What's inside / what it does
Bubbles that actually earn their keep.
We start with real pressed fruit, add a measured dose of functional botanicals, and stop there. No 40 grams of sugar, no jittery caffeine bomb — just a crisp, grown-up soda that leaves you better than it found you.
- Steady, not sleepy
Ashwagandha & L-theanine take the edge off without dimming the lights. - Focus you can feel
Lion's mane & rhodiola for the kind of clear head a coffee can't fake. - Kind to your gut
6g of prebiotic fiber per can — your microbiome says thanks. - No 4pm cliff
5g of sugar means no spike, no slump, no regret.

Loved out loud
People are weirdly obsessed.
"I quit my afternoon energy drink cold turkey. Sunburst Grapefruit tastes like a treat and I'm somehow calmer by 4pm. Witchcraft."
"Deep Dive replaced my nightly glass of wine. Zero regret in the morning and my fridge finally looks cool. Ten out of ten."
"Cosmic Cola is the first 'healthy' soda that doesn't taste like a compromise. My cola-obsessed teenager stole the whole pack."

Good questions
Before you stock up.
Are adaptogens actually doing anything?
Each can carries a real, measured dose — 150mg ashwagandha, 200mg L-theanine, and so on — not a sprinkle for the label. They won't rewire your life, but a lot of people notice a steadier afternoon. We keep the claims honest and the amounts printed on every can.
How much sugar is in here?
Five grams, from a touch of real cane sugar and pressed fruit — about a tenth of a regular soda. Enough to taste like a treat, not enough to send you off a cliff at 4pm.
How does shipping work?
We ship nationwide across the US, cold-packed and carbon-neutral. Orders over $35 ship free and usually land in 2–4 business days. Not in love? Our 30-day happiness guarantee has you covered.
Is checkout secure?
Completely. Payment runs through Stripe's hosted, PCI-compliant checkout — your card details go straight to Stripe and never touch Zephyr's servers. Apple Pay and Google Pay are one tap away.
