NORTHLINE PERFORMANCE
OUR
STORY.
Thirty-five years of fuelling athletes from first finish lines to world podiums. This is where it started.

FOUNDER & HEAD OF SPORTS SCIENCE
DR. MARCUS
THORNE
A competitive marathon runner and exercise physiologist, Dr. Thorne founded NorthLine in 1989 after years of frustration with under-dosed, over-sweetened gels that crashed his performance at mile 18.
His philosophy is simple: every formula must survive a race, not just a lab test. Thirty-five years later, that standard drives every product we make.
"Real athletes don't need magic. They need the right substrate at the right moment."
WHAT WE STAND FOR
GOLD STANDARD
PRINCIPLES
Science First
Every formula is grounded in peer-reviewed sports science. We cite our sources — internally and on our label. No proprietary blends, no hidden dosing.
Race-Tested
Lab results mean nothing if a product fails at km 30. Our athletes test prototypes in real race conditions before anything reaches production.
No Shortcuts
We manufacture in-house. We control every step from raw ingredient sourcing to batch testing. If it doesn't meet the standard, it doesn't ship.
