What Purest Colloids does

Purest Colloids, Inc. is a privately held, founder-owned dietary supplement manufacturer incorporated in New Jersey and headquartered at 600 Highland Drive, Suite 602, Westampton, NJ. Founded in the late 1990s by Francis S. Key, who also serves as CEO and principal scientist, the company designs and manufactures nanoparticle metal colloidal products under its MesoColloid brand, including MesoSilver, MesoGold, MesoCopper, MesoPlatinum, MesoIridium, MesoZinc, MesoPalladium, and MesoSilica. These products are produced via the proprietary "Mesoprocess," which generates mesoparticles ranging from sub-nanometer to 10 nanometers in diameter dispersed in ultra-pure deionized water, with the company claiming the highest particle surface area tested among nanoparticle silver products.

The company holds two granted U.S. patents (7,122,370 and 7,229,818) covering a buffered alginate-gel delivery system used to protect live probiotic organisms and digestive enzymes through stomach acid, alongside registered trademarks (Mesocolloid, Mesoprocess) and several patent-pending technologies including T.I.P. packaging, LactoStim prebiotic stimulation, EnzaStim fat-emulsifier, and Deep Release acid-proof gel. Beyond the mesocolloid core, the catalog includes two probiotic products (TruFlora and Theralac), a multi-enzyme supplement (Enzalase), a soluble fiber supplement (TruFiber), topical variants (creams, antifungal/antibacterial spray), a hot tub water-treatment SKU, bulk packaging tiers (1 gallon, 5-gallon carboys), combination packs, and a small set of third-party supplements (Vitamin C drink mix, raw brown rice protein powder) and a complementary nebulizer device.

Purest Colloids operates a direct-to-consumer go-to-market, with all revenue derived from sales through its owned Netsuite e-commerce storefront (shop.purestcolloids.com) and phone orders taken between 8:00 a.m. and 4:30 p.m. EST, plus a 24-hour order line for after-hours placement. Products are sold with a 120-day money-back guarantee, volume discounts at 4–9 and 10+ units, and shipped both domestically and internationally via UPS/USPS, with stated restrictions on shipments to Africa, Mexico, Brazil, and Iceland. Marketing relies on organic search traffic, an extensive educational Learning Center, customer testimonials, and a batch-number verification system tied to third-party lab concentration reports. The company has no disclosed funding rounds, no institutional investors, and operates with a headcount of 1–10 employees; it claims exclusive worldwide production rights for Mesocolloids and maintains an ongoing R&D affiliation with Colloidal Science Laboratory, Inc. (CSL), founded by the same principal scientist.
