Re: Question on Vitamin D

[Guest guest]

Hi Victor,

You say to get vitamin D levels up around 100. Mine are currently at 93, and I

was concerned about toxicity, which according to some sources is at 100. Please

let me know your input on this.

Thanks

....While you do have vit D listed, make sure the levels are checked using the

same procedure as Lab Corp and get the levels up to near 100 using vit D3. Some

folks need as much as 20,000 units per day. Testing is the only way to know for

sure....

Like most medication, cholecalciferol is certainly toxic in excess, and, like

Coumadin, is used as a rodent poison for this purpose. Animal data indicates

signs of toxicity can occur with ingestion of 0.5 mg/kg (20,000 IU/kg ), while

the oral LD50 (the dose it takes to kill half the animals) for cholecalciferol

in dogs is about 88 mg/kg, or 3,520,000 IU/kg. An Overview of Cholecalciferol

Toxicosis. The American Board of Veterinary Toxicology (ABVT). This would be

equivalent to a 110-pound adult taking 176,000,000 IU or 440,000 of the 400

unit

cholecalciferol capsules.
