishing my book, I do not have much time to respond to individual questions and cannot promise any answers. However, if you ask your question on social media, I may select it for an answer on YouTube live, which I do a few times a week if I can find the time.

Additionally, most months CMJ Masterpass members have the opportunity to ask questions in a live 2-hour Q&A. If you join and participate, you will get your question answered.

If you have a specific question on vitamins and minerals or on essential fatty acids, there's a good chance you can find the answer in my Vitamins and Minerals 101 Cliff Notes, so please purchase a copy for $2.99 if you haven't done so yet.

Technical Support and Product/Service Questions

For technical support, or for a question about purchasing a product or service I offer, please email my support team by adding “support” and “@” to the domain of my web site.

Please do not email my support team with specific questions about health and nutrition. Please save these questions for social media, Masterpass Q&As, or consultations.

Once I finish my book, I will be more available. I look forward to getting it into your hands and being more present out in the world!
