Pomegranate fruit originating from the tree Punica
granatum has long been thought to possess general health and anti-cancer
properties via its high concentration of polyphenols and anti-oxidants,
particularly ellagic acid.
Why are antioxidants and plant polyphenols important?
Polyphenols are natural plant based chemicals found in healthy foods which enhance our health and protect us from illnesses. Their antioxidant properties protect us from environmental and ingested chemicals which damage our DNA via a process called oxidation. Many studies have linked anti-oxidant rich foods with a lower risk of cancer and other chronic illnesses such as high cholesterol, dementia, arthritis, skin aging and macular degeneration (blindness). There are studies which report that the polyphenols and anti-oxidants in pomegranate could have an anti-cancer effect.
Anti-cancer properties of pomegranate
studies show it inhibits cell growth and induces apoptosis in androgen sensitive
human prostate cancer cells and implanted animal models [Retitig 2008].
In humans, in a phase II study, the PSA doubling time (PSAdt)
significantly prolonged from 15 to 54 months in men with PSA relapse given 200ml
pomegranate juice a day. The serum baseline oxidative state also significantly
lowered after consumption [Pantuck 2006]. This was supported by a study from
Johns Hopkins which gave men with PSA progressive prostate cancer, pomegranate
seed extract for 6 months. The PSAdt extended from 12 to 19 months and androgen
levels in men did not change [Carducci 2011].
Laboratory studies show it inhibits cell growth and induces apoptosis in androgen sensitive human prostate cancer cells and implanted animal models [Retitig 2008]. In humans, in a phase II study, the PSA doubling time (PSAdt) significantly prolonged from 15 to 54 months in men with PSA relapse given 200ml pomegranate juice a day. The serum baseline oxidative state also significantly lowered after consumption [Pantuck 2006]. This was supported by a study from Johns Hopkins which gave men with PSA progressive prostate cancer, pomegranate seed extract for 6 months. The PSAdt extended from 12 to 19 months and androgen levels in men did not change [Carducci 2011].
These laboratory and clinical studies have
confirmed that pomegranate has no androgenic or oestrogenic properties in the
laboratory or humans. A further study using high performance liquid
chromatography confirmed no steroid androgens or estrogens within pomegranates [Choi
2006]. The only potential issue was
a small study from Edinburgh which gave volunteers pomegranate juice daily.
After 2 weeks there was a significant reduction in blood pressure, elevation in
mood and lowering of anxiety but they also found that salivary testosterone
levels increased [Al-Dujaili 2012]. No explanation was given but as pomegranate
has no direct androgen activities this is likely to reflect a general
improvement in the metabolism and a reduction in stress, which is associated
with higher salivary testosterone [Hellhammer 1985].
Pomegranate, like many fruit juices, is a weak inhibitor of
cytochrome P450 (CYP2C9). There is, therefore, a small potential risk of
reducing the metabolism, and thereby increasing serum levels, of warfarin and
anti-hypertensives such as captopril, ramipril or anti-consulsants such a
carbimazole (for more details see; www.rxlist.com). Individuals on warfarin or
these blood pressure tablets are not excluded from taking Pomi-t and no adverse
changes in blood pressure or INR were reported in the Pomi-T study but it may be
advisable repeat a blood pressure and an INR test within two weeks of starting.
Our recommendation: Pomegranate (whole) extract combination
pomegranate can be pleasant and tasty but the seed contains more of the
anti-oxidants which is not absorbed if eating the fruit or drinking the juice
-taking a crushed seed extract supplement ensures a higher daily dose.. There
are many pomegranate extracts are available on the open market but it would be
advisable to take a tablet which has a good quality source of the whole fruit
with the sugar removed and has been combined with other anti-oxidant rich
a broad range of healthy plant based polyphenols and antioxidants within four

The whole food ingredients have been dried, concentrated then squeezed into a
tablet for a convenient way to boost daily intake. The rationale for combining
four different foods types (berry, vegetable, spice and leaf) was to provide a
wide spectrum of naturally healthy polyphenol nutrients, whilst at the same time
avoiding over-consumption of one particular type. Ingredients were also selected
to avoid foods with high phytoestrogenic or hormonal properties. Each
supplement tablets contains:
or caking agents:
Broccoli Powder 150mg
Turmeric Powder 150mg
Pomegranate seed powder 150mg
Green Tea 5:1 extract 30mg equivalent to 150mg
has been investigated in a UK Government approved national scientific
study which has the highest possible scientific design, the gold standard of all
trials - A double blind, randomised (RCT) placebo controlled trial. The study is
sponsored by the charity Prostate Action, has been adopted by the National
Cancer Research Network (NCRN), has UK Ethics Committee certification and is
independently audited to ensure adherence to European Good Clinical Practice
Guidelines (GCP). The chief investigator Professor Robert Thomas is Chair of
McMillan Survivorship Expert Advisory Committee and is a consultant Oncologist
at Bedford, Cranfield and Cambridge University Hospitals. The trial is currently
the world’s largest RCT of a food supplement to date and the full results will
be available in early 2013.
