Neither supplementation group was significantly different from placebo in all-cause maternal mortality (vitamin A: RR 1.2; 95% CI, 0.75–1.8; and betacarotene: RR 1.2; 95% CI, 0.81–1.8). Vitamin A significantly reduced gestational night blindness (7.1% for vitamin A, 8.9% for beta-carotene...
For example, many plants contain beta-carotene, which is converted to vitamin A by many animal species (and humans). However, cats cannot utilize beta-carotene to make Vitamin A, therefore, it is wrong to assume that cats can derive vitamin A from plants that are high in the vitamin. ...
In addition to vitamin C, papayas are also abundant in vitamin A, vital for maintaining eye health. This is mainly derived from the high content of beta-carotene, which the body converts into vitamin A. The vibrant orange color of the papaya flesh is a clear indicator of its beta-carotene...

Vitamin AThe central cleavage of β-carotene to vitamin A purportedly involves a dioxygenase that may be copper dependent. Therefore, the purpose of this study was to determine the effect of copper (Cu) deficiency on the conversion of β-carotene to vitamin A as measured by total liver ...
Maternal vitamin A or beta-carotene supplementation in lactating Bangladeshi women benefits mothers and infants but does not prevent subclinical deficiency. J Nutr 1999;129:356-65.Rice, A. L., R. J. Stoltzfus, A. de Francisco, J. Chakraborty, C. L. Kjolhede, and M. A...
The aim of the study was to examine the potential effects of coenzyme Q10 (CoQ10) on reproductive function in a chronic kidney disease (CKD) mouse model. Nine-week-old mice were randomly assigned to two groups: sham surgery (n = 18) and CKD surgery (n = 18). After surgery, the stud...
