Unseen Bio
Read full descriptionHide full description
The Unseen Bio app provides an easy and clear overview of your microbiome results, issued after you've taken the consumer test. With our microbiome test, you get a current snapshot of your gut health and guidance on how to improve it. In the app, you’ll find results on: • Your Biodiversity Score – this score provides you with insight into how many unique species of bacteria are in your gut and the diversity that contributes to a healthy microbiome. • Beneficial, Non-Beneficial, and Harmful Bacteria – these results describe which and how many of these bacteria are present in your gut and which foods feed them. • Fungi – describes which and how many fungi are in your gut and which foods feed them. • Your Microbiome Age – indicates how old your microbiome appears compared to your actual age. • Your Diet Score – this result is based on a comparison between your dietary records and the ideal microbiome diet. We also provide recommendations on which foods you should eat more or less of. • Your Physical Activity Score – shows how your activity level compares with our healthy reference group. • Lifestyle Inspiration – a guide to improving gut health through lifestyle changes. • Your Probiotics Levels – describes which types of these bacteria are present in your gut and which supplements contain those you may lack. The results are visualized through easy-to-understand interactive graphs and color scales, always comparing your results to a healthy reference group. App features: • Dive deeper into each bacterium and fungus found in your microbiome, learn about their behavior, and compare quantities with our other reference groups. • If you've taken multiple tests, you can compare your results with previous ones to track your progress. • Share your results with a healthcare professional or with a friend to compare outcomes. • If you haven’t taken a test yet, you can answer questionnaires that, along with the test, help us ensure the quality of your results. Optimize your gut health—take a microbiome test. If you have any questions, please contact us at: support@unseenbio.com.
