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 B2 testing
- Gut microbial riboflavin production capacity tracking
- microbiome energy metabolism support assessment
What is Vitamin B2?
This metric estimates your gut microbiome's functional capacity to synthesize riboflavin (vitamin B2), derived from riboflavin biosynthesis pathway gene abundance by shotgun metagenomic sequencing.
Why is Vitamin B2 important?
Riboflavin is critical for cellular energy production (it is a cofactor in FAD and FMN). Gut bacteria produce riboflavin, and some of this production may be absorbed. Microbiome riboflavin production capacity may partially support overall riboflavin status.
What insights will I get?
Your microbial riboflavin production capacity is one element of your overall B2 status picture. It should be interpreted alongside dietary riboflavin intake and, if clinically indicated, blood riboflavin levels.
