    Biography

    About Dr. Grace Liu

    Dr. Grace Liu, PharmD, is a clinical pharmacist and IFM trained functional medicine practitioner (AFMCP) who founded The Gut Institute, an education and formulation practice focused entirely on the gut microbiome. She is widely known in the functional and ancestral health community as The Gut Goddess.

    Her clinical work centers on rebuilding the microbiome using functional lab testing, nutrigenomic tools, resistant starch and targeted probiotics. In her own words the goal is reversing modern gut dysbiosis and disease, rather than managing symptoms one prescription at a time. The Gut Institute states its motto simply: bugs over drugs.

    The conditions she works with are the ones that rarely resolve with a single intervention: SIBO, dysbiosis, food reactivity, acne and skin disorders, autoimmunity, mold illness, co-infections and persistent brain fog. Her consulting clientele has included athletes and coaches from the paleo and combat sports world, among them Robb Wolf, Kyle Kingsbury, Noad Lahat and Miriam Nakamoto.

    She is a frequent conference speaker and podcast guest, with appearances at Paleo f(x) and LowCarbUSA and on Bulletproof Radio, The Paleo Solution, Rational Wellness, Endurance Planet and Biohacker Babes. In 2018 she published a practitioner facing guide, 7 Steps To Heal SIBO. Her long running writing includes the Animal Pharm blog and, more recently, gutgoddess.blog.

    Her bridge to peptide medicine is direct. The Gut Institute publishes a program titled Beyond Probiotics: The Emerging Science of Peptides and the Gut Microbiome, which examines how peptide signalling and the microbiome intersect. That intersection is exactly where her teaching contribution at Peptide University sits: gut terrain as a precondition for peptide response.

    Faculty

    Grace at Peptide University

    Dr. Grace Liu teaches gut health and peptide therapy at Peptide University, connecting microbiome testing to the peptide protocols practitioners use for barrier repair and GI recovery.

    Her teaching covers the sequence most clinicians get wrong: interpreting stool and organic-acid testing first, then selecting peptides, dosing them for gut-lining and immune support, and re-testing to confirm the response.

    Practitioners train with Dr. Liu through Peptide University's live clinical classes and Inner Circle membership, alongside the Clinical Peptide Therapy Certification curriculum.

    Clinical Focus at Peptide University

    Microbiome Restoration

    Rebuilding a depleted or disordered microbiome with targeted strains, prebiotic substrate and sequencing informed decisions rather than broad spectrum guesswork.

    SIBO and Dysbiosis

    Assessing small intestinal bacterial overgrowth and dysbiosis, then staging treatment so motility, terrain and reinoculation are addressed in the right order.

    Resistant Starch and Nutrition

    Using resistant starch, fermentable fibre and food based strategy to feed the strains a patient actually needs, with tolerance built gradually.

    Functional Testing and Nutrigenomics

    Reading stool, organic acid and genomic data together so the protocol matches the patient's biology rather than a generic gut healing template.

    Functional stool, breath and nutrigenomic testing sit underneath every protocol she teaches.
