Pure Encapsulations is a respected American supplement brand founded in 1991 with a mission to offer pure, research-based nutrition. Established in a restored New England watermill, the company has grown into a leader in hypoallergenic supplement production by combining rigorous science, clean sourcing, and pharmaceutical-grade manufacturing.
Manufacturing Excellence and Rigorous Quality Control
All Pure Encapsulations supplements are manufactured in-house at their state-of-the-art facility in Sudbury, Massachusetts. Production occurs in temperature-, humidity- and dust-controlled environments to ensure consistency and safety. Equipment—such as mills, blenders, and encapsulating machines—is sterilized before every batch. Trained operators inspect capsules every 15 to 20 minutes, while quality assurance specialists conduct checks every 60 to 90 minutes. Finished products undergo stability testing to preserve potency throughout shelf life. This tightly regulated process aligns with NSF-GMP standards in the U.S. and GMP certification in Canada, and exceeds U.S. Pharmacopeia benchmarks.
Clean, Premium Ingredient Sourcing
Pure Encapsulations sources its raw materials from leading global suppliers in the U.S., France, Japan, Switzerland, Germany, and Italy. Ingredient selection is strictly based on purity and bioavailability. Every batch of raw material is tested for identity, potency, microbial contamination, heavy metals, solvent residues, pesticide compounds (for herbs), and toxins (for oils). All ingredients are verified GMO-free through supplier statements or direct PCR testing. Many products carry Gluten-Free Certification Organization (GFCO) certification. The label lists every ingredient, including elemental weights, standardized herbal extracts, and allergen declarations.
Science-Driven Formulation and Clinical Research
Formulations are developed in collaboration with PhDs, clinical nutritionists, and medical advisors. Only ingredients with proven clinical value go into production. Over 30 product-specific clinical trials support Pure Encapsulations’ efficacy in areas such as immunity, cognitive support, metabolic health, and inflammation. Awards from the Nutrition Business Journal highlight the brand’s investment in scientific innovation and industry leadership.
Hypoallergenic Commitment and Transparency
Products are free from major allergens and unnecessary additives—including gluten, dairy, soy, peanuts, magnesium stearate, artificial colours, flavours, sweeteners, and fillers. The company’s allergen protocols ensure no cross-contamination. All labels offer full ingredient disclosure. Third-party certified labs validate finished products for purity and potency, adding an extra verification layer beyond internal testing.
