Can 122, 000 iu of vitamin a/day x 60 days from veggie juice cause toxicity despite being a carotene? What if combined w/1000 iu from fish oil supplem.

Vitamin A toxicity: Vitamin a is a fat soluble vitamin and can cause toxicity. These effects can be extensive, and can affect the liver severely. It can cause hair loss, and marked dryness on the skin, lips and other mucosal surfaces, among many other changes in the bone, the central nervous system, and other parts of the body. ...Read more

Can anybody overdose on b-carotenes from eating veggies or that isn't possible?

Can anybody overdose on b-carotenes from eating veggies or that isn't possible?

Veggies Are Good: Eating foods rich in beta carotene such as carrots, green leafy vegetables, spinach, pumpkins, and sweet potatoes will not harm you. However the danger of overdose occurs with overuse of beta carotene supplements. The most prominent symptom of overdose is a yellowish skin discoloration of the face, palms of the hands and soles of the feet. Check with your doctor before adding these supplements. ...Read more

I'm taking prenatal vitamins as i'm ttc. They have 4, 000 iu vitamin a as beta-carotene. I eat lots leafy greens such as kale. Is that dangerous?

Not at all : Taking 10, 000 iu of pre-formed vit a during pregnancy is hazardous; docs generally advise limiting a to 4-8000 iu to be safe, but your prenatal contains no vitamin a; beta carotene is not vit a but a precursor your body can convert to a as needed. Beta carotene is not hazardous. See http://www.Care2.Com/greenliving/is-vitamin-a-safe-for-pregnant-women.Html ; http://teratology.Org/pubs/vitamina.Htm. ...Read more

See your doctor: The most likely explanation is usually the beta carotene one- kids eat more yellow fruits and vegetables than other types. Jaundice can appear with yellowing of the skin, but will also affect the sclera of the eyes (the white part). See your doctor to figure out what is causing this in your child. ...Read more

Is it ok to use rose hip oil and vitamin E oil during pregnancy? I heard rose hip oil is high vitamin a. Is this beta carotene based?

Yes: No more than 10, 000 iu of preformed vitamin a should be taken during pregnancy but preformed vitamin a is only found in animal foods (meat, eggs, dairy). There are no vegetarian sources of actual vitamin a- any "vitamin a" said to be in those foods are from carotenes and those are very safe in pregnancy.

Is it true vitamin A & E suppl. increase the risk of cancer! I read on internet smokers used beta-carotene were 18% more likely to get lung cancer!

Possibly: It is true that these supplements do not help to prevent cancer and may increase risk of some cancers. Your doctor may still feel you need them for certain problems, but you should not take them as a cancer preventative. ...Read more

Does beta carotene fight cancer?

Maybe: Please forgive this senior physician's frankness. The data on carotenes and lycopenes is so massive, so contradictory, is so tied up with the politics of "healthy diet", and makes so little sense scientifically that your question cannot be answered. In science, the stuff that's really true is generally established quickly. I love eating carrots, but would not spend money supplementing carotene. ...Read more

Are beta-carotene supplement dangerous ?

Possibly in smokers: Some studies have found high doses of beta carotene in smokers increases lung cancer risk, yet other studies have found it doesn't increase risk. Antioxidants work as a team & the studies showing increased risk gave beta carotene without other antioxidants to balance it. See http://tinyurl.com/p34vo4b It's wiser to take mixed carotenoids & get through diet. If you smoke use caution-better to quit! ...Read more

What to do if I am on my last month of isotretinoin (acutane) and I want to start to take beta carotene, can I take them when I'm on acutane?

I wouldn't: There's no health benefits to beta carotene in this situation. Both are of course related to vitamin A and there are a few unknowns. Congratulations on completing your course of isotretinoin -- it's not for the faint-hearted and chances are it's been of huge benefit to you. Best wishes. ...Read more

How much more beta carotene would I get in pulped carrots compared to a shop bought bottle of carrot juice?

Not more: As best as I can tell, carrot juice may have more nutrients than the pulp, but both the juice and the pulp contain high levels of beta carotene and other nutrients. See http://healthyeating.sfgate.com/better-drink-carrot-juice-eat-whole-carrots-7430.html ...Read more

If 100grm of squash has 100% RDI of carotene, how much roughly could be eaten daily without skin yellowing? Would mineral oil stop absorption much?

If 100grm of squash has 100% RDI of carotene, how much roughly could be eaten daily without skin yellowing? Would mineral oil stop absorption much?

All you want.: 1st, there is no official RDI for carotene; everybody has a different number. 2nd, I've never seen carotenosis from squash (and my daughter, a vegetarian, eats a TON of it). 3rd, carotenosis due to eating vegetables is harmless, so if you somehow eat enough squash to yellow your skin, cutting back will reverse it. So eat what you want. Mineral oil would have no significant effect on absorption. ...Read more
