| Only just been advised by a friend from Vermont to take 5000iu- which seems massive. Just got some and the recommended dose is 400- so happy to increase to 800- but 5000??? Risk of kidney stones, etc. Never taken any before. | |

This is what the Swiss govt recommends apparently. I understand in total, not supplementary. The risk of OD seems small.
