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 safe to take anti oxidant pills containing beta carotene, selenium and zinc for more than one month?

Is it safe to take anti oxidant pills containing beta carotene, selenium and zinc for more than one month?

Extremely safe: Selenium and Zinc are essential nutrients with many proven health benefits. We need to either take them as supplements or get them from diet to be healthy. Many people don't get adequate amounts in their diets. Beta carotene is a precursor of Vitamin A, another essential nutrient, and is also safe to supplement, but I feel that a mixed carotenoid complex has more benefits than beta carotene alone. ...Read more

If you have an excess of vitamin a stored in your liver, what happens when you eat beta carotene?

Probably very little: An excess of beta carotene gives you a bright yellow skin called carotenemia, often mistaken for jaundice. It is entirely benign and disappears if yellow vegetables are cut back. This probably means that there is a natural mechanism that stops the oxidation of beta carotene to make vit a if it is not needed. ...Read more

What are vitamin a rich foods that needed to be avoided during pregnancy?  I know beta carotene format is the best
