For instance, in one case a person taking 8,000 of vitamin D for several years found his level very high after consistently running a blood level of eighties to ninety. I think what happens is the fat tissue gets filled after a long period, then the vitamin D has no other place to go except the blood. Although toxicity is at over 200 ng I see no good reason to go above 100 ng, except perhaps in a very threatening illness. This particular person found that 2,000 iu would do what 8,000 was doing before.
Any one who tells you how much to take is the right dose to do indefinitely, does not understand how this works. The only way to monitor is by a blood test. To low a number means you are not getting the benefits you would get with a higher number. By the same token to high a test number would be unknown and that person would not know to take corrective action. The proper dose starting out is 1,000 iu per 25lbs body weight and this with a caveat. Test in three months and see where you are. Then adjust accordingly.
On www.grassrootshealth.net there is a table of what to expect if you have a certain blood level and how much it takes to obtain a better reading. It is not a linear relationship. For instance: If you blood level is 20ng and extra 1000 iu a day will increase your blood level ten ng to 30 ng. If your blood level is 88 ng and extra thousand will increase it to only 90 ng. Not a linear relationship and it depends on your starting level. So test!
So today's News Letter.
