The Effects of Probiotics in Atopic Dermatitis
Probiotic, Prebiotic, and Postbiotic supplements seem to have a beneficial effect on Atopic Dermatitis. Specifically, Atopic Dermatitis and biotic use in the prevention. Be cautioned however, evidence to support the supplementation of the diet with probiotics for the management of Atopic Dermatitis is not enough.
A 2009 meta-analysis of 12 randomized trials including 781 participants found that probiotics were not more effective than placebo in reducing eczema symptoms and sleep disturbance.
The use of probiotics in this study shows that the supplement does not reduce the need for other treatments. This then calls for treatment via topical corticosteroids. Following the 2009 study, a meta-analysis of 25 randomized trials including 1600 participants found interesting evidence. This analysis reported that probiotics were associated with a modest, clinically insignificant reduction of the baseline Scoring of Atopic Dermatitis (SCORAD) score (1).
Atopic Dermatitis mechanism of injury, clinical signs, and diagnosis
We begin this discussion with answering, “What is Atopic Dermatitis?”:
Atopic dermatitis is a chronic pruritic inflammatory skin disease that occurs most frequently in children. It affects adults. AD is associated with elevated IgE and family history of eczema, asthma, and allergic rhinitis (known as atopy).
Who is affected by the atopy?
Atopic dermatitis affects approximately 5 to 20 percent of children worldwide. In the United States, the prevalence is approximately 11 to 15 percent (2, 3, 4). Approximately 70 percent of patients have a positive family history of atopic diseases.
How does AD Happen?
Either skin inflammation is initiated by skin barrier malfunction outside of the body (“outside-in” hypothesis) or by immune dysregulation inside the body (“inside-out” hypothesis). The jury is still not out on which theory is prevailing.
What does AD look like?
Dry skin and severe pruritus are the cardinal signs of atopic dermatitis. Clinical presentation is highly variable, depending upon the patient’s age and disease activity.
How do probiotics play a part in Atopic Dermatitis Treatment?
As you recall, Probiotic therapy with Lactobacillus and other organisms has been studied for the treatment of AD in infants and children but has proven to be of limited benefit. Probiotic supplementation in pregnant mothers and infants at risk for AD may prevent the development of the disease in children younger than three years. A 2014 meta-analysis of 16 randomized trials found that probiotics given in the prenatal and postnatal period reduced the risk of AD in the first years of life in both children at high risk of atopic dermatitis and in those from the general population.

What is better than probiotics?
With Viscera-3, transporting butyrate (butyrate is a postbiotic which is superior to probiotic supplements) straight to your colon to fix your digestive bathroom issues is quick and easy. You can enjoy a balance of the gut-brain-hormone axis and as a result, boost immunity and robustness of your physiology.
