Undecylenic Acid is designed to help maintain a healthy balance of flora in both the gastrointestinal and vaginal tracts, which is essential for overall well-being. Each gelcap provides 250 mg of undecylenic acid, a compound clinically shown to support the optimal functioning of the GI tract by promoting efficient absorption of nutrients, elimination of waste, and strengthening immune function.
Particularly beneficial for women, as it helps maintain the delicate balance of gut flora, which directly correlates with maintaining healthy vaginal flora. Such balance can be challenged by factors like an unhealthy diet, the use of oral contraceptives, or taking various medications.

Thorne is a trusted name in supplements, collaborating with the Mayo Clinic and supporting over 100 professional teams, including U.S. Olympic Teams. These relationships underscore the company's commitment to quality and efficacy.

The product comes in a convenient package of 250 gelcaps, offering 50 servings.
