You probably know that you need Vitamin A. You have also heard that it is possible to get a lot of Vitamin A. However, the terminology describing the amounts of the important nutrient changes considerably. Yes, the amount might be described as RDA, RAE, IU, as well as mcgs. How on earth is the average person going to know if you’re getting what you want if you’re told the RDA is 1 amount, but your multi-vitamin supplement lists the amount as an IU?
So, before we get into just how much vitamin A we want and how much could be too much, let us clarify the interpretation of this language that’s used. The RDA is the Recommended Dietary Allowances. RAE means Retinol Activity Equivalent and IU is International Unit. These also may be described in micrograms (mcgs) or milligrams (mgs). One milligram is equivalent to 1000 micrograms. The current RDA for Vitamin A is about 900 micrograms or 3000 International Units.
According to the National Institutes of Health, the top intake safe level is 3000 RAE or 10,000 IU for adults. Beside me I am looking at a few different bottles of multi-vitamin/mineral supplements. One bottle has 3500 IU per serving while another bottle has 5000 IU. Thus, it seems to me that someone wouldn’t very easily get an excessive amount of Vitamin A from supplements.
Did you know?
Vitamin A is a vital fat-soluble vitamin with some very important advantages. It’s essential for eye health, night vision, healthy skin and hair, mucous membranes, the immune system and for bone health. Food sources of Vitamin A can be extremely good. A sweet potato may have 28,000 IU, 1 half cup of spinach, 11,000 plus one half cup of carrots, 9000. Other really good sources include: cantaloupes, red peppers, black-eyed peas, apricots, broccoli, and tomato juice.
While in supplement form, it can be possible to get a lot of Vitamin A, generally you won’t receive too much from foods that are fermented. If you have consumed plenty of supplements and think you may have some toxicity from too much of the terrific nutrient on your system, here is some possible side effects: nausea, headache, fatigue, loss of appetite, or dry, itchy cracking skin.
