Brahmi is the Ayurvedic name for Bacopa monnieri, a small creeping herb. Trials of standardised extract taken daily for about 12 weeks report modest improvements on some memory and attention tests. The effect is not immediate, and stomach upset is the most common complaint. In parts of India the name brahmi is also used for a different plant, gotu kola.

| Focus and attention | Early | Results are mixed across studies and tests. |

Grades are our reading of published human trials on the ingredient, not tests of this product. Moderate: several controlled trials agree. Some: a few do. Early: small or preliminary. Traditional: long use, little trial data. None: nothing worth quoting. How we grade evidence
Taken from real searches in India.
For memory, there is some evidence. A 2014 analysis of nine randomised trials with 518 people found that Bacopa extract taken for at least 12 weeks improved speed of attention. The authors said a large head-to-head trial is still needed.
In a 12-week trial of 98 healthy people over 55, 300 mg a day of Bacopa extract improved verbal learning and delayed recall compared with placebo. Other memory measures in the same trial did not differ. The benefit is modest and specific.
About 12 weeks of daily use in the trials that found a benefit. It is not an exam-week supplement.
A few small studies have been done in children, but they are not enough to rely on. Do not give brahmi to a child without a paediatrician's advice.
Brahmi oil is a traditional hair application. There are no good human trials showing that taking brahmi improves hair.
No. Brahmi usually means Bacopa monnieri. Gotu kola is Centella asiatica, called mandukaparni in Ayurveda. Because both are sold as brahmi in different regions, check the botanical name on the label.
They are different herbs. Shankhpushpi is Convolvulus pluricaulis. Brahmi has considerably more human research behind it.
They are studied for different things: brahmi for memory, ashwagandha for stress and sleep. Choose by what you want it for.
They are often combined, and no harmful interaction is known, but the combination has not been well studied. Both can cause stomach upset.
Trials have used roughly 300 to 450 mg a day of standardised extract. Powder and vati tablets are different products with different amounts. Follow the label.
No trial has compared timings. Taking it with food reduces the chance of stomach upset.
Nausea, stomach cramps and more frequent bowel movements are the most reported. They were noticeably more common with Bacopa than with placebo in trials.
Animal studies suggest Bacopa may raise thyroid hormone levels, so people with thyroid conditions should check with a doctor. There is no good human evidence of liver or kidney harm at studied doses, but data is limited.
Often because of the test method. UV measurement reads a much higher figure than HPLC on the same extract. A percentage without a method tells you little.
