Great product

Definitely enjoying COMPLEMENT

Good... It's good.

Not at all sweet, so sometimes you need to add sumpin'. I do like that it melts quickly into plant milk, so it's good for hot chocolate! I love that it is clean ingredients and it doesn't have a weird taste, so I'll probably keep buying it. It's definitely the best I have tried. I love that it is micro-fine and not gritty.

Great customer service and protein powder

I recently order 2 bags of protein powder. Upon receiving the package one of the bags had a tear in it. Complement was on top of it when I notified them of the issue and within no time I had my replacement. Their chocolate flavored protein powder has a great taste and I look forward to ordering more.

Love it!

I just switched to Complement this past summer after using another protein powder for years and I love it! I also love that they have it tested by a third party to ensure the product is safe and high quality.

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, 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.

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

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.

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.
