A powerful plant-based protein to fit your healthy lifestyle.

seeds, almond and more

Proper nutrition always starts with a diverse whole food diet, filled with protein-rich beans, legumes, nuts, and seeds. But depending on your body, goals, and lifestyle, meeting your protein needs can feel difficult.

That’s why at Complement, we created a clean, diverse, and delicious protein powder optimized to help you reach your health goals. Through an unflavored formula, Complement Protein provides a complete amino acid profile, smooth and non-chalky taste, and transparent ingredients.

Here’s what makes us different...

Transparent
ingredients for peace
of mind.

You deserve to know exactly how much of each ingredient is in your protein powder. Instead of hiding our formula behind a “proprietary” blend, the entire formula is printed right on the front of the bag.

Ingredients highlights.

ALMOND

almond 12%

Almonds are known to support blood and heart health through a variety of powerful vitamins, minerals, and macronutrients.*

CHIA SEED

chia seed 6%

Chia seeds have a long history as a health food, and are known as an incredible source of healthy fats and protein.

PUMPKIN SEED

pumpkin seed 14%

Pumpkin seeds are rich in omega-6s, phosphorus, manganese, magnesium, and iron, and support prostate, bladder, and blood health.*

SUNFLOWER SEED

sunflower seed 11%

Yellow peas are a common protein powder ingredient because they pack a big punch while being easy on the digestive track while still supporting your heart and blood health.*

5 real food ingredients and

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.

icon of potency
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.

icon of cross metal
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

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.

"I love that Complement Protein has just 5 whole food ingredients. No isolates, no fillers, no sweeteners, no additives. I always direct people to Complement because it's made of simple whole foods – plus it's organic and rigorously tested for heavy metals and in a biodegradable bag. My smoothies, pancakes and cookies always get a dose of this good stuff."

Frequently asked questions. Still not sure? Find answers to your questions here...

What are the nutrition facts?

When can I expect my order?

Complement Protein is in stock, and you can expect your order 3-7 business days after placing it (longer for international orders, obviously).

Who actually makes this?

Learn more about our (all-vegan) team here!

What's the serving size and how much protein does it contain?

One serving of Complement Protein is 22 grams (3 tbsp), and contains 15 grams of complete plant protein.

What is the full nutritional profile? How much Carbs or Fat?

Below is the confirmed Nutrition Facts panel for Complement Protein.

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?

YES! All the individual ingredients are fully organic and we're happy to announce that we were able to complete the organic certification for the Complement Protein in time for the first batch as well!

Is Complement Protein made from whole foods?

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

How does it taste?

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.

I use both the vitamins and protein powder. Love them both. I only wish the protein powder had a vanilla flavor to it.

Truly clean protein!

I love using Complement in my post-workout smoothie. It’s so important for building muscles to have protein each morning and Complement makes it easy to make sure I get enough! It tastes great and the ingredient list is truly the cleanest I’ve ever seen. Highly recommend!
