Question 1

how long does it take for a vitamin to work?

Accepted Answer

Vitamins: This is very difficult to answer because you do not specify what vitamin and what you need the vitamin to do for you.  If you have a true vitamin deficiency, it should be corrected within a month or even sooner with daily dosing.

Question 2

how long does it take for vitamin a to leave the body?

Accepted Answer

Many months: There is widespread agreement that it takes many months for vit a to leave the body but little specific info on how long. One website says the half-life is 6 months, meaning it takes 6 mos. For half of it to leave your body, but it does not cite a reference, and i could not find detailed info elsewhere, so the exact answer is a bit of a mystery.

Question 3

how long does it take for vitamin a overdose to clear acne?

Accepted Answer

What are you doing?: This is very dangerous. You can damage your brain trying this. If you have acne, and topical benzoyl peroxide hasn't cleared you in two weeks, your physician can help you find the right prescription medicine -- perhaps isotretinoin, a vitamin-a analogue. But the pop treatment of toxic vitamin a doses is dangerous and probably won't work as well as some simple stuff from your doctor.

Question 4

is vitamin a 10,000 too much to take daily ?

Accepted Answer

It is equivalent to: 1/2 a cantaloupe. It's a fat soluble vitamin, so if no fats are being taken along side it, it isn't absorbed very well. You are safe.

Question 5

is 4000iu of vitamin a too much to take daily?

Accepted Answer

Probably fine: Epidemiology generates all kinds of junk data and I'd ignore studies that report, "Thus-and-so many people with more than thus-and-so daily had more / thus of thus-and-so" unless it makes physiologic sense. This is more than you need to be healthy. Ten thousand is an often-cited recommended upper limit. Much higher vitamin A intake actually will make you sick.

Question 6

is it possible to take too much vitamin a from your diet?

Accepted Answer

Vitamin A Toxicity: Vitamin A toxicity is very unlikely from an average diet. It is a fat-soluble vitamin and can become toxic in the body if taking too much as a supplement.

Question 7

is zinc needs to be take with vitamin a?

Accepted Answer

No: Zinc and vitamin A are often taken at the same time as they both seem to have some beneficial effects on the skin.  But I could find no evidence that they need to be taken together. Good wishes!

Question 8

is it ok to take vitamin a after accutane?

Accepted Answer

Yes: As long as you take the usual one per day of vitamin, there should be no issue.

Question 9

how safe is it to take a vitamin a supplement?

Accepted Answer

Vitamin A: Vitamin a supplements are usually safe. Excessive vitamin a theoretically can affect/hurt your liver. Patients with retinitis pigmentosa take mega-doses of vit a often without side effect. The best way to get your vitamins is through a natural, green leafy veggie diet.

Question 10

how much vitamin a should you take if pregnant?

Accepted Answer

Vit. A & pregnancy: Dose is  5, 000 international units daily.
