Power Beets: A Humble Root with Surprisingly Good Chemistry

For years, beets sat beside dinner looking as though they had stained something and were waiting to be questioned.

Now beetroot turns up in sports nutrition and circulation research. That is quite a career move for a vegetable many of us first encountered in a jar at Grandma's house.

So what is behind the attention—and where does Nature's Sunshine Power Beets fit?

 

The interesting part starts with nitrate

Beetroot contains dietary nitrate. Bacteria in the mouth help convert nitrate into nitrite, which the body can then use to produce nitric oxide. This signalling molecule helps blood vessels relax. [2]

That pathway gives researchers a sensible reason to study nitrate-rich beetroot juice for blood pressure and exercise. A plausible mechanism, however, is the beginning of the investigation. It is not a guarantee that every beet drink produces the same result.

Can beetroot help with exercise?

Some research is encouraging. In a small 2009 experiment involving eight men, nitrate-rich beetroot juice reduced the oxygen cost of moderate exercise and increased time to exhaustion during more intense exercise. [3]

That does not mean everybody becomes faster, or that an improvement in a laboratory exhaustion test translates directly into the same percentage improvement in a race.

More recent results illustrate the limits. A 2026 randomized crossover study in 12 trained male sprinters found that a single serving of nitrate-rich beetroot juice did not improve their 60- or 100-metre sprint performance. [4]

The useful message: the person, activity, dose and testing conditions matter. Beetroot has interesting potential. It has not made training optional.

Your running shoes may relax. Their job is safe.

What about blood pressure?

A 2015 randomized trial assigned 68 people with hypertension to nitrate-rich or nitrate-depleted beetroot juice for four weeks. Researchers found blood-pressure reductions with the nitrate-rich juice. [2]

That is evidence for a specific preparation under specific conditions. It does not establish that Power Beets treats hypertension or prevents heart attacks. The researchers also cautioned that their short trial could not establish long-term cardiovascular outcomes.

If you take blood-pressure medication or have a medical condition, ask your pharmacist or clinician before adding a supplement marketed for circulation. Keep prescribed treatment in place.

Where Power Beets fits

The current Canadian Nature's Sunshine listing describes a powder providing 30 servings. Its ingredient panel lists 3,000 mg of beetroot, along with L-arginine, inulin, vitamin C and other nutrients and plant ingredients. Directions say to mix it into one to two cups of liquid immediately before drinking and take it with food. Follow the current Canadian package for complete directions and cautions. [5]

The practical appeal is convenience: a measured powder that fits a routine without preparing beetroot juice from scratch.

But here is a detail worth understanding: 3,000 mg of beetroot is not 3,000 mg of nitrate. The online ingredient panel reviewed for this article does not state a standardized nitrate amount per serving. It therefore cannot establish that one serving matches the nitrate dose used in a particular study.

Likewise, research on an ingredient does not automatically demonstrate the effects of the finished blend. The sources reviewed here do not establish a clinical trial of the complete Canadian Power Beets formula.

Buy with curiosity—and read the label

When comparing beet products, look beyond the large number on the front. Check serving size, ingredients, directions and whether a nitrate amount is actually disclosed.

Think about the job you want the product to do. Convenience is a fair reason to choose a powder. Expecting a supplement to compensate for too little movement, sleep or balanced food asks rather a lot of a beet.

Power Beets can be considered as an addition to a wellness routine. Its strongest introduction is an honest one: a convenient beetroot formula built around an interesting area of nutrition science, with benefits that should be judged against evidence and the current label.

The beet has earned our attention. It still has to earn each claim.
