Supplementation with spirulina in a standard anti-diabetic regimen
Parikh et al. · 2001 · Journal of Medicinal Food
Key finding
Spirulina added to standard anti-diabetic therapy significantly reduced fasting blood glucose and postprandial blood glucose. HbA1c fell by 1% over 12 weeks — a clinically significant reduction.
Why this matters for consumers
HbA1c reduction of 1% is meaningful by clinical standards. This was achieved as an add-on to existing treatment, not as a replacement — an important distinction for safety-conscious readers.
Study limitations
Standard anti-diabetic medication varied between participants; small sample; single-centre.
