Bacopa Monnieri in Neuro Recall: Modest Trial Results, the Dose Gap and Side Effects
Quick answer
Bacopa monnieri is an Ayurvedic herb, sold as an extract measured by its bacosides. Small trials in healthy adults using 300 to 450 mg a day for 12 weeks or more found modest gains in attention speed and some recall tests. Neuro Recall does not print how much bacopa its 635 mg blend holds. Stomach upset is the most common side effect.
What is bacopa monnieri?
Bacopa monnieri is an herb from Ayurveda, the traditional medicine of India. Supplements use an extract of the whole plant, measured by its bacosides, the plant compounds that extracts are standardized to.

- What NLT means
- Not less than: at least 20% of the extract is bacosides
- Amount in Neuro Recall

- Studied dose
- 300 to 450 mg of extract a day
- Studied length
- 12 weeks or more
Bacopa is one of only three Neuro Recall blend ingredients with small, early studies behind it, alongside L-theanine and lutein with zeaxanthin. That makes it worth a careful look, including at what the trials did not show.
How is bacopa thought to work?
The sources we read do not pin down how bacopa acts in the brain. What the trials do show is a timing pattern: any effect seems to build over weeks of daily use, not within hours.
A single 300 mg dose had no clear effect after 2 hours, while trials of about 300 mg a day for 12 weeks found gains in some memory and processing measures (Rejuvenation Res 2013, Aguiar and Borowski, Bacopa review). That is the opposite of a coffee-style lift. The track below shows how a typical trial unfolds.
- Day 1
One dose
A single 300 mg dose showed no clear effect after 2 hours.
- Weeks 1 to 11
Daily use
Trials gave the extract every day. Our sources report no results before week 12.
- Week 12
First measurements
Trials of 12 weeks or more found faster attention and some recall gains.
- Beyond
The unknown
Long-term human safety has not been studied.

What did studies of bacopa find?
Small trials in healthy adults found modest gains, mostly in attention speed and in free recall, which means remembering items without hints. Every review we read calls the evidence early and asks for larger, better trials.
| Review | Who was studied | What it found |
|---|---|---|
| Meta-analysis, 2014 (J Ethnopharmacol 2014, Bacopa meta-analysis of RCTs) | 9 trials, 518 people, 12 weeks or longer | Faster scores on a timed attention test and on choice reaction time; the clearest effect was on attention speed |
| Systematic review, 2012 (J Altern Complement Med 2012, Bacopa systematic review) | 6 trials of adults without dementia, 300 to 450 mg a day, 12 weeks | Better scores on 9 of 17 free recall tests; little evidence for other thinking skills |
| Aguiar and Borowski, 2013 (Rejuvenation Res 2013, Aguiar and Borowski, Bacopa review) | Trials of 46, 76 and 81 adults, including ages 40 to 65 and older Australians | Gains in some memory and processing measures at about 300 mg a day |
The 2012 authors said bacopa research is "in its infancy". The 2014 team said a large, well-designed trial is still needed before anyone can call the evidence definitive, in healthy people or in dementia.
How much bacopa is in Neuro Recall compared with the studied dose?
The label does not say. Neuro Recall prints only the 635 mg total for its ten-ingredient blend. Simple arithmetic still shows the amount is very likely below the lowest dose used in trials.
| Measure | Amount |
|---|---|
| Lowest daily dose in the trials | 300 mg of extract |
| Share of the blend 300 mg would take | About 47% of 635 mg |
| An even split of the blend | About 63.5 mg, roughly a fifth of 300 mg |
| The most bacopa could be, if listed by weight | About 159 mg, a quarter of the blend |
| Bacoside strength in one trial | 55% |
| Bacoside strength on this label | At least 20% |
| Bacopa in Neuro Recall | Not published |
Why a quarter? FDA rules ask a blend to list its ingredients from most to least by weight (FDA, Dietary Supplement Labeling Guide, Ch. IV). Bacopa is fourth, after cinnamon, ginkgo and bilberry. If the label follows that rule, each of those three weighs at least as much as bacopa, so bacopa cannot be more than 635 divided by 4, about 159 mg. That is about half of the lowest trial dose.
The strength gap matters too. One 12-week trial used an extract with 55% bacosides; this label promises at least 20% and prints no exact figure. See how bacopa compares with the other 13 ingredients in the Neuro Recall ingredients guide, and why ginkgo's trial looked so different on the ginkgo page.
What are the side effects of bacopa?
The side effects reported most often in people are nausea, faster movement of the gut, and stomach and bowel upset (Rejuvenation Res 2013, Aguiar and Borowski, Bacopa review). Long-term human safety studies have not been done.
| Question | What the sources say |
|---|---|
| Most common side effects | Nausea, increased gut movement, stomach and bowel upset |
| Long-term safety | Not studied in people; trials ran about 12 weeks |
| Drug interactions | Not covered by the sources we read; that is a gap, not proof of safety |
| Pregnancy and nursing | No bacopa data in our sources; the Neuro Recall label says do not use |
Other ingredients in the same capsule do carry known interactions, mainly ginkgo with blood thinners. That is covered in our article on ginkgo, bacopa and blood thinners, and every label ingredient's side effects are on the Neuro Recall side effects page.
Who should avoid bacopa, or ask a doctor first?
Skip bacopa, and Neuro Recall, if you are pregnant, nursing or under 18. Check with a doctor first if you take prescription medicine or have a sensitive gut. Your answers stay on this page.

Do you have a stomach or bowel condition that flares easily?
Are your memory problems new, getting worse, or worrying people close to you?
Answer every question to see your result. Nothing is saved or sent.
No flags from these questions. If you try it, give it at least 12 weeks, as the trials did, and watch your stomach.

Bacopa monnieri: questions people ask
What does bacopa do for the body?
In small trials of healthy adults taking 300 to 450 mg a day for 12 weeks or more, attention speed got faster and some recall tests improved. How it acts in the body is not settled in our sources.
Does bacopa help memory?
Modestly, in small trials. A 2012 review found better scores on 9 of 17 free recall tests, and its authors called the research early.
How long does bacopa take to work?
Trials measured results after 12 weeks or more of daily use. A single 300 mg dose had no clear effect after 2 hours.
How much bacopa per day?
Trials used 300 to 450 mg of standardized extract a day, most often 300 mg. Neuro Recall does not print its bacopa amount.
What are bacopa side effects?
Nausea, faster gut movement, and stomach and bowel upset are the most common in people.
What is the best time to take bacopa?
No trial in our sources compared times of day, and the Neuro Recall label names none. Pick a time you will keep every day.
Is bacopa safe long term?
Nobody knows yet. Trials ran about 12 weeks, and long-term human safety studies have not been done.
What is bacopa extract good for?
It is studied for attention and recall in healthy adults, with modest results. It is not a treatment for memory loss or dementia.
How much bacopa is in Neuro Recall?
Not published. Bacopa is one of ten ingredients sharing a 635 mg blend, and the label prints only the total.
