HI everyone. I've been lurking steadily for a while, and popped in here and there throughout this pregnancy.

I'm wondering if anyone knows what a max safe dosage of calcium/magnesium would be daily?

Restless leg syndrome is driving me crazy at night, I totally can't sleep, can barely even lay there. I keep taking the cal/mag supplements, but I'm up to 16,000 mg of cal/ 6400mg of mag (that's 16 pills!) and they do kick it quickly so I can go to sleep, but I will wake up with a mild case of it before morning.

I know I used to take huge dosages like this in high school for cramps, and never seemed to suffer any problems from it, but just wondered if anyone had any dosage suggestions or cautions.

That sounds like a lot to me, but I am into mega dosing where safe! I don't know the specifics but I have read that certain forms are a)safer and b)more readily absorbed by the body and that might be more important than how much you are taking. For example, the kind of calcium in Tums is poorly absorbed and apparently can cause calcification in the placenta but I have only read that part once.
I have read vit C helps in absorbing them better, I always take my cal-mag with vit C but I think that upping my iron (or actually taking some at night, but earlier than my cal-mag because they can both interfere with eachother) also with C seems to be helping. My RLS is not very bad at all though I can feel it lurking and it was worse before I was constant with both the above (but I think I am only taking about 2000cal).

I don't have any leg cramping (which i attribute to yoga and stretching daily), but take calmag for my tremendous amount of BHs and have been reading up a lot on it. I learned most people are magnesium deficient, but not calcium and there needs to be a balance. I'm taking liquid form, my MW said forget about the tabs/capsuls, your body just doesn't absorb them well. I'm also planning on getting magnesium powder this week to balance my calcium intake (i'm a huge dairy fan). I haven't heard about the vit c thing, but have heard it should be w/citrus, so find a liquid w/it (it'll say citrate). i often mix orange flavored liquid cal/mag w/OJ.
Another thing that should really help you-take baths w/epsom salt! It is magnesium and sulfates and will absorb readily through your skin-sooo good for you!
In all my research i haven't heard what or if there's overdose limits, but not sure---i do think the RDA is too low, though, IMO

It is vitamin D which helps your body absorb calcium, not C, as far as I know.
