Beta-carotene, a vital nutrient, undergoes conversion into vitamin A within the body. This vitamin holds significant importance for vision, bolstering the immune system, facilitating cell growth, and maintaining healthy skin. Both vitamin A and beta-carotene function as antioxidants, shielding cells against harm from free radicals. Although primarily dictated by dietary intake, beta-carotene levels may also be marginally influenced by genetic factors. The TenDNA health report offers insights into whether individuals with genetic profiles akin to yours typically exhibit typical levels of vitamin A. Decreased levels of carotenoids and tocopherols in the bloodstream are linked to a higher likelihood of chronic illness and disability. Given the weak correlation between dietary consumption of these lipid-soluble antioxidant vitamins and plasma levels, we theorized that genetic variance may impact the presence of circulating carotenoids (related to vitamin A) and tocopherols (related to vitamin E).
