One point of caution:

Anyone who takes Vitamin D supplement, make sure you take 25-Hydroxy (Calcifediol) and not the active form - 1,25 dihydroxy (Calcitriol).

Active form has severe side effects and is not supposed to be used for supplementation unless in you have kidney problem which prevent metabolizing 25-Hydroxy.

I thought all D2 and D3 supplements would be ergocalciferol and cholecalciferol, respectively, while calcitriol is what gets tested to assess blood levels. Do any supplements actually contain calcitriol?

Medical system in India is a mess of kickbacks. A Doctor gave my cousin a prescription of Calcitriol because it was much more expensive. Led to major side effects which went away as soon as it was stopped.

Supplements don't have it. However that warning was for someone who goes out of way to acquire Calcitriol.
