The Bottom Line

Despite its name, Essential Elements' Pre-Workout is a great circulation supplement -- even if you're not about to go hit the gym.

It’s filled with an optimal 4-gram dosage of beetroot for the circulation support you deserve. Coupled with a full supply of Vitamin C, this pre-workout helps you sustain effortless energy throughout the day.

Now, let’s talk about some minor drawbacks…

Unfortunately, this supplement does lack many important vitamins. This can limit its role in weight management and cardiovascular health.

We'd also like to note that Essential Elements’ Pre-Workout contains about as much caffeine as a cup of coffee.

All in all, though, this pure, high-quality formula and impressive 365-day money-back guarantee earn Pre-Workout the #2 spot on our list.

The Bottom Line

The core of Nitric Oxide Organic Beets is a proprietary blend that includes beetroot, pomegranate, and more. It also has a generous amount of Vitamin B and some Vitamin C, which makes Nitric Oxide Organic Beets a strong option for a circulation support.

However, since this supplement uses a proprietary blend, it's difficult to tell how much beetroot it actually contains.

What's more, Nitric Oxide Organic Beets is also missing many key vitamins. So, its health benefits may not be as far-reaching as you'd like to see. 

Still, this is a strong formula backed by a 90-day money-back guarantee. That's why it was an easy decision to give it the #3 spot.

The Bottom Line

Coming in at number 4 on our list is BioBeet Juice. This product has a simple formulation as it's just 3g of organic beetroot juice powder and silica to prevent clumping.

While pure, this product leaves out fiber, probiotics, and vitamins -- all key ingredients for maximum energy and heart health support. 

However, most customers reported seeing glowing results since starting this supplement, so we had to include BioBeet Juice on our list.

The Bottom Line

Last on our list is KOS Organic Beet Root Powder. It's simply organic beetroot powder and nothing else.

Like others on our list, it's also certified organic, non-GMO, gluten, and keto-friendly.

We appreciate the simplicity of this product and it's an all-around solid choice, especially if you're new to circulation supplements. However, it also lacks several vitamins, which may be a turn-off for people looking for something with more bite behind it.
