Microdosing LSD can improve your brain function – if you’re a woman

Taking microdoses of LSD can improve cognitive performance and focus – but only if you are a woman, according to groundbreaking new research.

In a clinical study published in Nature, scientists investigating the cognitive impacts of low-dose psychedelics found that fractional doses of LSD enhanced sustained attention in female participants, while male participants showed no significant change.

The findings challenge long-held assumptions about uniform drug responses, offering one of the first controlled, scientific explanations for why microdosing has gained widespread traction among women seeking focus and cognitive enhancement.

“The key finding was that LSD improves how women can sustain attention in certain tasks,” explained lead researcher Iva Totomanova of Maastricht University.

Microdosing involves taking tiny, sub-perceptual amounts of a psychedelic substance – typically around one-tenth of a recreational dose – intended to boost productivity, creativity, and mood without causing hallucinations or altered states of consciousness.

LSD, which refers to lysergic acid diethylamide, is a particularly powerful psychedelic, which was initially explored for psychiatric use due to its structural similarity to “happy chemical,” serotonin.

Over recent years, the practice of microdosing LSD has become a popular cultural and wellness trend, first hailed by alternative wellness gurus before seeping into the mainstream, where OpenAI founder Sam Altman described a guided psychedelic experience as “life-changing.”

While millions of people have reported benefits in anecdotal accounts, testing these claims in a rigorous, double-blind placebo-controlled setting has yielded nuanced results.

During the study, female subjects demonstrated measurable improvements on standardised cognitive tests measuring prolonged focus and attentional endurance, whereas male subjects performed at levels comparable to placebo.

However, experts caution against assuming that LSD acts as an all-purpose brain booster.

Totomanova stressed this: “Instead, the results point to a more cautious message: effects may depend on the person, the cognitive task being measured, and the circumstances of use. A better question may be: who responds to microdosing, and under what circumstances?”

Outside observers agree that placing popular wellness trends under rigorous scientific scrutiny is an essential step forward for psychedelic research.

“Microdosing of psychedelics has received much attention in media, so testing this in a proper research context is important to advance our knowledge on the subject,” commented Dr Mikkel Højlund of the University of Southern Denmark, who was not involved with the study.

“Even though it is a double-blind placebo-controlled study, the researchers are cautious: as they say, this is a small study, with several variables, but it merits further work on a bigger scale.”
