Primary Mechanism
Provides mucilage gums that increase fecal bulk and moisture while delivering anti-inflammatory systemic precursors
Standardized Form
Milled, ground, or cold-pressed powder

Flaxseed (Linum usitatissimum) provides a dual-action digestive benefit through its high mucilage (soluble fiber) content and structural insoluble fiber. It must be milled into a powder (or crushed) for the body to access its internal nutrients; whole flaxseeds pass through the digestive tract intact. Once milled, it delivers highly bioavailable omega-3 fatty acids (ALA) and phytoestrogen lignans (SDG), which offer mild anti-inflammatory properties alongside its gentle laxative effect.

Clinical Summary

Clinically utilized for supporting functional constipation, stabilizing blood glucose, and improving cardiovascular risk factors like high blood pressure.

Dosage Guidelines

10g to 30g (1 to 3 tablespoons) daily, mixed into foods or liquids.

Safety & Side Effects

Mild gastrointestinal discomfort, bloating, or increased bowel movements when first introduced.

Known Interactions

May decrease the absorption of certain oral medications if taken simultaneously due to high fiber content.
