Instead of 400 IU an infant was given 12,000 IU of vitamin D daily for 20 days
Due to parents giving 1 mil liter as they were used to instead of 1 drop, from the new product
Authors were extremely concerned about infant toxicity
However, no problems at all:
Small excerpt from the paper

20 days at 12,000 IU per day = 240,000 IU
Blood level was 400 ng/ml, which dropped down naturally to 50ng in 4 months

There continues to be is so much fear from vitamin D toxicity – even with decades of experience around the world with very young humans and other mammals with very high levels of vitamin D
