I’m 46. I’ve been on 10,000 IU daily for over a year, and I’m planning to cut to 5,000 and recheck in 3 months. On 9/18/2026 my PTH was 8 and flagged low. Vitamin D was 87.8, up from 36.7 in May and 76.9 in August. Calcium wasn’t drawn that day. The last ones were normal, 9.4 in December and 9.2 in January, with albumin 4.5–4.6. Kidneys are fine, creatinine 1.06. No phosphorus or magnesium on the labs, and I don’t have cramps or tingling. Besides vitamin D, PTH, calcium, and phosphorus, is there anything else worth adding to that 3-month recheck?
