About Linseed
Whole flaxseed supplies ALA (omega-3), lignans (SDG) and soluble fiber. Multiple meta-analyses of RCTs show modest blood-pressure reduction (~4-5 mmHg systolic in hypertensive/at-risk subjects) and small LDL/total-cholesterol reductions, generally with ground seed at 15-30 g/day over 12+ weeks. Effects are real but modest and heterogeneous; whole seed outperforms oil for lignan/fiber effects. Not a substitute for a dedicated omega-3.
What Linseed supports
- May modestly lower blood pressure in at-risk adults
- Source of plant omega-3 (ALA) and soluble fiber
How much Linseed to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
10–30
g
Whole/ground seed doses used in cardiovascular RCTs (typ. 15-30 g/day). Blend components usually list far less as presence-only.
Clinical evidence
Moderate clinical evidence. Meta-analyses of RCTs show modest BP and lipid benefit at 15-30 g/day.
