Natural Flaxseed Powder 10% Lignans
Linum usitatissimum seed brings a whole family of lignans, and secoisolariciresinol diglucoside is the one that anchors this grade. We hold it at 10% and confirm the load by HPLC, giving formulators a fixed figure to build a formula around. The powder is pale, fine and free-flowing, wets out readily in water-based systems, and sits at the economical end of a range that climbs to 80%. Cyanogen testing belongs in every batch record here, not in an optional add-on list.

Function & Formulation Fit
Lignan Carrying Base
Delivers a consistent SDG load into capsules and tablets, keeping the dose steady across lots.
Clean Powder Flow
An 80 mesh grain moves through dosing equipment without bridging or separating in blends.
Water Dispersion
Hydrates in aqueous systems, opening drink powders and fermented dairy bases to the grade.
Fermentation Friendly
A seed-derived lignan source that sits comfortably alongside fibre and probiotic components.
Application Fields
Two-Piece Capsules
The highest-volume home for 10% material, where a declared marker beats a higher assay on price.
Breakfast Cereals
Blends into flake and granola recipes that want a seed lignan source without changing texture.
Sachet & Stick Packs
Works in single-serve dry mixes where a 40% extract would load the formula too heavily.
Alt-Milk & Yogurt Style
Carries a plant lignan component into dairy-free bases without disturbing the emulsion.
Meal-Replacement Blends
Fits multi-ingredient nutritional powders as one botanical component among several.
