This site states this specific caution directly: take thyroid medication. Bacopa may affect thyroid hormone levels.
Why this is listed as the first "talk to your doctor first" point
Worth noting this site places this specific interaction first among its five doctor-consultation points — worth reading that order as this site's own stated priority among its named cautions.
What to actually do about it
- Talk to your doctor before starting if you take thyroid medication
- Mention specifically that the formula contains Bacopa monnieri
- Never adjust prescribed thyroid medication dosage based on a supplement alone
- Have thyroid levels rechecked as your doctor normally recommends if you do start
💊 Medical note: Talk to your doctor before starting if you take thyroid medication, sedatives, or drugs that act on acetylcholine, if you have a mushroom allergy, stomach ulcer or slow heart rate, or if you are pregnant, nursing or under 18.
