Functional seltzer took the bubbles everyone already loves and gave them a job. This collection is our sparkling shelf: a lightly carbonated nootropic can that is ready when you are, and mix-in formats that upgrade whatever seltzer is already in your fridge. Carbonation is the delivery system, function is the point.
Our functional sparkling option
Full transparency: Yapper is a lightly carbonated social energy drink rather than a classic seltzer, and that is exactly why it leads this page. You get seltzer-level drinkability with Lion's Mane, L-theanine, Panax ginseng and natural caffeine doing real work underneath the bubbles.
Make any seltzer functional
The bring-your-own-bubbles option. Stir an Outty stick into any sparkling water and your plain seltzer becomes a functional one: L-theanine, adaptogens and low natural caffeine, fizz level entirely up to you.
The seltzer sidecar
Keep the seltzer you already love exactly as it is and add the function separately. A B4 packet before going out delivers six natural nootropic ingredients while your soda water stays your soda water.
Wants cold, ready and carbonated with zero assembly. A case of Yapper covers the week and every drop-in guest.

Already has a favorite sparkling water and no plans to switch. Outty upgrades it without changing the fizz.

Cans do not fly well. B4 packets bring the function through security and meet the bubbles at the destination.

Buying a functional seltzer starts with an honest look at the label, because sparkling and functional are not the same claim. Check that the actives are named and meaningful: ours run on L-theanine, Lion's Mane, Panax ginseng and adaptogens rather than a vague blend. Decide how you want your bubbles: ready-made in a lightly carbonated can like Yapper, or added to your own sparkling water with an Outty stick. Watch calories and sugar, since Yapper holds at 90 calories and mix-in formats inherit whatever your base seltzer brings, which can be zero. Note that Yapper is technically a lightly carbonated social energy drink, and we position it as our functional sparkling option because that is what it does in practice.
Sparkling water that carries active ingredients such as nootropics, adaptogens or botanicals, so the drink does something beyond refreshment. Fizz plus function is the whole formula.
Strictly speaking it is a lightly carbonated social energy drink. We put it at the top of this collection because it plays the functional sparkling role: light bubbles, big formula, zero alcohol.
Yes. Any brand, any flavor, any fizz level. Stir a stick in about 30 minutes before your plans and your everyday seltzer becomes the functional kind.
Yapper is 90 calories per can. Outty and B4 depend on what you mix them with, so a zero-calorie sparkling water keeps the whole drink lean.
Not here. Everything in this collection is zero alcohol, which is a key difference from hard seltzer.
Yapper carries moderate natural caffeine and Outty a low amount. Your base seltzer stays caffeine-free, so mix-in formats let you control the total.
