Vitamin A plays important roles in genetic expression, embryonic development, organ formation during fetal development, normal immune function, eye development, and vision.
WeNatal for Her includes two forms of vitamin A: mixed carotenoids, which are the plant-based family of vitamin A compounds found in nature (including beta-carotene, lutein, zeaxanthin, and lycopene), and preformed vitamin A as palmitate, which is readily absorbed and used by the body.
Some people have a difficult time converting carotenoids into active (palmitate) vitamin A. However, high intakes of preformed vitamin A can accumulate in the body, which is why we carefully balance the two forms as the body converts carotenoids on an as needed bases.
WeNatal for Her provides 990 mcg RAE from mixed carotenoids and 1,210 mcg RAE from vitamin A palmitate recommended by current research. This combination helps support vitamin A needs during preconception and pregnancy while keeping the amount of preformed vitamin A well below the established adult tolerable upper intake level of more than 3,000 mcg RAE [10,000 IU] daily from preformed vitamin A.
Mixed carotenoids have not been linked to the same concerns as high-dose preformed vitamin A, because the body regulates their conversion based on need. Still, we recommend being mindful of additional concentrated sources of preformed vitamin A, especially liver, cod liver oil, or high-dose vitamin A supplements, so total daily intake stays within safe limits unless otherwise directed by a healthcare provider.
