Rye PollenSkip to the navigation
Pollen, a substance collected from the flowers of various plants, contains carbohydrates, fat, protein, and some vitamins and minerals.1 Rye pollen has been the best studied for its potential clinical uses.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Benign Prostatic Hyperplasia
126 mg three times daily
Rye pollen extract has been shown to improve BHP symptoms.
Rye pollen extract has improved the symptoms of BPH in preliminary trials.1 , 2 , 3 Double-blind trials have also reported that rye pollen extract is effective for reducing symptoms of BPH4 , 5 This rye pollen extract was shown to be comparable in effect to an amino acid mixture used for BPH in a double-blind study.6 A double-blind comparison with pygeum resulted in significant subjective improvement in 78% of those given the rye pollen extract compared with 55% using pygeum.7 Research on this commercial rye pollen extract has used three to six tablets, or four capsules, per day; the effect of other pollens in men with prostate conditions has not yet been studied.
Two tablets of flower pollen extract twice per day
An extract of flower pollen, derived primarily from rye, may improve symptoms of chronic prostatitis and prostadynia.
An extract of flower pollen, derived primarily from rye, may improve symptoms of chronic prostatitis and prostadynia. In a small, uncontrolled trial, men with chronic NBP or prostadynia given two tablets of flower pollen extract twice daily for up to 18 months reported complete or marked improvement in symptoms.8 In a larger, uncontrolled trial, one tablet three times daily for six months produced a favorable response in 80% of the men based on symptoms, laboratory tests, and doctor evaluations.9 Men who did not respond in this study were found to have structural abnormalities of the urinary tract, suggesting that uncomplicated prostate conditions are more likely to respond to flower pollen. Additional uncontrolled studies support the effectiveness of flower pollen extract,10 , 11 , 12 but no controlled research has been published.
How It Works
How to Use It
Research on a proprietary rye pollen extract has used 3 to 6 tablets, or 4 capsules, per day.
Where to Find It
Most noncultivated plants produce pollen. Commercial pollen is collected from bees returning to their hives (bee pollen) or may be directly harvested with machines (flower pollen). It is not clear which plants produce the most effective pollens. In addition to rye, other common pollens used are timothy grass, corn, and pine.
Since pollen is not an essential bodily constituent, deficiencies do not occur.
Interactions with Supplements, Foods, & Other Compounds
Interactions with Medicines
Many people have allergies to inhaled pollens. Allergic reactions to ingested pollen (some of them quite serious) have also been reported.2 3 4 Otherwise, no significant adverse effects have been reported.
