Why Flowy exists

Most pre-workouts trade your evening for a spike, and your sleep for a buzz. We built the opposite.

Flowy is the pre-workout that respects your evening. Nitric-oxide-first — it widens the pipes so more oxygen gets where it needs to go — then fills you back up with what you lose in sweat. The kind of session you can repeat on a Tuesday after work, six weeks in a row.

  • 01Zero caffeine. Train at 8pm and still fall asleep at 10. The energy is in the blood flow, not the bloodstream.
  • 02A clean off-switch. No second-half-of-the-day tremor. No 2am ceiling stares.
  • 03No tingles, no itch. We left the beta-alanine out so you're not buzzing through dinner.
  • 04No proprietary blends. Every dose disclosed. 5 calories. Stevia-sweetened, real lemon lime.
How Flowy works

The pump without the espresso shot.

Caffeine isn't what makes a pre-workout work — blood flow is. Here's how Flowy delivers the same energy and pump a stim-loaded scoop does, without anything that lingers past your session.

Step 01 — Absorb

L-Citrulline converts to L-Arginine.

Your body turns it into nitric oxide, which tells your blood vessels to relax and widen — 30–60 minutes after your scoop hits water.

Step 02 — Deliver

More oxygen reaches working muscle.

Wider vessels mean more fuel and more oxygen per heartbeat. Translation: the set that used to cook you feels easier.

Step 03 — Replace

1,087mg electrolytes keep you full.

Sodium from pink Himalayan salt, potassium, magnesium malate — dosed high, in forms your body actually absorbs. You stay topped up instead of dragging through set five.

The short list

Four things you'll actually notice. After dinner.

01 · Endurance

The 7pm session that hits like a 7am one.

L-Citrulline opens vessels. Beet root keeps them open. Oxygen keeps showing up when you need it most — even at the end of a long day, when you swore you were too tired to lift.

Output curve — hour-long session
02 · Sleep

Train hard. Sleep deep.

Zero stimulants means zero half-life cooking your nervous system at midnight. Your Oura ring will notice.

03 · Focus

Sharp, without the tremor.

More oxygen to the brain without caffeine's signature spike. You stay present in the set, not jittery through the rest of your evening.

04 · Hydration

Electrolytes by the gram, not the gesture.

1,087mg per scoop replaces what you sweat out, so you're not chasing water at 11pm.

Evening ritual

Scoop at 6:30. Lift at 7. Dinner at 8:30. Asleep by 10:30.

Built for people whose only window is after work — spin class at 7, BJJ at 8, the basement gym after the kids go down. Flowy works the same way every time, and clocks out when you do.

What's in the scoop

Every gram does a job.

No proprietary blends. No filler. Here is exactly what a single 11.92g scoop delivers, and why each ingredient earned its spot.

01
L-Citrulline Malate 2:1
The nitric-oxide precursor. Converts to L-Arginine, then to NO — widening vessels 30–60 min after your scoop hits water. This is the ingredient that drives the pump.
6,000 mgclinical dose
02
Beet (Beta vulgaris) Root Extract
Natural source of dietary nitrates. Works alongside L-Citrulline to boost NO production, endurance, and oxygen efficiency. Also why the color stays honest.
1,000 mgnitrate source
03
Potassium (Citrate + Chloride)
The electrolyte most people under-dose. Keeps muscle contractions steady and lets your nervous system talk to your muscles without delay.
650 mg14% DV
04
Sodium (Pink Himalayan Salt)
The mineral you lose most in sweat — and the one plain water can't replace. Sourced from pink Himalayan salt, not anonymous bulk sodium.
407 mg18% DV
05
Magnesium (Malate)
Required for 300+ enzymatic reactions including muscle contraction and ATP production. Malate form is gentle on the stomach and bioavailable.
30 mg7% DV
06
Lemon Lime (natural)
Natural flavoring, citric acid, a trace of organic cane sugar, stevia for sweetness. No artificial flavors or colors. 5 calories, less than 1g sugar.

The honest comparison

What you give up when you switch.

The 200mg of caffeine. The 2am ceiling stares. Not much else.

★★★★★
EXCELLENT caffeine-free pre-workout.

I drink a lot of coffee in the morning and I don't need any extra caffeine from a pre-workout. This is the first one I've found that makes a perfect blend of excellent ingredients and it really helps my workouts.

★★★★★
Great for late-night climbing.

I've been using Flowy for over a month and I am impressed. Boost of energy for at least an hour while climbing and the pump goes longer as well. I take it anytime I've already had caffeine that day.

What I have been searching for.

I've been trying different 'no caffeine' pre-workout powders for years and Flowy is my favorite. It gives me that late-afternoon energy boost without interrupting my appetite for dinner or sleep.

★★★★★
Great for feeling your best.

I really like that there's no caffeine and that it helps with bloodflow. It doesn't give you jitters, it just makes you energized and you feel good. Tastes great, too.

No jitters. Just pure energy.

I usually stay away from pre-workouts because they always give me jitters. But this one was a really great experience. This is my pre-workout of choice from now on.

Evening workouts, finally.

Love this new stuff. I get a nice pump and I workout in the evenings so the no caffeine is a huge benefit. The electrolyte boost is a big plus.

Common questions

Things people ask before tub one.

Will it keep me up at night?+
No. Flowy is the evening pre-workout precisely because it has zero caffeine, zero green tea extract, and zero guarana — nothing with a half-life that lingers past your session. The "energy" comes from improved blood flow and full electrolytes, not a stimulant spike. Train at 8pm, asleep at 10.
Can I really take it after work?+
That's exactly what it's built for. Mix one scoop in 20–32 oz of cold water, 30–60 minutes before you train.
Will I feel tingles or itch?+
No. We deliberately left beta-alanine out. The tingles are a feature for some people — they're a problem when you're trying to wind down two hours later.
How is it different from plain electrolytes like LMNT?+
Electrolyte mixes solve hydration. Flowy solves hydration and performance. Same level of electrolytes, plus a clinical dose of L-Citrulline for nitric oxide.
What if I usually train in the morning?+
Works the same way. Flowy is caffeine-free not anti-caffeine — you can layer it under your morning coffee for a cleaner pump, or use it on its own.
Is it safe if I'm sensitive to stimulants?+
Flowy is a great fit for stim-sensitive folks. If you're pregnant, nursing, on medication, or managing a condition, talk to your doctor before adding any supplement — including this one.
How does it taste?+
Real lemon lime. Natural flavoring, citric acid, a trace of organic cane sugar, stevia for sweetness. No dyes. Mixes cleanly in a shaker.
What's your shipping & return policy?+
Free US shipping over $35. 60-day money-back guarantee — if you don't love it, send back what's left for a full refund. Subscriptions ship free always.
