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 moreSee 1 more doctor answer
Is there anyway to rid the body of excessive carotene/vit a quickly? Like laxatives? Vit a from veg=3500% rdi most days. My skin is reallllly orange
It will fade: Taking a large dose of vitamin a itself is very dangerous but it's common and harmless to turn orange if you really like carrots. Some folks take carotene tablets to acquire the color; if you overdid it, you'll do best simply to let it face which it will do in a few weeks. Laxatives will just make you sick. ...Read more
Safe: Beta-carotene is a precursor to vitamin a and is found in many foods. Skin care products contain small amounts of vitamin a- very little will be absorbed.

Is beta carotene an effective anti aging skin care ingredient since it also converts to vitamin a? Is it safe for nursing moms?
Not in pill form: Beta-carotene can be found in carrots, sweet potatoes, etc. It is wise to include such vegetables in your diet. However, don't take beta-carotene in pill form as a major study showed it could be harmful. As a cream, it is helpful for the skin in certain forms. Discuss with a dermatologist the best product for you. The best anti-aging for skin is protection from sun damage. ...Read more
I've been told great things about taking juice plus for skin irritation and hair loss. But also read that it has too much
beta-carotene in it. HELP!?
Try it: Hair loss at your age is hypothyroidism until proved otherwise because you will become bad-sick if it is missed. Your physician needs to be in the loop. These "natural healing" people make unsubstantiated claims and trash one another's products with little or no science. Try it, you should be safe, do not expect any miracles; consider getting with an evidence-based holist for good guidance. ...Read moreSee 1 more doctor answer

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 moreSee 1 more doctor answer
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
