Proteinex

What Proteinex does

Proteinex is a U.S.-based manufacturer of concentrated liquid protein supplements, founded in 1998 and operating under Llorens Pharmaceutical International Division, Inc. The company produces two core formulations — Proteinex Core, a clinical-grade hydrolyzed protein delivering 18g of protein per 1 oz serving, and Proteinex Pure, a certified grass-fed collagen variant delivering 15g per 1 oz serving. Its underlying technology centers on enzymatic hydrolysis that breaks collagen into peptides under 3,000 Daltons molecular weight, enabling rapid intestinal absorption without requiring prior digestion. All manufacturing is performed in-house at an FDA-registered, cGMP-compliant, UL-certified facility in Miami, FL, with every batch independently third-party tested.

The company sells directly to consumers through a Shopify-powered e-commerce storefront at proteinex.com, complemented by Amazon marketplace distribution with Buy with Prime. Revenue mechanics combine one-time purchases (priced $19.99-$29.99 for 16-30 oz bottles, with bundles up to $118.96) and subscription/recurring orders managed through Recharge with subscriber-exclusive discounts. The target customer base spans fitness practitioners (gym-goers, HYROX competitors, runners, Pilates/yoga), GLP-1 medication users, busy professionals, medical-nutrition patients, and wellness consumers seeking skin and joint support.

Proteinex has positioned itself as a convenience-first alternative to protein powders, leveraging 25+ years of clinical trust in hospital and rehabilitation settings. Marketing is concentrated on Instagram community content, email, and marketplace presence. The geographic footprint is U.S.-only (plus Puerto Rico), with no disclosed funding rounds and a headcount band of 11-50 employees, indicating a bootstrapped, mature, mid-scale consumer brand rather than a venture-backed growth-stage company.
