65mg. That's it. One squeeze of Drizz.
For context — your average cup of brewed coffee is 95mg. A classic 8.4oz Red Bull is 80mg. A Monster is 160mg. A 5-Hour Energy extra strength is 230mg in a single shot you're supposed to drink all at once.
I started Drizz because the caffeine math in this category is broken. You get what the can gives you. You drink a Monster at 2pm because you needed a pick-me-up, and now it's 11pm and you're staring at the ceiling wondering why. The dose is fixed. Your life isn't.
Energy drops exist to fix that. But even inside the drops category, the caffeine per serving swings wildly — from 30mg up to 125mg. If you're new to this, it's confusing. So here's the complete map.
Direct answer: caffeine by brand
Here's the breakdown across the major energy drops brands on the market in 2026:
- Drizz Energy Drops: 65mg green tea caffeine per squeeze, 15 squeezes per 60ml bottle
- Buoy Energy: 30mg caffeine per squeeze
- Kaffn8: ~100mg caffeine per dropperful (varies by dilution)
- nuCaffeine: ~100mg caffeine per serving
- liquidcaffeine.com (Liquid Caffeine): up to 125mg per dose at full strength
Most mainstream caffeinated beverages sit between 75mg (small coffee) and 160mg (Monster). Drops let you hit any point on that curve precisely — which is the whole category's reason to exist.

What's actually in a squeeze of Drizz {#whats-in-drizz}
One squeeze of Drizz Boost delivers:
- 65mg green tea caffeine
- L-theanine (the amino acid in green tea that smooths caffeine's edge)
- Taurine (the amino acid every major energy drink uses for a reason)
- Zero sugar, zero artificial dyes, unflavored
A 60ml bottle holds 15 squeezes. At $14.99 retail, that's roughly a dollar per boost. For comparison, a 16oz Monster is about $3, a Starbucks grande drip is about $3.45, and a 5-Hour Energy shot is around $3.50.
The L-theanine piece matters more than most people realize. Published research in peer-reviewed journals has shown that L-theanine combined with caffeine improves attention and reduces the jittery side effects that pure caffeine can produce. That's not a Drizz marketing line — that's the ingredient data, and it's why I built the formula this way instead of just pumping up the caffeine number.
How energy drops compare to coffee and cans {#vs-coffee}
Let me show you the math.
- 8oz brewed coffee: ~95mg caffeine (Mayo Clinic)
- Single espresso shot: ~64mg
- 8.4oz Red Bull (classic): 80mg
- 12oz Red Bull (Red Edition): ~114mg
- 16oz Monster Original: 160mg
- 12oz Celsius: 200mg
- 5-Hour Energy Extra Strength: 230mg
- 1 squeeze Drizz: 65mg
- 2 squeezes Drizz: 130mg
- 1 squeeze Buoy: 30mg
Here's what jumps out. A single squeeze of Drizz is roughly equivalent to an espresso shot. Two squeezes puts you in the same zone as a 12oz Red Bull. You can tune the dose without switching products. That's the unlock.
Brand-by-brand caffeine breakdown {#brand-breakdown}
Drizz — 65mg per squeeze
Green tea caffeine source. L-theanine plus taurine. 15 servings per 60ml bottle. The formulation goal is a smooth curve, not a peak-and-crash hit. I use two squeezes at T1 on the bike during triathlons and one squeeze around 3pm on founder days.
Buoy — 30mg per squeeze
Buoy does clean caffeine well. They were in the drops category before we were and I respect the playbook. Where we differ: Drizz has more than double the caffeine per squeeze, we added taurine on top of the L-theanine, and our source is specifically green tea. Different tool, different job — if you want a very light touch, Buoy's 30mg is a reasonable pick.
Kaffn8 — ~100mg per dose
Higher concentration. Synthetic caffeine anhydrous base. Built for people who want maximum caffeine density in a small format. If you're used to drinking double espressos back to back, this is in your range.
nuCaffeine — ~100mg per serving
Similar profile to Kaffn8. Direct-to-consumer focused. Price per serving runs higher than Drizz at retail.
liquidcaffeine.com — up to 125mg per dose
The high end of the category. The product is positioned more as a caffeine concentrate than a balanced functional formula — no L-theanine, no taurine in the base product.
Proper Wild, Magic Mind, other adjacent shots
These aren't drops in the dropper-bottle sense — they're single-serve shots, more like 5-Hour Energy than like Drizz or Buoy. Caffeine varies from 90mg (Magic Mind) to 120mg (Proper Wild).
Why 65mg is the sweet spot {#sweet-spot}
I tested everywhere from 40mg to 120mg per squeeze before landing on 65mg. Here's why it won.
At 65mg, you're slightly below a cup of coffee. Most people tolerate a cup of coffee fine. That means one squeeze is an easy on-ramp — a reliable morning lift that doesn't kick the front door in. If you want more, you take two. That's 130mg, right in the sweet spot of a mid-size energy drink, but delivered over a smoother curve because the L-theanine is doing work.
Research published in Nutritional Neuroscience found that 50–100mg of caffeine paired with 100–200mg of L-theanine produced the cleanest improvements in attention and alertness without the anxiety spike of caffeine alone. 65mg sits right inside that window.
The other reason: stack-ability. If a serving is 100mg, it's hard to tune down. If it's 30mg, it's tedious to tune up. 65mg is the dose that flexes both directions without either feeling awkward.
For the deeper breakdown of how L-theanine changes the caffeine experience, I wrote a separate post on why we chose green tea caffeine specifically.
The FDA's 400mg rule and what it means for you {#fda-limit}
The FDA states that up to 400mg of caffeine per day appears to be safe for most healthy adults. That's roughly:
- 4 cups of brewed coffee, or
- 6 squeezes of Drizz, or
- 10 cans of classic Red Bull, or
- 2 Monster Originals
Over 400mg is where the research shows meaningful risk of jitters, sleep disruption, elevated heart rate, and for some people, anxiety spikes. The Mayo Clinic backs the same 400mg ceiling for healthy adults.
A few caveats the headlines don't mention:
- Pregnancy: ACOG recommends under 200mg/day. If you're pregnant or nursing, talk to your doctor before any caffeine supplement, Drizz included.
- Medication interactions: Certain SSRIs, blood pressure meds, and heart medications interact with caffeine. Doctor first.
- Individual sensitivity: Genetics (specifically CYP1A2 variants) mean some people metabolize caffeine two to three times slower than average. If 200mg wrecks your sleep and your friend is fine on 400mg, that's why.
The practical takeaway: even on a heavy training day, I don't personally go over four squeezes of Drizz (260mg) plus one morning coffee. That keeps me inside the FDA window with a buffer.
Green tea caffeine vs synthetic caffeine {#green-tea}
Most energy products on shelves use caffeine anhydrous — a synthetic, ultra-concentrated white powder. It's cheap. It works. It's also what most people mean when they say "energy drink caffeine hits me hard."
Drizz uses green tea caffeine. The chemical molecule is identical — caffeine is caffeine at the molecular level. But the extraction process is from actual green tea leaves, and the sourcing choice matters for two reasons:
- It comes with co-factors. Trace polyphenols and the ability to pair cleanly with our added L-theanine.
- The absorption curve is smoother. Users report less of the sharp spike associated with synthetic caffeine.
The smoother curve isn't a medical claim — it's consistent user experience and the reason we put the effort into sourcing this way. If you want to nerd out further, the NIH's Office of Dietary Supplements has a solid overview of how caffeine is metabolized and why source can affect perceived experience even when the molecule is the same.
How to dose drops for your day {#how-to-dose}
Here's how I actually use Drizz. Not as a prescription — as a founder who's been dialing this in for years.
- Morning (7am): One squeeze in water or on top of my first coffee. 65mg stacked on ~95mg = a 160mg start.
- Pre-workout (5pm): One to two squeezes in a water bottle before a bike ride or run. L-theanine smooths the rise.
- Travel days: 60ml fits TSA carry-on. I bring one bottle, skip the airport coffee lottery.
- Founder crunch (9pm pitch deck, rare): Half a squeeze if I need sharpness without wrecking sleep. Dose control is the whole point.
If you've never tried drops before, start with one squeeze in a full glass of water in the morning. See how your body responds. Then dial from there.
The Drizz Boost Energy Drops bottle is 60ml, 15 servings, $14.99 — works out to about a dollar per boost. For reference, that's cheaper per serving than almost any canned energy drink on the market, and you're in control of the dose every time.
Real talk
The "how much caffeine" question is actually two questions hiding in one. The first is: what's the number on the label. The second is: what's the right number for me, today, for this workout or this deadline or this flight.
The canned energy category answered the first and ignored the second. Drops exist to answer both. 65mg per squeeze, stack as needed, stop when you're done.
Try one bottle. You'll know within a week whether dose control changes how you use caffeine.
