Defining the Category
Digestive supplements encompass a broad range of products designed to support gastrointestinal health, improve digestion, and maintain gut microbiome balance. The category includes:
Core Product Types:
Probiotics - Live beneficial bacteria (Lactobacillus, Bifidobacterium strains)

Digestive Enzymes - Amylase, protease, lipase for breaking down food
Fiber Supplements - Psyllium, inulin, acacia fiber for regularity

Market Landscape & History
Evolution Timeline:
Pre-2000s: Digestive supplements were primarily basic fiber products and simple acidophilus probiotics sold mainly in health food stores.

2010-2020: The "gut-brain axis" research explosion transformed the category. Microbiome testing became available to consumers. Premium probiotics with specific CFU counts and strain documentation emerged.
2020-2025: The category matured with science-backed formulations, subscription models, and personalized nutrition. COVID-19 heightened focus on immunity and gut health connections.
Current Market Position:
The digestive supplements market has transformed from a niche wellness category into a mainstream health priority. The market is projected to grow from $19.3 billion in 2025 to $34.5 billion by 2035, driven by increasing consumer interest in gut health, preventive medicine, and rising rates of digestive ailments such as bloating, acid reflux, and irritable bowel syndrome.
