Quick intro (and a tiny confession)
I love coffee. Like, love-love. Earlier this year, I even spent a month testing a dedicated nootropic coffee on its own—here’s what actually happened. But my brain? It can get jumpy. Busy mornings, drop-off line, Slack pings, a full inbox—my head spins. So I tried nootropic creamer to see if it could help me feel calm and focused without that wired crash. I used two: Keto Brainz Nootropic Creamer and Four Sigmatic Think Creamer. I used them almost every day for a month. Different ways. Different tasks. Some wins. Some fails. If you’re curious about my day-by-day notes, you can skim the full rundown here.
Let me explain what happened.
What I used, in plain words
- Keto Brainz Nootropic Creamer: It’s powder. It has MCT oil, lion’s mane, and L-theanine. The jar has a tiny scoop. No sweetener.
- Four Sigmatic Think Organic Creamer: Also powder. Coconut base, MCT, lion’s mane. Lightly sweet, but still pretty mild.
Both are made for coffee or tea. I put them in hot coffee, cold brew, and even cocoa once when I ran out of milk. That last one? Weird, but cozy.
Taste and texture: the small stuff matters
- Keto Brainz: Not sweet. Mild coconut and nutty notes. In hot coffee, it blends smooth with a cheap handheld frother. In cold brew, it clumps if I just stir. I had to shake it in a jar, like a tiny cocktail. No foam cap, which I missed.
- Four Sigmatic: A bit sweeter and creamier. Easier in cold brew. Still better with a frother. Tastes like a light coconut latte, which sounds fancy, but it’s chill.
Both can leave a little oil ring if you don’t mix well. It looks odd—but it didn’t bother me after day three. My mug, my rules.
Real days, real tests
-
Monday, school drop-off + email triage:
I did one scoop of Keto Brainz in a small Americano. I set a 25-minute timer and worked in a sprint. My brain felt steady. Not buzzy. I wrote a clean status update with no weird rambling. That’s rare for me before 9 a.m. -
Wednesday, Zoom stack:
I tried Four Sigmatic during three back-to-back calls. I didn’t hit that 10 a.m. slump. I took good notes. I even kept my camera on the whole time. Win. -
Friday, writing deadline:
Two half-scoops of Keto Brainz across two cups. I felt locked in for about two hours. I had this tunnel vibe, but not tight in the chest. I took a 5-minute walk, came back, and finished edits fast. I didn’t forget to eat, which is big for me. -
Long drive to my mom’s:
Four Sigmatic in a travel mug. No crash on the highway. I still stopped for gas snacks, but I didn’t grab a sugar bomb. That told me a lot. -
Saturday, gym day:
I tested it with matcha before a light lift. Calm focus, but I wouldn’t pick this for a heavy squat day. Coffee plus creamers and deep core work? Not my favorite combo. -
Late-night reading:
I tried a half scoop with decaf. It made my brain feel too awake for bed. That part backfired. I just kept turning pages.
Did it help my focus?
Short answer: Yes—most days. It felt like a soft filter on noise. I could hold a thought and finish a task without doom-scrolling between steps. The L-theanine (that’s the “calm” amino) took the edge off caffeine. Lion’s mane is the mushroom piece; I can’t prove anything big there, but I felt more on-task. If mushrooms perk your interest, I also tried a proprietary mushroom blend and shared my real take.
I did have one weird day when I drank a strong cold brew with a full scoop of Keto Brainz. My stomach said no thanks. The MCT oil can do that if you go hard. Go slow first.

What I didn’t love
- Price per serving: Both are not cheap. My math landed around $1 to $1.50 a cup, depending on scoop size and sales.
- Mix-in drama: In cold drinks, it clumps if you just stir. Frother or blender is your friend.
- Flavor: If you want a sweet, cafe-style latte, you’ll need to add your own sweetener or cinnamon. These are “grown-up” flavors. Kind of plain.
- Stomach notes: Fasted mornings with a big scoop gave me light tummy rumbles. Half scoop fixed it.
- Packaging: Keto Brainz jar is cute, but the scoop hides. I had to dig with a spoon like a raccoon.
Little tips that made it better
- Start with a half scoop. Let your gut adjust.
- Use a frother. Even a cheap $10 one. It’s worth it.
- Hot coffee mixes best. For iced, shake it in a jar first.
- Add cinnamon or a pinch of cocoa. Makes it feel fancy.
- If you’re new to MCT oil, eat a small snack first. Like a banana or toast.
Who it’s for (and who might skip)
- Good for: Folks who want steady focus, keto fans, remote workers, students, and anyone who gets jittery from coffee alone.
- Maybe skip or ask your doc: If you’re pregnant, very caffeine-sensitive, or you have tummy issues with oils. I’m not a doctor. Just a lady with a mug.

Tiny seasonal note
I tried a pumpkin spice riff at home—coffee, Keto Brainz, a shake of pumpkin spice, a splash of oat milk. It tasted like a candle, but in a good way. Cozy, not sweet.
Final verdict
- Focus: 8/10
- Taste: 7/10 (Four Sigmatic edges out here)
- Mixability: 6/10 without a frother, 9/10 with one
- Value: 7/10
Would I keep using nootropic creamer? Yes, but not every single day. On heavy work days, I reach for Keto Brainz for that clean, calm feel. On lighter days, I use Four Sigmatic for the smoother taste. When I want a treat, I add cinnamon and sip slow.
You know what? Coffee still brings the spark. The creamer just makes it quieter, kinder, and a bit more focused. That was the surprise.
If you try it, start small, mix well, and listen to your gut—literally.
