Why normal lab ranges might not mean optimal health (and what you can do about it)! Here’s something fascinating about lab reference ranges: They’re based on population averages, not optimal health markers. This means you can be “within range” but far from your best. Consider these examples: • Vitamin D at 32 ng/mL is technically normal, but research suggests 60 for optimal immune function • Ferritin at 15 is in range, yet many feel best above 50 • TSH at 4.5 passes standard screening, though ma

Here’s the truth about normal lab values: they’re defined by what fits 95% of the population tested—not what’s ideal for your health. Imagine a bell curve: the middle 95% is “normal,” while the top and bottom 2.5% are “abnormal.” This range is statistical, not personalized. So, even if your labs fall within “normal,” you can still feel terrible—and often do, especially women in their 40s and 50s. For example, a woman with an HbA1c of 5.5% is told it’s “normal” by most traditional doctors, yet th

When someone tells us their traditional labs came back “normal”, we usually ask a different question, what does normal actually mean for your body? Most standard lab ranges are based on the average of the population, not the optimal function of a healthy system. They catch major problems, but they rarely explain why you feel exhausted, inflamed, foggy, or out of sync. At R3, we look deeper. Biomarkers that measure resilience, recovery, inflammation patterns, nutrient absorption, hormone balance,
