What is the Gut Microbiome? Why is it important?

The gut microbiome is the community of microorganisms living in your gut that plays a critical role in digestion, the immune system, brain function, metabolism, and disease prevention. An imbalanced gut microbiome can lead to a range of health problems. To prevent that, our precision probiotics program is designed to restore balance and promote a healthy gut microbiome. By improving digestive and immune function, precision probiotics can help you feel your best.

Why do I need personalized probiotics more than off-the-shelf ones?

Off-the-shelf probiotics are standardized, meaning they have the same formulation for every bottle and for everyone. However, everyone has a unique and ever-changing microbiome. A personalized and adjustable probiotics program is much more effective. To resolve chronic symptoms that are related to microbiome imbalances, a probiotics formulation like ours that updates over time is needed.

How does the Precision Probiotics Program help with addressing gut health?

Our Precision Probiotics Program uses microbiome biotechnology, state-of-the-art sequencing, and machine learning to personalize probiotic formulations specifically to your needs. Our program also includes mobile-based lifestyle recommendations and virtual coaching to help you make the most of your regimen. We prioritize precision, innovation, and science-based solutions to provide the best possible results for our customers. By combining highly personalized probiotics with lifestyle changes tailored to your specific needs, our program can greatly improve your gut health and overall wellbeing.

Who is this for? How does our program help?

Our program is designed for individuals who want to improve their overall health and wellbeing by optimizing their gut microbiome. It can help you enhance your immune system and brain health, relieve digestive issues like constipation, diarrhea, bloating, and gut discomfort, decrease abnormal inflammatory responses like skin irritations, and increase the effectiveness of antibodies and vaccines. Whether you have chronic gut health conditions or simply want to feel your best, our personalized probiotics program can help you achieve your goals.

What are probiotics and what are they made of?

Probiotics are beneficial microorganisms made up of bacteria and yeasts that are taken in to improve your gut microbiome's function and overall balance. Our body's microbiome is vast and complex, so our precise probiotics program carefully picks such beneficial probiotics tailored to your gut conditions.

How are quality standards controlled for our probiotics?

Our personalized probiotics are produced through GMP standards which ensures the quality and consistency in the production processes.

How does the Precision Probiotics Program work? / What are the steps of the program?

After subscribing to the program, the logistic company will send out to you a gut test kit within 7 days with which you will provide the stool sample. Afterwards, the logistics company will collect the sample within 3 days upon request and send it directly to our partnering laboratory. The laboratory will build a full genome library through extracting the sample's DNA then sequence it. After 4 to 6 weeks, the laboratory issues a report to us where we will further analyze with our artificial intelligence model and provide you with a detailed report, personalized probiotics, and 1-on-1 consultation with our nutritionist.
