I’m a scientist, not your physician

I hold a PhD in nutritional biochemistry. I am not a medical doctor, and nothing on this website, in my newsletter or in my book is medical advice. It is not meant to diagnose, treat, cure or prevent any disease.

What I share is my own experience: the habits and protocols I developed for my own body, and the science that persuaded me. I am a study of one. Your body, your history and your medications are different from mine, so please don’t copy what I do. Talk to your own doctor before you change your diet, start a new exercise program, or take a supplement, especially if you are pregnant, take prescription drugs, or have a medical condition.

I mention studies, tests and products because they shaped my thinking, not because I endorse them for you. Science changes, and some of what I describe may be revised by newer research. You use this information at your own risk.

I don’t earn anything from the products, tests or companies I mention.

What I collect, and why

• Your email address, when you sign up for the free sample, my newsletter or the signed-copy list. I use it to send you what you asked for, and occasional letters about the book and my training.

• Your name and message, if you write to me through the contact form. I use them only to reply.

• Basic site statistics. Like most websites, this one counts visits and uses cookies so the pages work properly. These numbers are anonymous and show me which pages people read.

I never sell, rent or trade your information.

Who else handles it

This site and its mailing list are hosted by Squarespace, which stores your email address on my behalf. If I move my newsletter to another service, such as Substack, I will move the list with it and tell you in a newsletter first. Each of these companies has its own privacy policy.

Your choices

Every email I send has an unsubscribe link at the bottom; one click and you’re off the list. To see, correct or delete the information I hold about you, write to me at hello@linktovitality.com and I’ll take care of it.

Children

This site is written for adults. I don’t knowingly collect information from anyone under 18.

Changes

If I change this page, I’ll update the date at the top.
