Vitamin D
Designed for a 60-second scan in primary care. Use this to explain why this theory fits, what would weaken it, and which tests are most worth discussing.
Why this still fits
I want to systematically evaluate whether Vitamin D is contributing to my brain fog and compare it against close alternatives.
What would weaken it
- -Does your pattern fit Vitamin D more consistently than Nutrient when timing, triggers, and recovery are compared side-by-side?
- -Does your pattern fit Vitamin D more consistently than Depression when timing, triggers, and recovery are compared side-by-side?
- -Does your pattern fit Vitamin D more consistently than Anxiety when timing, triggers, and recovery are compared side-by-side?
Key points to communicate
- •Please document what findings would confirm this cause versus lower confidence.
- •I want an evidence-first workup with clear follow-up criteria.
- •Please note which competing causes should be checked in parallel if results are inconclusive.
Tests and measurements to discuss
Need the fuller context? Use the test explainers for the measurement itself, or jump back to the tests section on the Vitamin D page to see how the tests fit the whole pattern.
