Zinzino’s Groundbreaking Gut Health Test is Backed by Science
The easy, at-home finger-prick test delivers results grounded in established research on tryptophan metabolism and its connections to gut and metabolic health
Jupiter, FL December, 2025 — Zinzino, the renowned health and wellness company, is leading the way in personalized at-home testing with its groundbreaking Gut Health Test, completed with a simple finger prick. This innovative approach goes beyond the traditional stool testing, revealing not only which microbes are present but also whether they are active, what they produce, and how the body responds to them. The result is a deeper understanding of the gut-body connection and how diet and lifestyle influence it, and how to support a healthier, more resilient body from the inside out.
“This test provides so much more information than the traditional gut microbiome test, but how the body processes tryptophan, an essential amino acid found in food, and how this affects gut and metabolic health,” says Dr. Martina Torrissen, Zinzino’s Research & Development Specialist. “By measuring these signals in the blood, we can give clear, science-based guidance on how to eat and how to live to support a healthier gut. It’s so important for wellness, since the gut is a powerful control center for the body, affecting metabolism, mood, immune system, and so much more.”
The Science
Zinzino’s Gut Health Test is based on metabolomics, measuring the signals gut bacteria leave behind in the blood to gain insights into how the gut interacts with the body’s own processes in nutrient and energy metabolism. The markers measured (IPA, KYN, TRP, and their ratios) are widely studied in peer-reviewed science as indicators of microbial activity and immune-linked metabolism. All analyses are performed by Vitas AS, an independent chemical analysis laboratory and world leader in dried blood spot (DBS) testing.
Each personalised report provides detailed results that include customized recommendations with science-based guidance on diet and lifestyle to help improve and maintain results over time, as well as a follow-up test after 120 days to track the body’s response to diet and lifestyle adjustments.
