Overview

Clinical Summary

TTA (tetradecylthioacetic acid) is a modified fatty acid studied for lipid metabolism effects through PPAR-related signaling. It is used for triglyceride and fatty acid oxidation claims, with limited clinical validation.

Early research suggests possible triglyceride reductions and increased fatty acid oxidation, with evidence from small human and animal studies. Some work suggests reduced liver fat and inflammation biomarkers in experimental settings. Minority claims include improved insulin sensitivity and mitochondrial function, with limited data. Long-term safety and efficacy remain insufficiently established, limiting confidence in net benefit.

Non-metabolizable fatty acid analog that activates PPAR-alpha, upregulating lipid metabolism genes and driving fat oxidation in peripheral tissues without providing caloric energy itself.

Outcomes

What This Is Expected To Influence

Primary Outcomes

  • Modest reduction in plasma triglycerides and free fatty acids in one small human RCT (T2D patients).

Secondary Outcomes

  • Minor fat loss in human subjects over short periods, though far less dramatic than rodent data suggests.

Population: Men with Type 2 Diabetes

Dose protocol: Source-listed

Key findings: TTA reduced plasma lipids and free fatty acids, demonstrating a shift toward increased fat oxidation. Weight loss was minor but statistically significant vs placebo.

Population: Patients with mild to moderate psoriasis.

Dose protocol: TTA 1000 mg/day for 28 days.

Key findings: Improvements in cholesterol parameters and reductions in inflammatory cytokines in psoriasis patients.

Notes: Small pilot study in psoriasis population. One of the only additional human trials of TTA, confirming biological activity consistent with PPAR-alpha agonism.

Paper content

This small double-blind, placebo-controlled pilot study tested TTA (tetradecylthioacetic acid) at 1000 mg/day for 28 days in patients with mild to moderate psoriasis. The study found improvements in cholesterol parameters and reductions in inflammatory cytokines. While not a supplementation study in the traditional sense, this is one of the only human trials of TTA and provides direct evidence of biological activity in humans. The psoriasis context and small sample size limit generalizability, but the lipid and inflammatory biomarker changes are consistent with TTA's PPAR-alpha activation mechanism.
