Scientific Evidence for ProstaStream
What is ProstaStream?
The supplement uses several ingredients to target prostate issues, including saw palmetto berries, Graviola extract, mushroom extract, and tomato fruit powder. The formula also contains zinc and copper, both of which are linked with prostate health.
By taking ProstaStream daily, you can purportedly target prostate symptoms and relieve symptoms of benign prostate hyperplasia (BPH). Prosta Stream makers claim their formula targets the severe inflammation that causes an enlarged prostate supplement in the first place.
The company also claims their formula is “the only all-natural clinically proven supplement” that addresses the root cause of the prostate enlargement, helping you sleep through the night and pee just three times per day.
How Does ProstaStream Work?
ProstaStream contains a blend of dozens of herbal extracts and plant extracts mixed with vitamins and minerals. However, only a few of these ingredients are found in a large enough dose to impact the body significantly.
Key ingredients in ProstaStream include zinc, selenium, copper, saw palmetto berries, plant sterol complex, and Pygeum africanum bark. Although the formula contains dozens of other ingredients, none of the doses seem large enough to impact human health.
Most prostate support supplements contain similar ingredients. In fact, you can find similar ingredients in a $10 multivitamin. Zinc and copper are linked with prostate health, and studies show that some men with prostate issues have low zinc levels. Zinc is found in particularly high concentrations within the prostate, and getting your recommended daily intake of zinc could support a healthy prostate.
Plant sterol complex is also linked with prostate health. Although known as beta-sitosterol, plant sterols are natural plant substances found in fruits, vegetables, nuts, and seeds.
As WebMD explains, beta-sitosterol (i.e., plant sterols) are “most commonly used for lowering cholesterol levels and improving symptoms of an enlarged prostate (benign prostatic hyperplasia or BPH).”
Many major studies have linked plant sterols to improved symptoms of an enlarged prostate. Studies show that taking 60 to 130mg of beta-sitosterol by mouth per day can improve symptoms of BPH.
However, the makers of ProstaStream claim their supplement does even more than that: they claim their supplement targets inflammation that causes the enlarged prostate in the first place. Studies have shown that plant sterols do not actually shrink an enlarged prostate, although it could help with certain prostate symptoms.
Overall, the only ingredients worth mentioning in ProstaStream are zinc, copper, and plant sterols. These three ingredients are linked with prostate health in various ways – although they can also be found in much cheaper prostate support supplements.
ProstaStream Ingredients
ProstaStream contains dozens of plant extracts, vitamins, and minerals. As mentioned above, however, most of these ingredients are in dosages too low to significantly impact the body in any way.
ProstaStream contains a normal dose of vitamin E, vitamin B6, zinc, selenium, copper, saw palmetto, and plant sterol complex, although most other ingredients are found at dosages of 10mg to 50mg.
Prosta Stream has just 10mg of maitake mushroom extract, for example. Typically, studies use a dose of 50mg to 500mg of maitake mushroom extract.
These ingredients may complement the effectiveness of ProstaStream by targeting inflammation throughout your body. Many of these ingredients are adaptogens (like the mushroom extracts) or rich with antioxidants (like the fruit extracts). However, the dosages seem lower than other supplements – especially given the $50 to $70 bottle price range.
The full list of ingredients in Prosta Stream include vitamin E, vitamin B6, zinc, selenium, copper, saw palmetto berries, plant sterol complex, Pygeum africanum bark, red raspberry fruit, Annona muricata leaf, green tea leaf, cat’s claw bark, broccoli leaf stems and buds, tomato fruit, stinging nettle leaf, maitake mushroom, reishi mushroom, shiitake mushroom, and a proprietary blend containing quercetin dihydrate, juniper berry, uva ursi leaf, buchu leaf, L-glutamic acid, L-alanine, L-glycine, calcium D-glucarate, pumpkin seed, burdock root, cayenne pepper fruit, goldenseal root, gravel root, and marshmallow root.
All ingredients are packaged into a bovine gelatin capsule with rice flour, silicon dioxide, and magnesium stearate used as binders, fillers, and preservatives.
Scientific Evidence for ProstaStream
Prosta Stream makers have not run any clinical trials on their formula, nor have they published any scientific studies involving humans or animals. Instead, the company cites just five studies on its “References” page as proof Prosta Stream works as advertised.
The company also cites this page from Harvard Health, showing how doctors treat enlarged prostates. As explained by that page, doctors typically prescribe 5-alpha reductase inhibitors (5-ARIs) that shrink the prostate gland to improve urinary flow. The FDA has approved two 5-ARI drugs for enlarged prostates, including Proscar (finasteride) and Avodart (dutasteride). Again, Prosta Stream is not a drug, nor does it contain any drug ingredients.
“Experts disagree on whether saw palmetto improves men's symptoms of BPH. Experts also don't clearly understand how saw palmetto may improve symptoms of BPH. It might stop the growth of the prostate or even make it smaller.”
The University of Michigan page cites some studies showing that saw palmetto reduced prostate symptoms. However, other studies had no observed changes in urine flow or nighttime urination compared to a placebo.
Finally, the company cites this 2016 study published in the Indian Journal of Clinical Biochemistry, showing that zinc, copper, iron, calcium, and selenium were linked with prostate cancer. Researchers examined prostate cancer cells and their chemical makeup, concluding that there was a “complex relationship between trace elements and prostate carcinogenesis.”
In other words, none of the referenced studies show significant evidence Prosta Stream works as advertised.
Who’s Behind ProstaStream?
ProstaStream is marketed online by a company named BuyGoods. BuyGoods sells several nutritional supplements and health eBooks online, although the company has a reputation for selling overpriced supplements and providing over-hyped health advice.
Final Word
ProstaStream is a nutritional supplement that claims to relieve symptoms of an enlarged prostate by targeting inflammation. The supplement contains fruit extracts, plant extracts, vitamins, and minerals that could support prostate health in various ways.
Unfortunately, there’s limited research ProstaStream works as advertised. The supplement contains low doses of most ingredients. Like zinc and beta-sitosterol, the most–proven ingredients can be found in much cheaper prostate supplements from more reputable retailers.
