Tetradecylthioacetic Acid for Health & Longevity - Quick Reference Sheet

Tetradecylthioacetic Acid for Health & Longevity

Created on 08/01/2026 – Quick Reference based on Evidence Review created using AI4L / Opus 4.8 Audit

A lab-made fatty acid the body cannot burn, so it acts as a lasting signal that switches on fat-burning genes and calms inflammation. Small, short human studies modestly lowered bad cholesterol and triglycerides but did not improve blood sugar or weight. Safety data are brief, supply is unregulated, and long-term value remains unproven. (Full Review)

Schedule
Single daily dose
No advantage to splitting doses
Time to effect
Blood lipids
~4 weeks
LDL and triglyceride changes emerge
Inflammation
~4 weeks
Inflammatory markers decline
First week
No change
No lipid effect after 7 days

Benefits

Contraindications
  • Pregnancy or breastfeeding
  • Active liver disease (Child-Pugh B or C)
  • Significant kidney impairment (eGFR <30 mL/min/1.73 m²)
  • Symptomatic gallbladder disease
  • History of statin- or fibrate-induced muscle injury
  • Unable to arrange basic lab monitoring
Key Interactions
  • Statins (atorvastatin, simvastatin, rosuvastatin)
  • Other fibrates (fenofibrate, gemfibrozil)
  • Warfarin and other blood thinners
  • Blood-sugar-lowering drugs (sulfonylureas such as glipizide; insulin)
  • NSAIDs (ibuprofen), niacin
  • Additive lipid supplements (omega-3, red yeast rice, berberine, garlic)
  • Other strong PPAR agonists

Risk & Side Effects

  • High: [risks_high]
  • Medium: [risks_medium]
  • Low: Mild gastrointestinal and general adverse events; depletion of beneficial omega-3 fats
  • Speculative: Liver enzyme elevation; muscle toxicity; gallstones, kidney marker rises, and homocysteine increases; rodent liver tumors

Monitoring

Marker Target Why
LDL cholesterol <100 mg/dL Primary efficacy target; TTA's clearest human effect
Triglycerides <100 mg/dL Storage-fat marker responsive to TTA
HDL and LDL/HDL ratio HDL >50 mg/dL; LDL/HDL <2.0 Captures the ratio improvement seen in trials
ALT and AST (liver enzymes) ALT <25 U/L (men) / <20 U/L (women); AST <25 U/L Detects class-based liver stress
Creatine kinase (CK) 30–150 U/L Detects muscle toxicity, especially with statins
Creatinine and eGFR eGFR >90 mL/min/1.73 m² Class agents can raise creatinine
Fasting glucose and HbA1c Glucose 70–90 mg/dL; HbA1c <5.4% Confirms no adverse glucose effect
hs-CRP (inflammation) <1.0 mg/L Tracks the anti-inflammatory signal
Omega-3 index (EPA + DHA) >8% of red-cell fatty acids TTA depletes omega-3s; guides fish-oil pairing

Cadence: Baseline, then ~4 weeks, ~12 weeks, then every 3–6 months

Qualitative Assessment

  • Energy levels and exercise tolerance
  • Appetite and any changes in body composition
  • Skin or joint inflammation
  • General well-being and absence of muscle pain or upper-right abdominal discomfort
