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.

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.

Great!

I love this protein powder. Others that I’ve tried in the past make my stomach hurt and taste terrible. This stuff is great-no taste, easily digestible, fine enough grind I can shake it in a blender bottle or add to baked goods for an extra protein boost. Love this stuff-so versatile. I recommend it to everyone! I’ve got 5 additional people hooked on it already and they love it too. Super clean no worries about what is in it! I love it. Try it! You won’t regret it.

How should I use Complement Protein?

We designed Complement Protein to be versatile - meaning you can add it to a smoothie, mix it with plant milk or other drink, or even use it for baking! (Please share whatever you create with it by tagging us on IG @LoveComplement :)

Does it contain any allergens?

Complement Protein is soy-free, gluten-free, and dairy-free! (And obviously, free of any other animal-based ingredients.) It does contain peas and almonds , which some people may be sensitive to.

Is it certified organic?

Complement Protein is made from USDA certified 100% organic ingredients.

Is Complement Protein made from whole foods?

Complement Protein is made from 5 real food ingredients with zero additives or fillers.

How does it taste?

Absolutely no chalky or grainy aftertaste. It's truly the definition of "unflavored!" Complement Protein does NOT contain any flavors, natural or artificial, nor any sweeteners — it is a neutral blend of complete plant protein. We believe that makes it the cleanest, most versatile option — and allows you to mix it with whatever whole food ingredient tastes best to you.

I heard that organic plant protein powders have the highest levels of heavy metals. Is this true?

Heavy Metals are a natural part of our environment and, unfortunately, because they exist in the Earth’s soil, they end up in organic fruits and vegetables. Some recent research seems to indicate that many vegan protein powders contain high levels of heavy metals, like lead, cadmium, and arsenic. That’s one of the reasons we created Complement Protein -- so we could be absolutely sure that it exceeds the stringent California Prop 65 standards, which are up to 1,000 times lower than levels still deemed safe by the FDA. We only create products that we are comfortable giving our young children, so we go beyond even what government entities suggest to ensure safety.

Does Complement Protein ship internationally?

Yes! Complement Protein is available to order in Canada, the EU, Australia, New Zealand and Hong Kong. Let us know if your country is missing from the list, so we can check the shipping costs for you. (And please keep in mind that international orders may incur extra import fees at delivery. This is country-specific, and out of our control. There's very little we can do to assist with packages lost or detained by customs.)

If you have any questions, please email team@lovecomplement.com and we'll be happy to assist you.

What if I change my mind?

You are 100% covered by our 100-day money-back guarantee if you you receive your order and decide you don't like it.

How does the subscription work? And can I change it? 

By choosing to subscribe to Complement Protein, you're locking in a price that's 10% lower than retail - for life! You can choose your delivery frequency when you order (for example, if you get a single bag, you'll probably want it delivered every month, but if you get three, you might want to get your order every three months instead), and adjust it at any time through your dashboard, or by contacting us - we're always happy to help.

There are no minimums or cancellation penalties - you can skip, change or cancel your standing order at any time. Again, this can be done through your dashboard, or by sending us an email.
