Your circulation controls everything in your body.
When blood flow slows down, the effects hit fast and hard. Your heart works harder, but less oxygen and nutrients reach where they're needed most. Suddenly you're dragging through afternoons, struggling to think clearly during important meetings, and noticing unwanted changes in your energy, mood, and even your bedroom performance. Your hands and feet feel cold. Simple tasks leave you winded.
That's why millions of Americans are turning to circulation supplements. It's a simple, natural way to target fatigue, brain fog, intimacy issues, and so much more right at the source—your blood flow.
But here's the frustrating catch: most formulas use cheap ingredients at doses too low to make any real difference. Others pack in so many random herbs that nothing works effectively.
That's where we, at Smarter Reviews, come in. Our team spent months testing the most popular circulation supplements on the market. This guide cuts through all the confusion with what actually works, what to avoid completely, and our top 5 circulation formulas that deliver real results for optimal blood flow and renewed vitality.
The Right Circulation Formula Can Help:
- Restore Optimal Blood Flow for All-Day Energy
- Promote Mental Sharpness
- Support Healthy Weight Management
- Enhance Overall Mood
- Strengthen Heart Health
Your Body's 37,000-Mile Highway System
Picture this: 37,000 miles of blood vessels carrying life-giving oxygen and nutrients to every cell in your body. When traffic flows smoothly, you feel unstoppable. But when circulation gets backed up like rush hour gridlock, everything slows down—your energy, focus, and vitality get stuck in the jam.
Over 100 MILLION Americans are dealing with this sluggish circulation right now, according to the American Heart Association. The right circulation supplement is like opening up the carpool lane—suddenly everything flows freely again.
What To Look For in a Circulation Supplement
Beetroot Extract
Beets contain tons of nitrate, which your oral bacteria convert into nitric oxide. This molecule relaxes and dilates your blood vessels to support circulation. Now, your body can make nitric oxide, but its production slowly declines as you age. 2 That’s why nitrate-rich beets are so important to consume.
Fiber
This superfood is missing from 95% of the American diet. 3 It’s widely-known to nourish your “good” gut bacteria and improve digestion. However, fiber also helps your body produce short-chain fatty acids, which can work wonders for your circulation and blood pressure. 4
Vitamins and Minerals
The “nutrient gap” in America is rapidly growing. Right now, a large portion of the U.S. population lacks many key vitamins and minerals — especially vitamins A, B, C, D, E, and folate. 5 So, it’s crucial to add them back into your blood flow.
The Little-Known Ingredient to Avoid
Magnesium Stearate
This cheap filler is often used in the manufacturing process to bind ingredients together. Yet, it doesn’t provide any nutritional value, whatsoever. Even worse, Magnesium Stearate is known to cause a number of unwanted side effects.
When it comes to choosing a premium circulation supplement, quality ingredients are the most important thing — but they're not the only thing. Here are a few other points to consider:
The “Extra Perks” Check-List
Non-GMO
Do you want anything “genetically modified” going into your body? Probably not. That’s why Non-GMO is the way to go. It also avoids pesticides, fertilizers, and other harmful substances.
Doctor-Formulated
The guidance and expertise of a well-respected doctor is a trustworthy “stamp of approval.” Plus, it ensures the formula has optimal ingredients and dosages.
Money-Back Guarantee
A health formula should always be backed by a 100% money-back guarantee. This “insurance policy” offers you peace of mind and allows you to try it risk-free.

Total Ranking
9/10
A+
Overall Grade
PROS
- 4000mg Beetroot Powder
- Contains Fiber
- Probiotics & Prebiotics
- Non-GMO
- Essential Vitamins
- 90-Day Money-Back Guarantee
CONS
- Only Sold Online
The Bottom Line
CardioFitMD™ is made from a blend of 2000mg of beetroot powder and 2000mg beetroot juice powder. Having both allows you to get more concentrated nitrate content from the juice.
CardioFitMD™ also contains every key letter vitamin as well as fiber, probiotics, and prebiotics, all of which give a boost to its circulation support.

Total Ranking
8/10
B+
Overall Grade
PROS
- Contains beetroot powder
- Includes L-citrulline and hawthorn berry
- Vitamin C and B12
- Lozenge format for sublingual absorption
CONS
- Proprietary blend - only 420mg total N.O. ingredients
- Severely underdosed (10-30x less than research suggests)
- No fiber for heart health
- No probiotics
- Missing the most essential vitamins
- Premium pricing at $2 per lozenge
The Bottom Line
Circ02's lozenge delivery system offers better absorption than capsules and includes legitimate circulation ingredients like beetroot, L-citrulline, and hawthorn berry.
The dealbreaker: Circ02's proprietary blend contains just 420mg total. Research shows effective L-citrulline doses range from 4,000-12,000mg daily—meaning Circ02 delivers 10-30x less than studied amounts. Beetroot dosage is equally unclear and likely falls far short of the recommended 3,500-4,000mg.
Critical omissions compound the problem: no fiber for heart health and weight management, no probiotics for gut-heart connection, and it's missing most of the essential vitamins and minerals that maximize circulation benefits.
At $2 per lozenge for severely underdosed ingredients and incomplete nutrition, Circ02 can't compete with comprehensive formulas delivering research-backed amounts.

3. Nitric Oxide Organic Beets
Total Ranking
8/10
B+
Overall Grade
PROS
- Organic Beetroot Powder
- Vitamin B
- Bioperine for Max Absorption
- 90-Day Return Policy
CONS
- Unclear Beetroot Dosage
- No Vitamins
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.

4. BioBeet Juice
Total Ranking
7/10
B+
Overall Grade
PROS
- 3g Beetroot Juice Powder (Highly Concentrated)
- Great Reviews
- 90-Day Money-Back Guarantee
CONS
- No Vitamins
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.

Total Ranking
7/10
C+
Overall Grade
PROS
- 3g Organic Beetroot Powder
- 90-Day Return Policy
- 90 Servings
CONS
- No Vitamins
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.
