Linseed (Linum usitatissimum) contains high levels of α-linolenic acid (ALA) at 51.9-55.2% of oil content and lignans including secoisolariciresinol diglucoside (SDG). ALA converts to EPA and DHA in the body, supporting cardiovascular health through anti-inflammatory mechanisms.
Origin & History
Linseed, also known as flaxseed, is derived from Linum usitatissimum, an herbaceous plant cultivated globally for its nutrient-dense seeds. The seeds are processed to extract oil or ground into powder, with linseed oil containing exceptionally high levels of α-linolenic acid (51.9-55.2%), making it one of the richest plant sources of omega-3 fatty acids.
Research Narrative (Provisional)
The provided research dossier lacks specific human clinical trials, randomized controlled trials, or meta-analyses with PMIDs. While the sources reference potential protection against cancer, diabetes, cardiovascular disease, and stroke, no detailed clinical trial data, study designs, or specific outcomes from human studies are available.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.

Reported Mechanism (Provisional)
α-linolenic acid (ALA) in linseed converts to EPA and DHA through desaturase and elongase enzymes, reducing inflammatory cytokines like IL-6 and TNF-α. Secoisolariciresinol diglucoside (SDG) lignans act as phytoestrogens, binding estrogen receptors and providing antioxidant activity through free radical scavenging. Phenolic compounds inhibit bacterial growth by disrupting cell membrane integrity.
Clinical Narrative (Provisional)
Small-scale studies (n=30-100) show linseed supplementation (15-30g daily) may reduce LDL cholesterol by 5-10% and systolic blood pressure by 2-5 mmHg over 8-12 weeks. Most evidence comes from mechanistic studies and animal models rather than large randomized controlled trials. Cardiovascular benefits appear modest and require consistent long-term intake. More robust human clinical data is needed to establish definitive therapeutic effects.
