Ovulation is red

Researchers believe that this red pigment increases during ovulation because during ovulation, a woman's ovary releases an egg, which waits in the fallopian tube for fertilization. If a large amount of carotene accumulates in the ovaries, the eggs will be more likely to be fertilized.

In addition, there is an increase in a substance called "red pigment-3", which is called "carotenoid". Carotenoids, found in carrots, orange and red vegetables, may also help women better understand when they are ovulating.

While this finding may be helpful for women to better understand their cycles and the fertilization process, it's not a new one. Decades ago, it was discovered that the red pigment in vegetables and fruits can help improve vision. In addition, carotenoids in carrots and orange vegetables may also help reduce the risk of cancer.
