Beetroot has an unusual advantage over many products sold for circulation.

There is a well-established biological mechanism behind the interest.

Beetroot naturally contains dietary nitrate. After consumption, nitrate can be converted through the nitrate-nitrite-nitric oxide pathway.

Nitric oxide helps regulate blood-vessel tone and blood flow.

That is why a beetroot powder supplement can be relevant well beyond simply adding another vegetable powder to your smoothie.

The same pathway explains why beetroot attracts attention across several apparently unrelated areas.

Athletes are interested in oxygen efficiency and exercise performance.

Researchers investigate cardiovascular and blood-pressure responses.

And healthy circulation is obviously relevant anywhere blood flow matters throughout the body.

Propel Health uses a simple air-dried beetroot powder rather than building an enormous proprietary “nitric oxide” formula around it.

It is also independently tested as part of Propel Health’s quality program, including testing for contaminants such as pesticides, glyphosate, mould and E. coli.

Sometimes the interesting ingredient doesn’t need to be invented in a laboratory.

The beetroot already did most of the work.
