I was taking 50,000 a week, and it took 6 weeks and my levels were up to 55 from 30, so I am taking it every 2 weeks, and will check again in a few months.

I also have found that since I added 600mg of magnesium I no longer get cramps in my hips or legs or toes.. and I sleep like a lamb
I take Calcium also, 450 one in my multi and a single 250 at bedtime.


I take the 50,000 in the am,,,seems to be fine for me...
