BOOST GUT & SKIN HEALTH WITH Advanced Gut & Skin Barrier Support Bundle (12+)

Leaky gut is also known as increased intestinal permeability. It occurs when the gut lining becomes more porous than it should be, allowing toxins, food particles and microorganisms to escape the intestinal tract leading to inflammatory responses.

Research suggests that leaky gut may be associated with various dermatological conditions like eczema.  For example, some studies have found that children with eczema have increased leaky gut relative to those without eczema, and one study found a correlation between a marker of increased gut permeability and the eczema SCORAD index.  

So a robust gut lining and barrier mean healthier skin.  Rebalance and fortify your gut with this specially designed prebiotic and probiotic combination.

Eczema can be associated with a weakened skin barrier, changes in the skin and gut microbiome, and an impaired gut barrier. The Bia supplements and topicals are formulated to support eczema from the inside and out.
