Promix Nutrition is a clean-label sports nutrition brand founded in 2011 by Albert Matheny—an exercise physiologist, registered dietitian, and former collegiate triathlete—who created the company after being unable to find products to meet his high standards for ingredient quality and science‑backed performance.

Headquartered in Gainesville, Florida, Promix employs a team of exercise physiologists and dietitians to develop formulas rigorously tested by elite and everyday athletes under intense conditions.

Promix distinguishes itself with its “No Artificial Anything™” philosophy: no gums, fillers, hormones, glyphosate, GMOs, soy, gluten, antibiotics, or artificial flavors. They produce powders, bars, pre-workout mixes, electrolytes, liver support, creatine, collagen, and more—all in GMP‑certified facilities with batch testing for purity. The brand also commits 1% of sales to environmental causes via 1% for the Planet.

• Vitamins & Supplements: While there are plenty of “standard” supplements, such as Iron, Glutamine, and Creatine, there are also more atypical products such as Raw Liver Capsules, Debloat (a pre- and probiotic), and Bone Marrow Capsules.

• Protein Bars: Whey Protein Bars and Vegan Protein Bars are designed to support recovery and curb cravings.
