AssuriTEA helps relieve urinary symptoms in men

Go confidently

You knew your body would change with age. You expected hallmark changes like graying hair and an occasional backache, but you didn’t expect common urologic changes like having to use the bathroom more frequently or struggling to go due to a urinary stream that starts and stops.

As you’ve gotten older, you find yourself taking more bathroom breaks and rarely sleeping through the night without having to go. Sometimes you have a weak urine flow or experience difficulty urinating.

You’re not alone in experiencing these changes—one quarter of men in their 50s and one third of men in their 60s experience moderate to severe lower urinary tract symptoms (LUTS).3

AssuriTEA is a safe dietary supplement ingredient that helps support your urologic health as you age.

A safe, natural men's urologic health ingredient

AssuriTEA is a natural, tea-based polyphenolic blend with clinically relevant benefits for men’s urologic health, urinary function and comfort.4

The ingredient has been clinically studied in men with mild to moderate lower urinary tract symptoms (LUTS) and has been shown to support urologic health and function.1

In a 12-week study, men taking a daily dose of 1,000 mg AssuriTEA reported improvement in bladder emptying, urinary strength and flow, and nighttime urination after 6 or 12 weeks, compared to baseline.*

Natural, tea-based men's urologic health ingredient

Leveraging plant science to address men's health concerns

After identifying a consumer need for a natural urologic health supplement, we set out to develop a supplement ingredient to address urinary problems in men. Specifically, we wanted to identify a botanical solution for urinary problems in men, including frequent nighttime urination and uneven urinary flow.

Our scientists began at the molecular level—identifying catechins and theaflavins as key polyphenols with antioxidant properties.

After identifying the health benefits of green and black tea, we determined that tea (Camellia sinensis,L.) is a “botanical factory” for these key bioactives.

Because not all tea has the same molecular make up, we worked with our exclusive, dedicated tea supplier to screen and analyze thousands of lines of tea. Through this process we selected two non-GMO lines of tea—green and black—with optimal levels of polyphenols.

In order to deliver a select polyphenolic blend from the two lines of tea, our scientists developed a proprietary ratio to provide the most antioxidant benefits. These benefits have been clinically studied and suggest that AssuriTEA is a safe and natural solution for urinary control, function and comfort in men.

Tea ingredient with antioxidant and anti-inflammatory benefits

Carefully grown and gently extracted supplement ingredient

Our elite lines of tea are stringently grown on Rainforest Alliance Certified™ plantations. We work with dedicated farmers to hand pick tea leaves in short harvest cycles, maximizing the quality and levels of active molecules in each leaf.

The native molecular profile of our elite tea is extracted through a proprietary, gentle water extraction with no harsh solvents.


Clinically relevant benefits for men's urologic health

The men’s health benefits of AssuriTEA has been studied in two randomized double-blind, placebo-controlled trials. The results below are based on a 12-week, randomized, double-blind, placebo-controlled study during which men supplemented 1,000 mg of AssuriTEA daily.

Supplement ingredient that relieves lower urinary tract symptoms in men

Reduces lower urinary tract symptoms

Men who supplemented with AssuriTEA experienced fewer lower urinary tract symptoms compared to baseline after 12 weeks.1

These symptoms included incomplete bladder emptying, urinary stream intermittency, weak urinary stream and frequent nighttime urination.

Symptoms of LUTS were measured using the American Urological Association (AUA) symptom index.

Men taking AssuriTEA experienced a 34.5% decrease in AUA symptoms, a 6.1 point decrease versus baseline.

Supplement ingredient that helps men empty their bladders more easily

Improves bladder emptying

After six weeks of supplementation, the group taking AssuriTEA showed significantly lower levels of post-urination residual volume compared to baseline.1 Bladder emptying was measured with a bladder scan.  

Improve urine flow with supplement ingredient AssuriTEA

Improves urine flow

Men taking AssuriTEA experienced increased urine flow compared to the placebo group after 12 weeks.1


AssuriTEA helps reduce oxidative stress

The results below are based on a four-week, randomized, double-blind, placebo-controlled study during which three groups of men supplemented one of three doses of AssuriTEA daily.

Improves antioxidant capacity

Healthy men taking AssuriTEA had improved antioxidant capacity after four weeks.2

Antioxidant capacity in blood was measured by change of Ferric Reducing Ability of Plamsma (FRAP), and all doses significantly increased FRAP compared to the placebo group, demonstrating that AssuriTEA helps reduce oxidative stress.

Safe and tolerable, too

AssuriTEA is generally recognized as safe (GRAS) and has been shown to be well tolerated in all human clinical trials with no adverse side effects related to the study product.1,2,5
