Super Digestible - April 2025 ✅

You monthly nutrition science cheat sheet.

What is Super Digestible?

Every day I post a research breakdown of the latest nutrition science related to human performance, health and the power of food. The daily 1-min reads are a great way to stay on top of the research. But, I want to make actionable summaries even more accessible 📝

Therefore, I started Super Digestible, a monthly newsletter containing a one-to-two sentence summary of each study I’ve reviewed that month. Focusing specifically on how you can apply these findings in your own practice ✅

Each study will be filtered into: DO, CONSIDER, DON’T. Based on the research findings, paired with my professional experience in the world of elite sport 🏆

This is your monthly research cheat sheet, so you can stay at the very pinnacle of science-based performance nutrition 🏔

A huge shoutout to

Daniel Rowland

✅ DO these things…
