Inside DF-18

More behind every round.

Five electrolytes are only the beginning. Explore the ingredients behind hydration, circulation, calm focus, and everyday health.

Electrolyte & Hydration Foundation

5 electrolytes + glycerol

Keep your body in the game.

Sodium, potassium, chloride, magnesium, and calcium bring together support for fluid balance, working muscles, and nerve function. Paired with glycerol to round out the hydration formula.

590 mg Sodium · 700 mg Potassium · 900 mg Chloride · 200 mg Magnesium · 310 mg Calcium

Hydration · Muscle function · Nerve support

Circulation & Nitric-Oxide Support

400 mg dietary nitrate

Support the flow behind your performance.

Dietary nitrates support your body’s nitric-oxide pathway, which helps regulate blood flow. DF-18 pairs its nitrate sources with vitamin C, NAC, aronia berry extract, and agmatine, bringing circulation and antioxidant ingredients together.

Calm Focus & Composure

200 mg L-theanine

Find your focus. Keep your composure.

Golf asks as much of your mind as your body. Featuring L-theanine alongside N-acetyl-L-tyrosine, goBHB®, ashwagandha, theobromine, and choline—a caffeine-free approach to the focus and mental demands of the game.

Reviews

DF-18 Golf Energy Drink

"I am very happy to have found a product that addresses my cramping situation. I could not understand what was happening to me after golf, especially in the hot weather, until I found the explanation on the DriveForce web site. I ordered DH-18 and used it for the first time this week. Even though the weather was not extremely hot, I could tell a difference especially in my energy and focus levels on the back nine. I will definitely use it playing golf."

— Anna S. (5/5)

GOOD STUFF

"DF-18 is really "good stuff. " Helps me to get thru those last 4+ holes when my 78 year old body seems to want to call it a day."

— THOMAS V. (5/5)

Sample pack order

"I ordered and paid for 2 sample packs, I only received one. Although I am satisfied with the product it worked as advertised."

— Scott C. (4/5)

Driveforce

"I will admit I've used it my last three rounds of golf and it has really helped. Ive stayed focused. Ive had energy. Played some of my best golf."

— Rodney M. (5/5)

This product actually works

"I used this product 2 times while golfing so far and I really can't imagine golfing without it now. I had more energy and focus throughout the round and even after I got home. This product works!"

— John W. (5/5)

High Humidity - - No Problem

"At this time of year, it gets hot with humidity levels 90% or higher. In the past, I'd run out of energy and focus halfway thru the back 9. Not anymore! DF-18 has kept me moving and grooving until the end of my round. At 78 years old, this has not only increased my focus and energy but it has also increased my joy for playing this tough sport."

— Tommy G. (5/5)

Best hydration drink out there.

"This product is the absolute best, I've been a repeat customer for awhile. I really notice the difference from the first time I used it for hydration, fatigue, I use to feel fatigue on 11th hole before, not while drinking this. Could play 36 and feel great. Thank you so much for a great product. Will never be without it."

— Jeffrey R. (5/5)

It Works!!!

"You can actually feel yourself staying focused but relaxed."

— Sezzle C. (5/5)

"Well I am very surprised. Ive tested it out on several rounds and there actually is a definite improvement. I will see about get more."

— Keith (5/5)

18 holes is not 14 holes

"Drive force keeps me energized and focused through ALL 18 holes. I notice zero dropoff towards the end of the round which often happens when NOT using Drive Force"

— David L. (5/5)
