Finally, a Simple Way to Get Everything that Might Be Missing from Your Plant-Based Diet
(And Nothing That's Not)
"Ever since I helped to create Complement™, my family and I have enjoyed the peace of mind that comes from knowing we're getting three critical nutrients (Vitamin B12, Vitamin D3, and DHA/EPA) missing from most plant-based diets. 

It's such a relief to know that Complement™ provides those — without all the unnecessary extras in most multivitamins, and produced by experts who we know personally and trust with my children's health.  So that we can eat plant-based and know that we're getting everything we need. And, most importantly, so that I can know beyond a shadow of a doubt that I'm setting my children up for long-term health."

Why Complement Your Plant-Based Diet?

There are a lot of nutrients we could have included in Complement™. But those who know the value of a whole-food, plant-based diet know that more isn't necessarily better. Our team, led by our Director of Science and Education, a Ph.D. in Nutrition and a plant-based registered dietician, ultimately decided that the original formulation of Complement™ should include only those essential nutrients not found in plants, so that you can get the rest of your nutrients from your food, the way nature intended. Here's why top doctors and researchers in the plant-based community believe it's so important to get each of the three nutrients Complement™ provides:

Life relies on soil, but the life in our soil isn't what it used to be. Soil bacteria produce Vitamin B12 — which is essential for humans in order to protect neural health and reduce inflammation. But modern agriculture and other human behaviors decimate these bacterial colonies that produce B12. On top of that, in our super-sanitized world, we thoroughly wash food, which further reduces the chances of ingesting a sufficient amount of B12 through natural sources.

Vitamin B12 deficiency is common among people following a plant-based diet. In a review including 13 studies with vegan participants, 10 studies reported at least 20% of vegan participants were B12 deficient. Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis, and for avoiding pernicious anemia.

Complement™ contains 1,000 mcg of B12 (methylcobalamin) per daily serving.

We've all heard of the importance of Omega-3's, but vegan food sources like flax and chia seeds don't provide two essential types — namely DHA and EPA. Seeds provide ALA Omega-3's, and are an amazing addition to your plate, but vegans may not adequately intake DHA and EPA, which are critical for cardiovascular and brain health (nor do most people adequately convert ALA into DHA and EPA).

Omega-3’s play a key role in nearly every cell of your body. As such, a daily intake of these essential fatty acids is critical for optimal functioning — from regulating your cholesterol levels to powering your nervous system. Omega-3's may also help to prevent rheumatoid arthritis, ADHD, asthma, and depression. One of the most important functions, which we are just recently beginning to appreciate, is controlling the low-grade, systemic inflammation that is tied to many chronic diseases.

Complement™ includes 300 mg of DHA and 70mg of EPA, per daily serving, sourced from lab-grown algae to ensure purity.
