Strawberry Guava Social Tonic 4ct - 48 fl oz

Hiyo was built on a single premise: the social ritual of drinking shouldn't require alcohol. The Strawberry Guava Social Tonic is their answer — a sparkling, lightly sweetened functional beverage that earns its place in your hand with a thoughtfully stacked blend of certified organic adaptogens and nootropics, not just bubbles and fruit flavoring.

Each 12 fl oz can contains 30 calories and is lightly sweetened with a combination of organic erythritol and organic cane sugar, anchored by real organic strawberry juice concentrate, organic guava purée, and organic lemon juice concentrate for brightness. The functional core — KSM-66 ashwagandha extract (the most clinically researched ashwagandha root extract on the market), organic lion's mane mushroom extract, organic passionflower extract, organic lemon balm extract, and non-caffeinated L-theanine from green tea — is designed to deliver what Hiyo calls "the float": a calm, clear-headed lift without stimulants or alcohol. This 4-pack provides four 12 fl oz cans, each a single serving.

What separates Hiyo from the growing field of functional sparkling drinks is the organic certification applied not just to the fruit ingredients but to the active botanicals themselves. Most adaptogen beverages source conventional extracts; Hiyo certifies the entire formulation USDA Organic, including the KSM-66 ashwagandha and lion's mane — a meaningful bar that very few competitors in this category clear.

Serve straight from the can, over ice, or as the base of a zero-proof cocktail — it works well with fresh lime, mint, or a splash of coconut water. The tangy strawberry-guava profile is assertive enough to hold its own in a glass without being masked by mixers.

Certified USDA Organic, Gluten-Free, Dairy-Free, and Vegan. Shelf-stable; store at room temperature and refrigerate before serving. Non-caffeinated.

Common Questions

What exactly is KSM-66 ashwagandha and how is it different from generic ashwagandha extract?
KSM-66 is a patented, full-spectrum ashwagandha root extract standardized to a minimum of 5% withanolides, the active compounds responsible for ashwagandha's adaptogenic effects. It is produced by Ixoreal Biomed using a proprietary extraction process that preserves the natural ratio of the root's constituents without using alcohol solvents. KSM-66 has been the subject of over 24 clinical trials studying outcomes including cortisol reduction, stress and anxiety scores, cognitive function, and physical endurance — a research depth that generic ashwagandha powders or undisclosed extracts cannot match. Most functional beverages that list ashwagandha on the label use commodity root powder or unnamed extracts with no standardized withanolide percentage and no clinical backing at the dose delivered. The fact that Hiyo uses KSM-66 specifically, and certifies it organic, places it in a small category of products where the adaptogen source can actually be looked up and evaluated.

How does lion's mane mushroom work as a nootropic and is there a meaningful amount of it in a beverage format?
Lion's mane (Hericium erinaceus) contains two families of compounds — hericenones and erinacines — that have been shown in laboratory and human studies to stimulate the synthesis of Nerve Growth Factor (NGF), a protein involved in the maintenance and growth of neurons. Human trials have used doses ranging from 250 mg to 3,000 mg per day, with a commonly cited double-blind study from Phytotherapy Research (2009) using 1,000 mg three times daily showing significant cognitive improvement in adults with mild cognitive impairment over 16 weeks. Beverage formats typically deliver lower doses than capsule studies, so the effect in a single can is likely subtle rather than acute. What Hiyo's formulation does by combining lion's mane with L-theanine and lemon balm is stack multiple calming and focus-supporting mechanisms, which may produce a more noticeable composite effect than any single ingredient at low dose could alone. The organic certification on the extract also matters because mushroom products can concentrate heavy metals and pesticides, making sourcing quality a genuine food safety consideration.

What is L-theanine and why is it listed as non-caffeinated if it comes from green tea?
L-theanine is an amino acid found almost exclusively in the Camellia sinensis tea plant, and it is responsible for the calm, focused mental state many people associate with tea drinking — distinct from the alertness produced by caffeine. It works by increasing alpha brain wave activity and modulating GABA, dopamine, and serotonin receptors, effects that have been documented in EEG studies at doses as low as 50 mg. The non-caffeinated designation on Hiyo's label refers to the extraction method: the L-theanine is isolated from green tea leaves through a process that removes caffeine, so you receive the amino acid without the stimulant that naturally accompanies it in brewed tea. This is meaningful for people who are caffeine-sensitive, drinking in the evening, or deliberately avoiding stimulants. Hiyo's entire formulation is non-caffeinated, which distinguishes it from the majority of functional energy drinks that rely on caffeine as the primary active ingredient.

How does lemon balm extract contribute to the calming effect and what does the research say?
Lemon balm (Melissa officinalis) is an herb in the mint family whose primary active compounds — rosmarinic acid and flavonoids — inhibit the enzyme GABA transaminase, which normally breaks down GABA in the brain. By slowing GABA breakdown, lemon balm effectively raises available GABA levels, producing mild anxiolytic and sedative effects without the drowsiness associated with pharmaceutical GABA modulators. A 2014 study published in Nutrients found that a single dose of 300 mg lemon balm extract significantly reduced self-reported anxiety and improved mood in healthy volunteers. Combined with passionflower extract — which works through a similar GABA-modulating pathway — and L-theanine, Hiyo stacks three distinct but complementary mechanisms for reducing stress signaling, rather than relying on a single compound. This multi-pathway approach is one reason the brand describes the effect as a "float" rather than sedation or stimulation.

Is this drink appropriate for people avoiding sugar, and how does the erythritol-cane sugar combination affect blood glucose?
Each can contains 30 calories and uses a combination of organic erythritol and organic cane sugar as sweeteners. Erythritol is a sugar alcohol that is absorbed in the small intestine and excreted unchanged in urine; it has a glycemic index of essentially zero and does not raise blood glucose or insulin in clinical studies. The small amount of organic cane sugar provides the trace calorie count and likely contributes to mouthfeel and flavor balance, but the total carbohydrate load per can is low enough that the product is generally considered compatible with low-sugar dietary patterns. People following strict ketogenic protocols should check the nutrition label for net carb count, as individual tolerance to small amounts of cane sugar varies. Erythritol is also one of the better-tolerated sugar alcohols — unlike maltitol or sorbitol, it rarely causes the digestive upset that some people experience with other polyols at typical serving sizes.

What does the USDA Organic certification actually guarantee for a functional beverage like this, and why does it matter for adaptogens specifically?
USDA Organic certification requires that all certified ingredients are grown without synthetic pesticides, synthetic fertilizers, or genetic modification, and that the operation passes a third-party audit at least annually. For a sparkling water or juice-based drink, this mostly affects fruit and flavoring quality. For adaptogens and mushroom extracts, however, the standard matters considerably more: plants like ashwagandha and mushrooms like lion's mane are bioaccumulators, meaning they tend to concentrate whatever is in their growing medium — including heavy metals, pesticides, and mold mycotoxins — at higher levels than most crops. Requiring organic certification for the active botanical ingredients, not just the fruit base, is a meaningful quality threshold that most competitors in this category do not meet. Most adaptogen beverage labels source conventional extracts where the agricultural and extraction standards are opaque. Hiyo's approach of certifying the full formulation, including KSM-66 ashwagandha and lion's mane, provides a documented chain of custody that a consumer can verify through the USDA's organic integrity database.

How does Hiyo compare to other non-alcoholic social drinks like Athletic Brewing, Kin Euphorics, or kombucha in terms of what it actually delivers?
Athletic Brewing and similar non-alcoholic beers are primarily about mimicking the sensory experience of beer — carbonation, malt flavor, social signaling — without any functional botanical stack; they contain no adaptogens, nootropics, or stress-modulating compounds. Kin Euphorics is the closest direct comparison: it also uses a nootropic and adaptogen stack with GABA precursors, but Kin's formulations include caffeine from rhodiola and GABA directly (which crosses the blood-brain barrier poorly in supplemental form), and Kin products are generally not USDA Organic certified across their full ingredient deck. Kombucha delivers live probiotic cultures and organic acids from fermentation, which supports gut health through a completely different mechanism — it provides no adaptogenic or nootropic compounds unless explicitly added. Hiyo is specifically built around non-caffeinated calm and clarity rather than energy, which narrows its target use case to winding down, social settings where alcohol would otherwise appear, or afternoons when focus without stimulation is the goal.
