Just an FYI, ALA (lipoic acid) may interfere with diabetes by lowering blood sugar (if you are diabetic and on meds, monitor your blood sugars and watch for low sugar (hypoglycemia).
ALA can also affect the thyroid and make thyroid supplements less effective. I take a thyroid supplement for hypothyroid (levothyroxine) and will be taking my new ALA at least 4 h after my thyroid meds. And I will likely have my TSH rechecked in 3-6mos to assure stable.
If anyone knows of other interactions, please share 😊
