Thank you Marz, it's the former ng/L, I have been taking 4000 units daily with K2, and yes I do take magnesium. Do they help with absorption? Should I increase my dose to 6000 units?
Magnesium works with the D to aid absorption. K2-MK7 directs improved calcium uptake from foods into bones and teeth - rather than hanging around the arteries and soft tissues.
According to Grassroots Health - link in my last Reply - suggests 1000 iu's for every 10 points below 60. So your current dose should be adequate. If you can tolerate more then you could boost your dose during the winter months.
Thank you, this is really helpful. I have been taking 4000 units for the past year, so with results of 30 it would make sense to raise by 3000 units to go up to 60?
Your result of 30 requires at least 3000 to bring you up to 60 - so your current dose of 4000 should be fine. I suggested you could increase for winter if you tolerate D well - some don't ....
Ah I see, thanks for claryfing. I have Hashimotos, maybe I don't absorb it well, not sure. I tolerate it very well and will increase it a bit. Just something came to my mind...I have been taking Solgar vit D in tablets, instead of my usual brand in oil. I wonder if this could have skewed my results?
Thank you Carys21, just calculated it and it seems I need 10,000 units a day based on my weight and current dose to achieve 60. I will double my dose for now to 8,000 and see how I get on
