Urolithin A is a compound some gut microbes can produce from ellagitannins found in foods such as pomegranates, nuts, and berries. Researchers are studying it in connection with mitochondrial health. Research on the ingredient does not establish results for this finished product.

Each labeled serving contains 500 mg Urolithin A, 100 mg CoQ10, and 100 mg trans-resveratrol. A serving is two vegan softgels. The bottle contains 45 servings.

Follow the serving directions on the product label: two softgels per serving. The label does not specify a particular time of day. Do not exceed the directions on the package.

Human studies have examined Urolithin A over short periods and in relatively small groups. A four-month trial in older adults found some changes in muscle endurance and blood biomarkers, while its primary six-minute-walk and muscle ATP outcomes did not improve significantly versus placebo. These ingredient studies do not prove that this product, or its added ingredients, produces the same results. Read the trial · Read the four-week study.

There is no established timeline for noticing a difference. Human studies measured outcomes over four weeks to four months, but that does not predict when—or whether—an individual will notice a change. Results are not guaranteed.

Each serving contains 100 mg CoQ10. CoQ10 is involved in normal cellular energy production. It is included as a companion ingredient; the finished WINYEL formula has not been shown in a clinical trial to produce a specific result.

Each serving contains 100 mg trans-resveratrol, a plant-derived polyphenol. It is included as a complementary ingredient, but the benefits of this specific combination have not been established in a clinical trial.

Short-term Urolithin A studies in adults reported generally favorable tolerability; one four-month trial found no significant difference in adverse events versus placebo. These studies cannot rule out rare or long-term effects and do not establish the safety of this exact finished formula for everyone. Ask a qualified healthcare professional before use if you take medication, have a health condition, are pregnant or nursing, or are preparing for surgery.

The softgel label shows vegan, gluten-free, non-GMO, and “LAB-TESTED” icons. It does not identify the certifying organizations or testing laboratory, test scope, or batch-specific results. Contact WINYEL to ask whether documentation is available for the batch you are considering.
