Overage on Vitamin A

I am concerned about my intake of Vitamin A being over the 100% goal. How much overage can lead to health problems? I each a spinach salad each day for lunch which I love but with 2 cups of baby spinach I am at about 115% not including other items in the salad that have a few extra percents. I also drink a muscle milk each morning for breakfast which contains 20% of Vitamin A. This puts me even further over the goal and still counting with other foods that have smaller percentages. I really enjoy both the muscle milk and my spinach salad. Do I need to be concerned?

    There are different forms of vitamin A and only retinol from foods like liver is toxic in excess. The carotenes found in fruits and veggies are precursors and are non toxic.

    I think the general rule is that retinol is from animal products and carotenoid is from plant products. So if you're getting most of your vitamin A from plant products you should be okay and don't worry about overages too much. If you find your vitamin A is coming from animal products then you should cut back, as it can cause liver problems and decreased bone density.

    Hi group, my issue is I'm deficient in vitamin A I'm taking a 10,000 IU pill every morning plus what ever I get from food. Now the kicker is im a weight loss surgery patent and this is my only issue granted a big one! My issue I think is my low fat diet? Being that vitamin A is a fat soluble vitamin? Any thoughts would be helpful!

    Your odds of damage are probably pretty low. But if you are worried ask your doctor. He/she can better speak to this vitamin in relationship to your surgery.

    Comparative safety statistics

    In the United States, overdose exposure to all formulations of "vitamins" was reported by 62,562 individuals in 2004 (nearly 80%(~78%, n=48,989) of these exposures were in children under the age of 6), leading to 53 "major" life-threatening outcomes and 3 deaths(2 from Vitamins - D and E; 1 from polyvitaminic type formula, with iron and no fluoride).[2] This may be compared to the 19,250 people who died of unintentional poisoning of all kinds in the U.S. in the same year (2004).[3] In 2010, 71,000 exposures to various vitamins and multivitamin-mineral formulations were reported to poison control centers, which resulted in 15 major reactions but no deaths.[4]

    http://en.wikipedia.org/wiki/Hypervitaminosis_A
    The U.S. Institute of Medicine says that the Lowest Observed Adverse Effect Level (LOAEL) for vitamin A, when taken over an extended period of time is 21,600 IU.[7] Most multivitamins contain vitamin A doses below 10,000 IU, therefore multi-vitamins are unlikely to cause vitamin A toxicity when taken at their recommended dosages.
