Circulation & Performance
FLOW
Better blood flow. Better performance.
Supports nitric oxide production to deliver more oxygen to working muscles — so you can push harder, recover faster, and skip the stimulants entirely.
Supports nitric oxide production for better circulation, faster recovery and steady, stimulant-free energy.
Rednite® standardized beet extract, L-Arginine, a seed-based polyphenol complex, hibiscus flower extract and a full B-vitamin complex.
Mix one packet with 8-12 oz of water and drink. Most people take it in the morning or 30-60 minutes before exercise.
Flow targets nitric oxide through two distinct pathways — the dietary nitrate pathway via Rednite® and the enzymatic eNOS pathway via L-Arginine.
The difference between a good workout and a great one is oxygen delivery.
Flow was built to close that gap.
Train Harder
More oxygen to working muscles means more output before you hit a wall.
Recover Faster
Better circulation clears waste products quicker. You feel it the next day.
Steady Energy
No spike, no crash. Just consistent energy from start to finish.
Built to Stack
Gets more effective the longer you take it. Most supplements don't do that.
The science is simple.
Nitric oxide signals blood vessels to widen — delivering more oxygen to working muscles.*
Flow fuels your body's natural Nitric Oxide (NO) production.
Nitric Oxide (NO) signals your blood vessels to widen.
More oxygen reaches your working muscles.
Expert Backed
Backed by science. Trusted by experts.
Leading researchers in sports nutrition and exercise physiology explain why Flow's dual-pathway approach works.
Most people don't realize that endurance limitations are often circulatory rather than muscular.
When blood flow is restricted, oxygen delivery drops and performance suffers — regardless of fitness level. Flow's formula addresses this directly.

What makes Flow's formulation stand out is the combination of Rednite® with L-Arginine.
Rednite® supports nitric oxide production through the dietary nitrate pathway, while L-Arginine supports it through the enzymatic pathway — two different mechanisms working toward the same outcome.

The Comparison
Not all performance supplements are equal.
Most give you a spike. Some give you beets. Flow gives you a mechanism.

Two pathways. One goal.
Your body produces nitric oxide through two different biological pathways. Flow supports both.
Nitrate Pathway
Beet Extract
Most beet supplements use generic powder with no standardization — meaning the nitrate content varies wildly batch to batch. Rednite® is different. It's the first beet extract standardized for nitrate content, so every serving delivers a consistent, meaningful dose.

eNOS Pathway
Amino Acid
L-Arginine is the direct substrate your body uses to produce nitric oxide enzymatically — independent of dietary nitrate entirely. Research shows it specifically enhances blood flow to skeletal muscle, exactly where you need it most.

"I switched to Flow because I wanted something I could take daily without stimulants. After about 6 weeks, my recovery improved, my energy felt more stable, and I didn't have sleep issues like I did with pre-workouts."
"I've been lifting 5-6 days a week for years but started noticing it takes longer to recover in my mid-30s. After about 6 weeks on Flow, I'm recovering much faster — less sore with more energy going into my next session."
"I'm an older guy trying to stay active, and Flow has become a steady part of my routine. It feels like a real boost to circulation and stamina. Not a magic fix, but a helpful ally in keeping me moving strong as I age."
"I love beets and the flavor of Flow is great. I'm not able to take supplements with caffeine, and Flow gives me the pick-me-up I need without it."
Results that stack over time.
Flow is designed for daily use, working with your body's natural nitric oxide pathways to enhance circulation and restore optimal energy levels.*
Day 1 — Rapid Circulation Boost
Nitric oxide levels begin to rise within 1 hour, with improved blood flow continuing for up to 6 hours.*
Week 4 — Improved Recovery & Endurance
Tolerance for physical stress increases, allowing muscles to recover faster and perform longer.*
Week 8 — Enhanced Cardiovascular Support
Supports healthy blood pressure already within normal range and promotes long-term vascular health with ongoing use.*

FAQ

Most beet supplements use commodity beet root powder with no standardization or clinical research. Flow is built around Rednite® — a patented, standardized beet extract with published clinical research — combined with L-Arginine, seed-based extracts, Hibiscus, and a full B-vitamin complex. It targets nitric oxide through two distinct pathways.
Rednite® is a patented, standardized beetroot extract with published clinical research on nitric oxide production. Unlike generic beet root powder, Rednite® is standardized for consistency and potency — meaning a reliable dose every time.
Mix one packet with 8-12 oz of water and drink. Most people take it in the morning or 30-60 minutes before exercise for best results. Each box contains a 30-day supply.
Many people notice improved energy and endurance within the first week. For full circulatory benefits, we recommend consistent daily use for at least 30 days.
Flow is manufactured in a GMP-certified USA facility, third-party tested for purity and potency, and made with naturally-sourced ingredients.
