Benign prostatic hyperplasia (BPH), defined as the enlargement or swelling of the prostate gland, is one of the most common health problems faced by men. Over 50% of men age 50 and over suffer from BPH, and almost 100% of men over the age of 80 can expect to develop this condition. (1) Prostate enlargement and symptoms of BPH are influenced by hormonal, inflammatory, and nutritional factors. (1)
Androgens (male hormones) play a critical role in the development of BPH. Specifically, dihydrotestosterone (DHT), the active metabolite of testosterone, causes the prostate gland to enlarge. (1) Beta-sitosterol is a plant sterol that supports healthy prostate function. It works by inhibiting the enzyme 5-alpha reductase that is responsible for converting testosterone to DHT. (2) A six-month placebo-controlled trial of men with BPH found that supplementation with 130 mg of beta-sitosterol per day significantly improved international prostate symptom scores (IPSS) by 51%, compared with only 19% for the placebo. Supplementation also improved measures of quality of life, peak urinary flow rate, and post-void residual urinary volume. (3)
Pygeum (Pygeum africanum) bark and stinging nettle (Urtica dioica) root extracts are additional sources of beta-sitosterol that have been used successfully to reduce symptoms of BPH, such as weak urine flow and incomplete voiding of urine. (2,4) A review of 18 controlled clinical trials found that men taking Pygeum extract were more than twice as likely as placebo groups to experience improved BPH symptoms. Overall, the studies found that Pygeum reduced nocturia by 19%, reduced residual urine volume by 24%, and increased peak urine flow by 23%. (5)
A six-month placebo-controlled trial found that 81% of BPH patients who were supplemented with 360 mg of stinging nettle extract per day had improved lower urinary tract symptoms compared to 16% of the placebo group. Patients experienced a 77% improvement in peak urine flow rates and a modest reduction in prostate size. (4) Vitamin D3 intake is positively associated with a lower rate of BPH because of its role in inhibiting the hormonal aspects of its development. Preclinical trials have demonstrated that supplementation with vitamin D3 can also help decrease existing BPH cell growth. (6)
Inflammation contributes to the development of BPH and at chronic levels may progress BPH to the stage of disease. (1) Ultimate Prostate combines multiple antioxidant and anti-inflammatory ingredients, including lycopene, selenium, rosemary extract, and rye pollen. (2) Carnosol and carnosic acid, the main antioxidant compounds in rosemary, have been demonstrated through animal studies to provide an anticarcinogenic influence on prostate cells. (7)
Pollen extract is a mixture of natural anti-inflammatory compounds that inhibit the synthesis of signalling molecules and mediators of inflammation. Supplementation has been shown to improve quality of life and reduce pain in patients affected by chronic pelvic pain syndrome and chronic prostate inflammation. (2)
Eating a diet rich in fruits and vegetables provides the nutrients lycopene and zinc, which are critical to protecting overall prostate health. (2) Cruciferous vegetables, such as broccoli, are particularly important sources of the anti-carcinogenic compounds indole- 3-carbinol and sulforaphane, which help protect against prostate disease. (8).
BioPerine® black pepper extract is standardized to 95% piperine, an active alkaloid that improves the bioavailability of nutrients that may otherwise be difficult to absorb. (9)

When should I start taking a prostate formula?The most beneficial age to start the formula would be in a man's early 30's, but really – it’s never too late to start! Can you tell me a bit more about your prostate formula?
Ultimate Prostate™ is a nutritional product designed to offer a highly effective, yet natural solution to on-going prostate problems and optimal support of prostate health. The synergistic ingredients within the formula are scientifically documented to help protect the prostate gland from becoming enlarged, to help reduce the swelling of the prostate, help protect the prostate from cancer and to help to optimize the overall health of the prostate gland.Why do you not use saw palmetto in your Ultimate Prostate™ formula?Actually, beta sitosterol is an active ingredient in saw palmetto - which works to block the conversion of testosterone to dihydrotestosterone (DHT) via its inhibition of the enzyme "5-alpha reductase". The daily recommended dosage of 3 capsules of Ultimate Prostate™ includes 300mg of pure (non GMO) phytosterols standardized to 45% beta sitosterol (135mg). I already take a prostate formula, but I like the sounds of yours. Can I switch? If so, should the switch be gradual?
Yes, you can easily switch to the Ultimate Prostate™ no matter how old you are or how long you have been taking your other formula. The switch from one prostate formula to Ultimate Prostate can be immediate (as opposed to gradual), as the active ingredients in this complete and effective formula go to work immediately.Once I notice a difference and am feeling better, do I stop taking this product?It is important to continue taking Ultimate Prostate™, even after prostate symptoms have improved, as this will help ensure continual prostate health.
Is Ultimate Prostate gluten free?
Yes, we do have confirmation on file that there is no gluten added and no gluten present in Ultimate Prostate. However, our manufacturing facility is NOT a gluten free facility, and as we do process products that contain gluten we are unable to confirm 100% that there is no possibility of cross contamination.
Are Brad King's products WADA certified?
No, we do not have an official WADA (World Anti-Doping Agency) designation or release on our Ultimate products by Brad King.I have noticed that many of Brad King's products contain an ingredient called "Bioperine Black Pepper Extract". What exactly is this?This black pepper is not the same as pure black pepper. It is actually a standardized extract from the fruit of black pepper (containing 95% piperine). It is used in the majority of the Ultimate products to increase the bio-availability of the nutrients within these formulas. Bioperine is the only source from piperine to have undergone clinical studies in the U.S. to substantiate its complete safety and research-proven efficacy for nutritional use. Many individuals have difficulty absorbing and utilizing nutrients within nutritional formulas. The Ultimate products insure that people are not only getting the best formulas possible, but that they are actually absorbing and utilizing what they are paying for.
Do all of your products have an NPN?
Yes, all of our products have been issued a Natural Product Number (NPN) by Health Canada – these numbers do appear on our labels. Further Natural Health Product criteria and information can be found on the Health Canada website www.hc-sc.gc.ca Under the Food and Drugs Act items that are considered a food – for example, our protein powders and herbal teas – do not require an NPN. Are your capsules GMO free?
Yes, our vegetarian capsule shells, our gelatin capsule shells and our softgel shells are all non-GMO.Are your products GMO free?
Preferred Nutrition is currently in the process of testing all of our products so that we can advise the public if any of them contain ingredients that come from genetically modified organisms or not. Once the testing is complete we will indicate on our website, as well as on our product information sheets and on our labels. This will be done as quickly as possible and on a product-by-product basis.Why have your cautions and your recommended/suggested usages changed so dramatically on many of your labels?
The changes you are noticing to our suggested usage and cautionary statements have been at the directive of Health Canada. There have been many regulatory changes with regards to Natural Health Products causing companies to change their labels accordingly. We update our website, product information sheets and labels on the actual products to reflect these regulations as quickly as we possibly can. Health Canada and the industry representing natural health products act according to the interest of consumers and their safety. As a result, if there is any concern with an existing condition, a caution is added to advise the consumer to seek out feedback from their Health Care professional. Will this product help me lose weight?
There is no such thing as a "magic" pill or product - the only way to succeed (and maintain) true weight loss is by adopting a healthy lifestyle combining adequate exercise and proper nutrition. If you are concerned about poor eating habits or cravings, then we recommend you seek advice from a Nutritionist or Naturopath to obtain some guidance on healthy eating, as well as to investigate possible underlying (or undiagnosed) hormonal imbalances, which can make it harder to lose weight. You might also want to consider speaking with a personal trainer to help you discover a fun fitness program that you enjoy - because, no matter what, in order to achieve and maintain any type of weight loss, exercise is required. Our vitamins and supplements are designed to help you in your quest to a daily, healthy lifestyle, however it also requires effort on your part.Where do you source your products from?
Please be advised that all of our ingredients, including flavourings, are derived from natural ingredients and are ISURA tested & certified (in order to ensure the absence of GMOs, contaminants, heavy metals and adulteration). All of our products are manufactured at a GMP facility certified by Health Canada. All raw materials come in and are tested for purity, safety and potency. If they do not meet our standards they are rejected and sent back or destroyed. We use the highest quality ingredients available, and choose organic whenever we can. Many of our products contain proprietary patented ingredients that have been clinically researched to help deliver optimal results and outstanding quality.Are your products peanut free?
Following compliance with food regulations, in order to make a negative claim such as "peanut free", it would be necessary to insure a zero tolerance of any peanut traces, including the possibility of cross contamination. Although our manufacturing facility has a policy in place for allergen control, there is no specific policy for peanuts, nor is there a specific "no peanut agreement" with our raw material suppliers.Can your products be used after the expiry date has passed?
Supplements generally keep their potency long after the expiry date. There is certainly no safety issues with consuming after the expiry date has passed however the potency degrades over longer periods of time.If a product does not specify "vegetarian capsule", then what is it made from?
These capsules are gelatin capsules sourced from either pork or beef.Are any of your products "vegan-friendly"?
Yes, AdrenaSense, EstroSense, MenoSense, BioSil, Medi-C Plus, Magnesium and MagSense (from our WomenSense and Preferred Nutrition product lines), the Healing Teas, our Ultimate Maca Energy products and the Ultimate VEGAN line are all vegan friendly.
Why can't I find any prices on your website?
Preferred Nutrition is the wholesale distribution company for the products on this website. However we sell exclusively to Health Food stores & selected Natural Pharmacies across Canada, not directly to the general public. Because the prices of our products can vary from store-to-store, we are unable to list our suggested prices on our website. We recommend you contact your local retailer and inquire about prices directly with them. Can I purchase products directly from you? I went to a health food store and the prices seem very expensive.
We distribute our products in Canada only and we sell directly to Health Food stores - since they have a personal commitment to the natural health lifestyle. Consumers are then able to buy our products from knowledgeable staff that are genuinely interested in helping people be well - people who care! Always be sure to look for in store promotions or coupons when you are making your purchases as this can help alleviate your cost concerns.Do all health food stores carry all of your products?
To find Health Food stores in your area that carry our products, please click on "Store Locator" at the top of this screen. All you have to do is enter your postal code and you will be given a list of retailers in the radius that you choose. We do recommend calling ahead to see if they stock the item you are looking for and in most cases if a store does not normally carry something, they will offer to do a special order for you.Are any of your products tested on animals?
No, there is no animal testing on any of our products.Should your supplements be taken with or without food?
Most of our products will specify directly on the bottle whether they should be taken with a meal or not. If nothing is stated, then the choice is yours as to when the best time is for you to take them. In general, however, most vitamin supplements should be taken with food because once eating starts the digestive process, enzymes and gastric juices are generated and usually the nutrients will be absorbed and assimilated better.I like the sound of many of your products. Am I able to take different formulas at the same time?
Yes, it's safe to combine various WomenSense products to help support the body in achieving optimal health. The same applies to the Preferred Nutrition line, Dr. Whitaker's formulas and Brad King's. If you are unsure of any combination, then please consult your Health Care Practitioner.I have heard that drinking green tea along with my supplements will end up flushing out all the nutrients? Is this true?
No, you are fine taking your supplements with green tea. Coffee inhibits the absorption of nutrients, but the caffeine in green tea will not pose the same problem.Can you tell me if I can combine any of your supplements with the medication(s) I am on, as prescribed by my doctor?
It is best to consult your Doctor or alternative Health Practitioner before taking any new supplements while on prescribed medication. If you have been approved to add our supplement(s) to your daily regime, then we do recommend that you space the medication and the supplements out by at least one hour.I understand that you put a recommended dosage on your labels, but I can take more or less than that, right? And, really, do I have to take the product every day?
With regards to the recommended dosage, we would suggest you speak to your Doctor or Health Care Practitioner before increasing any amounts. As with any supplement you can determine your amount based on your personal preference - if you find that a product works for you immediately then you should be fine to take it just on the days you feel you need it, but again we suggest you discuss this with you MD or HP. Some consumers find that a product needs to be in their system for a few days to a few weeks before they notice results and/or feel the full benefits. I don't understand why when I purchase your product and open the bottle, the contents don't even fill 1/2 of the packaging that is being used?
The containers we use are determined based on product fill and required label information, as well as capsule count when/where applicable. Sometimes we do have to use a larger bottle than seems necessary because of the information required on the labels - requirements both from Health Canada and in order for the label to be clear and legible to our consumers. Also, in a case where we are offering larger volume (ie/ 400g versus 200g or 180 capsules versus 90 capsules), then we have to put the contents in a bigger container in order for there to be differentiation on the shelf.I bought a bottle of your product, and although it seemed to feel lighter than usual, I didn't think much of it, until I opened the bottle and discovered that there is nowhere near the amount of capsules inside as there should have been. How can this happen?
As part of our corporate policy and Good Manufacturing Practices (GMP) requirement, our procedures incorporate routine in-process checks plus a final examination of the finished product to ensure conformance to all aspects of quality, including correct product count. There are a number of checks and balances performed by both Production and Quality Assurance personnel prior to, during, and after the packaging operations to ensure that product under-counts do not happen. Although product under-counts can happen, this occurrence is rare. Should you discover that your bottle is far below the label claim count upon opening - we recommend you return it to your point of purchase as per our 100% customer satisfaction guarantee.What is your 100% money-back (customer satisfaction) guarantee?
Our 100% money-back/customer satisfaction guarantee ensures that if a customer is not completely satisfied with their purchase, they can return the unused portion of the product (in its original packaging) back to their point of purchase and we will credit the Health Food store 100% of their purchase price from us. We cannot dictate if a store will give cash back or an in-store credit, nor can we override store policies already in place ~ but we do promise to credit them, regardless of the reason for the return.
