Can You Take MemoPryl With Thyroid Medicine?
MemoPryl with thyroid medicine is a combination to ask a doctor about first. Bacopa is one of the six names listed for MemoPryl, and a reference says it may raise thyroid hormone levels. No test of the finished capsule exists, and its amounts are not published.

The short answer01
Can you take MemoPryl with thyroid medicine?
MemoPryl with thyroid medicine should not be started without asking your doctor, because bacopa is among its six listed names. A clinical reference says people on thyroid hormone medicine should not take bacopa (Merck Manual, Bacopa).
Keep taking your prescribed thyroid pill exactly as directed while you ask. Never swap it for a supplement.
The reason02
Why does bacopa matter for the thyroid?
Bacopa matters for the thyroid because it may raise thyroid hormone levels. If you already take thyroid hormone, extra could push your levels past what your doctor planned (Merck Manual, Bacopa).
Small trials ran 12 weeks at 300 to 450 mg a day of bacopa extract (Pase 2012, Bacopa review). That is a research dose, not the MemoPryl amount, which is not published.
| Question | Research on bacopa | MemoPryl |
|---|---|---|
| Amount per day | 300 to 450 mg in 12-week trials (Pase 2012, Bacopa review) | Not published |
| Thyroid note | May raise thyroid hormone (Merck Manual, Bacopa) | No thyroid test found |
| Liver injury | Not linked in LiverTox (LiverTox, Bacopa) | Unknown |
Who should ask03
Who needs a doctor's advice before taking it?
Anyone who takes thyroid hormone, or has a thyroid condition, should ask a doctor before taking a capsule that lists bacopa. The same goes for people on blood thinners or other long-term medicines.
Bring the bottle. The six names are on the MemoPryl ingredients page, and a look-alike with a different formula needs its own check.
Reading the six names04
What else on the label needs a medicine check?
Most of the six listed names need some medicine check, not only bacopa. Filter the list by group and note which names touch your prescriptions.
- 1PhosphatidylserineNot published per serving · Not known
- 2Ginkgo biloba leafNot published per serving · Not known
- 3N-Acetyl L-Carnitine HClNot published per serving · Not known
- 4St. John's wortNot published per serving · Not known
- 5Brahmi / Bacopa monnieriNot published per serving · Not known
- 6L-glutamineNot published per serving · Not known
Names only: no amounts are published. Supplement labels must list each ingredient with its amount (21 CFR 101.36, supplement labels), so the bottle itself is the check.
If you still want to look05
Where do you see the current MemoPryl listing?

FAQ06
Questions about thyroid pills and herbal capsules
Does bacopa change levothyroxine or other thyroid pills?
A clinical reference says bacopa may raise thyroid hormone levels and that people on thyroid hormone medicine should not take it (Merck Manual, Bacopa). Ask your prescriber before adding it.
Should I tell my endocrinologist about herbal capsules?
Yes. Tell every provider about every supplement and keep a written list of names and reasons (NIH ODS, supplements basics). A thyroid specialist can then read your lab results with that in mind.
How soon before a thyroid blood test should I stop supplements?
There is no rule in our sources. Ask your doctor, who may want to know about any herb before a thyroid blood test, and keep taking your prescription meanwhile.
