L-theanine is in your tea, your feed and now your cooler. The appeal of an L-theanine drink is refreshingly simple: gentle clarity that helps you feel present, whether you mix an Outty stick or crack a Cherry Lime Yapper.
Calm focus, your way
Outty makes L-theanine easy to take into the real world. GABA and Rhodiola Rosea round out each caffeine-free stick for a smooth ritual before dinner, dates or wherever the night goes.
The smooth pairing, canned
Yapper pairs L-theanine with 100mg of natural caffeine, then adds Lion’s Mane and Panax ginseng to a bright, carbonated Cherry Lime can. Lively energy, with the edges rounded.
If you already appreciate the steady feel of tea, Outty turns that familiar amino acid into a portable, measured ritual.

L-theanine is an amino acid found naturally in tea leaves. People often describe the experience around it as calm focus or gentle clarity, which explains why it appears in both wind-down formulas and energy drinks. Its familiarity, tea origin and ability to pair naturally with caffeine have made it a favorite in modern functional beverages.
B4 states 600 mg L-theanine per packet on its label. Outty and Yapper both list L-theanine without a printed amount, so use their ingredient lists and serving directions rather than assuming a dose. Yapper contains natural caffeine, while Outty and B4 are caffeine-free.
Tea naturally contains both, so the partnership has a familiar origin. L-theanine is studied for its role in calm attention, and many people describe the combination as smoother than caffeine by itself. Yapper builds on that pairing with natural caffeine, Lion’s Mane and Panax ginseng in a bright Cherry Lime can.
Many people already consume L-theanine regularly through tea, and functional drinks offer another convenient format. Follow the serving directions and count caffeine from every source in your day. If you are pregnant, nursing, using medication or managing a health concern, ask a qualified healthcare professional what fits your situation.
Not necessarily. L-theanine is often associated with alert relaxation, a grounded feeling that does not require switching off. That is why it fits both caffeine-free Outty and naturally caffeinated Yapper, even though the two products occupy very different lanes. Experiences differ, so start with the label guidance and notice what suits you.
Tea is a beautiful ritual, but its L-theanine level can vary with the leaf, water and brew time. Outty and Yapper offer a clearly labeled serving in formats built for modern plans. You also get complementary ingredients such as adaptogens, Lion’s Mane or Panax ginseng, plus flavor without waiting for a kettle.
