Six months of whole foods, cooking at home, eating vegetables. Bloodwork came back: Vitamin D deficient, magnesium low-normal, B12 borderline.

The issue wasn't my diet. The issue was I had no idea what I was actually getting day to day. I assumed. Everyone assumes.

The problem with micronutrients is there's no feedback loop. You feel fine until you don't, and by then you've been running a deficit for months. Macros you can feel. Micros are invisible.

I downloaded Vitamin - an iOS app that logs your food and supplements and shows your daily totals for each micronutrient. Not a meal planner, not a calorie counter. Just: here's what you got today, here's your target, here's the gap.

First week I could see I was consistently short on D and magnesium on days I skipped my morning routine. That's it. That's the whole insight. But it's the insight I needed to actually fix it instead of guessing.

Three months later my D is in range. Magnesium is solid. I didn't change my diet dramatically - I just got consistent where I was inconsistent because I could finally see it.

If you've had bloodwork flag deficiencies and you're not tracking, you're fixing the symptom not the habit. [This helped me fix the habit.](https://martspec.com/vitamin)

How are you monitoring your micronutrient intake right now?

Bloodwork showed I was Vitamin D deficient despite "eating healthy" - started tracking micronutrients properly and here's what actually changed
