Hiyo is a non-alcoholic social tonic designed to produce a calm, loosened-up feeling without alcohol. The brand calls this sensation “the float,” described as lower stress levels and feeling more present in the moment. Most people notice the effects within 20 to 30 minutes, and the experience lasts roughly 2 to 3 hours.
What “The Float” Actually Feels Like
The sensation Hiyo produces is subtle compared to alcohol. You’re not going to feel intoxicated or impaired. What most people describe is a noticeable wave of relaxation, sometimes paired with a mild lift in mood and energy. One Forbes reviewer described sinking into the couch with “a noticeably relaxed sensation” after a single can. Some people also report feeling more socially at ease or mentally clear, without the foggy crash that comes with a drink or two of alcohol.
The experience varies from person to person. If you’re already relaxed and in a calm environment, you may barely register the effects. If you’re wound up after a stressful day, the shift in how you feel tends to be more obvious. It’s closer to the feeling of taking a few deep breaths and having your shoulders drop than it is to any kind of buzz.
What’s in It and How It Works
Each 12-ounce can contains 1.7 grams of a blend of adaptogens, nootropics, and botanicals. Three ingredients do most of the heavy lifting: ashwagandha, L-theanine, and lion’s mane mushroom. They each target a different part of the relaxation equation.
Ashwagandha is the stress-reduction workhorse. It works by lowering cortisol, your body’s primary stress hormone. In a 60-day clinical trial, people taking a full-spectrum ashwagandha extract saw their cortisol levels drop by about 28%, compared to roughly 8% in the placebo group. That’s the ingredient most responsible for the “tension melting away” part of the experience. You won’t get the full benefit of a daily supplement from a single can, but it contributes to the immediate calming effect.
L-theanine is an amino acid found naturally in green tea. It shifts your brain’s electrical activity in ways associated with relaxed, sustained attention. Think of it as the ingredient that keeps you alert and present rather than drowsy. Research shows it helps with focus during mentally demanding tasks, which is why Hiyo feels more like “calm and sharp” than “calm and sleepy.”
Lion’s mane mushroom is the mood component. Its active compounds cross into the brain and stimulate the production of nerve growth factor, a protein involved in brain cell health. People with depression tend to have significantly lower levels of this protein, which is why lion’s mane has drawn interest for its mood-supporting effects. In a pilot study with young adults, those taking lion’s mane for 28 days reported meaningfully lower subjective stress than those on a placebo.
Timing and Duration
The adaptogens and amino acids in Hiyo absorb within 20 to 30 minutes for most people. That’s noticeably slower than alcohol, which hits your bloodstream within minutes. If you’re drinking Hiyo at a social event, crack it open early rather than waiting until you want to feel the effects. The relaxation and mood lift typically last 2 to 3 hours, then taper off gradually. There’s no hangover, no energy crash, and no disrupted sleep afterward.
Calories and Sugar
A can of Hiyo runs about 30 calories with 5 grams of total sugar (3 grams of that added). For comparison, a glass of wine is around 120 to 150 calories, and a standard cocktail can easily hit 200 or more. If you’re switching from alcohol partly for health or weight reasons, that’s a significant difference over the course of a weekend.
Who Might Not Feel Much
Not everyone experiences a noticeable effect. People who regularly take adaptogen supplements may already have elevated baseline levels of these compounds, making a single can’s dose less perceptible. Your body weight, what you’ve eaten recently, and your current stress level all influence how strongly you respond. First-time users sometimes report that the effects become more noticeable after their second or third time trying it, as they learn to recognize the subtler shift in how they feel.
It’s also worth setting expectations correctly. If you’re looking for something that mimics the disinhibition of alcohol, Hiyo won’t deliver that. It’s designed to take the edge off and make you feel more at ease, not to replicate being tipsy. People who enjoy it most tend to be those looking for a ritual replacement for an evening drink rather than a one-to-one substitute for the feeling alcohol provides.
