A person with gray hair sits in a kitchen, smiling. They are wearing a black jacket and are next to a package labeled Complement Essential, which is on the counter beside a small teal plate and some bananas.

I'm always asked which supplements I take, and I used to say... only B-12... unless there's a known deficiency.

However, as the science has progressed, so has my recommendation.

I now focus on a handful of hard-to-get nutrients, and Complement's all-in-one multi makes it simple, with a formula specifically designed for plant-based eaters.

PLANTSTRONG follows the science for long-term health.

At PLANTSTRONG, we follow a whole-food, plant-first philosophy. After all, when you look at the research, whole plants are the most nutritious foods available to us.

But we all live different lifestyles, have different goals, and process foods in our own unique ways. That same research that highlights the power of plants for long-term health also identifies a few key nutrients and omega-3s that, while technically available in plant foods, aren't always consumed in adequate amounts.

That's where Complement Essential comes in. It's the perfect complement to a PLANTSTRONG diet to help you live your best, happiest life, today and for the long-term.

Do Plant-Based Eaters Need A Multi (When Their Food is Already Healthy)?

As a plant-based eater, you’re already following the healthiest and most responsible diet on earth, enjoying an abundance of most nutrients with every meal and supporting foundational long-term health. But, if you rely on whole foods alone, chances are you’re still missing a few key nutrients — and there’s (almost) nothing you can do about it.

A lack of complete nutrition can, at best, make you function at less than your peak. At worst, it can lead to serious health problems down the line.

But don’t take our word for it…

Look at the Statistics

Up to 86.5% of adult and elderly vegetarians are at risk for Vitamin B12 deficiency.1That affects their energy and brain function.
More than 41% of Americans are deficient in Vitamin D,2 which is crucial for bone and immune health, as well as many other systems. Several health experts believe that D should also be taken in combination with Vitamin K2, to ensure the safe transport of calcium in the bloodstream*.
Despite having access to iodized salt, mild-to-moderate iodine deficiency is a public health concern in 30+ countries.3 Iodine is key for the metabolism.
Due to plant compounds that reduce absorption, vegetarians may need 50% more zinc than omnivores.4 Low zinc levels can impair immune system function.
Most vegans get their omega-3s from nuts, seeds, and oils. These contain alpha-linolenic acid (ALA), which converts to DHA and EPA in the body, but at a very poor rate. Research shows that only 8% of dietary ALA is made into EPA in healthy young men, and 4% or less converts to DHA.5

So what’s going on here? Why can’t plant-based eating alone cover all bases?

Here are 3 good reasons:

Hands gently pouring soil, surrounded by a circular frame. A large blue number 1 is in the lower left corner. The background shows a dry, earthy surface.

Your food is weaker than it used to be.

A United Nations’ study reports that 33% of the world’s soil resources are degraded — largely due to industrial agriculture.6 Poor soil quality negatively impacts the nutrition in our food, as well as its production and sustainability.

A person eating noodles with chopsticks from a white takeout carton, smiling. The person is wearing a white shirt, and there is a large blue number 2 in the bottom left corner of the image.

You eat the same stuff.

Think about how many of the same foods and meals you eat week after week. A review in Molecular Metabolism revealed that 75% of the world’s food comes from only 12 plants and five animal species.7 That’s not enough variety to ensure optimal nutrition.

A variety of healthy foods including a halved avocado, bowls of pumpkin seeds and flaxseeds, a cracked coconut, almonds, and chia seeds arranged on a light blue surface. A large number 3 is in the bottom left corner.

Your body can’t absorb some nutrients, and can’t access others.

Plant-based sources of vitamin B12 and Vitamin D aren’t as bioavailable as their animal counterparts, and omega-3 fatty acids like DHA and EPA are nearly impossible to obtain in adequate amounts from a standard plant-based diet.

So what’s the solution?

In some cases, eating more of specific foods rich in the hard-to-get nutrients might help, since that would add more of those nutrients into your diet. But that's not always practical (you'd have to be munching seaweed all day every day to get enough DHA and EPA omega-3s, for example — and then you'd overdose on sodium and iodine).

You could also add individual supplements to your diet to fill in the gaps, but then you’d have to micromanage each one to make sure you’re getting enough, and in the right amounts. Plus, the cost of those individual bottles would add up quickly.

So how about taking a typical multivitamin?

Well, now you’re overcorrecting the problem, paying for a bunch of nutrients you’re already getting from your plant-based diet. You’ll end up peeing out the excess. Talk about money down the drain… And you’re still not getting those omega-3s.
