Paprika carotenoids capsanthin and capsorubin and their biological effects

What it found

Paprika's main carotenoids, capsanthin and capsorubin, act as strong antioxidants and may help prevent obesity-related diseases.

They are absorbed into the blood and found in red blood cells.

What they found

Studies in people

Absorption in the body

Carotenoids from dietary paprika are absorbed into the blood and are detected in red blood cells.

Athletic endurance

They help raise athletes' endurance by lowering oxygen consumption and heart rate.

Animal and lab studies

Antioxidant effect

Capsanthin and capsorubin, the carotenoids typical of paprika, show a strong antioxidative effect.

Obesity-related disease prevention

These carotenoids show a preventive effect on diseases related to obesity.

What the authors conclude

“Dietary paprika carotenoids are absorbed in blood, and they are detected in erythrocytes.”
Maeda H, Nishino A, Maoka T, 2021

Also in their conclusions

  • They report that paprika carotenoids are absorbed in blood and detected in erythrocytes.
  • They state that this contributes to upregulate endurance performance of athletes by reducing oxygen consumption (VO 2 ) and the heart rate.

How it was done

Paprika contains several carotenoids, and capsanthin and capsorubin are the ones most characteristic of paprika.

What it can’t tell you

  • We summarised it from the abstract only.
  • This summary is based only on the abstract, so details of how the studies were done are not available.
  • It is not clear from the abstract whether the findings on obesity-related diseases and endurance come from people, animals or lab tests.
