Pomegranate contains large amounts of polyphenols called punicalagins. Punicalagins have a broad spectrum of effects, including promoting prostate health, acting as a natural Viagra, and even inhibiting carbohydrate absorption.*
- Promotes healthy prostate size and function*
- Supports healthy hormone metabolism in the prostate*
- Increases testosterone*
- Decreases Estrogen*
- Decrease DHT*
- Promotes better blood flow to the penis*
- Decreases carbohydrate absorption*
Pomegranate punicalagins are polyphenols primarily in pomegranate root, bark, and leaves that support the male reproductive system.
Once punicalagins enter your gastrointestinal tract, they convert into ellagic acid and urolithins, which enter the bloodstream efficiently through the colon. So, pomegranate punicalagin supplementation delivers high circulating ellagic acid and urolithins as active pomegranate metabolites.
How Do Pomegranate Metabolites Work?
- Blocking Testosterone Conversion to Estrogen: Punicalagin metabolites are potent aromatase inhibitors, preventing testosterone from converting to estrogen and substantially elevating testosterone naturally. A study of men and women found that pomegranate punicalagins raise the hormone 24%.
- Blocking Testosterone Conversion to DHT: Punicalagin metabolites inhibit the 5-alpha reductase enzyme, preventing testosterone from converting to DHT and increasing testosterone.
- Promoting Stronger Erections: Punicalagin metabolites elevate nitric oxide (NO), which relaxes the smooth muscle fibers of the penile arteries, allowing more blood to flow into the organ.
- Supporting Blood-Vessel Health: Studies show punicalagin metabolites enhance circulation and support arterial health.
- Preventing Carbohydrate Absorption: Punicalagin metabolites inhibit alpha glucoside, which decreases glucose absorption.
How Do I Get Pomegranate Punicalagins?
Unfortunately, you can't just eat pomegranates or drink the juice to get these effects. That's because punicalagins are mainly in the root, bark, and leaves, none of which go into making commercial pomegranate juice.
Effective punicalagin supplementation comes from quality pomegranate extracts. An effective dose is 100 mg or more. Look for labels that show the actual punicalagin content.

- Kroeger N et al. Pomegranate Extracts in the Management of Men's Urologic Health: Scientific Rationale and Preclinical and Clinical Data. Evid Based Complement Alternat Med. 2013 Mar 26. Abstract: Numerous micronutrients and polyphenols found in soy, green tea, and many fruits and vegetables have been described to impact diseases including erectile dysfunction, benign prostatic hyperplasia, and prostate cancer. However, oftentimes these reports lack both a scientific rationale and supportive evidence base. The efficacy of pomegranate, on the other hand, in the modulation of central biological processes like inflammation, hypoxia, and oxidative stress that are important in the pathogenesis of urological maladies has been robustly demonstrated in preclinical in vitro and in vivo studies. Moreover, clinical trials have further supported its use in the treatment of several diseases, in particular in the management of prostate cancer.

Int J Impot Res. Nov-Dec 2007;19(6):564-7. Abstract: This randomized-controlled trial examined the efficacy of wonderful variety pomegranate juice versus placebo in improving erections in 53 completed subjects with mild to moderate erectile dysfunction. The crossover design consisted of two 4-week treatment periods separated by a 2-week washout. Efficacy was assessed using International Index of Erectile Function (IIEF) and Global Assessment Questionnaires (GAQ). Of the 42 subjects who demonstrated improvement in GAQ scores after beverage consumption, 25 reported improvement after drinking pomegranate juice. Further, 17 subjects showed preference of one beverage to the other. Subjects were more likely to have improved scores when pomegranate juice was consumed (P=0.058).

- Gur S et al. Characterisation of pomegranate juice effects on human corpus cavernosum. Andrologia 2017 Oct;49(8). Abstract: This study evaluates the molecular characterisation and confirmation of POM's action on human corpus cavernosum (HCC) obtained from patients (n = 16) undergoing penile prosthesis implantation. We conclude that POM induced marked relaxation of HCC via: (i) nNOS stimulation, and (ii) downstream relaxation stimulated by nNOS and cGMP and bypassing the NO and PDE5. This action provides a rationale for the therapeutic or preventative use of POM in men with erectile dysfunction who do not respond well to PDE5 inhibitors.

- Deng Y et al. The extract from Punica granatum (pomegranate) peel induces apoptosis and impairs metastasis in prostate cancer cells. Biomed Pharmacother. 2017 Se9;93:976-984. Abstract: This study aimed to investigate the effects of pomegranate peel extract (PoPx) on the apoptosis and metastasis of prostate cancer cells and the related mechanism. They found that PoPx showed growth inhibition on prostate cancer cells. Nuclei morphological and flow cytometer (FCM) analysis indicated that PoPx could induce prostate cancer apoptosis. Wound healing assay and transwell migration and invasion assay implied that PoPx has the potential to inhibit migration and invasion, two critical steps in prostate cancer metastasis. Downregulation of MMP2/MMP9 and upregulation of TIMP2 showed accordance with the inhibition of migration and invasion. In summary, the present data showed that PoPx could be a promising drug candidate to treat prostate cancer, showing us a better way to develop novel drugs from natural compounds.

- Chrubasik-Hausman S et al. Pomegranate juice and prostate cancer: importance of the characterisation of the active principle. Phytoter Res. 2014 Nov;28(11):1676-8. Abstract: Two exploratory clinical studies investigating proprietary pomegranate products showed a trend of effectiveness in increasing prostate-specific antigen doubling time in patients with prostate cancer. A recent clinical study did not support these results. We therefore analysed a lot of the marketed pomegranate blend for co-active pomegranate compounds. The results show that the co-active compounds in the daily dose of the pomegranate blend were far below those previously tested and that the photometric assessment is not reliable for the standardisation of study medications. Not pomegranate but the low amount of co-active compounds in the proprietary pomegranate blend was responsible for its clinical ineffectiveness.
- Wang L et al. Pomegranate and Its Components as Alternative Treatment for Prostate Cancer Int J Mol Sci. 2014 Sep; 15 (9):14949-14966. Abstract: Recent research has shown that pomegranate juice (PJ) and/or pomegranate extracts (PE) significantly inhibit the growth of prostate cancer cells in culture. In preclinical murine models, PJ and/or PE inhibit growth and angiogenesis of prostate tumors. More recently, it has been shown that three components of PJ, luteolin, ellagic acid and punicic acid together, have similar inhibitory effects on prostate cancer growth, angiogenesis and metastasis. Results from clinical trials are also promising. PJ and/or PE significantly prolonged the prostate specific antigen (PSA) doubling time in patients with prostate cancer.
- Amri Z et al. Growth Inhibitory and Pro-Apoptotic Effects of Ornamental Pomegranate Extracts in Du145 Human Prostate Cancer Cells. Nutrition and Cancer. Volume 72. 2020. Issue 6. Abstract: This study was aimed to investigate the influence of dwarf pomegranate extracts (peel, juice, and seeds oil) on the proliferation and apoptosis of human prostate androgen-independent cell line DU145. The three tested extracts exhibited a dose-response cytotoxic effect and antiproliferative action on DU145 cell line and induce morphological changes. The three extracts could also induce prostate cancer cell apoptosis by an increase of DNA fragmentation, PARP cleavage, and inhibition of the COX-2 expression. The strongest pro-apoptotic effect was shown after peel treatment.
