What do studies say about Mikrobiom Labor?

Scientific evidence on microbiome lab tests is mixed. While research confirms that the gut microbiome influences metabolism, immunity, and even mental health, most commercial tests lack robust validation. Studies show that microbiome composition is highly variable, influenced by diet, lifestyle, and environment, and can shift rapidly. A single test provides only a snapshot with limited clinical utility. Many companies rely on small or population-specific reference databases, making individual results difficult to interpret. There are no standardized cutoffs for a 'healthy' microbiome. The German Society for Gastroenterology recommends microbiome testing only within controlled studies. Consumers should be cautious of personalized diet or supplement advice based solely on such tests. The evidence is currently insufficient to guide specific therapies. Microbiome labs can be useful research tools but are not ready for routine clinical use. Always consult a doctor before making health changes based on test results.
