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.

The best tasting vanilla protein.

Let’s face it, most protein powders are chalky, clumpy, and off putting. Complement’s Vanilla Protein is anything but. Flavored with organic vanilla powder and lightly sweetened with organic fruit extract, this is the perfect powder to blend, shake, or bake into your favorite liquids and foods.

Frequently asked questions. Still not sure?

Find answers to your questions here...What are the nutrition facts?

What are the nutrition facts?

Due to ongoing testing, we don't have the nutrition facts finalized yet.

But while we continue that testing on the Vanilla Protein formula, one thing remains certain: every ingredient will meet our uncompromising standards for quality and purity.

Vanilla Protein will be free from artificial flavors, fillers, or anything that doesn’t align with our commitment to clean, plant-based ingredients. Each batch will undergo rigorous third-party testing (with those results posted publicly) to ensure it delivers the premium quality you expect from Complement.

We’ll share the final formula as soon as it’s complete. In the meantime, if you have any concerns after the formula is set, we’ll happily issue a full refund.

Thank you for your trust as we craft what we're confident will be the best vanilla protein on the market.

Note, while we're not ready to share the facts yet, they'll look a lot like our Chocolate Protein.

When can I expect my PRESALE order?

As soon as possible! We're working as quickly as we can to finalize the formula and send Vanilla Protein into full production. Our best estimate right now is mid to late April, but we'll share updates every step of the way.

By preordering now, you're not only helping production happen, but you're also locking in the lowest price you'll ever see on Vanilla Protein.

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.

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 @Complement :)

Does it contain any allergens?

Complement Protein is soy-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 Complement Protein made from whole foods?

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

What is the suggested use?

For adults and children over 12, take 3 vegan capsules daily, preferably with a meal. Store in a cool, dark place. Please recycle the glass bottle after use.

How does it taste?

Absolutely no chalky or grainy aftertaste.

Complement Vanilla Protein has a subtle hint of vanilla and sweetness without overpowering your palate with fake sweeteners or flavors.

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 plant-based 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 strictest standards. We only create products that we are comfortable giving our young children, so we go beyond even
what government entities suggest to ensure safety.
