Ingredients
What's in DF-18 — all 25 ingredients, every dose disclosed.
DF-18 isn't a typical hydration drink, energy drink, or greens supplement. It's built for the specific demands of a 4–6 hour round on foot — by supporting the four systems that quietly degrade over 18 holes. No proprietary blends. Every ingredient and its exact dose is listed below.
Built as a stack. Not a shopping list.
Most brands lead with whatever ingredient markets best, then build around it. DF-18 was formulated the other way — backward, from the four things that fade over a 4–6 hour round to the ingredients that hold them. A few actives get you started. Most of the rest pull double or triple duty across systems, so nothing quietly drops off as the hours add up. There's no hero ingredient. There's a stack.
Set you up
Acute actives that help you feel switched-on early. Most do one job well — and that's the job. They start the round; they don't finish it.
Keep you there
The multi-duty stack. Each supports several systems at once, so hydration, stamina, focus and recovery don't degrade across the back nine.
Not more focused. Consistently focused.
Ask a golfer why DF-18 felt different and they'll often say 'more focused.' Press a little and it's something more specific — they felt focused the whole way through, with no back-nine fog. That's less a nootropic doing more, and more hydration and circulation keeping the brain from doing less. A nootropic can't clear fog the body creates when it's running low on fluid and flow.
Hydration — retention, not just volume
Electrolytes dosed for a full 4–6 hour round, plus glycerol to support fluid retention — helping protect against the dehydration and cramping that show up across the back nine.
Why these work together
Golf hydration isn't just 'more salt.' Proper electrolyte ratios help fluids stay in circulation, support smooth muscle function, and reduce the likelihood of cramping or tension building over a 4–6 hour round — the difference between finishing strong and grinding through the back nine.
Circulation & nitric-oxide support — energy and stamina
Multiple complementary nitrate sources support nitric-oxide pathways — the delivery efficiency behind steady energy and tempo on the closing holes.
Why this matters on the course
Nitric oxide helps blood vessels respond and relax efficiently, supporting smoother delivery of oxygen and nutrients — especially on the long walk and hot afternoons. This supports a 'less flat' feeling on 15, 16, 17, 18, when energy usually drops off.
Calm focus & stress-buffering — no caffeine
The kind of focus golf actually rewards — calm and steady — without stimulants that bring jitters into your swing.
Why this feels different on the course
Instead of pushing the nervous system the way a caffeinated energy drink does, this stack helps reduce background stress and tension, so your focus stays steady and controlled from your first tee shot to your last putt.
Recovery & cellular resilience
Foundational support — not stimulation — so the round you played Saturday doesn't decide how you feel Sunday.
Why this matters for golfers
When hydration, circulation, and stress are better managed across a round, the body tends to accumulate less recovery debt — which matters most if you're walking 18 several times a week, playing a multi-day event, or backing up a round with a long day of lessons.
One label. Read it sideways.
Every active, and which of the four benefits it supports. Bright dot = the job it's primarily there for; softer dot = a system it also supports; no dot = no claim. The pattern is the point: the sustaining actives keep crossing columns.

Seven of the sustaining ingredients each support three or more of the four systems. That's what 'earns its place in the stack' means — measured, not asserted.
