Our Story.

Our Story.

For over 13 years, Matt Frazier, founder of No Meat Athlete and author of the New York Times bestselling book, The Plant-Based Athlete, has built a global movement of active people thriving on a plant-based diet.

But when he partnered with Matt Tullman in 2017 to create Complement, they had just one goal:

To build a nutrient solution optimized specifically for plant-based eaters — one that broke the established path in the industry by filling the gaps in a healthy diet with clean, tested, and transparent ingredients.

Today, Complement's science-backed philosophy has empowered more than 100,000+ plant-focused people to revolutionize the way they complement their diet and lifestyle.

Don’t supplement, Complement.

Introducing the world's first vegan supplements complements designed to deliver only what's missing from a plant-based diet... and nothing else.

We’re taking your already healthy diet, filling in the nutrient gaps, and leaving you with the confidence you need to thrive.

What the experts are saying

As a vegan, I knew that I needed to take vitamin B12, vitamin D, and the Omega3 fatty acids DHA and EPA, so I laboriously took them separately. Enter Complement — all these necessary nutrients in one convenient, virtually tasteless spray. Why didn't somebody think of this before?.


Main Street Vegan Host

Attaining adequate sources of B12, D3, and DHA/EPA is critical to ensuring your plant-based diet is protecting your health for the long run. I'm excited that Complement finally provides a way to get all three of these essential nutrients that's as easy as a few sprays on your favorite vegan dish!


America's Healthy Heart Doc

Finally — a simple, clean, pleasant way to complement a whole foods, plant-powered diet and get the nutrients you need to thrive! I take Complement every day, and so do my twin sons. It’s simple, clean, and effective. No GMOS, and no junk. Just critical nutrients, all combined perfectly, in one place.

I’ve been plant based for the last 5 years. Once I started on the Complement Vitamins, I’ve seen a significant change in my health, energy, hair and nail growth, and overall I just feel good.
Thank you.

Best supplement EVER

I started taking complement months ago, I have noticed a big difference in overall health feeling every day life. I have been vegetarian for over 40 years, I have finally found MY supplement. Thank you

Best Vegan Vitamins

A couple of black pills a day and I get the extra nutrients that I can’t get being a vegetarian.

Complement Essential Liquid

Thoughtful Supplements

I have been pleased with the thought and care that goes into the supplement line, from the packaging to the ingredients. I have also just joined the Insight program - though I have not yet had a chance to check it out - and it also appears to be a deliberate effort to improve lives and satisfy desires to get answers about our health.

Wonderfully recommended!

Several people who love this plant-based vitamin have recommended it to me. I’m very excited to be using it now too!

Great tasting

Easy to fold into routine. Great taste and mixes easily with water.

Complement Core
J C. (Terre Haute, US)

I have used several of the Complement products trying to decide what is best for me. I like that they offer a full range and that they are all very clean. I also like that they are very upfront with what is in them and the 3rd party testing. I just read that there are over 90,000 supplements on the market. It’s a crazy world to navigate and Complement is where I have settled.

So thrilled

I have been dealing some thyroid issues and as a result a lot of hairloss. I've taken the supplements for close to a month and have been very happy with the results

New user happy to have a plant based option

As a vegan, I try but know I don’t always hit my nutritional needs. Although I don’t want to take a variety of supplements the idea of taking one vitamin to help fill in the nutrients I may be missing was a no-brainer. The formula appears very well rounded and I like the third party verification. That helps with piece of mind considering most of the supplement industry is not regulated. I have only been using them for a week or so. I like the idea that with my meal planning and vitamin taking, my nutrient needs are met.

Perfect Vegan Supplement

I love the quality of Complement supplement for whole food plant based eaters. It has everything I want and need in one supplement. When you add up the cost of all the ingredients individually it is a great value - not to mention it is so convenient. I have been taking it for a year and I truly notice a difference. I’m very picky about what I put into my body and who I support with my purchasing power. Complement fits the bill!

Great Product

I love Complement. There are so many different products to choose from to suit your needs! They are also so helpful if you need to change delivery dates or have questions. I feel like I can now take one supplement and be done!

Good Stuff

I really like this stuff!

Merisa R. (Camden, US)
Exactly what a plant-based individual wants!

This is exactly what a plant-based individual wants! I have tried to get all of the micro nutrients into my day by calculating and choosing different foods to match it my needs. Now I can eat the foods I love and focus on my macros. I still utilize my knowledge of foods high in micronutrients to maintain a balanced diet. However, complementing with Complement makes me feel less overwhelmed.

The minty sent doesn’t hurt either!

Best All-in-One Supplement!

This truly is a compliment to my plant-based diet, providing everything I need and nothing I don't in order to meet my nutritional needs! I love the transparency of the company and the ease of taking one product vs 5-10 different products. Would recommend to anyone looking to fill any gaps in their diet!

Convenient vegan multivitamins

I like that all the essential vitamins for vegans are packed in easy-to-swallow gel capsules. Convenient and effective.

Compliments for compliment

Good vitamins with a minty smell. Bought 6 month supply and it came with a black jar to store the vitamins. Happy with them so far!

I was looking for a supplement to make sure I got all of the essential vitamins and minerals while eating a vegan diet. I didn't want a lot of extras and I find that Complement fits the bill!

Boosts energy, and mood.
