Replace your supplement drawer

Now you know the gaps. Here’s what we built to close them.

You just spent 45 minutes with Cyrus learning about the 6 nutrients most plant-based eaters quietly miss. You saw the science. You got the food-first plan. And you heard Cyrus be honest about the two nutrients — K2 and DHA — that food alone can’t realistically cover.

That’s why Essential exists.

We didn’t build Essential to replace a good diet. We built it to complete one. The 6 nutrients from tonight’s webinar, plus B12 and D3, all in one capsule. Researched doses. Third-party tested. Nothing extra.

As a thank you for showing up tonight, we’re offering 30% off your first order. This offer is only available on this page and it’s only here for 48 hours.

As seen on

The 6 nutrients from tonight. Plus the 2 you already know about.

You don’t need us to explain these again — Cyrus just did that for 45 minutes. But here’s what matters: how Essential delivers each one.

Zinc

Optimized for absorption, formulated to work around the phytates Cyrus talked about.

Selenium

Full daily dose. Because relying on soil quality to get it from food is a coin flip, depending on where your produce was grown.Aljezur

Iodine

The one that quietly disappeared when you switched to sea salt. It’s back.

Magnesium

The master mineral. 600+ reactions. If you’ve been dealing with cramps, restless legs, or rough sleep, start here.

Vitamin K2 (MK-7)

Cyrus was straight with you: unless you eat natto every day, food alone isn’t going to cut it. MK-7 is the most bioavailable form. It keeps calcium in your bones and out of your arteries.

DHA & EPA (470mg+ from algae)

Remember the less-than-1% conversion rate from flax that Cyrus showed you? That’s why Essential goes straight to the source: algae. 48% more omega-3 than the leading competitor. No fish, no mercury, no middleman.

Ingredients

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.

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.

DHA/EPA Omega-3s - 470 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.

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.

Magnesium - 200 mg:
Soil depletion is a major cause of Magnesium deficiency in the overall population, and affects vegans as well as non-vegans.

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).

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.

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.

Who is this for?

COMPLEMENT Essential is for people who eat a plant-forward or plant-based diet and want a simple, reliable way to support long-term health without overcomplicating supplementation.

It is designed to complement a healthy whole-food diet by providing key nutrients that are commonly underconsumed in plant-forward eating patterns, including vitamin B12, vitamin D3, iodine, zinc, selenium, and plant-based omega-3s.

If your goal is to support longevity by nourishing your heart, brain, immune system, and overall vitality so you can feel like your most vibrant self each day, COMPLEMENT Essential is for you.

The science

Instead of cramming together dozens of vitamins and minerals you're already getting through food, Complement Essential focuses on the 8 hard-to-get nutrients, in dosages that make a difference.

How to use Essential

Take 3 capsules daily with a meal.

Taking Essential with food helps support optimal absorption of fat-soluble nutrients and omega-3s, and is gentle on digestion.

For best results, use consistently as part of your daily routine alongside a balanced, whole-food diet and healthy lifestyle.

“I’ve spent 20 years studying how food works at the cellular level. I know how hard it is to get everything right from food alone — especially K2 and DHA. When I looked at what was in Essential, the forms, the doses, the sourcing, I didn’t just endorse it. I started taking it. It’s what I’d want if I’d built it myself.”

— Cyrus Khambatta, PhD

The simplest way to fill the gaps & support long-term health.

Tonight you learned something most plant-based eaters never find out: that eating well isn’t always enough, and that the gaps don’t announce themselves until it’s late.

You also learned that most of it is fixable with food. And for the couple that aren’t, there’s Essential.

We built it for people exactly like you — people who chose plants on purpose and want to make sure that choice works for them long-term.
Try it. You have 100 days to decide if it’s right for you. And if it’s not, you get every penny back.

Frequently asked questions.

What exactly is in Essential?

The 6 nutrients from tonight’s webinar (zinc, selenium, iodine, magnesium, K2, DHA/EPA) plus B12 and D3. All in researched doses. Nothing else.

How long do I have to use this offer?

48 hours from when the webinar ended. After that, this page goes away.

Can I cancel the subscription?

Anytime. No hoops. No “call this number between 9 and 5.” Just click cancel in your account.

What if I don’t like it?

100-day money-back guarantee. Not 30 days. 100. If you’re not happy, you get a full refund. We’ve been doing this for years and we stand behind it.

I already take B12 and D3 separately. Why switch?

Because tonight Cyrus showed you there are 6 other nutrients you’re probably not covering. Essential replaces your B12 and D3 AND adds the 6 gaps you just learned about. One capsule instead of a drawer full of bottles.

Is this available anywhere else at this price?

No. 30% off first order is exclusive to this page for webinar registrants. It’s not on our website, not in our regular emails, and won’t be repeated.
