Carbon Dioxide (CO2)

Carbon Dioxide (CO2) is a electrolytes &minerals biomarker that Measure of blood acidity The normal reference range is 23-29 mEq/L. Regular testing helps track changes and identify potential health issues early.

9 out of 10 major blood testing providers include Carbon Dioxide (CO2) in their standard panels. These include Superpower, Blueprint, Mito Health and others.

If you have abnormal results or are actively working to optimize this biomarker, more frequent testing (quarterly) may be beneficial. Always consult with your healthcare provider for personalized testing frequency recommendations.

The standard laboratory reference range for Carbon Dioxide (CO2) is 23-29 mEq/L. However, many functional medicine practitioners recommend tighter "optimal" ranges for peak health and performance. Your ideal range may vary based on your age, sex, health goals, and other individual factors. Work with a healthcare provider familiar with optimal ranges to determine your target levels.
