Tetradecylthioacetic acid (TTA) is a synthetic fatty acid used as a nutritional supplement.

TTA acts as a peroxisome proliferator-activated receptor alpha (PPARα) agonist and increases mitochondrial fatty acid oxidation in vitro.[1] In rodent studies, TTA has been reported to have other activities such as reducing inflammation[2] and preventing high fat diet induced adiposity and insulin resistance.[3]

In human clinical study, there have been mixed observations in preliminary studies. One Phase I study showed no significant changes in the blood lipids or free fatty acids[4] and another showed that TTA attenuates dyslipidemia in patients with type 2 diabetes mellitus.[1]
