Short answer: Glucomannan can affect the absorption of oral medication, so take any prescription at least an hour apart from your capsules — a direct, specific timing rule.
Why this rule is specifically flagged for diabetes and thyroid medication
This is particularly important for diabetes and thyroid medication, where chromium and green tea can also interact — a genuine, compounded concern beyond just the fiber-absorption issue alone.
Why "at least an hour apart" is a specific, actionable instruction
Rather than a vague "space them out" suggestion, this direct one-hour rule gives you something concrete to build into your daily schedule.
💊 Worth knowing: talk to your doctor first if you are taking medication for diabetes or thyroid conditions, or are on blood thinners.
