That says it's 100,000 IU per gram, so it's got fillers. 50,000 IU would be 1/2 gram, so with a small scale you should be able to weigh out 0.1 g, or 10,000 IU.
I messaged the seller they said it's just pure powder.

Vitamin D: 1 IU is the biological equivalent of 0.025 mcg cholecalciferol or ergocalciferol

If 1000 IU = 25 mcg, then 100,000 IU = 2500 mcg or 2.5 mg, not 1000 mg (1 g) as that link says. That means there are 997,5 mg of filler, or pure powder as the seller says, per gram.

Perhaps the seller made a mistake in the description I've looked at all the other products from them and no other products seem to have fillers.
