Fewer niggles.More miles.
A daily collagen and vitamin C formula for runners who want to keep stacking the miles.
Core formulaCollagen + Vitamin C
DailyOne scoop, any drink
Runners rarely stop because they're unfit. They stop because something niggles.
A tight Achilles. A grumbling knee. Shins that won't settle after a big week.
Mileproof is one part of a routine for runners who want to stay consistent: sensible mileage, strength work, proper sleep and one scoop a day.

The formula
Built on two things your tendons know.
Nothing clever for the sake of it. A short, focused formula you take every day, with the full ingredient list and amounts printed on every pack.
Vitamin C
The partner nutrient. It's why collagen and vitamin C go together.
Vitamin C contributes to normal collagen formation for the normal function of cartilage.
Made for every week of the block
One scoop a day, through the build weeks, the cutbacks and the taper. Full formula and amounts come with your recommendation.
Step 01One scoop.
Measured, quick, done. No pill organiser needed.

Water, coffee, a smoothie or your post-run shake.
Step 03Every day.
Rest days included. Consistency is the whole point.

FAQ
Straight answers.
Why do I need a consultation?
Because we'd rather sell Mileproof to runners it suits than to everyone. A quick consultation lets us check your training, any niggles and anything you're already taking before you order.
How long does it take?
The form takes about two minutes. We read every one personally and reply by email with your recommendation and a private order link.
What's in it?
Hydrolysed collagen and vitamin C are the core. You'll get the full formula and amounts per serving with your recommendation, and they're printed on the pack.
How do I take it?
One scoop a day in water, coffee, a smoothie or a post-run shake. It's built to be a daily habit, so take it every day of your block, not only after the hard sessions.
I've already got an injury. Will Mileproof fix it?
No supplement fixes an injury. If something hurts, get it looked at by a physio or your GP. Mileproof is for the everyday routine, alongside sensible training.
Is it vegan?
No. Collagen comes from animal sources, so Mileproof isn't suitable for vegans or vegetarians. The exact source will be on the pack.
Who's behind Mileproof?
Mileproof is a Highform brand. Highform Ltd is a UK company building specialist supplements for runners and endurance athletes.
Where do you deliver?
We deliver across the UK.
