High MCV or MCH on your labs is one of the biggest clues that your red blood cells aren’t forming correctly — and it’s often missed.
To build healthy RBCs, your body needs:
• Iron, folate & B6 for hemoglobin
• Copper & zinc to move iron into the cell
• Magnesium & riboflavin for ATP + bone marrow energy
• Vitamin A to release stored iron so it can be used
When these nutrients are missing, red blood cells become large, immature, and poor at carrying oxygen — which is exactly what high MCV/MCH reflect.
What suppresses bone marrow?
• Excessive alcohol use or binge drinking
• Chronic viral infections
• Long-term inflammation + toxins
What disrupts RBC formation today?
• Simple nutrient deficiencies
• Glyphosate interfering with glycine (a building block of heme)
If you’re tired, foggy, or short of breath, this pattern is not just aging.
It’s a biochemical signal that deserves a deeper look.
