Clinical Research & Evidence
Every testing category at Jaelion is grounded in published clinical literature and guidance from recognized health authorities.
Our Evidence Standard
Jaelion references peer-reviewed literature, federal health agency guidance (CDC, NCCIH, NIDDK, WHO, EPA), and professional society guidelines (AGA, ACG, AAAAI) to support each testing category.
We also publish our methodology and limitations openly. We believe that a credible testing partner should be transparent about what the evidence supports, what it does not support, and where clinical judgment must fill the gap.
Whole-Patient Rationale
The clinical and scientific basis for whole-person care and why it supports a more structured approach to dietary, nutrient, and exposure-related testing.
Intolerance Testing Evidence
Evidence supporting the clinical relevance of food and substance intolerance testing, dietary pattern effects on wellness, and structured intolerance assessment in integrative care settings.
Nutrient Status Evidence
Published data on micronutrient deficiency prevalence, absorption physiology, and the clinical implications of nutrient status in complex cases.
Toxicity & Biomonitoring Evidence
CDC, WHO, and EPA guidance on biomonitoring, environmental chemical exposure, and the appropriate interpretation of exposure data.
Methodology & Limitations
A transparent review of how Jaelion selects and positions testing categories, including known limitations and appropriate clinical framing.
