I use a continuous glucose monitor and can confirm that it consistently reduces my blood sugar spikes after high-carb snacks by 40–50 points — truly impressive.

Good value multivitamin for diabetes support. Been using for 3 months and feel it helps. Only wish it came in a smaller tablet size as they're quite large to swallow.
