Very good morning doctors. for low vitamin d on bloodwork (22) is it safer to ingest over-the-counter vitamin d3 because it is animal based than to ingest prescription vitamin d2 or over-he-counter vitamin d2 because it is plant based?

It is up to your belief. Vitamin D2 will be converted to D3 so taking D3 is directly affecting the level but you can take either type. The really active vitamin D is active vitamin D3 but this fact is only important for people with advanced chronic kidney disease (stage 4-5 chronic kidney disease).

Vitamin D-3 is thrice as potent as D-2, and is the most appropriate for human consumption. Your level is low, and, in my opinion, you should try to get blood level of OH-Vit-D-3 to between 50-70 ng/ml. You can enhance your situation via oral intake or increased sunshine without sun-blocker. Check levels in about 3 months.
