Eczema Often Begins in the Gut – Not on the Skin
If eczema keeps returning no matter how many creams you use, the real cause may be hidden deep inside your gut.
New research confirms the powerful connection between:
- gut bacteria
- immune response
- inflammation levels
- skin barrier strength
This communication network is called the gut–skin axis — and when the gut becomes inflamed or imbalanced, the skin almost always reacts.
Eczema, rashes, itching, and redness are often external symptoms of internal inflammation.
Let’s break down how it works — and the most effective ways to calm eczema naturally by supporting gut health.
1. The Gut–Skin Axis Explained
Your gut and skin communicate through:
- the immune system
- hormones
- inflammation signals
- microbial metabolites
When the gut lining becomes irritated or “leaky,” inflammatory molecules escape into the bloodstream.
This triggers systemic inflammation that often shows up on the skin as:
- eczema
- dermatitis
- dry patches
- itching
- redness
Simply treating the skin rarely works long term because the issue begins deeper — in the gut.
2. How Gut Inflammation Triggers Eczema
Here’s what happens beneath the surface:
▪ Imbalanced bacteria (dysbiosis)
Harmful bacteria release toxins that increase inflammation.
▪ Leaky gut
Gaps in the gut lining allow irritants into the bloodstream → immune reactions → skin flare-ups.
▪ Poor nutrient absorption
Low levels of zinc, vitamin A, and omega-3s weaken the skin barrier.
▪ Elevated immune response
The immune system becomes overactive, creating chronic redness and irritation.
▪ Histamine overload
Certain bacteria trigger histamine release, worsening eczema itchiness.
3. Foods That Calm Gut Inflammation (And Help Eczema)
Add more of these gut-soothing foods:
- leafy greens
- bone broth
- berries
- fatty fish (salmon, sardines)
- turmeric
- ginger
- kefir and yogurt
- sauerkraut and kimchi
These support your microbiome and reduce inflammatory load.

4. Foods That Make Eczema Worse
Reduce or eliminate:
- sugar
- processed seed oils
- deep-fried foods
- alcohol
- dairy (if sensitive)
- artificial sweeteners
These feed harmful bacteria and irritate the gut lining.
5. Probiotics and Eczema: How They Help
Probiotics help restore a healthy gut microbiome, which:
- lowers inflammation
- improves skin hydration
- strengthens the skin barrier
- reduces eczema flare frequency
The most researched strains include:
- Lactobacillus rhamnosus GG
- Bifidobacterium longum
- Lactobacillus plantarum
These strains reduce inflammatory skin responses and improve barrier function.

Formulated with gut-calming strains to support eczema-prone skin from the inside out.
6. Repairing the Gut Lining for Better Skin
Include daily:
- bone broth
- L-glutamine
- zinc
- omega-3s
- polyphenol-rich foods
- prebiotic fiber
These help rebuild the gut barrier, reducing the internal inflammation that drives eczema.
7. Stress, Sleep & the Eczema Connection
Stress increases cortisol, which:
- weakens the gut barrier
- disrupts microbiome balance
- worsens eczema flare-ups
Improving sleep and stress management helps calm both the gut and the skin.

Yes — certain strains reduce inflammation and strengthen skin barrier function.
5. What probiotic strains are best for eczema?
Lactobacillus rhamnosus GG, Lactobacillus plantarum, and Bifidobacterium longum.
6. Does leaky gut affect eczema?
Definitely — leaky gut allows inflammatory particles into the bloodstream, worsening skin irritation.
