Overview

• Recent NIH findings associate a balanced gut community with lower risks of obesity, type 2 diabetes, cardiovascular disease and neurodegenerative conditions such as Alzheimer’s.
• Researchers describe how ultraprocessed, high-sugar diets, single antibiotic courses, chronic stress, poor sleep and inactivity can disrupt microbial diversity and gut barrier function.
• Specialists recommend gradual restoration through diverse plant intake—about 30 different vegetables per week—plus daily fermented foods, regular exercise, hydration, sound sleep and stress management.
• Clinical evidence supports probiotics for eczema and psoriasis in some trials, with limited or mixed data for acne and rosacea, and typical skin improvements appearing over 8 to 12 weeks.
• Consumer probiotic formulas vary widely by strains, CFU counts and added prebiotics like inulin, with products from brands such as Gloryfeel, N2 Natural Nutrition, AAVALABS and NPRO marketed for digestive wellness.
