The following are the ten best supplements for prostate health:
Sau đây là mười bổ sung tốt nhất cho sức khỏe tuyến tiền liệt:
1. Herbal remedies are regarded as some of the best prostate health supplements. Saw palmetto works to reduce the size of enlarged prostates and relieves urinary problems.
2. Nettle root is an effective natural supplement for prostate health. It reduces obstruction of urinary flow. Pygeum improves urinary symptoms associated with an enlarged prostate.
3. Red clover contains an antioxidant that fights cancerous growth. Red clover inhibits DHT (Dihydrotestosterone) formation.
4. Doses of vitamin C and vitamin B6 are also some of the best supplements for prostate health. They make urination easier and prevent swelling.
5. Another supplement for an enlarged prostate is soy (miso, soy milk) and fish oil. Selenium, found in brazil nuts, slows the progression of tumor growth.
6.Lycopene contains powerful antioxidants. Lycopene, found in red tomatoes and other tomato-based products (like ketchup and puree), is a natural supplement for prostate health.
7. Fruits like guavas, watermelon, and pink grapefruit act as natural supplements for prostate health. Fructose (the sugar found in fruits) stimulates the production of vitamin D that inhibits tumors.
8. Garlic, turmeric, ginger, and rosemary act as supplements for an enlarged prostate. Other enlarged prostate health supplements include skullcap, holy basil, and oregano.
9. Green tea (EGCG) may prevent prostate cancer by acting as a natural inhibitor of an enlarged prostate.

Medically known as benign prostatic hyperplasia (BPH), this condition eventually affects at least 80% of men and is most common after age 50. As the usually walnut-sized prostate grows, sometimes as big as a grapefruit, it presses on the urethra (the outflow tract from the bladder), causing incomplete emptying of the bladder, a weakened urine stream, the need to urinate frequently and urgently, and most notably, frequent bathroom breaks -- especially at night. While BPH is often more bothersome than dangerous, it can result in bladder and urinary tract infections or even kidney damage.
One in three men are treated for BPH with surgery or, more commonly, prescription drugs such as Flomax or Proscar. But growing research suggests that some symptoms may be treated as effectively with over-the-counter herbal remedies -- sometimes less expensively and thus far, with no reported side effects. What's more, some of these treatments claim they may help prevent prostate cancer, the second leading cause of cancer death in men.
"I don't want to give the impression that herbal solutions are better than traditional medications, but they definitely do have their place," says Aaron Katz, MD, director of The Center for Holistic Urology at Columbia-Presbyterian Medical Center. "In the past, the role of these herbal remedies has been overlooked by many. But there is now enough laboratory and clinical evidence to recommend their use in many patients with BPH and to maintain good overall prostate health."
Katz recently reviewed dozens of recent studies on various herbs used to treat BPH for a report in the December 2002 issue of The Journal of Alternative and Complementary Medicine. "While I would generally recommend pharmaceuticals to patients with more severe symptoms, these herbs can definitely improve mild to moderate BPH symptoms in many men," he tells WebMD.
Y tế được gọi là tăng sản tuyến tiền liệt lành tính (BPH), tình trạng này cuối cùng ảnh hưởng đến ít nhất 80% nam giới và thường gặp nhất sau 50 tuổi Khi tuyến tiền liệt thường là quả óc chó có kích thước lớn lên, đôi khi to như quả bưởi, nó ép vào niệu đạo (đường chảy ra từ bàng quang), làm rỗng không đầy đủ của bàng quang, một dòng nước tiểu yếu, sự cần thiết phải đi tiểu thường xuyên và khẩn trương, đáng chú ý nhất, phá vỡ phòng tắm thường xuyên - đặc biệt là vào ban đêm. Trong khi rầy nâu thường có nhiều khó chịu hơn so với nguy hiểm, nó có thể dẫn đến bàng quang và nhiễm trùng đường tiểu hoặc thậm chí tổn thương thận.
Một trong ba người đàn ông đang được điều trị bằng phẫu thuật hoặc rầy nâu, thường, thuốc theo toa như Flomax hoặc Proscar. Tuy nhiên, nghiên cứu phát triển cho thấy một số triệu chứng có thể được điều trị một cách hiệu quả với hơn-the-counter thảo dược - đôi khi ít tốn kém và do đó đến nay, không có tác dụng phụ được báo cáo. Hơn nữa, một số trong những phương pháp điều trị nói rằng họ có thể giúp ngăn ngừa ung thư tuyến tiền liệt, nguyên nhân thứ hai dẫn đến tử vong ung thư ở nam giới.
"Tôi không muốn tạo ra ấn tượng rằng các giải pháp thảo dược là tốt hơn so với thuốc truyền thống, nhưng họ chắc chắn không có vị trí của mình," Aaron Katz, MD, giám đốc của Trung tâm toàn diện tiết niệu tại Trung tâm Y tế Columbia-Presbyterian nói. "Trong quá khứ, vai trò của các thảo dược đã được bỏ qua bởi nhiều người. Nhưng bây giờ có đủ phòng thí nghiệm và bằng chứng lâm sàng để khuyến cáo sử dụng trong nhiều bệnh nhân bị rầy nâu và để duy trì tốt sức khỏe tuyến tiền liệt tổng thể."
Katz gần đây xem xét hàng chục nghiên cứu gần đây về các loại thảo mộc khác nhau được sử dụng để điều trị BPH cho một báo cáo trên số ra tháng 12 2002 của Tạp chí thay thế và Y Học Bổ Sung. "Trong khi tôi thường muốn giới thiệu dược phẩm cho bệnh nhân với các triệu chứng nghiêm trọng hơn, các loại thảo mộc có thể cải thiện các triệu chứng nhẹ rầy nâu đến trung bình trong nhiều người đàn ông," ông nói.
Saw palmetto is the leading herbal treatment for BPH and among the best selling of all herbal products, with annual U.S. sales of more than $25 million, according to the American Botanical Council. là điều trị hàng đầu thảo dược cho rầy nâu và một trong những bán chạy nhất của tất cả các sản phẩm thảo dược, với doanh số tại Mỹ hàng năm hơn 25 triệu USD, theo Hội đồng thực vật Mỹ.
"Saw palmetto is usually the first line of therapy against BPH -- at least by patients or their spouses," quips Franklin Lowe, MD, MPH, associate director of the Department of Urology at St. Luke's/Roosevelt Hospital and chairman of the American Urological Association's Complementary & Alternative Medicine Committee. "Most patients are taking it before they come to their urologist's office to find out if they should be taking it." Still, many urologists endorse it use for patients with early, troubling symptoms.
Pros: This herb brings relief in about one in three patients, with a suspected effect similar to Proscar, by blocking the production of a hormone that causes the prostate to grow. "Nobody really knows exactly why it works, because studies are conflicted on the suspected mechanism," says urologist Eric K. Seaman, MD, FACS. "What is clear is that it helps a lot of people, and there is no documented evidence of any side effects. I know a urologist who was waking up at least three times a night because of BPH, and since taking saw palmetto, he's up only once a night. So even if the majority of patients don't get a benefit, they don't lose anything either other than a few dollars."
Cons: One possible explanation for why the majority of patients don't get relief? The active ingredient of saw palmetto -- like its exact mechanism -- hasn't been identified, so different formulations may produce different results, says Katz.
Red clover has long been used as an alternative treatment for a variety of conditions -- from menopausal hot flashes to psoriasis -- because it is rich in isoflavones, a protein found in soybeans. Not only is this believed to help inhibit prostate and other cancer tumors, it could help treat BPH. A product commercially sold as Trinovin (and whose manufacturer paid for Katz's study) has been found in several trials to improve urine flow and decrease symptoms by as much as 23%.
Pros: Isoflavones are suspected of helping more than BPH, but Trinovin contains four types believed to be powerful for overall health and in treating BPH and reducing prostate cancer risk.
Cons: Some studies suggest that improvements are most noticeable after one month and then continue at a much slower rate. Little or no improvement is noticed at varying doses.
Soy contains high concentrations of the same isoflavones found in red clover and is often cited as a reason why Japanese men rarely get prostate cancer.
Pros: Also believed to offers many health benefits and strong evidence of reducing prostate cancer.
Cons: For maximum benefit, it's recommend that men consume eight ounces of soy foods daily, which is impractical and would create severe gas problems, says Katz.
African tree bark (pygeum africanum) is so popular in Europe and Africa that the tree from which this treatment is harvested is now on the endangered list.
Pros: Studies show it brings relief, but how? Some show it relieves symptoms by reducing prostate swelling, while others indicate it may reduce inflammation or inhibit growth factors associated with prostate enlargement and tumor development.
Cons: Typically not a standalone treatment, and usually used in conjunction with saw palmetto.
Of course, because they are not regulated by the FDA, some experts say that many herbal supplements vary widely in the amount of active herbal extract claimed on the label. A study presented to the American Urological Association last year found that some brands tested contained less than 15% of the active ingredient listed on their label.
Herbs for a Healthy Prostate
As men progress past the age of 50 years, the majority of them experience varying degrees of a condition known as benign prostatic hyperplasia, or BPH. BPH is a non-cancerous enlargement of the prostate gland. Because of the prostate gland’s location, enlargement can press on the structures around the urinary bladder and cause an increased frequency in the need to urinate, increased need to urinate at night (nocturia), decreased force and caliber of urine flow, and dribbling at the end of urination. Many men find these symptoms troubling enough to seek treatment.
Conventional treatments for BPH include drugs and surgery. Surgery may be necessary for severe prostate enlargement, to prevent urinary obstruction. However, for milder cases, alternative treatments are appealing because they lack the incidence of adverse events.
In many countries of the European Union, herbal supplements are the first-line, standard medical treatment for BPH. Although these herbs are available in the United States without a prescription, it is advisable that people with BPH use remedies, natural or otherwise, only under qualified medical care.
Saw Palmetto
Extracts of saw palmetto (Serenoa repens) berry are the leading natural treatment for BPH. Several clinical trials of saw palmetto have found the herb to be effective for mild-to-moderate BPH. A 1998 review of clinical trials of saw palmetto, published in the Journal of the American Medical Association, found that the herb improved BPH symptoms and urinary flow, providing benefits similar to those of finasteride (the most commonly prescribed drug for BPH), but with fewer side effects (Wilt et al, 1998). Studies previous to this definitive review were smaller, of shorter duration, and some had design flaws, but the efficacy of saw palmetto for BPH has been well-enough demonstrated for it to be recommended as a first line treatment for BPH by many urologists in the United States and Europe.
Saw palmetto appears to work by inhibiting an enzyme called 5-alpha-reductase, which is responsible for converting testosterone to its more active form, dihydrotestosterone (DHT). Saw palmetto also blocks DHT from binding in the prostate gland. Most studies have used 320 mg per day of saw palmetto extract that is standardized to contain approximately 80 to 95% fatty acids.
In 2006, the New England Journal of Medicine published a large, high-profile, negative study on the efficacy of saw palmetto for BPH (Bent et al, 2006) The findings of the study, however, are inconsistent with those of previous studies. What explains the discrepancy between the results of the NEJM study and those of previous studies? The authors had several theories: previous studies did not effectively mask the identity of the active and placebo formulations; the level of active ingredient in the extract was possibly insufficient to produce a measurable effect; and participants in theNEJM study may have had attributes that made them less likely to have a response to saw palmetto. The last point deserves special attention.
The participants in the NEJM study may indeed have had attributes that made them less likely to respond to saw palmetto. Previous studies found the herb effective for mild-to-moderate BPH. However, the NEJM study excludedmen with mild BPH and included men with severe BPH. It remains unclear why the researchers excluded those men most likely to be helped by the herb and included men least likely to be helped by it. But doing so casts serious doubt on their assertion that the symptoms of the participants in their trial “were similar to those of men in previous trials of herbs or pharmaceutical agents for benign prostatic hyperplasia.”
For the large part, the media reporting of this study was an uncritical echo of the dubious results, and saw palmetto’s deservedly good reputation has been harmed. Those who consider the totality of the research on saw palmetto will find that most of that research still supports the use of saw palmetto for mild-to-moderate BPH.
African Plum
Pygeum is an extract from the bark of an African tree, Pygeum africanum, or African Plum. Traditional African medicine included use of Pygeum bark to treat bladder disorders, particularly when those symptoms were associated with BPH.
The extract has been approved in Germany, France, and Italy as a medicine for BPH. Controlled clinical trials published over the past 25 years have shown that pygeum is safe and effective for men with mild-to-moderate BPH. In these studies, 50 to 100 mg of pygeum extract (standardized to contain 13% total sterols) twice per day has been the typical amount used. Pygeum has three main constituents which are thought to be responsible for its actions on the prostate: phytosterols, which are natural anti-inflammatory agents; triterpenes, which increase urination; and ferulic acid esters, which help balance cholesterol and prevent its accumulation in the prostate.
Stinging Nettle
Traditionally used by herbalists to treat asthma and rheumatism, concentrated extracts made from the roots of stinging nettle (Urtica dioica) have emerged as a well-documented, modern remedy for BPH. In a 1994 study, nettle extract was found to increase urinary volume and flow rate in men with early-stage BPH (Koch & Biber, 1994). It has been successfully combined with both saw palmetto and pygeum to treat BPH in double-blind clinical trials (Metzker et al, 1996). Stinging nettle has also been shown effective at relieving the severity of BPH and its symptoms when taken on its own (Safarinejad, 2005). Studies of nettle have typically used 120 mg of nettle root extract twice per day.
Other herbs and nutrients to consider include pumpkin seeds, beta-sitosterol, rye pollen extract, and certain amino acids (i.e., a combination of glycine, alanine and glutamic acid).
Get Physical
In addition to taking these herbal supplements, men with BPH (or who want to prevent it) are encouraged to remain physically active. Men who do so have a lower frequency of symptoms related to BPH in one study. Walking, the most prevalent activity among men, was related to a decreased risk of BPH (Platz et al, 1998). Men who exercise by walking two to three hours per week have a 25% lower risk of BPH compared with men who don’t use walking for exercise.
1) Saw Palmetto
In a report published in 2000, researchers reviewed 11 clinical trials and concluded that treatment with saw palmetto extract can help improve peak urinary flow rate and reduce patients' need to awake at night in order to urinate. However, a research review from 2009 deemed saw palmetto no more effective than placebo for treatment of BPH-related urinary symptoms.
2) Pygeum
Pygeum (a remedy sourced from the bark of the African plum tree) may be a useful treatment option for men with lower urinary symptoms resulting from BPH, according to a 2002 analysis of 18 clinical trials. However, the investigators caution that the reviewed studies were small in size, were of short duration, and used varied doses and preparations of pygeum.
