Sbrace- THanks for your input I was going to try to find some of your old posts. How low was your vitamn D level and how long did it take to bring it up? Also regarding the 10000 units-I hear of people taking so much more & it not be toxic or is
that b/c you were taking it for a week straight. Regarding your boys-do you ever retest them? Do you know what there levels are?
I can't remember my level! I know it was well below 20 and before I was tested I had been aggressively supplementing so it had to be much lower prior (during pregnancy and breastfeeding). I upped to 10,000 IU per day and my level was good (above 50) the next time I was tested which was less than 2 months later. I wish I could find the slips to give exact numbers and time frames but it's been quite a while since that point.
I take large doses myself (say 40,000 yesterday) for various reasons. Toxicity of D happens with high dose over time. It's not a short term thing. So if you stay under the limits overall you're fine. For example, you could take 65,000 every Monday theoretically and still be under the 10,000 IU per day limit that I'm personally comfortable with). If a person is low that limit wouldn't apply. I just like it because it seems to be a number that, as long as a person stayed within, where there has never been an incidence of toxicity regardless the underlying levels. So it's a number you can give a person who doesn't know their level. My FIL was very low and had prostrate cancer. He started supplementing and when they tested I think he was in the 80's. My husband was very high too when he tested after supplementing high. So I don't think anyone needs that high of a level routinely unless they are correcting low levels. I don't think it hurts either.
My son was 55 and his brother 45 when we tested. We upped the 45 guy a bit and then just kept doing what we were doing. I had them tested when I knew I was low so it's been a while. I should probably do it again.
