What do the states mean?+
- Solid: well studied, and it works.
- Half-there: the science is still forming.
- A ghost: almost no real studies.
- Hollow: well studied, and it does not work.
- A cord: the pair itself has been tested together.
- Air: nobody has ever tested this pair.
The full scoring method: How we score
Can you take ashwagandha and Bacopa monnieri together?
Nobody has tested this pair.
As of August 2026, no human trial has given ashwagandha and Bacopa monnieri together. We searched PubMed for trials naming both on 26 August 2026 and read every candidate it returned; none tested the pair.
24 studies · none tested the actual pair · 2 cautions

What you’re seeing
- Ashwagandha renders solid: for stress and anxiety, it is well studied and it works.
- Bacopa monnieri renders half-there: for memory and focus, the science is still forming.
- Nothing is drawn between them, because nothing has been run. The empty space is the review.
You can tell before you read a word.
Vitamin D + vitamin K2 is what the other answer looks like. Someone ran the study, so a cord is drawn between them. That is the whole difference.
Fair questions
Is it safe to take ashwagandha and Bacopa monnieri together?+
No trial has tested the combination, so there is no evidence either way. Nobody has found a problem, and nobody has looked.
Why does this page say nobody has tested it?+
Because we ran the search and read the results. The date above is the day we ran it. We do not claim a pair is untested without a logged search behind it.
Will this page change?+
Yes, if a trial publishes. We re-run these searches and the page changes from air to a cord the day the evidence does.
Deeper
The search we ran+
On 26 August 2026 we asked PubMed for trials, reviews and meta-analyses naming both ashwagandha and Bacopa monnieri. It returned 3 candidates. We read every one and none gave the two together. This page carries a date because the answer can change: if a trial publishes, the air becomes a cord.

Pairs that have been tested+
- Ashwagandha has been tested with ginger, black pepper.
- Bacopa monnieri has been tested with Ginkgo biloba.
These are the combinations someone has actually run a study on. Every other pairing here is air.
Worth knowing+
- Ashwagandha reads consistently positive here, but its literature is small (136 human supplementation papers, against 4,000 for magnesium) and most trials use proprietary standardised extracts supplied by their manufacturers. The direction of the evidence is real. Its independence is not established.
- Ashwagandha: The meta-analysis behind the sleep claim adds a warning we should carry: data on serious side effects from ashwagandha are limited, so nobody can yet say whether long-term use is safe. Separately, reviews of ashwagandha flag it as unsuitable in pregnancy.
