Does tonic water with quinine affect thyroid stimulating hormone?

Tonic water contains quinine, which is generally consumed in small amounts. Current research does not indicate that tonic water or quinine significantly affects thyroid-stimulating hormone (TSH) levels. However, if consumed in excessive amounts or in individuals with specific medical conditions, it could potentially have effects due to its pharmacological properties. As always, it's best to consult with a healthcare professional for personalized advice.
