New York, New York: Americans are spending billions of dollars every year on brain supplements, memory pills, and so-called nootropics. They line the shelves of every pharmacy, big-box store, and health food shop in the country. The ads promise sharper memory, faster thinking, and a mind that doesn't slow down with age. What those glossy labels won't tell you is what licensed clinical psychologist and author Dr. Patricia A. Farrell wants every consumer to know: for most healthy adults, the science simply doesn't back up the sales pitch.
In her new research-based article, Dr. Farrell cuts through the noise with the kind of clear, no-nonsense insight she's known for. She examines the actual evidence behind the most popular ingredients, from omega-3 fatty acids and ginkgo biloba to the trendy mushroom and amino acid blends flooding the market right now. Some of it holds up. A lot of it doesn't.
"For healthy adults chasing a mental edge, the science doesn't yet support the price tag or the risk."
-- Dr. Patricia A. Farrell
The article takes a hard look at one of the most heavily advertised products in this space, Prevagen, whose makers faced a jury finding in 2024 that many of their advertising claims were materially misleading. That verdict came years after the Federal Trade Commission charged the company with deceptive advertising. By that point, consumers had already spent more than $165 million on a product whose own clinical trial data had failed to show meaningful benefit.
There's something even more alarming than weak evidence. In May 2025, the FDA issued a serious warning about tianeptine, a compound being sold at convenience stores and gas stations under names like Neptune's Fix. It's turned up in products marketed as cognitive enhancers, and health authorities have bluntly called it 'gas station heroin.' The FDA had already received reports of seizures, loss of consciousness, and death.
Dr. Farrell also addresses the drug interaction danger that doesn't get nearly enough attention. Studies show that between 23% and 82.5% of older adults who take supplements are also on prescription medications, creating a significant and underreported risk. Most people never tell their physicians what they're taking, assuming that 'natural' means safe. It doesn't. Liver damage linked to supplements accounts for an estimated 2,700 deaths in the United States every year.
The article doesn't leave readers without guidance. Dr. Farrell offers concrete steps: look for third-party testing seals from groups like USP or NSF, tell your pharmacist everything you're taking, and be skeptical of any product that promises to reverse years of cognitive aging. She also reminds readers that regular exercise, quality sleep, a diet rich in fish and vegetables, and staying socially connected have more solid science behind them than anything currently sold in a bottle.
