Mixed Carotenoids, Beta-Carotene and Clearance of HPV

By admin April 11, 2018

Mixed carotenoids are a group of nutrients that include beta-carotene, lycopene, lutein astaxanthin, zeaxanthin and many others.

Found in fruits and vegetables, these nutrients are potent antioxidants; they protect DNA from oxidative damage which may lead to potential cancer-causing mutations, and beta-carotene converts into Vitamin A in the body.

Research shows that low levels of carotenoids in the body play a role in the developments of cervical dysplasia and HPV, while higher levels are associated with a lower risk of HPV progression.

A recent study in the Journal of Nutrition and Cancer compared the effects of carotenoids on HPV persistence using circulating and dietary nutrient levels and found that there was a 50% higher risk observed for women with low dietary carotenoid levels. These results are consistent with the current research that low levels of carotenoids increase the risk of persistent HPV infection.

Antioxidants, such as carotenoids, may reduce the viral load of HPV. Carotenoids are able to reduce the impact of ROS (reactive oxygen species), which cause cellular damage and increase viral replication, as well as improve the host’s cell-mediated immunity.

Carotenoids can be found in foods such as: carrots, sweet potatoes, dark leafy greens, tomatoes, squash, cantaloupe, sweet red peppers and dried apricots.

Making sure that you get an adequate amount of mixed carotenoids is very important to help prevent HPV persistence.

Unlike most beta-carotene supplements that are synthetically made, Papillex uses only mixed carotenoids from pristine water algae, ensuring that our customers have the full spectrum of carotenoids, from a whole food source.
