Triquetra is a supplement brand founded by Sean Gill and his sister Suzanne. After their own health journeys, they set out to make supplements with clinically studied ingredients at the doses the research actually uses, with every ingredient and dose disclosed on the label.

Every formula follows four commitments: science-first formulations with clinically studied ingredients at efficacious doses, whole-food and plant-based nutrients chosen for bioavailability, fully transparent labels, and innovation in emerging wellness categories.

Yes. After production, finished bottles sit in quarantine for 10 to 14 days while random bottles from each batch are sent to an independent third-party lab. Products have to pass all testing before they ship.

We test ingredient identity and potency, check during production that each formula matches its label claims, test ingredients and finished products for heavy metals against United States Pharmacopeia (USP) standards, and test for microbial contaminants like yeast and mold.

We look for the best-researched form of each nutrient, chosen for absorption and potency, from vetted suppliers. Every supplier has to pass a qualification program built on cGMP standards, and every ingredient is quarantined and tested when it arrives.

The FDA doesn't approve dietary supplements. It regulates them as a category. Our products are made by a cGMP-certified manufacturer and labeled to FDA requirements.

We keep a public Banned Ingredient List of ingredients that never go into our formulas.

Our capsules are plant-based: standard capsules use hypromellose, while our organic capsules use vegetarian organic pullulan.

Every formula is reviewed for allergens and manufacturing compatibility. Allergen and dietary info is listed on each product page, so always check the label if you have an allergy.

Our Science Advisory Board, with expertise in nutrition, functional medicine, performance science, and nutritional biochemistry, helps guide ingredient selection and formulation.

Talk to your healthcare provider before starting any supplement if you're pregnant, nursing, taking medication, or managing a health condition.
