Galactomannans are the most effective soluble dietary fibers in type 2 diabetes: a systematic review and network meta-analysis
The American journal of clinical nutrition (2023) · Meta analysis · n=2685
Galactomannans had the highest effect on reducing the levels of HbA1c (SUCRA: 92.33%) and fasting blood glucose (SUCRA: 85.92%).
Meta-analysis showed 17.24 mg/dL reduction in fasting glucose with stronger effects above 200 mcg/day. Effects primarily demonstrated in type 2 diabetes patients. Chromium picolinate shows higher bioavailability than other forms.
Meta-analysis showed modest weight loss of -0.97 kg but with considerable heterogeneity (I2: 73%). Combined fiber study showed larger effect but included other fibers alongside inulin.
