Honey base
47 sugars vs. 2.
Most gels are built on two carbohydrate sources, usually maltodextrin and fructose. N47 is built on honey: a broad mix of sugars, absorbed at different rates.

Athlete notes
Tested on real runs.
Three Copenhagen runners took N47 on tempo runs and long runs. Their notes, unedited.

"Single-use gels can be tricky to open mid-run. It took a run or two to get used to the flask, but after that it felt more natural. No GI issues and I liked the honey flavour."
"I really struggle with thick gels, so the almost drinkable consistency is perfect for me. It's easy to get down mid-run. It tastes natural, mostly honey with a touch of salt, and doesn't get too sweet or overwhelming."

"Tested it on an 18 km tempo run. Significantly better experience than any gel I've tried. The flasks are replacing my gels for the build-up to my trail race in Norway."
Founder · Bjarke Rasmussen
"So I started bringing a tube of honey instead. No packaging, no ingredient list. Just honey. It worked just as well, and my gut stopped complaining."

We reply within 2 business days.
Does honey cause GI issues like other gels?
Many GI issues come from a high dose of one or two sugars hitting the gut at once. N47 is built on honey, with 47 natural sugars absorbed at different rates, so the load is spread out. Every gut is different, so try it on long runs before race day.
How much is in one N47 bottle?
One N47 bottle holds 14 gels: 420 g of carbohydrates. That fills your Gel Flask about three times. A typical marathon uses around half a bottle.
How does N47 taste?
Like honey, but not as sweet as you'd expect. Dextrose shifts the sugar profile, and electrolytes and citric acid balance it out. Mild, slightly tart, easy to get down at km 30.
How does the Gel Flask work?
Fill it from your N47 bottle, bite the valve, squeeze. No cap, one hand. It holds 150 ml, about 4.5 gels. Rinse with warm water and soap after use and let it dry with the cap open.
Why is there a preservative in N47?
A small amount of potassium sorbate keeps N47 fresh once opened. Minimum 4 months shelf life at delivery.
What if it's not for me?
Unused items can be returned within 30 days. Opened gel can't be returned for hygiene reasons. If something is wrong with your order, write to us and we'll make it right. Full refund policy
