What's Actually in Here and Why It Matters.
L-Theanine + Caffeine: Same Coffee, Different Feeling
L-theanine supports calm, alert focus. When it's already in your creamer, it reaches your system at the same time as your caffeine, which is exactly how it's formulated to work. You get the mental sharpness from coffee without the edge that makes it hard to sit still.
MCT (C8 + C10): Clean Fuel That Doesn't Spike
Organic Coconut MCT, specifically the C8 and C10 chains, gives your brain a clean, fast-burning fuel source. Unlike sugar-based creamers that spike and crash, MCTs deliver a steadier kind of energy.
Turkey Tail: Working Quietly in the Background
Turkey Tail has been used for centuries and is one of the most studied functional mushrooms for immune resilience. It's in every serving of Brain Boost — quietly supporting your immune system while you go about your morning.*
Reishi: The Adaptogen in Your Coffee Cup
Reishi has a long history of use as an adaptogen — an ingredient that helps the body manage demanding days more gracefully. It's not a stimulant. It's the opposite: a quieting influence that supports your body's own balance while the caffeine does its thing.*
No Sugar. No Dairy. No Artificial Anything.
Brain Boost is sugar-free, dairy-free, vegan, non-GMO, and keto-friendly. It's sweetened with organic glycerin — no artificial sweeteners. Sunflower lecithin is included for bioavailability, so the ingredients actually get where they need to go. Made in the USA in a cGMP-certified facility.*
Three Systems. One Squeeze. Already in Your Coffee.
L-theanine for calm focus. MCT for steady fuel. Five functional mushrooms for immune support and adaptogenic balance. No capsules to time separately. No powder to measure. No earthy taste to gag through. Just a squeeze of hazelnut chocolate creamer into the coffee you were already going to make.

What Coffee Drinkers Are Saying
All Around Game Changer
"I've been super intrigued by the benefits of functional mushrooms, specifically the coffee blends. But I LOVE real coffee, and I don't really have any desire to give that up. This is the perfect middle ground."
"Since I'm lactose intolerant, I love that it's vegan and dairy-free. It has a nice syrupy texture that mixes really well with my coffee. It's not too sweet, and the hazelnut flavor goes great with the coffee taste."
Formulated With Purpose
Made in the USA. cGMP-certified facility. 30-day guarantee.
Built for Your Coffee. Not Just Added to It.
The pairing of L-theanine with caffeine has a long track record in the functional ingredient space. MCTs, specifically the C8 and C10 chains, are a recognized source of fast-available fuel for the brain and body. And the five mushrooms (King Trumpet, Turkey Tail, Antrodia, Maitake, Reishi) each have distinct histories of use in traditional and functional wellness.
Love It or Your Money Back. 30 Days. No Hoops.
Brain Boost should earn its place in your morning. Try it for 30 days. If the jitters don't ease up, if the focus doesn't feel different, or if you just don't love it — contact us and we'll refund you. No form to fill out. No empty bottle to mail back. You tried it and that's enough.
Your Coffee Ritual. Finally Working With You.
You already drink coffee every morning and we're not asking you to change that. All you need to do is squeeze something into it. The L-theanine, MCT, and five functional mushrooms are already measured, already flavored, and already in the bottle. It's the same ritual, upgraded.
