Pomegranate studies (real ones) have been uneven in results. One study found no overall benefit, but did find a benefit for men with a certain genotype (who were about
25% of the subjects). So it's possible
some men can benefit from a substance even if all men do not.
I took Pomi-T for two years (a supplement with some good results developed specifically for a British double-blind, placebo-controlled, randomized study and then commercialized), but found I could get a more of its four ingredients much cheaper by buying individual capsules of the them (broccoli extract, pomegranate, tumeric, and green tea extract).
Of interest to me in recent years is that a couple of studies have found a synergistic effect when two different supplements were taken in combination. So the whole may be greater than the sum of its parts..
For anyone seriously interested in phytochemicals for possible PCa protection, I strongly recommend the published trials and in vitro studies medical literature and not ads. A good starting place is the NIH's
Prostate Cancer, Nutrition, and Dietary Supplements (PDQ®)–Health Professional Version (2020)
It summarizes the evidence for the more popular supplements and is updated a couple of time a year. There is a link to a less technical Patient Version. PDQs are available on several aspects of PCa -- Screening, Treatment, Genetics and Genomics, etc. -- all of which are kept updated.
Pay attention to what the literature says about
recommended dosages. Most phytochemical are generally safe in the suggested dosages (these are naturally occuring food substances). Some,however, like, lyc
opene, can be toxic if you take too much. Some supplements that have been touted over the years have not demonstrated a benetif in trials. A serious handicap in our knowledge of phytochemicals is that big pharma has no interest in proving this or that compound in a food has a beneficial effect. So we have to rely on studies financed by governments and private institutions -- and we know what the $ story is there.
I am not endorsing the taking of anything -- rather if you are interested, make decisions based on the best evidence. The purported benefits of many phytochemicals, e.g., reservatrol, go well beyond PCa.
