Hi there,

A quick welcome to everyone who joined from YouTube this week, whether you came for the Heart-Test Map or the Supplement Stack. Both guides are linked at the end of this note.

Creatine gives me insomnia.

I still recommend it.

This basically sums up supplement advice, and much of medicine.

The evidence can be good. The intervention can still be wrong for any one person.

For personal and professional reasons, I have tried dozens of supplements myself and recommended many to others.

New evidence changed my guidance. So did results I've seen in myself and my patients.

Three supplements have changed my advice. The same evidence can lead to different choices for different people.
