Priority One has been run by the same family since 1988, guided by a mission statement that reads "Never trade your morals for your goals." Its formulas are produced by sister company First Priority Manufacturing in an NSF-certified CGMP facility that is registered with the FDA, certified by the State of Washington for dietary supplement manufacturing and approved in more than ten countries. Much of the quality work happens in-house. Incoming raw materials are quarantined until they pass identity, purity and potency testing, multistage protocols built on USP standards follow each batch from production through bottling, and a selected third-party ISO-certified laboratory adds an outside check. A full-disclosure labeling policy means raw materials are rejected when suppliers will not reveal what was used to process them, and botanicals are monitored to confirm they are never sterilized with radiation. The catalog leans toward practitioner-style formulas, from vitamins in active forms such as Quatrefolic folate to grass-fed, freeze-dried glandular concentrates and digestive blends, with many products in vegetarian capsules and dietary details listed for each one.
All Priority One supplements are made in the United States by its sister company, First Priority Manufacturing. The facility is NSF-certified, operates under FDA 21 CFR Part 111 Good Manufacturing Practices, and is registered with the FDA.
Yes. Priority One is NSF/ANSI 455-2 certified. Testing combines an in-house laboratory using NSF-designed protocols based on USP standards with a selected third-party ISO-certified laboratory. The program includes checks for heavy metals, microbial contaminants and potency.
Many Priority One products use vegetarian capsules. Products that contain glandular concentrates are not suitable for vegetarians or vegans. For capsule type, common allergens and dietary suitability, consult the label and other product information.
Priority One uses grass-fed, freeze-dried glandular concentrates sourced from animals raised without hormones or antibiotics.
Where appropriate, Priority One uses Quatrefolic® (5-methyltetrahydrofolate glucosamine salt), an active form of folate, instead of synthetic folic acid.
