You have heard it before. "Your labs are normal." You walk out feeling like you should be fine, but you are not fine. You are tired. You are foggy. You are not recovering the way you used to.
Here is the problem. "Normal" on a lab report does not mean optimal. It means your result falls within a statistical range that includes a lot of people who are not thriving either.
How Lab Ranges Are Built
Most lab reference ranges are based on the population average. They include everyone who gets tested, which increasingly means people who are overweight, stressed, inflamed, and running on empty. So when your results come back "within normal limits," you are being compared to a population that is not exactly a picture of health.
A Mayo Clinic Proceedings review explained that a wide "optimal" range for vitamin D is reported as 25 to 80 ng/mL, and differences of opinion exist as to the definitions of insufficiency and deficiency. The authors noted that optimal levels might depend on the health outcome in question, with cancer prevention requiring higher levels than bone maintenance. Read the study here.
What "Optimal" Actually Means
Optimal is different. Optimal is the level at which your body functions at its best, not just the level at which it avoids a diagnosis. Here are a few examples:
- Vitamin D: Lab "normal" starts at 30 ng/mL. Optimal for immune function and bone health is 40 to 60 ng/mL.
- Ferritin: Lab "normal" can start as low as 10 ng/mL. But a randomized controlled trial showed that women with ferritin below 50 ng/mL experienced significant fatigue, and those below 15 ng/mL saw dramatic improvement with iron treatment. Read the study here.
- Fasting insulin: Lab "normal" can go up to 25 mIU/L. Optimal is under 8 mIU/L. Anything higher suggests insulin resistance is already developing.
The Vitalized Approach
At Wellness Vitalized, we do not read your labs as pass or fail. We read them for optimal. We look at patterns, not just individual numbers. We connect what your labs say with how you actually feel.
This is the difference between being told "you are fine" and actually feeling fine.
