How Bioavailability Affects Your Nutrition
Nutrients need to have good bioavailability for your body to be able to use them
When it comes to your nutrition, the actual vitamin or mineral content of a given food is less important than the amount of those vitamins or minerals that your body can absorb and use.
Now you may wonder…
…why is there a difference?
It’s due to a concept called bioavailability. Nutrients that are highly bioavailable are easy to digest and absorb. This means it is easy for the nutrients to get freed from the food that contained them and for the nutrients to then get absorbed from the digestive tract and transported to other parts of the body. Nutrients that are poorly bioavailable are difficult to digest and/or absorb. This means that a significant portion of the nutrients may pass through your system and get excreted without being used.
Four Ways to Improve Bioavailability
Fortunately, there are ways to up your intake of nutrients that have poor bioavailability. Depending on the properties of the nutrient in question, it may be possible to use one of the following strategies:
Consuming More Nutrients: Perhaps the simplest way to compensate for poor bioavailability is simply to consume a greater amount of a given nutrient. This strategy is behind the high doses of nutrients found in many multi-vitamins and supplements.
Pairing Nutrients: The nutrients in foods can interact with each other and affect bioavailability. For example, the absorption of magnesium and calcium can be improved by pairing them with Vitamin D. You can improve your zinc absorption by pairing it with dietary protein, and you can get more beta-carotene by pairing veggies rich in this nutrient with healthy fats like avocado or olive oil.
Supplementing the Correct Form of a Nutrient: Many nutrients—especially minerals—can be found in different chemical forms in different foods. The chemical form can have a dramatic impact on bioavailability. For example, iron comes in two chemical forms, heme iron and non-heme iron. Heme iron, which is found in meat, is much more bioavailable than non-heme iron, which is found in plants. On a side note, absorption of non-heme iron is inhibited by calcium, but it can be improved by pairing it with Vitamin C.
Injectable Nutrients: While vitamins and minerals can pass through the stomach without being harmed by stomach acid, other nutrient compounds will be severely damaged or destroyed. For example, L-Glutathione is a powerful antioxidant that is very effective in fighting chronic inflammation. It’s difficult to get this nutrient from food because stomach acid damages it. However, when taken in an injectable form, this nutrient becomes perfectly bioavailable and it is easy to reap all its health benefits.
