Your diet gives you almost everything. Almost.
A plant-based diet is one of the healthiest choices you can make. But there are 8 nutrients that plants simply don’t provide in meaningful amounts. Not because the diet is flawed. It’s just biology.
✓ B12
✓D3
✓Long-chain omega-3s
✓Iodine
✓K2
✓Zinc
✓Magnesium
✓Selenium
You’re not getting these from broccoli and lentils, no matter how well you eat. And the longer the gap goes unaddressed, the harder it is to catch up.
The fix is simpler than you think.
Only what you need. Nothing you don’t.
Most multis throw in 40-50 ingredients, including ones you already get plenty of from a plant-based diet — vitamin C, iron, folate. That’s not smart formulation. It’s label padding.Essential includes only the 8 nutrients that plant-based eaters specifically tend to under-consume. Each one in its most bioavailable form. Each at a dose that actually matters. That’s it.The star: 470mg+ of algae-based DHA/EPA omega-3s built right in. No other vegan multi gives you that. It’s the reason most people needed a separate omega-3 bottle. Now you don’t.

Ingredients
Ingredients
Vitamin K2 - 50 mcg:
K2 isn't available in plant-based foods except for natto, a Japanese fermented soy product (and it's not in tempeh), so those eating Western diets need to supplement in order to get it.
Vitamin D3 - 50 mcg:
We love nature and spending time outdoors. But we also wear clothing, and most of us work inside during daylight hours. That means our natural ability to soak up the sun's rays is limited, and as a result, many of us — regardless of dietary pattern — might be deficient in Vitamin D.
DHA/EPA Omega-3s - 470 mg:
Vegan food sources of Omega-3s like flax and chia seeds don’t provide two essential types — namely DHA and EPA. Seeds provide ALA Omega-3s, and are an amazing addition to your plate, but most people do not convert ALA into DHA and EPA.
Iodine - 150 mcg:
Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual and developmental disabilities. In plant foods, iodine is found inconsistently and depends on the iodine content of the soil. It’s possible to get enough iodine if you regularly eat seaweed (multiple times a week), or use iodized salt, but this is one essential nutrient that shouldn’t be overlooked whether you’re vegan or not.
Magnesium - 200 mg:
Soil depletion is a major cause of Magnesium deficiency in the overall population, and affects vegans as well as non-vegans.
Selenium - 50 mcg:
Our depleted soil may mean that plant foods, in general, do not contain enough Selenium (and that’s even true for some Brazil nuts).
Zinc - 8 mg:
Legumes and seeds are the best natural sources on a plant-based diets, but vegans who avoid those food groups, as well as those who are worried about its bioavailability can benefit from the addition of Zinc with Complement Essential.
Vitamin B12 - 300 mcg:
Soil bacteria produce Vitamin B12 — which is essential for humans in order to protect neutral health and reduce inflammation. But modern agriculture and other human behaviors decimate these bacterial colonies that produce B12.

Not all multivitamins are built the same.
"I went plant-based and couldn't find a single supplement built for how I actually eat.
I’m Matt Frazier. I founded No Meat Athlete, wrote a New York Times bestselling book, and spent years helping people thrive on plants. But when it came to supplements, everything was designed for omnivores or loaded with stuff I didn’t need. So I built what I wished existed.”

Frequently asked questions. Still not sure?
Find answers to your questions here...What are the nutrition facts?
What are the nutrition facts?

Is Complement Essential vegan?
Yes, Complement Essential is 100% vegan and cruelty-free. (And so are we.) All of the ingredients are sourced from plants, bacteria, minerals or algae.
Does Complement Essential contain soy, nuts, gluten, GMO's or artificial ingredients?
Complement Essential DOES NOT CONTAIN: Soy, nuts, yeast, gluten, MSG, genetically modified organisms, artificial colors or flavors, fish, dairy, eggs or other animal-sourced ingredients.
Who is behind Complement?
We’re a team of nutrition-first individuals with unique health stories and backgrounds. Together, we're on a mission to support anyone looking to live a healthier life by ensuring they have the nutrients and information they need to thrive. Through sourcing the highest quality ingredients and fully transparent production, we leave absolutely nothing on the table when it comes to developing essential, premium plant-based nutrition products.
Why did you make the capsules black?
The unprocessed and unrefined oil used in Complement Essential naturally contains other beneficial compounds including carotenoids, Omega-7, and Chlorophyll — which gives it a dark green color that appears nearly black.
What does Complement Essential taste like?
Being a capsule, Complement Essential should be swallowed without holding it in the mouth, so there shouldn't be a specific taste. To enhance the experience, however, we include a peppermint tab in each pouch that provides a beautiful mint essence to each capsule.
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.
Do I need to take 1 capsule 3 times a day?
Not at all! There shouldn't be any difference between taking all three capsules with a single meal, or spacing them throughout the day.
The one thing that is somewhat important is taking them with a meal that contains at least some amount of fat, as this will help with the absorption of the nutrients.
Can my children take Complement Essential?
We formulated Complement Essential for adults and kids over 12. If you wish to give it to younger children, please consult with your doctor or pediatrician and show them the full ingredients list to determine its suitability and dose. Also, please keep in mind that while most adults and older children have no issues swallowing the capsules, they might be a bit big for younger children. Have a look at Complement spray for an alternative that most of our team members use for their toddlers.
Can I take Complement Essential together with my other supplements or multivitamin?
Complement Essential, together with a whole-food, plant-based diet, will provide you with the nutrients you need to thrive. Formulated for optimal nutrient intake, Complement Essential is safe and non-toxic when taken as directed. If you take another supplement that contains any of the nutrients found in Complement Essential, you may exceed the tolerable upper intake for that nutrient. Speak with your doctor if you have any questions about how Complement Essential works with any other supplements or medications you are taking.
When can I expect my order?
We aim to ship orders within 24 hours of purchase, and all U.S. orders are shipped using 2-day priority mail. In other words, our goal is to get Essential in your hands in just a few days!
