This article is part of a broader study by the National Telecommunications and Information Administration (NTIA) about the uses and limitations of self-regulation. The NTIA has also already given (somewhat qualified) support for a self-regulatory approach for the control of personal information in telecommunications.1.
Vitamin B6 Overdose. People taking large dosages of vitamin B6 (pyridoxine) on a regular basis for an extended period of time should be aware that problems can arise. There is a potential for damage to your nerves, but in most cases it is reversible.
Although very rare, it is possible to overdose and become toxic with supplementation as vitamin D is a fat soluble vitamin and therefore stored in the body for longer periods of time. Therefore if you are taking 5,000 IU or more daily, you should have your blood levels monitored approximately every 3 months.
