Can Probiotics Help Eczema? Understanding the Gut-Skin Connection

Eczema affects millions of people worldwide, causing dry, itchy and inflamed skin that can have a significant impact on daily life. While creams and medications remain important treatments, researchers are increasingly exploring another area that may influence skin health—the gut.

This has led many people to ask: can probiotics help eczema?

Although probiotics are not considered a cure for eczema, growing research suggests that the health of your gut microbiome may play an important role in supporting the immune system and maintaining healthy skin. Understanding the connection between the gut and the skin may help explain why diet and digestive health are becoming an important part of conversations around eczema management.

What Is Eczema?

Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition. It often causes:

• Dry skin
• Redness
• Itching
• Cracked skin
• Flare-ups that come and go

Eczema develops through a combination of genetics, immune function and environmental triggers. Common triggers include allergens, stress, harsh soaps, weather changes and, in some people, certain foods.

Although eczema appears on the skin, researchers now understand that the immune system plays a central role in the condition.

What Are Probiotics?

Probiotics are live microorganisms that may help support a healthy balance of bacteria within the gut when consumed in adequate amounts.

Your digestive system contains trillions of bacteria, fungi and other microorganisms collectively known as the gut microbiome. These microbes help:

• Support digestion
• Produce beneficial compounds
• Communicate with the immune system
• Help maintain the gut barrier

A healthy microbiome is increasingly recognised as an important part of overall wellbeing.

Understanding the Gut-Skin Connection

The gut and the skin constantly communicate through what researchers call the gut-skin axis.

When the gut microbiome is balanced, it helps support normal immune function and contributes to the production of beneficial compounds such as short-chain fatty acids, including butyrate. These compounds help nourish the cells lining the intestine and support the integrity of the gut barrier.

If the balance of bacteria is disrupted, the immune system may respond differently, potentially influencing inflammatory processes throughout the body, including the skin.

This doesn't mean poor gut health causes eczema on its own, but it may be one of several factors that influence symptoms in some individuals.

Can Probiotics Help Eczema?

Current research suggests that probiotics may help some people with eczema, but the results are mixed.

Some studies have found improvements in eczema severity, particularly in children and when certain probiotic strains are used. Other studies have found little or no benefit.

Because different studies use different probiotic strains, doses and treatment durations, it is difficult to make one recommendation that applies to everyone.

For this reason, probiotics are generally viewed as a possible supportive approach rather than a replacement for conventional eczema treatments.

Fermented Foods and Gut Health

One natural way to support your gut microbiome is by regularly including fermented foods in your diet.

Examples include:

• Water kefir
• Live yoghurt
• Sauerkraut
• Kimchi
• Kefir
• Kombucha
• Traditionally fermented vegetables

These foods naturally contain beneficial bacteria that contribute to dietary diversity. Eating a varied diet rich in fibre and fermented foods may help support a healthy microbiome over time.

Other Ways to Support the Gut

Looking after your gut involves much more than taking a probiotic supplement.

Simple lifestyle habits that support gut health include:

• Eating plenty of fibre-rich vegetables
• Including fermented foods regularly
• Limiting ultra-processed foods where possible
• Getting enough sleep
• Managing stress
• Exercising regularly
• Staying hydrated

Together, these habits help create an environment where beneficial gut bacteria can thrive.

What About Bone Broth?

Bone broth has become increasingly popular among people interested in gut health.

Traditionally made by slowly simmering bones over many hours, bone broth naturally contains collagen, gelatin and amino acids. While more research is needed, many people choose to include bone broth as part of a varied, balanced diet focused on supporting overall wellbeing.

Bone broth should not be viewed as a treatment for eczema, but it can be a nourishing addition to a healthy eating pattern.

Frequently Asked Questions

Which probiotic is best for eczema?

There is currently no single probiotic that has been shown to work for everyone. Different strains appear to produce different results, and research is still ongoing.

Can improving gut health cure eczema?

No. Eczema is a complex condition influenced by genetics, the immune system and environmental factors. Supporting gut health may help overall wellbeing, but it should not be considered a cure.

Are fermented foods better than probiotic supplements?

Both have their place. Fermented foods provide naturally occurring beneficial bacteria as part of a healthy diet, while probiotic supplements contain selected strains in measured amounts.

Can children take probiotics for eczema?

Parents should always seek advice from a healthcare professional before giving probiotic supplements to young children, particularly if they have underlying medical conditions.

Final Thoughts

Interest in the connection between gut health and eczema continues to grow as researchers learn more about the gut microbiome and its relationship with the immune system.

While probiotics are not a cure for eczema, maintaining a healthy gut through a balanced diet, fermented foods and healthy lifestyle habits may help support overall wellbeing. When combined with appropriate medical care, these habits can form part of a holistic approach to looking after both your gut and your skin.
