/ 5.0
Standardized Form
Cold-pressed Linseed Oil

Flaxseed oil is cold-pressed from flaxseeds and is one of the richest botanical sources of the omega-3 fatty acid alpha-linolenic acid (ALA). Unlike milled flaxseed powder, the oil contains no dietary fiber or lignans. The body must convert ALA into the active forms EPA and DHA; while this conversion rate is naturally very low (often under 5%), the ALA itself still provides systemic anti-inflammatory effects and supports lipid membrane integrity.

Clinical Summary

Supported by clinical evidence for improving symptoms of dry eye syndrome and modulating systemic inflammation markers.

Dosage Guidelines

1,000mg to 3,000mg daily.

Safety & Side Effects

Generally safe. Can cause mild gastrointestinal upset or loose stools at high doses.

Known Interactions

High doses may mildly increase bleeding risk when combined with oral anticoagulants.
