“Natural” does not mean risk-free. Ingredients can have biological effects, interact with medicines, and affect people differently.
Who should take extra care?
People taking prescription medicines, people with chronic conditions, pregnant or breastfeeding people, and people preparing for surgery should discuss supplements with an appropriate healthcare professional.
Medication interactions
If a supplement is marketed around blood sugar, people already using glucose-lowering medicines should not assume the combination is harmless. A pharmacist can help screen ingredient lists for known interactions.
Report serious problems
Seek medical care for serious symptoms. In the United States, consumers and clinicians can also report adverse events involving FDA-regulated products through FDA safety reporting channels.
