![]() In our most recent blog post, we discussed the importance of vitamins such as vitamin K2. Another crucial vitamin for healthy gut functions is vitamin D. Vitamin D represents a group of fat-soluble vitamins which are required for increasing intestinal absorption of calcium, iron, magnesium, phosphate, zinc (1). The most important in humans are vitamins D2 and D3. While this vitamin is often associated with the skin, it can be acquired from food intake just as well as from sunlight. A study recently showed that a deficiency in vitamin D changes the intestinal microbiome and reduces vitamin B production in the gut. This means that there is a change in the type of bacteria living in our gut when we do not have enough vitamin D in our system (2). Furthermore, this lack of vitamin B leads to negative changes in our immune system. Our bodies suffer from increased inflammation and this can lead to autoimmunity – meaning our immune system is attacking healthy tissues and cells. Finally, low levels of vitamin D have been linked with an increased risk of depression. Not only is this vitamin important for a healthy gut and a strong immune system, but also our mental health (3). It really is a molecule with several, diverse effects. Others include bone health, cancer, cardiovascular disease, cognition/dementia, pregnancy, and weight loss as well. Therefore, it is very important to maintain normal levels of vitamin D in our blood. What can you do?
