Well Yve, I was surprised I saw Heather this time, she said double up the multi vit. They had helpfully lost my blood results from the previous time so I suspect that is what she is telling everyone. I didn't know that you were supposed to spread the calcium tabs either, apparently the gut can only absorb one at a time so taking two together doesn't give you two doses. I have been told to take one in the morning and one at night with those. Its baffling how different the advice is from within a single hospital!!!
