SuperBeets Review: Effective Supplement or Hype? Our Dietitian Explains
SuperBeets is a beet-based dietary supplement designed to provide a highly concentrated dose of nitric oxide. Although the ingredients in this product do support healthy blood pressure and circulation, it is not a “quick fix” for heart health.

HumanN SuperBeets is a dietary supplement line designed to support cardiovascular health and energy levels.
The main product is a powder made from concentrated beet crystals and comes in Original Apple or Black Cherry flavors.
The brand claims that by taking a concentrated source of nitric oxide, you will experience better circulation and blood pressure management and less fatigue.
SuperBeets products are formulated to provide a large dose of nitric oxide. According to the brand, just one serving of the Original supplement delivers the nitric oxide equivalent of eating three whole beets.
Nitric oxide (NO) is a vasodilator, a compound that works by relaxing the smooth muscle in the body and dilating blood vessels.
This results in increased circulation, which theoretically lowers blood pressure and allows more oxygen to enter the bloodstream.
High blood pressure is a known risk factor for developing cardiovascular disease and kidney disease.
This is a condition in which blood vessels are constricted, causing blood to push on the walls of your arteries at higher than normal force.
People with high blood pressure are thought to have a lessened ability to utilize nitric oxide.
Additionally, nitric oxide is involved in respiratory health. It plays a role in regulating smooth muscles throughout the airway and vascular system, supports lung development, transports mucus, produces surfactant, and acts as a neurotransmitter and mediator.
There are dietary sources of nitric oxide in the form of nitrate compounds, which have been shown to benefit blood pressure.
The best food sources of beneficial nitrates include fruits and vegetables, especially beets and dark leafy greens like spinach, kale, and arugula.
When you consume food sources of nitrates, your body converts them into nitric oxide.
SuperBeets claims to take nitrates from beets and encapsulate them into dietary supplement form so that you get a highly concentrated dose of plant-derived nitric oxide.
My main issue with SuperBeets products as a registered dietitian stems from the fact that the best dietary sources of nitric oxide are healthy foods that should be encouraged as a regular part of a healthy diet.
Promoting nitric oxide supplements as a solution to reduce high blood pressure comes across as encouraging a “quick fix” in place of dietary and lifestyle habits that are known to promote long-term health.
Non-GMO beetroot powder is the major ingredient in SuperBeets Original, with natural cherry or apple flavor, stevia, malic acid, and magnesium ascorbate to preserve the freshness, color, and quality of the product.
This product also contains vitamin C for antioxidant support.
It does not say how much beetroot powder is in the product, but I assume this takes up most of each 5-gram serving.
While a supplemental source of nitric oxide may not be the ideal solution for lowering blood pressure, the benefits of the beetroot powder used in the SuperBeets are widely supported by research.
The evidence behind many of the claims made about the beetroot powder and vitamin C in this product is detailed below:
Beetroot Powder, 5 g
There has been a significant amount of research done around the nitrate-related effects of beetroot in regards to blood pressure regulation, exercise performance, and circulation.
This appears to affect your systolic blood pressure most, which is when your heart contracts.
Nitrates may help your mitochondria function more efficiently, which is where energy production occurs in the body.
This would help explain why beetroot could help improve energy levels and combat fatigue.
However, a 2019 randomized controlled trial found that while citrulline malate and beetroot juice supplementation improved nitric oxide during maximum effort leg extension exercise, it did not have an effect on energy, performance, blood flow, or metabolic efficiency compared to placebo.
A 2015 review noted that beetroot offers numerous antioxidant, anti-inflammatory, and vascular-protective effects that have been demonstrated in multiple in vitro and in vivo human and animal studies.
A 2018 review of 11 clinical trials related to beetroot and hypertension concluded that beetroot is a cost-effective strategy worth utilizing to lower blood pressure and risk for cardiovascular events in at-risk populations.
The researchers concur that this is most likely due to the nitrate conversion to nitric oxide as well as other beneficial compounds found in beets.
Still, dietary nitrates only stick around in the body temporarily and require regular consumption for long-term effects, which is a good selling point for supplements.
Vitamin C, 50 mg
SuperBeets contains magnesium ascorbate, a non-acidic or “buffered” form of vitamin C containing magnesium.
This form of vitamin C is absorbed well by most people and possibly more easily tolerated, though research to confirm this is lacking.
It’s also involved in wound healing, maintaining gum health, fighting off infections, and a number of immune functions.
Long-term vitamin C supplementation has also been observed to promote nitric oxide synthesis and improve vascular endothelial function in rats.
A more recent 2021 randomized controlled trial found that 1000 mg of vitamin C taken daily for 6 weeks reduced pre-exercise and post-exercise blood pressure, improved oxidative stress, and encouraged nitric oxide production among 24 adults with poorly controlled type 2 diabetes.
And in a 2012 review of 29 trials, researchers found that vitamin C supplementation, averaging 500 mg per day for 8 weeks, was successful in reducing high blood pressure.
It’s important to note that the most abundant sources of vitamin C are fruits and vegetables, but SuperBeets contains at least 50% of the RDA for most adults.
Overall, there’s certainly evidence for the benefits of both dietary nitrates and vitamin C, particularly for heart and endothelial health.
Still, both can be found widely in whole plant sources that can easily be incorporated into the average diet.
Below is our summary of the available evidence for the claimed benefits of SuperBeets based on the available research:

- Promotes nitric oxide productionGold Star Evidence
- Provides antioxidant support with an excellent source of Vitamin CGold Star Evidence
The serving size of SuperBeets Original is 1 teaspoon (5 grams) to be mixed and consumed with 4–6 ounces of water.
The product states that you should not consume more than two 5-gram servings within a 24 hour period, though it’s unclear why this is. The answer to this question is not detailed in the FAQs section of the product page either.
While beetroot powder appears to be generally low risk, there are always potential risks from using any supplement.
Concentrated doses of beetroot may color your urine and stools red for a few days.
The other most common acute side effects from dietary nitrate supplements include headaches and stomach discomfort.
It’s always best to ask your doctor before adding any new dietary supplements to your routine to make sure it’s appropriate for you.
Additionally, there may be underlying acute or chronic issues that may be related to high blood pressure.
If you have concerns about your blood pressure, these should be properly addressed by a physician.
The best place to purchase SuperBeets products is directly from the HumanN website or on Amazon, where HumanN does have a storefront.
The HumanN SuperBeets Original supplement is priced at $39.99 for a 30-day supply.
If you sign up to receive a monthly subscription of the product, you can get it at a reduced price of $34.95 and pay no shipping.
A perk to purchasing this product directly from the brand is that HumanN offers a 90-day money-back guarantee.
If you are not fully satisfied with the product, you can return it within 90 days of the date you ordered it for a full refund of the purchase price, excluding shipping and handling.
If you live outside the continental United States, you will have to pay the corresponding shipping costs to return it.
This price seems on par with many other supplement products that come in similar supply sizes.
Still, this money could also be spent to include a variety of natural dietary sources of nitrates in your weekly grocery shopping that also contain vitamins, minerals, fiber, and antioxidants.
The full SuperBeets line of products from HumanN includes:
- SuperBeets Original (concentrated beet crystals)
- SuperBeets Heart Chews
- SuperBeets Memory & Focus
- SuperBeets ENERGY PLUS
- SuperBeets IMMUNE
- SuperBeets COLLAGEN
The entire SuperBeets product line is based on non-GMO beetroot powder. Except for SuperBeets Original and SuperBeets Memory & Focus, they also all contain grapeseed extract.
These two base ingredients may support heart health by reducing high blood pressure, with additional ingredients for targeted benefits.
The Heart Chews and Memory & Focus are chewables, while the rest of the products are powders formulated for specific purposes.
The powdered products are suggested to be mixed with water or blended in a smoothie to drink, whereas the chewables are designed to be taken orally.
Powdered SuperBeets Products
SuperBeets ENERGY PLUS contains green tea extract with 80 mg of caffeine per serving, which may benefit memory and attention.
SuperBeets COLLAGEN contains collagen types I and III plus vitamin C, an essential cofactor for collagen synthesis. Collagen supplementation may help benefit joint health and even improve symptoms of osteoarthritis for some people.
Chewable SuperBeets Products
SuperBeets Heart Chews appear to simply be the more portable version of the original SuperBeets powder.
SuperBeets Memory & Focus chews contain coffee fruit extract, which may help improve cognition, and polyphenol resveratrol, which may have antioxidant effects and trigger mitochondrial biogenesis in the brain.
Overall, the beetroot powder and grapeseed extract that make up the base of most of the SuperBeets products may offer heart health benefits.
If you’re looking for immune, joint, or brain health support, the other products do appear to contain additional ingredients with some evidence behind their use for these purposes, though effects may differ between individuals.
There are many similar products to SuperBeets on the market, with beetroot powder as the primary ingredient. However, many seem to be standalone offerings.
SuperBeets, on the other hand, is offered in five unique formulations. Each has something different added to give it a targeted purpose.
As detailed in the product line section above, they have an immune support version, an energy-focused version, a version with collagen, and options that come as soft chews for memory and heart health.
As far as cost, SuperBeets Original comes in at around $7/ounce compared to many other brands, which seem to fall between $2.5–$5/ounce.
While SuperBeets Original is more expensive, it offers a unique product compared to alternatives, and there is evidence behind its ingredients that may prove beneficial for some people.
In addition, SuperBeets mixes easily with water and has a pleasant taste, especially compared to some other beetroot powder supplements.
Beetroot powder is the primary ingredient in the SuperBeets product line, which does have evidence in support of its benefits for blood pressure and healthy circulation.
Using this product may help improve energy levels and reduce high blood pressure levels in some people, though it should not be relied upon solely for these purposes.
High blood pressure can have multiple underlying causes, so just adding a dietary supplement in hopes of addressing the problem is unlikely to work, especially because it requires consistency for long-term benefits.
If you are concerned about high blood pressure and low energy levels, it’s best to take an overall look at your health and lifestyle habits. These should be properly evaluated by your physician.
Often, you can make more effective changes in your everyday eating and activity pattern that can have lasting impacts.
Furthermore, you may find that you need to work closely with your primary care provider to address the need for blood pressure medication or stress management.
Taking a supplement that can quickly become costly and may not be effective for everyone may not be worth it.
As there are risks with taking any supplement, speak with your doctor before adding a new one to your routine.
As a registered dietitian, a nitric oxide supplement would not be my first recommendation to lower high blood pressure levels and increase energy.
This is because there is so much evidence surrounding the effectiveness of other dietary and lifestyle modifications in achieving and maintaining healthy blood pressure.
Additionally, a healthy diet full of natural sources of nitrate also offers vitamins, minerals, fiber, and antioxidants.
However, there is evidence to back up the use of beetroot to support healthy blood pressure, so it may prove beneficial as a complementary and temporary tool for some people, with the guidance of their doctor.
