Common effects01
What are the most common bacopa side effects?
The most common bacopa side effects are stomach upset, nausea and dry mouth. A liver-safety reference lists them as minor and usually short-lived, with rates close to placebo in trials (LiverTox, Bacopa).
The same source also lists gas, diarrhea, headache, dizziness, insomnia and rash.
| Group | Effects |
|---|---|
| Most reported | Stomach upset, nausea, dry mouth (Merck Manual, Bacopa) |
| Less often | Gas, diarrhea, headache, dizziness (LiverTox, Bacopa) |
| Rare or unclear | Insomnia, rash (LiverTox, Bacopa) |
Liver and thyroid02
Can bacopa harm your liver or thyroid?
Bacopa has not been linked to liver injury, but it may raise thyroid hormone levels. People who take thyroid hormone medicine should not use it (Merck Manual, Bacopa).
It may also change blood levels of medicines handled by liver enzymes, warfarin among them. Keep taking prescribed medicine and ask your doctor or pharmacist before trying bacopa.
Before you start03
How can you check a bacopa capsule before taking it?
Check a bacopa capsule by reading the label, matching the names and showing it to a pharmacist. Bacopa is also called brahmi.
- 01
Read the bottle first
This site has no Supplement Facts panel. When the bottle arrives, read its serving size, every ingredient name and the warnings before the first capsule.
- 02
Match it to the six names
The brief names phosphatidylserine, ginkgo, N-Acetyl L-Carnitine, St. John's wort, bacopa and L-glutamine. If your panel lists other ingredients, it is a different formula.
- 03
Show it to your pharmacist
Put the bottle next to your medicine list. St. John's wort and ginkgo are the two names that most often matter.
- 04
Note a start date and check in
Write down the date and how you feel about memory and focus. If the signs of memory trouble grow, see a doctor instead of waiting out a bottle.

FAQ05
Bacopa safety questions
Does bacopa make you sleepy or keep you awake?
Sources list insomnia as a possible effect, and none of our sources list sleepiness (LiverTox, Bacopa). Responses vary. If your sleep changes after you start, note the time of your capsule and tell a pharmacist.
Can bacopa upset your stomach on an empty stomach?
Stomach upset and nausea are its most reported effects (Merck Manual, Bacopa). Our sources give no rule about food. Ask a pharmacist whether taking it with a meal makes sense for you.
Is bacopa safe for people with thyroid problems?
Not without medical advice. Bacopa may raise thyroid hormone levels, and people taking thyroid hormone medicine should not take it (Merck Manual, Bacopa). Carry on with prescribed medicine and ask your doctor first.
