A few years ago, if you heard the term “gut health,” most people would have either rolled their eyes and said you were crazy or just scratched their heads in confusion.

Now, though, many people, especially health-conscious folks, have at least a cursory idea of the importance of prioritizing the health of your digestive tract (also known as your gut).

While the idea of gut health is becoming mainstream, there’s still a lot of confusion out there when it comes to actually keeping your gut lining healthy and intact. If you’re not sure where to begin when it comes to working toward getting a healthy gut, start by adding these five vitamins and minerals to your diet.

1. Iron

Iron is an essential mineral that is necessary for healthy red blood cells. It also plays a major role in supporting the good bacteria in your digestive tract.

One study found that iron supplementation helps increase the number of good bacteria in the gut. It also increased the amount of butyrate — an anti-inflammatory bacterial metabolite — in the gut.

Iron is especially beneficial to women, who tend to be iron deficient (especially women who menstruate regularly).

You can get iron naturally from red meat, egg yolks, and leafy greens like spinach. The body has an easier time absorbing iron from animal products, though.

Before you start trying to increase your iron consumption or start taking an iron supplement, it’s important to get your iron levels tested. Too much iron can create serious health problems.

2. Vitamin C

If you want to absorb the iron you’re consuming, it’s important to also make sure you’re consuming adequate amounts of vitamin C.

Vitamin C is an antioxidant that promotes a healthy immune system (the majority of which is found in your gut) and reduces inflammation throughout the body, including in the digestive tract. It also aids in digestion since it supports healthy gums and teeth.

You can find vitamin C in citrus fruits (oranges, grapefruits, etc.), berries, broccoli, and peppers. You can also get it from nutritional supplements, although most people find they get sufficient vitamin C from food alone.

3. Vitamin D

Vitamin D is another vitamin that plays an important role in proper immune system functioning. Low vitamin D levels have also been linked to increased rates of inflammatory bowel disease. People with chronically poor digestion can see great benefits by supplementing with vitamin D.

Most people can benefit from vitamin D supplementation.

You can get vitamin D from the sunshine, and from foods like salmon and egg yolks. But, most people don’t spend enough time outside or consume enough of these foods to reach sufficient levels, so supplements can improve your gut health and keep you feeling your best.

4. Zinc

Zinc is a mineral that helps the body produce digestive enzymes, which are necessary for breaking down and absorbing nutrients.

Research shows even a mild and/or temporary zinc deficiency can create digestive disorders and reduce the production of digestive enzymes.


People who are diabetic, have parasitic infections or malabsorptive disorders, and those who consume large amounts of fiber tend to be low in zinc. Common symptoms of low zinc include:

  • Diarrhea
  • Low appetite
  • Skin issues like acne and dry skin

Zinc is found in oysters, beef, lamb, and organ meats (specifically beef and pork liver).

5. Vitamin E

Vitamin E is another antioxidant that helps reduce inflammation. It helps heal intestinal permeability (also known as leaky gut syndrome), too, and it improves fat absorption and your absorption of fat-soluble vitamins like vitamin A and vitamin D.

Men, in particular, need to make sure they’re consuming sufficient amounts of vitamin E, as it can also help prevent prostate cancer. That’s why it’s often found in vitamins designed specifically for men.

Vitamin E is present in most multivitamins. But, you can also get it from foods like hazelnuts, sunflower seeds, and almonds.

Final Thoughts

You can significantly improve your gut health by adding these five vitamins and minerals into your diet. Before you go out and buy a bunch of fancy supplements, start by covering your bases with these easy-to-get nutrients.
