Proven Proteins

Grass-fed, traditionally fermented meat sticks with every batch independently tested for contaminants.

Proven Proteins makes fermented meat sticks from grass-fed beef, and beef-and-pork blends, using traditional fermentation rather than chemical curing shortcuts.

Flavors include an original black pepper beef stick plus Berry Blend and Morning Maple beef-and-pork sticks. The company says it has each batch tested by independent labs for contaminants such as glyphosate, mycotoxins and heavy metals, and it publishes the omega-6 to omega-3 ratio of its sticks.

The brand is aimed at people who want a convenient, high-protein snack with transparent sourcing. Products are available individually or in subscription bundles, and the company also runs wholesale and affiliate programs.
