Too much Vitamin A?

[Guest guest]

I surprised to read this in Mercola today (my girls are getting about 7,000 IU

of A a day lately):

The British Medical Journal has published a remarkable paper confirming that low

vitamin D levels obtained in the past are a risk factor for developing colon

cancer in the future.

But the study contained an even more significant finding -- as Dr. Cannell's

site has reported before, vitamin A, even in relatively low amounts, can thwart

vitamin D's association with reduced rates of colon cancer.

This is the largest study to date showing vitamin A blocks vitamin D's effect.

Hidden on page eight of the paper was one sentence and a small table, showing

that the benefits of vitamin D are almost entirely negated in those with the

highest vitamin A (retinol) intake.

And the retinol intake did not have to be that high -- only about 3,000 IU/day.

Young autistic children often take 3,500 IU of retinol a day in their powdered

multivitamins, which doesn't count any additional vitamin A given in high single

doses.

Here is a link to an article in which the Weston A. Price Foundation discusses

the synergistic effect of vitamins A & D. Natural CLO doesn't seem to cause the

problems caused by the highly refined/processed versions:
