Kite trip, day four: the wind fills in at eleven, you ride until three, eat a bag of chips in the shade, go back out until sunset and then realize you never had lunch. Wind sports make it easy to under-eat: you’re waiting for wind, then you’re riding, then it’s dark. This page is a short guide to nutrition for kitesurfers: what to eat day to day, how to fuel windy weeks, downwinders and race days, and which supplements are worth a look, with the safety rules first.

General information, not medical or dietary advice. Talk to a doctor or registered dietitian before starting a supplement, especially if you’re under 18, pregnant, have a heart, kidney or other health condition, or take medicines. Prices change often; the prices below are what we saw at the maker or a major retailer in October 2026. Back to the kitesurfing hub. Windsurfers have their own page: windsurfing nutrition.

What the research says

No nutrition study or consensus is specific to kitesurfing yet, but the effort studies give a clear picture. Recreational kitesurfers rode at about 78% of maximum heart rate over 40 to 50 minutes in a 2026 study, and elite riders on a 30-minute crossing held about 81% with low blood lactate: steady aerobic work, session after session. Jumping and racing add short, hard efforts on top. A windy week can mean several hours on the water a day, so the main risk for kiters is simply not eating and drinking enough. The best guide is general sports nutrition from the American College of Sports Medicine (ACSM), the Academy of Nutrition and Dietetics and Dietitians of Canada.

Everyday eating for riders

• Carbohydrate for riding days. ACSM scales it to training: about 3 to 5 g per kilogram of body weight a day for light days, 5 to 7 g for about an hour a day of moderate exercise and 6 to 10 g for 1 to 3 hours a day. A windy week with long sessions is a high-fuel week: rice, pasta, potatoes, bread, oats, fruit.
• Protein for legs, back and landings. ACSM suggests 1.2 to 2.0 g per kilogram a day, spread through the day, and about 15 to 25 g after a session. For a 70 kg rider that’s about 85 to 140 g a day from eggs, fish, meat, beans, yogurt, milk or tofu.
• Calcium and vitamin D. Dairy or fortified alternatives, leafy greens and oily fish. Sunscreen, rash guards and wetsuits (all good ideas) mean a sunny sport doesn’t guarantee enough vitamin D; ask your doctor whether a blood test makes sense.
• Fluids and salt. Drink before and after, and between runs on long sessions. Timing is on the Session Day and Race Day page.
• Pack food. A cooler with sandwiches, fruit, rice cakes and yogurt beats the beach kiosk on long days.

Fueling windy weeks, downwinders and race days

• Before you ride: a familiar meal 1 to 4 hours before, with carbohydrate and not too much fat or fiber (ACSM): oatmeal with fruit, toast and eggs, or a rice bowl.
• Long sessions and race days: ACSM and the IOC consensus suggest about 30 to 60 g of carbohydrate an hour for 1 to 2.5 hours of stop-and-go exercise. Between runs or races that’s a banana and a handful of dates, a jam sandwich, or a bottle of sports drink.
• Waiting for wind: race days and kite days often mean hours on the beach. Eat a real lunch while you wait instead of skipping it.
• Downwinders: you can’t come back to the beach for a snack halfway. Eat well beforehand, and on long runs carry a soft flask or gel in a vest pocket and keep a drink and food waiting at the finish.
• Evenings: a full dinner with carbohydrate, protein and vegetables refuels you for the next day. On trips, alcohol and late nights hurt the next session more than most riders admit.
• Cold-water days: warm drinks and a hot meal after the session help you warm up.

Teen riders need enough total food to grow and ride. A UEFA expert statement on young athletes says general use of supplements should be restricted; food comes first. The American Academy of Pediatrics says energy drinks have no place in the diets of children and teens, and recommends against creatine for young athletes.

Supplements: the safety rules first

• Food first. The International Olympic Committee’s consensus statement says only a few supplements have good evidence (caffeine and creatine among them).
• Contamination is real. In an analysis of 634 supplements from 13 countries, about 15% contained undeclared steroid precursors that could cause a positive test.
• Choose third-party tested products (NSF Certified for Sport, Informed Sport or Informed Choice). They lower the risk but don’t remove it.
• Drug testing. Formula Kite has been an Olympic sailing event since Paris 2024 and is on the LA28 program, and national-team and international riders can be tested under the World Anti-Doping Agency (WADA) Code. You’re responsible for everything you take.
• Nothing banned. No DMAA, SARMs or prohormones, no proprietary blends that hide doses; never exceed the label.

Supplements riders commonly use, compared

Product	In one serving	Certification	About (Oct 2026)	Per serving
Nuun Sport	300 mg sodium, 150 mg potassium, 1 g sugar	Informed Choice (maker)	$7.49 / 10 tablets (maker)	about $0.75
Skratch Labs Hydration	400 mg sodium, about 20 g carbs	NSF Certified for Sport (maker)	$23.95 / 20 servings	about $1.20
Thorne Whey Protein Isolate	21 g protein	NSF Certified for Sport	$65 / 30 scoops	about $2.17
Thorne Creatine	5 g creatine monohydrate	NSF Certified for Sport	$44 / 90 scoops	about $0.49
Klean Multivitamin	2 tablets; 1,000 IU vitamin D; no iron listed	NSF Certified for Sport	about $46 / 30 servings	about $1.53

Electrolytes are the most useful extra on hot or long days; Nuun Sport is low in sugar, and Skratch Labs adds carbohydrate. Protein powder such as Thorne Whey Protein Isolate is handy on trips where protein is hard to find. Creatine is one of the most studied supplements for strength work in the gym; some adults gain 1 to 2 kg, mostly water, and it isn’t for under-18s per the AAP. A multivitamin such as Klean Multivitamin is a safety net, not a performance aid. Caffeine is well studied too, but it can cause jitters, a racing heart and poor sleep; anyone with a heart condition, who is pregnant or sensitive should check with a doctor first, and kids and teens should skip energy drinks.

Kitesurfing nutrition: FAQs

What should I eat before kitesurfing?

A familiar meal with carbohydrate 1 to 4 hours before, low in fat and fiber (ACSM), such as oatmeal with fruit, toast and eggs or a rice bowl. Bring a snack for between sessions.

Do kitesurfers need supplements?

Most don’t. Food covers the basics; electrolytes on hot, long days are the most useful extra. If you choose any supplement, pick a third-party tested one and check with a doctor or dietitian.

Are Olympic kitesurfers drug tested?

Yes. Formula Kite is an Olympic sailing event, and riders at that level can be tested under the WADA Code. Third-party tested supplements lower, but don’t remove, the risk of a positive test.

Is creatine OK for teenage riders?

The American Academy of Pediatrics recommends against performance-enhancing supplements such as creatine for young athletes. Food, sleep and good training come first.
