I started taking a multivitamin as insurance and then found out that two of the things I was actually short of were the two it barely contains.
The bit I cannot resolve on my own is which deficiencies actually show up when intake drops this far, and which are worth testing rather than supplementing blind.
If the honest answer is that nobody knows, that is a useful answer and I would rather have it.

Iron studies on micronutrients — important especially for women:
| Marker | Baseline | Month 6 | After Supplementation |
|---|---|---|---|
| Ferritin | 56 | 24 | 51 |
| Iron | 86 | 56 | 84 |
| TIBC | 316 | 386 | 336 |
| Transferrin Sat | 34% | 16% | 25% |
My ferritin cratered at month 6 from reduced dietary intake. Iron bisglycinate 36mg with vitamin C brought it back up. Don't wait for anemia symptoms — test proactively.

Vitamin D levels and micronutrients: an often-overlooked connection. Obese individuals store vitamin D in adipose tissue, making it less bioavailable. As you lose fat, vitamin D can actually increase WITHOUT supplementation.
My trajectory: Baseline 18 ng/mL → Month 6 (with supplement) 42 ng/mL → Month 12 48 ng/mL. Target is 40-60 ng/mL. Adequate vitamin D supports immune function, bone health, and mood — all relevant during weight loss.

Same experience, arrived at from the opposite direction. I had assumed I was the exception until I read this.
Adding the clinical framing, because it changes how the question reads.
Blood count monitoring for micronutrients: my doctor noticed my MCV (mean corpuscular volume) trending up at month 6: 91 → 97 fL. This flagged potential B12 or folate deficiency.
Sure enough, B12 had dropped from 620 to 340 pg/mL. Started B12 injections monthly and MCV normalized within 2 months. GLP-1 agonists can impair B12 absorption — this is a real clinical concern that deserves routine monitoring.
