The Psychoactive Solution To Alcohol?
Sentia is the brainchild of Professor David Nutt, former UK drug czar turned neuro-alchemist, who promises that replacing booze with botanicals can still leave you feeling relaxed and social – without the mental and physical hangups and hangovers. His introductory, fresh faced Trio comes in GABA Gold (for calm lifted moods and mental balance), GABA Red (relaxation and social connection) and GABA Black (energy and focus without the caffeine crash).
As a British neuropsychopharmacologist with a storied (and occasionally controversial) career, Nutt is best known for his work on how drugs affect the brain, particularly alcohol and psychoactive substances. Formerly the UK government’s chief drug advisor, he was famously dismissed in 2009 after publicly stating that alcohol was more harmful than many illegal drugs – a statement backed by bio-psycho-social research, but which ruffled political feathers.
Since then, Nutt has doubled down on science-driven policy and innovation. He co-founded GABA Labs, where he leads research into safer alternatives to alcohol. Sentia is GABA Labs’ flagship product – a “botanical spirit” designed to deliver a mellow, alcohol-like buzz by activating GABA receptors using natural plant-based compounds. The brain’s GABA (gamma-aminobutyric acid) system plays a central role in relaxation and mood regulation.
Going For GABA Gold
There’s no shortage of non-alcoholic drinks on the market including kombuchas, adaptogenic tonics, and zero-proof aperitifs. Most of them focus on taste, aesthetics, and the social ritual of drinking, so while they succeed at helping people feel part of the party, they often fall short in how they actually make you feel from within.
GABA Spirits believe that they are different. Although other botanical products can and do activate GABA receptors, they aren’t intentionally formulated with this in mind – signifying a lack of potency; “Many Alcohol-Free options mimic flavours well but often fall short on function.” Sentia Spirits have honed in on this sensational gap, with botanical blends that seek to establish their own sensory highs and “mouthfeels.”
In terms of effectiveness, Sentia admit that: “We’re all unique and individuals report experiencing the flavour and sensation of Sentia in different ways.” With on-going feedback and iterations expected to play a vital role in the evolution of the brand. What sets GABA apart is their scientific approach to synthesising and concentrating herbal ingredients, alongside gathering a stronger evidence base of the holistic effects.
While they take inspiration from nature, their “botanical” spirits won’t always be au naturel either – “GABA Labs will bring the Alcarelle series of synthetic ingredients (including “Alcosynth”) and its active botanical ingredient, known as “ABI”, to market and license this technology to the Drinks Industry. They will create new ranges of drinks that give some of the social and conviviality benefits of alcohol whilst reducing the risks of harm… In order for this to [happen], Alcarelle will have to go through a rigorous regulatory process. This is likely to take between three and five years.”
Relaxing Red Flags
GABA is a natural substance that is widely distributed in nature among microorganisms, plants and animals. It is most prevalent and developed in mammals, and particularly in those that rear and take care of their young; It is also believed to have been a key factor in human’s evolution as social beings. Both humans and our pre-human ancestors are believed to have consumed alcohol for over a million years, making it one of the most widely used psychoactive substances on the planet.
As a result, GABA Labs’ research into GABAergic often uses extracts from approved food-plants that are already well-established in the food and drinks market. This is much more easily scalable and marketable from a legal stance, given that these are not novel foods. So is GABA like Ethanol? Looks fancy – tastes complicated.
At low doses, 1-2 units or 15-10gms of ethanol (one to two drinks) a blood ethanol level of 40-100mg% is produced. At this blood concentration, ethanol helps reduce anxiety primarily by activating GABA to reduce brain excitability. This explains why ethanol is so popular at parties where many of us use it to overcome the natural social anxiety about talking to strangers. It has been long understood by airlines, who quickly offer ethanol on a flight to calm the anxiety of air-passengers who dislike flying.
But at higher concentrations (blood ethanol >150 mg%) ethanol begins to act as an antagonist at the NMDA receptor leading to impaired judgement and the memory block we’ve come to expect as “blackouts”. At higher levels (blood ethanol >400mg%, as would occur after drinking a litre of vodka) these two effects of ethanol – the increase in GABA inhibition and the blockade of glutamate excitation – can combine to produce a lethal level of sedation and respiratory depression.
At these doses, ethanol causes significant damage to human tissue, particularly the brain and nervous system, heart, liver and pancreas. As it is so widely accessible, industrially processed, and culturally integrated – in terms of health impacts, alcohol (strictly speaking, ethanol) is currently in a class of its own. However this highlights that while the properties of substances can be attenuated to limit negative effects, a holistic approach to holistic materials also needs to consider the wider aspects of the system in which they are embedded.
Back To Black
Connection is at the heart of what it means to be human and drinking often defines these moments; At its core, drinking isn’t just about the liquid in the specially designed glass – it’s a ritual, signal, and a social anchor. Whether it’s the wine at the end of the day or a round of shots on someone’s birthday, alcohol is woven into how we celebrate, unwind, communicate, and cope. Sentia’s over-arching goal is to focus on the “Natural sweet spot… You know that sensation when your first drink hits – conversations broaden, connections deepen and the noise in the room rises?”
There’s a fine line between chemical calm and creative chaos, and while Sentia isn’t a magic bullet for the range of factors at play in dependency and addiction, it can be a harm-reduction tool and offer transitional support for those rethinking their relationship with alcohol. Whether you’re in recovery or just re-evaluating a lifestyle choice, products like Sentia offer a middle path that supports your goals without feeling like a punishment.
Sentia’s rise taps directly into the growing popularity of biohacking – the movement obsessed with optimising the body and brain through science, supplements, and self-experimentation. Where biohackers once chased ketones and blue light blockers, many are now turning their attention to alcohol alternatives that promise the feel-good effects without the metabolic or cognitive toll. Sentia fits perfectly into this niche: as a targeted intervention (a neurochemically-informed hack) for social connection and stress relief that speaks to the biohacker’s desire for pleasure with precision.
In theory, unlike most mocktails, herbal tonics, and CBD-infused beverages, Sentia is designed with a mechanism of action in mind, appealing to those who track their macros, monitor their sleep cycles, and optimise their neurotransmitters in pursuit of better living. And attitudes with greater evidence-base behind them are a welcome intervention. However in practice, it may not yet be quite potent enough to live up to its claims, or to justify and incentivise repeat purchase.
At £30+ a bottle Sentia isn’t cheap, and while advocates may argue that it still costs less than the price of your liver, there are popular and established herbal brands that feel similar in affect – despite the lack of literature. It’s not snake oil. It’s just… not your usual snake? While Sentia’s admirable USP is their mission to suss out psychoactivity in a way that’s both heartily and healthily hedonistic, we have barely scratched the surface of these complex fields. Their blends don’t quite feel distinctive enough, and can still leave you prone to headaches and the side-effects of other zeitgebers.
What’s interesting is the zone-in on GABA. Especially since many of us have already heard of other neurotransmitters like serotonin, endorphins and dopamine. Like other lesser-known neurotransmitters, GABA also plays a crucial role in fully-functioning / health and wellbeing. GABA Labs explain that the date of GABA’s scientific confirmation as a neurotransmitter in the central nervous system was relatively recent (1971), especially compared to these: noradrenaline (1945); serotonin (1953); dopamine (1958). Scientific breakthroughs can sometimes accelerate awareness, but often it’s changes to public policy that create the biggest impact.
GABA Labs have modelled Japan as a regulatory examplar: in 2015 the Japanese government introduced a new food classification, “Food with Functional Claims”. This scheme involved reduced (though still stringent) certification requirements. This unleashed a food innovation revolution in Japan, and GABA featured heavily in it. In fewer than 4 years, GABA became a well-established food additive in Japan, and now almost everyone there has heard of it. You can find GABA chocolate, GABA drinks, and GABA cakes, with their functional claims centring around relaxation, dealing with stress and improving sleep.
The equivalent in the UK has been the mainstreaming of “non-psychoactive” molecules like CBD (cannabidiol) as a wellness trend. Marketed as a natural remedy for anxiety, inflammation, and sleep issues, CBD has been embraced by curious consumers looking for plant-based ways to manage stress. However, while it’s widely available and legal (under certain terms and conditions), the scientific evidence supporting its effectiveness in food-grade doses remains limited. Most products use CBD in relatively low concentrations, meaning the effects are often subtle or more placebo than powerful – but that hasn’t stopped its rise as a fashionable, feel-good ingredient in the UK’s evolving landscape.
While Sentia as a commercial arm may have some way to go, the research output from GABA Labs holds significant value not only for the wellness and beverage industries but also for the broader fields of neuroscience, mental health, and public health policy. Their work bridges the gap between cutting-edge pharmacology and real-world application, offering alternatives that are both evidence-based and ethically-motivated. In a world grappling with the societal and health costs of alcohol, GABA Labs’ output represents a rare combination of rigorous science, harm reduction, and consumer innovation, setting a new standard for what functional beverages might become.
