Other natural carotenes
can provide challenges due to their variability, stability, and storage and handling requirements.
Some of these carotenes were not found in all samples, which is usual, as long as the analyzed samples proceeded from different places.
capitata carotenoids, without reduction of carotene content.
Objective: To study the protective role of beta carotene against acetaminophen-induced hepatotoxicity in rats.
Control group C was given NIH laboratory diet, experimental group A was given toxic dose of acetaminophen 700 mg/kg body weight once daily and experimental group B was given beta carotene 30 mg/kg body weight once daily along with 700 mg/kg body weight acetaminophen once daily for one week.
Dozens of familiar, brightly colored, yellow, orange or dark-green vegetables and fruits provide carotenes.
Research may also help produce customized dietary guidelines that take into account an individual's ability to convert carotenes from fruits and vegetables into vitamin A.

Ideally," adds Burri, "it may also help us produce customized dietary guidelines that take into account an individual's ability to convert carotenes from fruits and vegetables into vitamin A.
Department of Agriculture researcher Philipp Simon boosted the carotene levels of carrots over the past several years using a natural-plant breeding program at the University of Wisconsin in Madison.
His work and that of others already has pumped up beta carotene - a substance associated with cancer prevention - in commercial carrots by about 60 percent, from 90 parts per million to 150 ppm.
This formula also contains neurological support through high doses of antioxidants including C, E, carotenes
glutathione, N-Acetylcysteine and neurotransmitters phosphatidylcholine, L-tryosine and DL-phenytalanine in a amino acid complex, plus B complex vitamins.
Right now, carotenes
aren't among the list of 23 vitamins and minerals that are known to be essential," says Betty J.
People who eat more fruits and vegetables, especially those rich in carotenes
