Big effect
A three-month trial found 16g of flaxseed daily slashed HbA1c and other metabolic markers in type 2 diabetes — but the results come from a single, early-stage study in a specific population, so handle with caution.
This is one of the first controlled trials to show a clear, large effect of flaxseed on multiple diabetes-related blood markers, but because it's so new and limited to Mexican adults with type 2 diabetes, it's a promising clue rather than a settled fact.
Glycated hemoglobin (HbA1c) reflects average blood sugar over the prior two to three months — a key number for diabetes management. In this study, 16 grams of ground flaxseed each day for three months led to significant drops in HbA1c, fasting glucose, total cholesterol, and triglycerides. That's a strong signal, but it's early evidence from a single clinical group, so don't read it as a universal prescription.
Where this fits in the evidence
This is among the first studies we've indexed on flaxseed for Reduced Glycated Hemoglobin — treat it as an early signal until more research accumulates.
