Accutane or a lot of Vitamin A

Accutane is a naturally occurring derivative of vitamin A and is detectable in the bloodstream of all people. Vitamin A in large doses has the same effects as Accutane, both good and bad, but quickly becomes harmful since it builds up in the tissue. (Important: Don't take any vitamin A while on Accutane). Accutane is formed naturally in the body from the Vitamin A present in the bloodstream. This is why large amounts of Vitamin A taken during pregnancy cause the same birth defects that Accutane does. Fortunately, because it is a naturally occurring product, the body is able to quickly remove Accutane from the bloodstream. It is gone from the blood within nine days and has no lasting effect on future pregnancies
Does this mean, that taking a lot of vitamin A will have the same effect as taking say 40mg of accutane? I dont get this info. Someone, any clue? I'm on 40mg right now and taking multi vitamins.

If You Get Too Much

Excessive vitamin A can cause serious health problems. It's virtually impossible to get too much of this nutrient from foods; the body makes only what it needs from carotenoid-rich fruits and vegetables. But care is needed when taking supplements containing "preformed" vitamin A, meaning it has been synthesized for you already during the manufacturing process.

Symptoms of vitamin A toxicity include dry and cracking skin, brittle nails, excessive hair loss, bleeding gums, weight loss, irritability, nausea, and fatigue. An extremely high single dose--500,000 IU, for example--can cause vomiting and weakness.

General Dosage Information

Special tips:
--Some sources measure vitamin A in retinol equivalents (RE) rather than international units (IU); one RE is equivalent to 3.3 IU.

--Most multivitamins offer vitamin A as beta-carotene, an antioxidant that the body can convert to vitamin A. However, the amount of vitamin A produced during this conversion is small and inadequate for those conditions in which vitamin A itself was shown to be therapeutic.


For improved resistance to colds, flu, and other viral infections: Take 50,000 IU twice a day for five days; then reduce to 25,000 IU a day, if necessary, for no more than 10 days.
Cautions


Don't exceed recommended doses of vitamin A. Large doses of preformed vitamin A can build up to toxic levels.

If you're pregnant or trying to get pregnant, don't take more than 5,000 IU of vitamin A daily. Higher amounts may result in birth defects. Practice birth control if consuming doses greater than 5,000 IU, and for a month after stopping.
