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 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 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 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 a 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.

"Complement Essential is the first liquid vitamin combo I love taking every morning. Even as a whole food plant-based eater, not every day is a 'perfect eating day'. On top of that, there are a few essential nutrients complementing our diets with so we can thrive. It's so nice to know I'm getting those hard to get essential nutrients everyday in an all-in-one form (it's so easy to take every morning, mixed into my smoothie)."

good all-in-one supplement for vegans

Has many of the nutrients hard to get in a vegan diet. Also, iodine, which I appreciate, since I try to limit my table salt intake, which would be the main place I could find that nutrient otherwise.

I have to be careful...

I normally take two complement+ capsules per day first thing in the morning, and then I have some other supplements that I take at lunchtime. I ran out of my other supplements this week, and so I decided to take an additional dose (2 more capsules) of your product at lunch time. The boost in activity level and general happiness was so extreme that I think I will drop back down to 2 per day now that my other supplements came in. Those two in the morning are more than sufficient to carry me through the day! This is a great product!!!
