Possible Interaction: Carotenoids and Zeaxanthin

“Increased macular carotenoid levels result from supplementation of humans with lutein and zeaxanthin.”

“Findings from L-ZIP will strengthen recommendations regarding prenatal carotenoid supplementation and consequently inform policy decisions.”

“Similarly, dietary total carotenoids and specific carotenoids, α‐carotene, β‐carotene, and lutein/zeaxanthin were inversely associated with hip fracture risk.”

“We hypothesized that increased consumption of eggs, lutein, and zeaxanthin may correlate with decreased absorption of other carotenoids and increased absorption of vitamins A and E, thus affecting their serum concentrations and lipoprotein distribution.”

“Here, we examined if LUT and ZEA attenuate the bioaccessibility of pro-VA carotenoids at amounts and ratios present in maize.”

“Increasing zeaxanthin in common foods such as potatoes by traditional plant breeding or by genetic engineering could contribute to an increased intake of this carotenoid and, consequently, to a decreased risk of age-related macular degeneration.”

“ Carotenoids were twice as effective at mediating zeaxanthin accumulation when provided to larvae versus adults.”

“This resulted in a proportional increase of zeaxanthin from 22% to 70% of the total carotenoid present.”

“Results: Zeaxanthin induces a red shift in the carotenoid triplet excited state spectrum and reveals a higher efficiency in controlling chlorophyll triplet formation.”

“The quantity of carotenoids calculated on a Chl basis increased differentially with nostoxanthin, cryptoxanthin, zeaxanthin and beta-carotene showing 2.6-, 3.1-, 1.9- and 1.9-fold increases, respectively, while the relative amount of caloxanthin was increased only by 30%.”
