Third-party tested for heavy metals.

Complement Protein goes through a rigorous inspection process that includes third-party testing.

We want you to be certain that you are getting the highest quality nutrients, free from pollutants, heavy metals, and harmful pathogens — not to mention common allergens and artificial sweeteners, colors and flavors. That’s why every batch undergoes a rigorous series of tests to confirm that it contains all that it should - and nothing that it shouldn’t.

And we mean rigorous! We do as many as 19 different tests to ensure potency and safety. All this is done in pharmaceutical-grade facilities that are FDA Registered, and operate under cGMP standards.

Potency

We verify that all active ingredients on the label are present in the right amounts. But we're not satisfied with just meeting those - to ensure potency over time does not diminish, we aim for 10-20% over what the label states.

Heavy Metals

We take soil and water pollution seriously, especially since we design our products to help your body fight against it. Therefore, each batch gets tested for Arsenic, Cadmium, Lead and Mercury.

Pathogens

Our products are doubly protected by being produced in a certified facility, and tested for yeast and mold, and possible bacterial presence, such as Salmonella, E.coli and other coliforms.

Unflavored for complete versatility.

Let’s face it, most protein powders are chalky, clumpy, and off putting. Instead of trying to mask those nasty aftertastes with weird flavoring, we solved the issue by removing filler ingredients and gums to clear a clean, unflavored formula made up entirely of plant-based proteins.

Our unflavored formula means you can mix, bake, or blend Complement Protein into just about anything — including pancakes, smoothies, brownies, or even sauces.
