Vitamin A, How much is really too much? ? ?

Monday, June 01, 2009

I asked about this on the Nutrition message board. This is what I posted:
I eat a lot of low calorie veggies and at times fresh fruit. I don't think I eat excessive amounts of any thing.

Many times, my NUTRITION FEEDBACK will say I am eating too much Vitamin A. It is often on the day that I eat the equivalent of one egg yolk that this happens.

I have also read the REFERENCE GUIDE for VITAMINS.
It mentions that fish oil among other things are also high in Vitamin A. Twice in the past few days, my Vit. A intake has been 520 to 1601. I read where it can be up to 3,000 mcg.

My concern is that at the direction of my doctor, I take Fish Oil capsules. I also take an Eye Health Vitamin minearal that contains Vitamin A. Should I be concerned?

I was exploring the Nutrition Tracker some more. When I looked at the screen where I can change the range it said women can have up to 800 mcg/day. So I changed my recommended range. I still go over that on some days.


Becky Hand responded & suggested this link.

On further analysis:
The nutrition tracker goal as set up is:
Consume between 100 & 800 %RDA of Vitamin A, IU
Therefore, the tracker is talking about IU's and not mcg.

From Becky['s article:
The recommended intake of vitamin A for adult females is 700 mcg RAE (2,330 IU)
Therefore, I am in range. I don't know why my original tracker range was 100-110.
I changed it to 800. I can actually up it some more.

Also, Becky's article is worth a read if you have a pregnant family member.
