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.

Complement Core provides the missing nutrients 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 Core 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, and D3 all work together to support a healthy cardiovascular system.

 

Enhance Immunity

Vitamin D3 has been shown to help boost immunity and fight against certain diseases.

Stronger Bones

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

 

Family Friendly

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

The Complement Core formula.

 

Premium plant-based nutrition.

The Big 4

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

The Smart Parts

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

The Liquid Spray

With a minimalist liquid formula, Complement Core is designed for use by the entire family. Simply spray the nutrients directly into your mouth or onto food to fortify your smoothies, salads, or meals.

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 Core 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.

Fully transparent production.

Complement Core 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 done in pharmaceutical-grade facilities that are FDA Registered, NSF Certified, 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 NSF facility, and tested for yeast and mold, and possible bacterial presence, such as Salmonella, E.coli and other coliforms.

The Complement guarantee.

 

We want you to love Complement as much as we do.

 

If within 30 days of receiving your order, you're not absolutely thrilled with the degree to which Complement has completely simplified the process of supplementing your plant-based diet, just send us back the bottle and we'll refund 100% of your purchase price, no questions asked. We're here to strengthen this movement that we so strongly believe in — so we're not happy until you are.

Find out what they're 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?"

Can my children take Complement?

Yes! We formulated the new Complement Core so they can be used by everyone in your family.

The dosages below are based on the Recommended Daily Allowance (RDA) for children from the National Institutes of Health.

As with all dietary supplements, we recommend that you consult your pediatrician before using Complement Core for your children, as their needs might be different.

Dosage:

Ages 1-3: 2 pumps (1ml)
Ages 4-12: 3 pumps (1.5ml)

I prefer to take pills. Do you offer Complement in pill form as well?

Should I spray this directly in my mouth?

Complement Core has a pleasant citrus taste and can be sprayed into your mouth. You can also fortify your own food by adding Complement to a smoothie, salad, or power bowl! To preserve the high quality ingredients and potency of the nutrients, it is best to spray Complement on to cold or warm foods (not hot) and enjoy within 20 minutes. (For the same reasons, please refrain from cooking Complement Core!)

Convenience Wins!

Has a slightly fishy taste to it but the convenience of getting all that I need in one place (rather than multiple bottles) easily outweighs the need to chase it with something. Love it so far! Wish there was a way to tell if I am getting a full “pump” — the pump presses down all the way but sometimes I feel like less liquid comes out. These are modifiable things, though. I really appreciate the Complement team for thinking about plant-based people like myself!

Feel great, but taste is not

I love the way I feel taking Complement Core, and it’s exactly what I need all in one formula. Other vitamins have made me tired or give me headaches, but this one seems to be just right. The one downside is it tastes terrible. It tastes like fish even though I know there’s no fish in it. I just take it quickly and chase it with water and food immediately. I will definitely keep taking it, but hoping one day the flavor will improve.

Great product!!

I love the ingredients, and how basic it is with just what i need. I've only been taking it for almost 2 weeks, but I have more energy and feel less brain fog.
