"The effect is attributed to the high nitrate content of the beetroot."
Professor Ahluwalia said. “We gave inorganic nitrate capsules or beetroot juice to healthy volunteers and compared their blood pressure responses and the biochemical changes occurring in the circulation.
“We showed that beetroot and nitrate capsules are equally effective in lowering blood pressure indicating that it is the nitrate content of beetroot juice that underlies its potential to reduce blood pressure. We also found that only a small amount of juice is needed – just 250ml – to have this effect, and that the higher the blood pressure at the start of the study the greater the decrease caused by the nitrate.
“Our previous study two years ago found that drinking beetroot juice lowered blood pressure; now we know how it works.”
It's more likely that Controlled Labs added "Beet Root" to take advantage of the current nitrates trend, while not paying for actual nitrates. The amount of nitrates in beet root are fairly minimal.
Cool, any info for the OP regarding his question?
