The best evidence lies with probiotics supplementation in mothers and infants in preventing development and reducing severity of AD .
Specifically , Lactobacillus rhamnosus GG was effective in long-term prevention of AD development .
γ-Linolenic acid reduced severity of AD .
Supplementation with prebiotics and black currant seed oil ( γ-linolenic acid and ω-3 combination ) was effective in reducing the development of AD .
Certain types of nutrient supplementation are beneficial in preventing AD development and reducing its severity .
OBJECTIVE To identify whether nutrient supplementation with probiotics , prebiotics , formula , or fatty acids prevents the development of  atopic dermatitis ( AD ) or reduces the severity of AD in newborns to children younger than 3 years .
Probiotics and prevention of atopic disease: 4-year follow-up of a randomised placebo-controlled trial
Perinatal administration of the probiotic Lactobacillus rhamnosus strain GG ( ATCC 53103 ) , reduces incidence of atopic eczema in at-risk children during the first 2 years of life ( infancy ) . We have therefore assessed persistence of the potential to prevent atopic eczema at 4 years . Atopic disease was diagnosed on the basis of a question naire and a clinical examination . 14 of 53 children receiving lactobacillus had developed atopic eczema , compared with 25 of 54 receiving placebo  ( relative risk 0.57 , 95 % CI 0.33 - 0.97 ) . Skin prick test reactivity was the same in both groups : ten of 50 children previously given lactobacillus compared with nine of 50 given placebo tested positive . Our results suggest that the preventive effect of lactobacillus GG on atopic eczema extends beyond infancy
