Most deficiency graphics give you a single number and call it science.
That’s not how repletion works.
Iron can raise hemoglobin in weeks and still leave ferritin empty at month 3.
Vitamin D responds to dose, not “get more sun” in a Canadian winter.
B12 and magnesium look “normal” on serum long before tissue stores catch up.
Calcium isn’t a 90-day supplement project it’s usually vitamin D, absorption, or parathyroid signaling.
We’re also not biochemically identical. Genetics, gut function, inflammation, hormones, medications, body stores, and whether you’re still losing the nutrient all change the timeline. That’s why one number on a graphic is almost never your number.
The useful question isn’t “how long.”
It’s: what’s low, why it’s low, can you absorb it, and are you still losing it.
That’s the difference between a pretty list and an actual protocol.
