5 Vitamins You May Need if You’re Gluten-Free

Key Takeaways:

  • B-vitamins, iron, vitamin D, and calcium are all important nutrients that you may need more of if you are following a gluten-free diet.

Following a gluten-free diet may allow you to feel your best, but there’s a chance that you are missing out on certain key nutrients — especially if you suffer from celiac. Celiac disease can affect your body’s ability to absorb essential nutrients. And many foods that contain gluten are also fortified with essential vitamins and minerals that are not present in gluten-free products.

Thankfully, taking a quality supplement is an easy way to fill in nutritional gaps. Let’s take a look at the most important vitamins and nutrients you may need if you have a gluten-intolerance or sensitivity. Or, dive right in and explore all of our gluten-free supplements!


Why vitamin deficiencies are more common in people with celiac disease

Celiac disease is a digestive disorder characterized by an inflammatory reaction to gluten. When a person with celiac disease consumes gluten, the immune system mistakenly attacks the small intestine, causing damage to the villi, which are finger-like structures that help absorb vitamins and nutrients.1

If celiac disease is left untreated for a long time, it can cause enough damage to the small intestine that it can no longer absorb nutrients. This causes malabsorption.

Malabsorption is to blame for nearly all nutritional and vitamin deficiencies in celiac patients.
When a healthy person takes vitamins or eats nutritious foods, they are usually digested in the stomach and then moved to the small intestine, where vitamin absorption occurs.

If you have celiac disease, however, malabsorption means that most vitamins aren’t absorbed by the small intestine, and end up in the rectum instead.


1. Folate

Folate, or folic acid, is one of the B-complex vitamins. Folate is essential during pregnancy to help prevent birth defects, but everyone needs sufficient amounts of folate to help their bodies make new cells.

Many gluten-containing foods are fortified with extra folate. Gluten-free grain products, however, are made of neither whole grains nor enriched grains. Gluten-free grain products often replace gluten-containing whole or enriched grains with starches, which don’t contain folate.

If you’re eating gluten-free, you’ll need to take special care to make sure you’re getting enough folate.

Which gluten-free foods contain folate?

If you’re trying to eat more folate, think green. Spinach, asparagus, and brussel sprouts are all good sources of folate, as well as green peas and broccoli.

Taking a folate supplement is also an easy way to get your daily dose of folate.

This gluten-free folate supplement supports prenatal health, heart and nervous system health, DNA and RNA production, and more.* And it’s also non-GMO, vegan, dairy-free, and kosher.


2. B-Vitamins

The B-vitamin complex is made up of eight water-soluble B-vitamins that play a number of essential roles in the body, including supporting energy metabolism and the growth and development of cells.*

Because B-vitamins are often added to processed, wheat-based foods in the fortification process but are not usually added to gluten-free foods. People who follow a gluten-free diet may not be getting enough of these essential nutrients, in particular, vitamins B6, B9 (folic acid), and B12.

Which gluten-free foods contain B-vitamins?

B-vitamins can be found in a variety of foods, including dark leafy greens, fatty fish, beans, nuts, and poultry. Since vitamin B12 is mainly found in animal foods, vegans may struggle to get enough of this vitamin.

The easiest way to fill in any nutritional gaps caused by a gluten-free diet is to take a B-vitamin supplement.

3. Iron

Anemia, or iron deficiency, is one of the most common symptoms of celiac disease — especially in elderly people. 60-80% of elderly patients with celiac disease also had an iron deficiency.2

Again, this can be attributed to the damage to the intestinal lining of the small intestine, which causes malabsorption.3

Even without dietary restrictions, many people struggle to get enough iron. If you have a gluten intolerance and follow a gluten-free diet, you are even more likely to be lacking in this important mineral.

Like B-vitamins, iron is added to many fortified processed wheat foods and is not usually added to gluten-free products. Studies have shown that people who follow a gluten-free diet show greater signs of a deficiency in iron.4

Which gluten-free foods contain iron?

Gluten-free food sources of iron include dark leafy greens, red meat, egg yolks, and nuts and seeds.5

The easiest way to ensure you’re meeting your daily iron needs is to take a quality iron supplement.

4. Vitamin D

Vitamin D is essential for supporting a healthy immune system, strong teeth and bones, and more. Yet 64% of men and 71% of women with celiac disease have a vitamin D deficiency.6

For celiac patients, damage to the gut lining (also known as villous atrophy) causes malabsorption of vitamin D.

And, because vitamin D helps the body absorb calcium, malabsorption of vitamin D can also lead to a calcium deficiency.7

Sunshine is the body’s main source of vitamin D, but it is not the only source. Vitamin D can also be found in fortified dairy and cereals, and oatmeal products. If you are gluten-free (or dairy-free) you may not get enough vitamin D.

Which gluten-free foods contain vitamin D?

Unfortunately, few foods contain much vitamin D. Cold-water fish like swordfish and sockeye salmon are the exceptions, which contain substantial amounts of vitamin D. However, the easiest way to get adequate amounts of body-ready vitamin D is to take a supplement.

5. Calcium

Calcium is an essential mineral for healthy bones and teeth, nerve health, and more.8

However, approximately 75% of newly diagnosed celiac disease patients have reduced bone mineral density due to inadequate calcium absorption.9

Thankfully, there are many food options with ample calcium.

Which gluten-free foods contain calcium?

Gluten-free sources of calcium include dairy products such as milk, yogurt, and cheese and certain vegetables such as kale and broccoli. The easiest way to ensure you’re getting enough calcium is to take a calcium supplement that offers magnesium, which helps absorption.
