Do Plant-Based Eaters
Need A Multi (When Their Food is Already Healthy)?
As a plant-based eater, you’re already following the healthiest and most responsible diet on earth, enjoying an abundance of most nutrients with every meal and supporting foundational long-term health. But, if you rely on whole foods alone, chances are you’re still missing a few key nutrients — and there’s (almost) nothing you can do about it.
A lack of complete nutrition can, at best, make you function at less than your peak. At worst, it can lead to serious health problems down the line.
But don’t take our word for it…
Look at the Statistics
So what’s going on here? Why can’t plant-based eating alone cover all bases? Here are 3 good reasons:
Your food is weaker than it used to be.
A United Nations’ study reports that 33% of the world’s soil resources are degraded — largely due to industrial agriculture. Poor soil quality negatively impacts the nutrition in our food, as well as its production and sustainability.
You eat the same stuff.
Think about how many of the same foods and meals you eat week after week. A review in Molecular Metabolism revealed that 75% of the world’s food comes from only 12 plants and five animal species. That’s not enough variety to ensure optimal nutrition.
Your body can’t absorb some nutrients, and can’t access others.
Plant-based sources of vitamin B12 and Vitamin D aren’t as bioavailable as their animal counterparts, and omega-3 fatty acids like DHA and EPA are nearly impossible to obtain in adequate amounts from a standard plant-based diet.
So what’s the solution?
In some cases, eating more of specific foods rich in the hard-to-get nutrients might help, since that would add more of those nutrients into your diet. But that's not always practical (you'd have to be munching seaweed all day every day to get enough DHA and EPA omega-3s, for example — and then you'd overdose on sodium and iodine).
You could also add individual supplements to your diet to fill in the gaps, but then you’d have to micromanage each one to make sure you’re getting enough, and in the right amounts. Plus, the cost of those individual bottles would add up quickly.
So how about taking a typical multivitamin?
Well, now you’re overcorrecting the problem, paying for a bunch of nutrients you’re already getting from your plant-based diet. You’ll end up peeing out the excess. Talk about money down the drain… And you’re still not getting those omega-3s.
Try Complement Essential (and Feel the Difference)
Now there’s an all-in-one multinutrient supplement that contains only the essential nutrition proven to be lacking in most plant-based diets, and nothing extra.
Complement Essential is:
- VITAMIN B12
- VITAMIN D3
- VITAMIN K2
- IODINE
- MAGNESIUM
- SELENIUM
- ZINC
- DHA / EPA OMEGA-3s
It’s the ultimate complement to healthy, plant-based eating, providing an insurance policy for optimal nutrition.

Each vegan capsule is peppermint scented, offering a refreshing smell that makes it easy and pleasant to enjoy. No more chalky pills that could choke a horse — and no more gagging on fishy smelling burps!
What can Complement Essential do for the planet?
Essential comes in a biodegradable pouch, and your first order comes with a refillable glass jar, so you can store your Essential supply — or anything else you choose — long-term in an eco-friendly container.
And the pouch? It's 100% biodegradable and compostable. Add it to your food waste or compost bin, so it puts something back into the earth for what it took out of it. It’s made from plant fibers (bio-resins and wood cellulose), so it will break down on its own within 12 months.

A Plant-Based Supplement, Rooted
In Trust
Complement Essential is formulated, produced, and third-party tested right here in the USA. Unlike most vitamin brands “white-labeling” products produced by another company, at Complement, we do it all ourselves. From sourcing to shipping, we’re with you every step of the way.
Ingredients highlights.
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.
Benefits:
Helps with heart and bone health.*
The smart part:
Vitamin K2 is the natural partner to Vitamin D3, acting as a regulator for increased calcium uptake and promoting good bone health. Complement Essential™ includes 50mcg of Vitamin K2 as menaquinone-7 (the natural and most absorbable form of K2) per daily serving, sourced from bacteria.
Sourced from:
USA 
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
Benefits:
Supports bone health and immunity.*
The smart part:
While many vegan multivitamins contain the less effective D2 form, Complement Essential™ provides 2,000 IU of the only truly vegan D3 available (Vitashine, sourced from lichen) per daily serving.
Sourced from:
UK 
DHA/EPA OMEGA-3S
450 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.
Benefits:
Supports brain and cholesterol health, nervous system regulation, and improved energy levels.*
The smart part:
Complement Essential includes 300mg of DHA and 150mg of EPA per daily serving, sustainably sourced from algae grown under controlled conditions and tested for purity.
Sourced from:
USA
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.
Benefits:
Supports healthy thyroid function, which regulates the metabolism.*
The smart part:
Complement Essential includes 150mcg of iodine per daily serving, sustainably sourced from kelp.
Sourced from:
CANADA 
MAGNESIUM
200 mg
Soil depletion is a major cause of Magnesium deficiency in the overall population, and affects vegans as well as non-vegans.
Benefits:
Supports your metabolism, energy levels, mood, and heart health.*
The smart part:
Magnesium works to increase the efficiency of Iodine and helps regulate the thyroid function. Complement Essential includes 200mcg of Magnesium per daily serving, in the form of magnesium citrate, the form that’s easiest absorbed by the body.
Sourced from:
USA
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).
Benefits:
Supports brain health, mood changes, and heart health.*
The smart part:
Similar to Magnesium, Selenium works in tandem with Iodine to promote healthy thyroid function and metabolism, as well as the removal of heavy metals from the body. Complement Essential includes 50mcg of Selenium per daily serving, in the naturally occuring, plant-sourced form of L-selenomethionine.
Sourced from:
INDIA 
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.
Benefits:
Supports the skin and nails, healthy growth and eyesight, wound healing, and a well-functioning immune system.*
The smart part:
Complement Essential includes 8mg of Zinc per daily serving, a zinc picolinate, the form easiest for the body to absorb and utilize.
Sourced from:
INDIA
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.
Benefits:
Supports red blood cell formation, neurological function, & DNA synthesis.*
The smart part:
Complement Essential contains 300mcg of B12 per daily serving, combining methylcobalamin and adenosylcobalamin, the easiest forms for the body to absorb and use.
Sourced from:
China

WHY DARK ALGAE OIL IS THE BEST SOURCE OF OMEGA-3S
Omega-3 fatty acids — including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) — are critical for the proper structure and function of cell membranes. They help keep your brain, heart, and immune system healthy†. Most people don’t get enough omega-3s, especially plant-based eaters, and they mistakenly believe that fish and fish oil are the only sources.
Good thing that’s not true, because there aren’t enough fish in the ocean to provide the world’s population with the DHA and EPA it needs.
Health organizations recommend getting 250–2,000mg of DHA and EPA, combined, daily for optimal health, but scientists have calculated that, based on an intake of just 500mg daily, it would take...
1.2 million more tons of DHA and EPA than what is currently available to serve the world’s population — and fish only supply 15% of the global demand.
But hold on a minute…
Fish get their omega-3s by eating algae, so why not just go straight to the source? Algae grows quickly and doesn’t contribute to overfishing, so it’s more sustainable than harvesting fish. Algae oil is a potent source of omega-3s, and research has shown that algae oil production puts less strain on the ecosystem than that of fish oil — and will continue to, even with increased demand.
The unprocessed, unrefined algae oil used in Complement Essential contains additional beneficial compounds, such as carotenoids, omega-7 fats, and chlorophyll, which gives it a dark green color that appears nearly black.

Fully transparent production.
Complement Essential 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.
Third-party tested.
This means that every ingredient and dosage on the back of the bag is verified by an independent lab. And just as important, the ingredients are tested for things like pesticides, E Coli, heavy metals, and salmonella.
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.
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
Our products are doubly protected by being produced in a certified facility, and tested for yeast and mold, and possible bacterial presence, such as Salmonella, E.coli and other coliforms.
100% Happy
We stand behind our products 100%. If you're not happy with the results, taste, or experience, we'll fix it.
100-Day Guarantee
You have a full 100 days after receiving your product to try it out and see if it's the right fit for you.
100% Money-Back
And if you don't love it within the first 100 days, we'll issue a full refund. No questions asked. No fine print. That's the Complement guarantee.

Frequently asked questions. Still not sure? Find answers to your questions here...
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 an all-vegan team on a mission to support the health of the vegan movement, by protecting the health of individual vegans with the nutrients 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!
