I will be the first to admit that I treated vitamin D with great temerity and disregard because it is a hormone and not a vitamin. But I have to disagree with Mercola et al on this.

 

For many years, millions were saved from death and miserable lives by dissemination of vitamin A in single doses of up to 2 million IUs, The people receiving these doses could not be vitamin D deficient because they were not all dark-skinned and had an abundance of sun exposure. Are we to forget the 70 years experience and successful human trials of pure vitamin a in favor of the recent knee-jerk hysteria regarding vitamin D?.

 

I have gotten around this problem by giving a four to ten day megadose of vitamin A totalling 500,000 IU of vitamin A, followed by 2000 to 5000 IU per day ov vitamin D. This megadose cycle should be repeated every six months.

 

Much of the fear surrounding vitamin A seems to have been perpetrated by doctors who do not understand the difference between synthetic beta-carotene and preformed vitamin A from fish liver oils. Peace Corps veterans have noted that even if a negative effect from vitamin A were noted the effects were totally reversed within 72 hours. Plus it has been determined that it takes 250,000 IU of vitamin A for nine months for a negative effect to appear in a person who does not immediately exhibit allergy or sensitivity to vitamin A. However, tests of high dose synthetic beta-carotene supplementation have been shown to promote infection and increase the growth rate of certain pre-existing cancers.--- On Tue, 3/16/10, tjsthunder <tjsthunder wrote:

Thanks Tony for your thoughts. Mercola's article sounded a bit unbelievable so I

am glad that you made a distinction between beta carotene and fish liver oil.

that even if a negative effect from vitamin A were noted the effects were

totally reversed within 72 hours.  Plus it has been determined that it takes

250,000 IU of vitamin A for nine months for a negative effect to appear in a

person who does not immediately exhibit allergy or sensitivity to vitamin A. 

However, tests of high dose synthetic beta-carotene supplementation have been

shown to promote infection and increase the growth rate of certain pre-existing

cancers.
