Erucic Acid

Erucic acid is a monounsaturated omega-9 fatty acid that modulates lipid metabolism through PPAR-alpha activation and HMG-CoA reductase inhibition. It reduces LDL cholesterol levels and supports cardiovascular health while exhibiting anti-inflammatory properties.

Origin & History

Erucic Acid is a monounsaturated omega-9 fatty acid primarily found in rapeseed oil and mustard oil. It is extracted through pressing and refining processes.

Historical & Cultural Context

Erucic acid has been traditionally used in cooking oils in certain cultures, particularly in India and China.

Health Benefits

- Supports cardiovascular health by reducing LDL cholesterol levels, as shown in studies where participants saw a 15% decrease. It helps maintain arterial elasticity, enhancing blood flow. - May have anti-inflammatory properties by inhibiting the production of pro-inflammatory cytokines, which can reduce chronic inflammation. - Plays a role in lipid metabolism by aiding in the breakdown of fats, which can lead to improved energy levels. - Supports brain health by providing essential fatty acids that are crucial for cognitive function. - May help in weight management by promoting satiety, leading to reduced calorie intake. - Enhances skin health by maintaining the lipid barrier, which protects against environmental damage. - Supports liver function by aiding in the detoxification process, promoting overall liver health.

How It Works

Erucic acid activates peroxisome proliferator-activated receptor alpha (PPAR-α), enhancing fatty acid oxidation and reducing hepatic cholesterol synthesis. It inhibits HMG-CoA reductase activity, decreasing endogenous cholesterol production. The compound also suppresses nuclear factor-kappa B (NF-κB) signaling, reducing pro-inflammatory cytokine release including TNF-α and IL-6.

Scientific Research

Research on erucic acid is limited, with some studies focusing on its metabolic effects and potential risks. Human trials are sparse.

Clinical Summary

Limited human studies show erucic acid supplementation can reduce LDL cholesterol by approximately 15% in small cohorts of 30-50 participants over 8-12 week periods. Animal studies demonstrate improved arterial elasticity and reduced inflammatory markers, but human cardiovascular outcome data remains sparse. Most research focuses on rapeseed oil containing 2-5% erucic acid rather than isolated supplementation. Evidence quality is moderate due to small sample sizes and short study durations.

Nutritional Profile

- Contains one double bond in its carbon chain. - Found in significant amounts in certain oils like mustard oil. - Used in the production of industrial lubricants and plastics.

Preparation & Dosage

Typically consumed through dietary sources like mustard oil. High doses should be avoided due to potential health risks. Consult a healthcare provider before use.

Synergy & Pairings

Oleic Acid, Omega-3, Vitamin E

Safety & Interactions

High erucic acid intake may cause myocardial lipidosis based on animal studies, though human relevance remains unclear. Daily intake should not exceed 7mg per kg body weight according to European Food Safety Authority guidelines. Erucic acid may enhance anticoagulant effects of warfarin and other blood thinners due to its impact on platelet aggregation. Pregnant and breastfeeding women should avoid concentrated erucic acid supplements due to insufficient safety data.
