Key Benefits

  • The most potent fatty acid
  • Maintains gastrointestinal and vaginal flora
  • Vital to the absorption of nutrients, the elimination of waste, and proper immune function

 

Thorne’s Undecylenic Acid is the key to a healthy balance of gut flora. Maintaining a healthy balance of gut flora is a key component of overall health and is vital to the absorption of nutrients, the elimination of waste, and proper immune function. In women's health, the relationship of a healthy balance of gut flora has corresponding benefits for vaginal flora.

Studies going back 50 years demonstrate that fatty acids are effective in supporting a healthy gut flora. Undecylenic Acid is the most potent of the fatty acids – clinically shown to be effective in maintaining a healthy balance of gastrointestinal and vaginal flora. The undecylenic acid in Thorne’s Undecylenic Acid is six times more effective than caprylic acid. Its efficacy has helped make this product one of Thorne's best-selling products for more than two decades.
