Supplements to Be Cautious With If You Take Diabetes Meds (Safety First)

If you take diabetes medications, it’s smart to treat supplements like “real interventions,” not harmless add‑ons.

Some supplements may lower blood sugar, affect absorption of medications, or increase side effects—especially when stacked together.

## The big safety principle

If you add a supplement that can lower glucose on top of medications that lower glucose, the combined effect can increase the risk of hypoglycemia.

Extra caution if you use insulin or sulfonylureas.
