50,000 IU does sound high but it is normal to take high potency amounts of a vitamin especially if you are deficient. IтАЩm low of my vit B12 and my doctor advised me to take 1000 mcg daily, which is 41,000% the daily dosage, to help replenish it. Vit B12 and D can be stored in the body for later use as well.
You mention 50,000 IU of Vitamin D. Is that daily? If it is, this is 10x all previously suggested amounts. It sounds unreasonable.
50 000 IU is a lot, but they studied different dosages and found that the higher the dosage, the lower the risk for infection.
But even lower dosages give a good effect too, much better than nothing at all.

D3 stays in the body for an extended period, but D2 does not.
D3 and K2 should be taken together.
