Flavonoids in fruits and veggies have health benefits, but how our bodies absorb them is important. Factors like the type of flavonoid, its structure, and what else we eat can affect how much we absorb. Other things like how much we take, how we take it, our diet, our genes, and the bacteria in our gut also play a role. Studies have shown that these factors can impact how well our bodies absorb and use flavonoids.
