In a vitamin, what does it tight-fisted if the bottle say "8000 I.U" ?
Answers: NO IT WOULD NOT BE SAFE TO TAKE TWO! IN FACT, IT COULD BECOME TOXIC.
IU stands for International Unit, which used to be the method of height for Vitamin A. It has since changed to ug (micrograms) of RAE, which stands for Retinol Activity Units. Converting from IU to ug of RAE vary depending on the form of Vitamin A your talking in the region of. For most supplements however, it averages that 1 IU = 0.15 ug of RAE.
So if you take 8000 x 0.15 = 1200 ug of RAE.
The recommended intake of Vitamin A for adults ages 19 - 30 is 700 ug of RAE per daylight.
Vitamin A is stored in the body - so the probability of you needing any vitamin A supplement is pretty slim. But contained by high doses it have shown to become toxic. It can damage your liver and produce birth defects if you become pregnant. The max counsel before toxicity starts to transpire is 3000 ug of RAE/day. In some people, this number can be smaller number.
Vitamin A just so happen to be a very complex vitamin, which is why it be measured in IU, and why it's measured contained by RAE's now. You won't find an IU or an RAE for any other nutrient.
Always try to appropriate one vitamin each year. "8000 I.U" its a amount of vitamin A. Take one each light of day.or ask your doctor first.
