What is better alpha or beta carotene? Alpha and beta carotene are similar substances however alpha carotine has some advantages over beta carotene in inhibiting tumor formation. So, a research study looked at blood serum levels of alpha-carotine and mortality. This study included an analysis of 15,318 adults of age 20 or older. It was found that higher blood levels of alpha-carotine were associated with a lower risk of death from cardiovascular disease as well as cancer and other factors. Where can I get some? There are high concentrations of alpha-carotine in yellow-orange vegetables such as carrots, sweet potatoes, and pumpkins and dark-green vegetables such as broccoli, and spinach. These foods also have high concentrations of beta carotene as well so eating veggies is a win win situation!
