Minerals and gut health

Minerals and gut health

Ten percent or more of a GP’s working life can be spent in consultation with patients with digestive disorders (1), with nearly half (43%) of the UK population experiencing some form of digestive discomfort (2). Minerals can play a vital role in maintaining optimal gut health and supporting various functions within the digestive system. Here's a closer look at how specific minerals contribute to gut health:


1. Calcium:

Calcium is involved in the normal functioning of digestive enzymes. Enzymes are essential for breaking down food into smaller, absorbable components. Adequate calcium levels support proper digestion and nutrient absorption.


2. Magnesium:

Magnesium contributes to normal muscle function, including the smooth contractions and relaxations of the muscles in the digestive tract. This peristaltic movement helps propel food through the digestive system, promoting healthy digestion.


3. Zinc:

Zinc is crucial for maintaining the integrity of the gut lining and the mucosal barrier. A strong and healthy gut lining is essential for preventing the entry of harmful substances into the bloodstream and supporting overall gut health.


4. Iron:

Iron is involved in various physiological processes, including oxygen transport and energy metabolism. Proper oxygenation of tissues, including those in the gastrointestinal tract, is important for overall gut function. Iron also supports the function of the immune system. An optimal immune system contributes to the maintenance of a balanced and healthy gut microbiota.


5. Copper:

Copper plays a role in the formation of connective tissues, which are essential for maintaining the structural integrity of the digestive tract. It contributes to the health of the gut lining and supports the absorption of other minerals.


6. Selenium:

Selenium has antioxidant properties, helping to protect cells from oxidative stress. In the gut, oxidative stress can lead to inflammation and damage. Selenium's antioxidant function contributes to maintaining a healthy gut environment.


7. Potassium:

Potassium is an electrolyte that helps balance fluid levels in the body, including the digestive tract. Adequate potassium levels support proper muscle contractions and the movement of food through the digestive system.


8. Sodium:

Sodium, another electrolyte, plays a role in maintaining fluid balance and supporting nerve impulses, which are essential for muscle contractions, including those in the digestive tract.


Eating a balanced and varied diet can help you obtain a full spectrum of nutrients. Dietary sources of these minerals include dairy products, leafy greens, nuts, seeds, whole grains, lean meats, and seafood. You may also wish to take a supplement to support your daily intakes with guaranteed nutrient levels.

If you have specific concerns about your gut health or mineral intake, it's advisable to consult with a healthcare professional or a registered dietitian who can provide personalized advice based on your individual needs and health status.
