What is Bioavailability?
A brand new animation for Future You Cambridge exploring the little known subject of Bioavailability – looking at how supplements that are formulated to have high bioavailability will be more effective for your body.
A substance will only take effect if it can be absorbed by the body, so bioavailability is the key to creating a supplement that delivers proven benefits.
Bioavailability is a measure of how much a substance is able to access the circulation and reach the target area, and it depends on absorption (how much we get it) and secretion (how much we get out).
Nutritional scientists are well aware of the importance of bioavailability. For example, when you eat, the food is taken into your digestive system. Useful nutrients are then absorbed into your bloodstream and are either stored or used by your cells. However, because your body is not perfectly efficient, not all the nutrient molecules will be absorbed: some are destroyed in the stomach and intestines, some are excreted back, and some simply just don’t go inside the cells.
Macronutrients such as carbs and fats are highly bioavailable, but the beneficial micronutrients commonly sold as supplements – vitamins, minerals, flavonoids and carotenoids – can sometimes be harder to absorb by the body.
Supplements that are formulated to have high bioavailability will be more effective, as they will help the body to absorb more of the appropriate nutrient, without having to take higher doses. There are multiple methods to increase bioavailability of active ingredients, but most of them will focus on increasing absorption rather than decreasing secretion.
