oleic acid
Oleic acid is a monounsaturated omega-9 fatty acid commonly found in olive oil, nuts, and various seeds. It functions as an anti-inflammatory compound that modulates cellular signaling pathways including PI3K/AKT-Nrf2 and AMPK-mTOR, affecting lipid metabolism, insulin sensitivity, and oxidative stress. Oleic acid is used primarily for metabolic health, cardiovascular protection, and anti-inflammatory purposes.
Lab Notes — Research Studies
01 Dietary oleic acid supplementation and blood inflammatory markers: a systematic review and meta-analysis of randomized controlled trials
Meta-analysis of 31 RCTs involving 1,634 subjects found that oleic acid supplementation significantly reduced C-reactive protein (CRP) levels, indicating anti-inflammatory benefits, though it did not significantly affect other inflammatory markers like TNF or IL-6.
View Study ((PubMed))02 Oleic acid abomasal infusion limits lipolysis and improves insulin sensitivity in adipose tissue from periparturient dairy cows
Oleic acid infusion reduced adipose tissue lipolysis and improved insulin sensitivity in dairy cows during the periparturient period, suggesting beneficial effects on metabolic regulation and energy balance.
View Study ((PubMed))03 Oleic acid ameliorates amyloidosis in cellular and mouse models of Alzheimer's disease
Oleic acid supplementation reduced amyloid-beta levels and BACE enzyme activity in Alzheimer's disease models, decreased amyloid plaques, and increased non-amyloidogenic APP processing, suggesting neuroprotective effects.
View Study ((PubMed))04 Free Linoleic Acid and Oleic Acid Reduce Fat Digestion and Absorption In Vivo as Potent Pancreatic Lipase Inhibitors Derived from Sesame Meal
Oleic acid demonstrated potent pancreatic lipase inhibitory activity with an IC50 of 11.7 µg/mL and significantly suppressed fat digestion and absorption in rats, suggesting potential for weight management applications.
View Study ((PubMed))05 Dietary oleic acid intake increases the proportion of type 1 and 2X muscle fibers in mice
Dietary oleic acid supplementation increased the proportion of slow-twitch type 1 and oxidative type 2X muscle fibers in mice, suggesting potential benefits for endurance and metabolic muscle characteristics.
View Study ((PubMed))06 Nitro-oleic acid regulates growth factor-induced differentiation of bone marrow-derived macrophages
Nitro-oleic acid, a metabolite of oleic acid, was found to regulate macrophage differentiation and modulate immune responses, demonstrating anti-inflammatory properties in bone marrow-derived cells.
View Study ((PubMed))07 Hesperetin ameliorates hepatic oxidative stress and inflammation via the PI3K/AKT-Nrf2-ARE pathway in oleic acid-induced HepG2 cells and a rat model of high-fat diet-induced NAFLD
Study used oleic acid to induce hepatic steatosis models, demonstrating its role in fatty liver research and establishing that interventions targeting oxidative stress pathways can ameliorate oleic acid-induced liver damage.
View Study ((PubMed))08 Dehydroepiandrosterone alleviates oleic acid-induced lipid metabolism disorders through activation of AMPK-mTOR signal pathway in primary chicken hepatocytes
Research utilized oleic acid to model lipid metabolism disorders in hepatocytes, demonstrating that interventions activating AMPK-mTOR pathways can reverse oleic acid-induced metabolic disturbances.

⚠️ Side Effects
- Cellular Stress: At high concentrations, oleic acid can induce hepatic steatosis and lipid accumulation in cell models
- Metabolic Disruption: Excessive intake may contribute to lipid metabolism disorders in susceptible individuals
- Research Safety: Human trials generally report good tolerability when consumed as part of balanced dietary fats
- Limited Standalone Data: Few reports of side effects from isolated oleic acid supplementation in humans
📦 Availability & Sourcing
- Food Sources: Readily available through olive oil (55-85% oleic acid), avocados, nuts (especially macadamias and almonds)
- Supplement Form: Not commonly sold as isolated oleic acid supplement; typically consumed through dietary sources or mixed fatty acid products
- Research Grade: Available as research chemical for laboratory use but not marketed for human supplementation
Reaction Log — User Experiences
Oleic acid receives minimal direct discussion in user forums as a standalone supplement, appearing primarily in research contexts and as a component of other supplements. When mentioned, it's generally recognized for anti-inflammatory properties but lacks substantial user experience data for assessment.
