if he does take supplements though
>>31768 i think [link-ommited] units of vitamin D taken together with 100 mg of vitamin K (iirc that was the standard amount in 1 capsule, maybe it was 100 mcg i don't remember) daily should be optimal for recovering levels
i've been taking supplements for some time and that's how i did it, apparently vitamin K is important for some sort of processing of vitamin D and the health issues resulting from taking vitamin D is mostly because of not taking vitamin K with it
also i'm sure there's some food rich with vitamin D, internet says dairy
