Method: Shotgun metagenomic sequencing (CLIA 21D2062464); not cleared or approved by the FDA. Results reflect relative microbial abundance for wellness education purposes. Not intended to diagnose or treat disease and not a substitute for clinical consultation. Microbial associations are based on emerging scientific research and may change over time. Derived from laboratory results. This score or index is not an FDA-cleared test. It aids clinician-directed assessment and is not a stand-alone diagnosis.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Vitamin B9 testing
- Gut microbial folate production capacity tracking
- microbiome-derived folate contribution assessment
What is Vitamin B9?
This metric estimates your gut microbiome's functional capacity to synthesize folate (vitamin B9), derived from folate biosynthesis pathway gene abundance by shotgun metagenomic sequencing.
Why is Vitamin B9 important?
Gut bacteria can produce folate, and unlike B12, some evidence suggests gut-produced folate may be partially absorbed in the colon. Microbiome folate production capacity may contribute to overall folate status, particularly relevant for members with borderline dietary folate intake.
What insights will I get?
Your microbial folate production capacity is one component of a comprehensive folate status assessment. It should be interpreted alongside dietary intake and blood folate measurements to understand your overall folate picture.
