Detailed Description
The main purpose: To investigate if Lactobacillus paracasei GMNL-133(LP), Lactobacillus fermentum GM-090(LF), Lactobacillus paracasei GMNL-133 (LP) with Lactobacillus fermentum GM-090 (LF) combination products could be used for the adjuvant treatment of atopic dermatitis and asthma.
The Secondary Objective: To investigate whether probiotics consumption improve the quality of life and allergic symptoms to different people with Lactobacillus paracasei GMNL-133 (LP), Lactobacillus fermentum GM-090 (LF) and Lactobacillus paracasei GMNL-133(LP) and Lactobacillus fermentum GM-090 (LF) combination products.
