Never worry about the hard-to-get nutrients on a plant-based diet again.

We can all agree the plant-based diet is a nutrient powerhouse, and with our plates filled with vitamin- and mineral-rich foods, we don't need everything that comes in a standard multivitamin.

But the latest research shows there are a few essential nutrients missing from most plant-based diets — Vitamins B12, K2, and D3, and DHA + EPA Omega 3s — plus a handful of other hard-to-get minerals like zinc, iodine, magnesium, and selenium.*

Complement Essential provides the eight critical nutrients missing from a plant-based diet, in a liquid formula optimized for your entire family.  

 

Increases Energy*

Methylcobalamin and adenosylcobalamin forms of B12 are combined in Complement Essential to support energy levels.*

 

Optimize Brain Health*

DHA+EPA Omega-3 fatty acids are critical for proper brain development and function, no matter your age.*

 

Sharper Focus*

Omega-3s and B12 can contribute to overall brain health, improving memory and focus.*

 

Heart Health*

DHA+EPA, K2, magnesium and D3 all work together to support a healthy cardiovascular system.*

 

Enhance Immunity*

Vitamin D, zinc, and selenium have all been shown to help boost immunity.*

Stronger Bones*

Vitamin D3 assists in calcium absorptions and works in parallel with K2 to maximize usability in your bones.*

 

Family Friendly

Complement Essential's liquid formula means the entire family can enjoy the same nutrients from a single bottle.

The Essential formula.

 

Premium plant-based nutrition.

The Big 4

Complement Essential is centered around the four critical nutrients even well-designed plant-based diets often lack — B12, D3, K2, and long-chain Omega-3s DHA and EPA.

The Other Essentials

Based on the prevailing science, we included the other essential nutrients that aren't found abundantly in, or aren't adequately absorbed from, plant foods: iodine, magnesium, selenium and zinc.

The Smart Parts

The formula isn't just about getting these vitamins and minerals independently — it's about what they do together. The nutrients truly complement each other, to improve absorption rates and benefits to your body.

Know your nutrients.

 

Not all nutrients are created equal. We offer full transparency from source to bottle, so you know you're only getting the best.

 

Complement Essential liquid is formulated, produced, and third-party tested right here in the USA. When it comes to sourcing the highest quality ingredients, we searched around the globe to find the best, all-natural nutrients available.

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! Everything from hand inspection of each capsule to as many as 19 different tests to ensure potency and safety. All this 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 bottle 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.

What does Complement Essential liquid taste like?

Complement Essential is a nice blend of sweet and citrus. Think perfectly ripened clementine (one of our favorite fruits).

What is the suggested use?

The Complement Essential liquid formula is perfect for the whole family. Here are the recommended daily doses:

Ages 1-3: 1/2 teaspoon (2.5ml)
Ages 4-12: 1 pump (4ml)
Ages 12 and over: full dose (2 pumps/8ml)

How can take my daily dose?

The beauty of a liquid formula is its versatility. Take Essential from a spoon, directly from the bottle, or mixed into a drink or smoothie.

Can my children take Complement Essential liquid?

We formulated Complement Essential for adults and kids over 1. Simply reduce the amount of liquid depending on the age:

Ages 1-3: 1/2 teaspoon (2.5ml)
Ages 4-12: 1 pump (4ml)
Ages 12 and over: full dose (2 pumps/8ml)

Can I take Complement Essential liquid 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.

Great so far; just a couple of minor drawbacks

I have the liquid versions of the core and essentials complements, and so far they have been great in terms of quality and flavor!
It also gives me that peace of mind knowing that I'm getting what may be missing in my diet (especially since I don't want to track all the things I eat and drink everyday like crazy!)

I think the only drawbacks I've noticed so far is the lack of space in my fridge (I have a small fridge), so having two giant bottles takes up a lot of space; and then fact that I seem to run out of the core liquid (smaller bottle) faster than the two giant essentials bottles, even though I'm following the dosages - maybe it's just because the core is in a pump bottle and it's harder to get out that last little bit (i.e. some may get stuck in the pump straw or can't get that last little bit at the bottom), but it could also be that "4 pumps" is not exactly accurate every time.

I also imagine if I wanted to travel anywhere by air, it may be a problem taking the liquids through security.

I guess those are just a few of things to keep in mind if you're trying to decide between the capsules and the liquid versions.

The drawbacks aren't that big of a deal, so I'd say it's still worth it, just not quite 5 stars ;)

personally, if it weren't more expensive, I might switch to the capsules - I guess that's just the extra price you pay for convenience.

Great Product!

This product gives me peace of mind for my family. We are vegans and we all take these everyday. I do not have to worry if my 19 month old is getting all his needs met. Highly recommend this product for everyone (especially those with picky toddlers).

Best plant based vitamins

I absolutely love Complement. I have a rare, congenital heart defect and have been taking these maximize my results along with my plant based lifestyle! I love the quality & third party testing. Customer service is also super friendly!
Thanks Complement

No more pills!

I’m on my second order of the liquid complement. I wasn’t tolerating all the separate tablets I needed to supplement my diet. It was a daily hassle to keep up with multiple bottles and even after I set up a daily/ weekly dispenser I missed doses. Now I get all that I need in a great tasting liquid once a day. Complement has never upset my stomach and since I look forward to it I never miss a dose. Customer service was very responsive to my needs. You should try it just to see how sustainably the product is packaged!

Best choice

I love complement because it has all the nutrients I need and none of the ones I do not. As a vegan, it is important to know all my bases are covered. This is the best on the market.
