I have switched from orange juice to cran-pomegranate juice in the mornings mainly for the blood pressure lowering effects. We'll see if it works, along with beets added to the evening meal.
But supplementation is known for not being the best way to get vitamins/minerals, they should have tested juice or real fruit. Once again researchers not knowing all they should in their areas of research.

Pomegranates have been found in previous studies to help prevent
heart disease but a new study found extracts from the fruit have no
effect on most cardiovascular risk factors.
Juice from the fruit has been shown in previous studies to slow the growth of prostate cancer, fight bacteria and cavities, benefit diabetes patients, and as an aphrodisiac, in addition to having benefits to lower heart disease risk.
Researchers in the new study, published in the Journal of Medicinal Food,
recruited 33 hemodialysis patients, who are generally at higher risk
for heart disease, to test the expected oxidative effects of the juice,
as well as other benefits expected to prevent heart disease.
The 33 participants under age 30 who were all receiving hemodialysis
treatment three times a week for less than three months at the start of
the study who were randomly assigned to receive 1000 mg capsule of
purified pomegranate polyphenol extract or placebo every day for six
months.
While researchers found there were some reductions in patients' blood
pressure and noted some atheroprotective benefits, the extract had no
effect on inflammation, oxidative strength, or muscle strength -- in
effect, little to no effect on either risk factors for heart disease or
kidney function.
"Pomegranate supplementation had no effect on any other metrics of
cardiovascular risk or physical function in our patients," researchers
wrote in the study. "Taken together, these data suggest that pomegranate
extract supplementation may provide limited benefits in terms of
reducing the development or progression of comorbidities in patients
with chronic renal failure."
