What percentage of vitamins in foods does our body absorb?

The percentage of vitamins that our body absorbs from food varies depending on the type of vitamin and the individual’s overall health and nutrient status.

The absorption of vitamins can be affected by several factors:

  1. Bioavailability of the vitamin: Some vitamins have higher bioavailability, meaning they are more easily absorbed and utilized by the body. For example, fat-soluble vitamins like vitamins A, D, E, and K are better absorbed when consumed with dietary fat.

  2. Food preparation and processing: The way food is cooked or processed can affect the bioavailability of vitamins. For instance, overcooking vegetables can lead to vitamin loss, while raw or lightly cooked vegetables retain more of their vitamin content.

  3. Individual factors: Each person’s ability to absorb vitamins can vary based on factors such as age, gut health, and any medical conditions they may have. Certain medical conditions, like malabsorption disorders or gastrointestinal diseases, can impair vitamin absorption.

  4. Interactions with other substances: Some substances can enhance or inhibit vitamin absorption. For example, vitamin C can enhance the absorption of non-heme iron from plant-based foods, while substances like tannins in tea can inhibit iron absorption.

It’s important to note that even if we consume foods rich in vitamins, our body may not absorb all of the vitamins present in those foods. The absorption rates can range from 10% to 90% depending on the vitamin and individual factors.

To maximize vitamin absorption, it’s advisable to consume a varied and balanced diet, including a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. Additionally, cooking methods that preserve nutrients, such as steaming or sautéing, can help retain more of the vitamins in foods. If you have concerns about your vitamin absorption, it is always a good idea to consult with a healthcare professional or a registered dietitian for personalized advice.
