At least in the UK, it's pretty easy to get D3 over the counter too. I've been buying D3 drops off of Amazon.

Looks like I misunderstood it. Calcitriol is different from D3. Normally your body converts D3 to calcitriol but those with certain diseases will not get it converted.

Calcitriol is actually the most confusing of my medications to manage since the dosage needs to be adjusted based on monthly blood tests. Things like amount of sun exposure can swing my numbers around. And it interacts with so many blood test numbers like PTH, phosphorus and calcium levels.
