Research Papers that Mention the Interaction
“Some carotenoids contribute to vitamin A requirements.”
“Provitamin A carotenoids (β-carotene, α-carotene, and β-cryptoxanthin) contribute to the dietary intake of vitamin A and are associated with decreased risk of many chronic diseases.”
“7 Asgari MM, Brasky TM, White E. Association of vitamin A and carotenoid intake with melanoma risk in a large prospective cohort.”
“ Serum retinol was correlated positively with carotenoids and among carotenoids with each other (all were P < 0.001).”
“Laboratory data suggest that intake of vitamin A and carotenoids , may have chemopreventive benefits against melanoma, but epidemiologic studies examining the association have yielded conflicting results.”
“Vitamin A toxicity has traditionally been thought of as being unlikely to result from provitamin A due to its relatively poor absorption efficiency and the fact that the conversion of carotenoids to vitamin A is highly regulated.”
Genetic–environmental interaction in a unique case of Muenke syndrome with intracranial hypertension“Our study suggests a bone sparing effect of retinol , to which the provitamin A activity of some carotenoids might have contributed.”
“The serum concentrations of five carotenoids were significantly lower in the patients than in the controls ( vitamin A , zeaxanthin: P < 0.001; alpha-, beta-carotene: P < 0.01; lutein: P < 0.05).”
“Partial correlations of each carotenoid with fasting retinol concentration indicated that beta-carotene had the highest correlation.”
“Evidence for breast cancer is more limited but protective associations with vitamin A from both carotenoid and preformed sources have been seen in several studies.”
