Water
Replaces fluid, but does not replace the electrolytes lost through sweat or provide broader performance support.
How DF-18 works
One stick.
Four systems.
All 18.
Most drinks solve one problem. A round of golf demands more.
DF-18 is a caffeine-free, sugar-free pre-round formula built to support four connected systems: hydration, energy, focus, and recovery.
One serving before the first tee. Support through the final putt.

Golf is an endurance sport
It just doesn’t look like one.
A round lasts four to six hours. You are walking, sweating, making hundreds of decisions, and repeating a precise movement under pressure.
As fluid levels fall and fatigue builds, the effects show up in familiar ways: heavy legs, inconsistent tempo, poor decisions, and shots you normally would not make.
Most golfers call it the back nine.
DF-18 was built to help you remain more consistent through it.
Four systems. One formula.
Your body doesn’t fade one system at a time.
Hydration, circulation, physical output, mental performance, and recovery do not operate independently.
When hydration slips, muscles and concentration can follow. When physical strain rises, maintaining composure becomes harder. What happens during the round also influences how you feel afterward.
That is why DF-18 is built as a connected formula rather than around one “hero” ingredient.
01
Hydration
Make the water you drink work harder.
Drinking water and staying hydrated are not the same thing.
During a long round, your body needs electrolytes to maintain fluid balance and normal muscle function. DF-18 combines sodium, potassium, and magnesium with glycerol to provide broader hydration support than water alone.
Why glycerol matters
Electrolytes help maintain fluid balance. Glycerol helps your body retain more of the water you drink, giving that hydration greater staying power as the hours add up.
- 590mg sodium
- 700mg potassium
- 200mg magnesium
- 1g glycerol powder
What that means on the course: Hydration and normal muscle function supported beyond the opening holes—especially during long walks and hot conditions.

Energy
Energy without borrowing from the back nine.
Caffeine can create a noticeable lift. But golf rewards composure and consistent output for several hours—not a dramatic change in state.
DF-18 approaches energy by supporting the systems beneath performance, including circulation and normal energy production.
Each serving provides 400mg of dietary nitrate from beet root and sodium nitrate. Dietary nitrate supports nitric-oxide production and healthy blood flow, helping your body continue moving oxygen and nutrients where they are needed.
Unlike a temporary stimulant lift, the nitrate pathway develops progressively and remains relevant across a multi-hour effort.
The objective is not to push you above your baseline. It is to help you remain closer to it as the round progresses.
- 400mg total dietary nitrate
- Beet root
- Agmatine
- Aronia berry
- Vitamin C
Golf does not reward the biggest spike.
It rewards the smallest drop-off.
What that means on the course: Support for stamina, tempo, and physical output without relying on caffeine or sugar.

Focus
Calm is a performance advantage.
Golf does not reward frantic energy. It rewards clear decisions, controlled tempo, and commitment when the shot matters.
DF-18 uses a caffeine-free focus layer to support steady attention during prolonged physical and mental demand. L-theanine supports a calm state, while tyrosine supports cognitive performance under stress.
That focus layer works alongside the hydration and circulation systems. After all, no focus ingredient can fully compensate when fluid balance and physical performance begin to deteriorate.
- L-theanine
- N-acetyl-L-tyrosine
- Theobromine
- goBHB®
- Ashwagandha
The goal is not to manufacture an intense feeling of focus.
It is to help preserve the focus you started with.
What that means on the course: Support for clearer decisions, steadier tempo, and sustained concentration through the closing holes.

Recovery
Recovery starts before the round ends.
Recovery is influenced by what accumulates while you play: fluid loss, muscular demand, heat, time on your feet, and sustained concentration.
By supporting hydration, circulation, muscular function, and mental composure during the round, DF-18 also supports the recovery process that follows it.
NAC and vitamin C provide antioxidant support. Magnesium supports normal muscle function, while B vitamins support normal energy metabolism.
- NAC
- Vitamin C
- B-vitamin complex
- Magnesium
- Circulation support
Your round ends on 18.
Your day usually does not.
What that means after the course: Support for normal recovery and for whatever comes next—another round, a workout, or the rest of your day.

Built for the next five hours—not the next five minutes.
Most drinks are not bad products. They were simply designed for different jobs.
Electrolyte and sports drinks
Help replace fluid and minerals. Some also supply carbohydrates for fuel, which can be useful when the activity requires them.
Coffee and energy drinks
Create a noticeable lift through stimulation. They are not designed to provide complete hydration, circulation, and recovery support.
Pre-workout
Typically built for a shorter, concentrated training session and often formulated around stimulants or ingredients that depend on consistent use.
DF-18
Built specifically to support hydration, sustained energy, calm focus, and recovery across a four-to-six-hour round—in one pre-round serving.
DF-18 does not try to make the first three holes feel extraordinary.
It is built to keep the last five from feeling different.
Beyond golf
Built for golf. Not limited to it.
Golf gave DF-18 its original design problem: support the body and brain through four to six hours of movement, heat, repetition, and sustained decision-making—without relying on caffeine or sugar for a temporary change in state.
But those demands are not unique to golf.
Training, travel, outdoor activity, and long workdays depend on many of the same systems: hydration, circulation, energy production, muscular function, mental composure, and recovery.
Golf was the proving ground—not the limitation.
Sustained effort
Support built for the hours ahead.
Many pre-workouts are designed to feel powerful before the workout begins. DF-18 is designed to remain useful after it does.
Ingredients such as creatine and beta-alanine can support performance, but their primary benefits depend on consistent use and accumulation over time. DF-18 focuses on what one serving can support during the effort in front of you.
Its 400mg of dietary nitrate supports nitric-oxide production and healthy blood flow through a pathway whose time course is particularly well matched to sustained effort. Electrolytes and glycerol support hydration, while the surrounding formula supports circulation, steady mental engagement, muscular function, and recovery.
The objective is not to make the first 20 minutes feel extraordinary. It is to help the next several hours remain productive.
Performance support
Performance support is not the same as fuel.
DF-18 contains no sugar and is not a source of carbohydrate fuel.
That gives you control over how—and whether—you add calories for the activity ahead. For prolonged or high-output exercise, pair DF-18 with the carbohydrates, protein, and total nutrition the effort requires.
DF-18 supports the systems performing the work. Food still supplies the fuel.
Present-day capacity
Built for what your body needs today.
Some nutrition products are designed to help fill dietary gaps over time. DF-18 serves a different purpose.
It supports present-day capacity: hydration, circulation, energy production, focus, muscular function, and recovery during the hours directly in front of you.
That could mean an 18-hole round, a workout, a hike, a long day outside, or hours of travel, meetings, and family commitments.
One formula. More than one kind of demanding day.
Long-term health matters. So does how well you can use the day you are in.
Beyond the course: DF-18 is a daily performance formula for physical and mental demands that last longer than a quick burst.
- 400mg dietary nitrate
- Full electrolyte profile
- Glycerol
- Agmatine
- Tyrosine
- L-theanine
- goBHB®
- NAC
How to use DF-18
One serving before the first tee. That’s it.
Mix one stick pack into 16–20 oz of cold water approximately 30–45 minutes before your round.
Sip it as you prepare for tee time or through the opening holes. Continue drinking water during the round according to the heat, your sweat rate, and whether you are walking or riding.
Beyond golf, take one serving approximately 30–45 minutes before training, prolonged outdoor activity, or another physically or mentally demanding part of your day.
- No mid-round redosing
- No supplement stack to remember
- No caffeine timing to manage
Full-label transparency
Every ingredient. Every dose. No proprietary blend.
DF-18 contains 25 ingredients selected to support four connected systems. Many work across more than one system because hydration, circulation, focus, and recovery overlap inside the body.
Every ingredient and its exact dose is published so you can evaluate the complete formula for yourself.

What should I expect?
What should I expect to feel?
DF-18 is not designed to create a stimulant buzz.
Some golfers notice steadier focus early. Others notice the absence of their usual back-nine drop: less fog at the turn, fewer heavy moments late in the round, or more consistent tempo through the closing holes.
The clearest test is not how you feel five minutes after drinking it. It is how you feel standing on the 18th tee.
Is DF-18 just an electrolyte drink?
No. Electrolytes are one part of the formula. DF-18 also includes ingredients selected to support circulation, sustained energy, focus, muscular function, and recovery.
Does it contain caffeine or sugar?
No. DF-18 is caffeine-free and sugar-free.
Do I still need to drink water?
Yes. DF-18 supports hydration; it does not replace the water your body needs. Continue drinking according to the conditions and your individual sweat rate.
Can I use DF-18 when I’m not playing golf?
Yes. DF-18 was designed around the demands of an 18-hole round, but its hydration, circulation, focus, muscular-function, and recovery support are relevant to training, outdoor activity, travel, and other demanding days.
