It is likely safe for most people to take beta-carotene in small doses for a short time, but it may increase the risk of cancer, stroke, and other health problems in smokers and people with a history of asbestos exposure.N1-N7 Large amounts of beta-carotene should not be taken, especially by women who are pregnant or breastfeeding.
