I noticed a post from a few years ago where a member's partner found improvement with cognition and reduction in headaches from a low daily dose of creatine. There was some scepticism expressed in the replies which appears to have been unfounded.
Andrew Huberman released a podcast on headache management in February 2023 that includes a long section on the use of creatine in the management of post-concussion headaches, cogntion and fatigue.
Rather than detail the suggested protocol I'll link to the section in his podcast and the paper he based his interpretation on so anyone interested can draw their own conclusions. The paper was published in 2008 and was a small pilot with children under the age of 18 who had been hospitalised due to TBI.
Podcast Title:
How to Stop Headaches Using Science-Based Approaches
