What is Non-Celiac Gluten Sensitivity (NCGS)?

Non-Celiac Gluten Sensitivity (NCGS) is still a relatively unknown but real condition where people develop symptoms after eating gluten — without having celiac disease or a wheat allergy. Typical complaints vary widely but often include stomach pain, bloating, diarrhea, fatigue, brain fog, and sometimes muscle or joint pain (Fasano, 2013).

Prevalence

Estimates vary, but researchers such as Dr. Carlo Catassi and Dr. Alessio Fasano believe that about 3 to 6% of the population may fall somewhere on the NCGS spectrum (Catassi et al., 2015). That means millions of people worldwide may be walking around for years with vague, unexplained symptoms. Unlike celiac disease, there is (so far) no reliable biomarker: NCGS is a diagnosis of exclusion, which makes the search for answers frustrating and lengthy for many.

Challenges & Misunderstandings

Because there is no objective test, people with NCGS often encounter misunderstanding — from doctors, family, or colleagues. “It’s all in your head” is still a phrase many hear. Yet placebo-controlled studies (such as Biesiekierski et al., 2011) show that gluten can indeed cause significant symptoms in some people without celiac disease.

On top of that, the gluten-free range in some countries is still limited, and it can be tricky to ensure that a product is truly gluten-free.

Health benefits of living gluten-free

For those who are genuinely sensitive, living gluten-free can make a world of difference. Many people with NCGS experience significant improvements within days to weeks: more energy, clearer thinking, and calmer digestion. It’s worth noting: a gluten-free diet isn’t a miracle solution for everyone — but for those whose symptoms are truly triggered by gluten, it can dramatically improve quality of life, work enjoyment, and social wellbeing (Fasano, 2013).

At GLUTEN TAG, we understand this better than anyone. That’s why we make gluten-free beer more accessible — because even without gluten, you deserve to enjoy a proper pint!

Why gluten-free?

Improved Digestion

Many people experience bloating, discomfort, or
sluggish digestion after eating gluten.
Avoiding gluten can help improve gut health,
reduce inflammation, and promote better nutrient absorption.
A gluten-free diet may also support those
with sensitive stomachs or mild intolerances.

More energy

Gluten can contribute to
energy crashes and brain fog,
especially for those with sensitivities.
Cutting back on gluten may lead to more
stable energy levels, better focus,
and reduced feelings of sluggishness
throughout the day.

Skin health

Gluten sensitivity has been linked to skin conditions
like acne, eczema, and rashes. Reducing gluten
intake may help promote clearer skin, as it decreases
inflammation and supports better digestion,
which is key for overall skin health.

Healthier gut

Gluten can be hard to digest and may disrupt gut
bacteria balance. A gluten-free diet can support
a healthier microbiome, improve digestion, and reduce
bloating, making it easier for your body to
absorb essential nutrients.
