Summary

Both deficiencies have now cleared: vitamin D is 79 (in range for the first time in this history) and ferritin is 35 (above the 30 cutoff). The January recommendation's one warning — don't stop early — still applies to iron: 35 is over the line, not comfortably past it. Lipids drifted up a touch but remain in range; LDL is worth a glance next time.

What changed since last time

Vitamin D: 58 → 79 nmol/L — in range. The 41 → 58 → 79 arc is a textbook supplementation response.
Ferritin: 24 → 35 µg/L — replete, barely. Stores are thin; keep dietary iron up.
B12: 245 → 301 — solidly normal now.
Hemoglobin: 124 → 129 — best on record.
LDL: 2.8 → 3.1 and total cholesterol: 4.8 → 5.0 — still in range, both drifting gently upward across three reports.
HbA1c: 5.4 → 5.5% — normal band, unchanged in practice.

Wins

Both 2024 deficiencies resolved — vitamin D and iron each recovered on schedule.
Hemoglobin and B12 at their best recorded values.

Watch areas

Ferritin 35 — just above the cutoff; recheck next draw rather than assume it's durable.
LDL trend (2.5 → 2.8 → 3.1) — in range, but three rises in a row; worth confirming it plateaus.

Suggested actions

Drop to a maintenance vitamin D dose (winter especially) rather than stopping.
Keep iron-rich foods regular; retest ferritin at the next draw.
Nothing needed on lipids beyond the usual — recheck in ~12 months and watch the LDL line.
