My favorite B vitamin with Niacin (B3) –

The niacin your body uses comes from food. But your liver also makes niacin from the amino acid (smallest unit of protein) tryptophan. Therefore, it’s important to consume both niacin and tryptophan.

Niacin can be absorbed through your stomach, but a majority is absorbed through your small intestine. And this presents a problem for those with gluten sensitivity. Because gluten damages the lining of the small intestine, which leads to incomplete digestion and nutrient malabsorption.

We know that those with celiac disease experience vitamin and mineral deficiencies, especially before implementing a gluten-free diet. And intestinal malabsorption is a proposed mechanism of pellagra, a disorder caused by niacin deficiency.

In addition, diarrhea is a common symptom of gluten sensitivity. This can further contribute to a niacin deficiency as the niacin is flushed out of the body instead of being absorbed.

Plus, gluten-induced malabsorption increases your risk of copper deficiency. And copper deficiency can affect the conversion of tryptophan to niacin in your liver.

It’s also important to note that hormones (e.g., insulin and estrogen) modulate the pathway used to convert tryptophan to niacin. And gluten can disrupt the balance of these hormones.

Thus, a gluten-free diet is essential for those with gluten sensitivity to prevent pellagra. Symptoms to look out for include:

Numbness/pain in hands and feet
Mood swings
Mental confusion/dementia
Gas and bloating
Diarrhea or constipation
Mouth sores
Skin inflammation
Tongue inflammation (glossitis)
Hair loss
Sensitivity to sunlight
If left untreated, pellagra can be deadly. So please don’t ignore these symptoms if you have them!

Eating disorders, alcoholism, AIDS, and cancer can also increase your risk of developing pellagra.
