Can I take Fibre supplements and Metformin together?

Why this happens

Fibre supplements (like psyllium husk or glucomannan) work by soaking up water and forming a gel in your gut. This gel can trap the metformin molecules, slowing down or reducing the amount of medicine that passes through your intestinal wall into your bloodstream.

What you should do

You do not need to stop taking either, but it is best to separate the doses. Try to take your metformin at least 2 hours before or 4 to 6 hours after taking a fibre supplement. Always monitor your blood sugar levels regularly and speak to your doctor if you notice your readings are consistently higher than usual.
