I know the subject vit.d.
100 is not max. Maybe in your country indicated as max. From 300 it is getting toxic. But you don’t get there.
I have been talking to docs who told me being above! 100 is very good. Only mainstream opinion is telling you vit.d is toxic.
So, your level is not good. If you don’t believe me, okay.
Calcium: if you higher dose just vit.d, you get your calcium. But check your ca/ Magnesium ratio.
Bzw, 6000 IU is nothing, you won’t have any significant effect. Go into the sun and you get 100 000 iu in two hours. Depending on your skin colour.
BTW I know the controversial studies but also self experience books and the opinions of docs who don’t say that in public.
If you believe your facts, perfect. Not sure, if you can expect or doing any progress by not changing your vit.d protocol.
Anyway, good luck.
