Since covid hit I wasn't really going outside that much. I was taking 2500 IU daily since September. Got tested in December and had 102 nmol/l. The conservative reference is > 75 nmol/l and newer ones are 100-150 (https://www.grassrootshealth.net/document/vitamin-d-dose-response-curve/ https://www.grassrootshealth.net/document/vitamin-d-dose-res...). So even with 4+ months of taking 2500 IU I was on the lower end of the reference.
