There is no problem with taking a large amount of vitamin D. Concomitant use of vitamin k is necessary. I have ingested 50,000 to 100,000 IU. Periarthritis of the shoulder took 5 months last time, but this time it almost improved in about 2 months. Awakening in the morning is refreshing. It is full of vitality at night.
