Vitamins & Minerals
Our genes make us unique in lots of ways — one of which is how we absorb and utilize vitamins and minerals from our food.
Take, for example, eating carrots to get your daily vitamin A. Some people are great at converting beta-carotene, the precursor to vitamin A in vegetables, into the form of vitamin A that the body uses. Other people carry genetic variants that make that conversion process difficult.
Instead of wondering, you can simply check your genetic data to see which form of vitamin A is best for you.
