Water Ski Nutrition and Supplements

It’s 5:30 a.m. in a hotel room near the ski site. Slalom at 7, tricks around 10, jump after lunch if the wind holds. What goes in the cooler today matters as much as the ski in the bag. And on an ordinary summer Saturday, the boat crew that packs real food skis better at 4 p.m. than the one living on chips. This page covers nutrition for water skiers: everyday eating, what to eat on the boat and at tournaments, and an honest look at supplements, for kids, college skiers, tournament athletes, show skiers and weekend crews.

General information, not medical or nutrition advice. Talk to your doctor or a registered dietitian (a board-certified sports dietitian, CSSD, if you can) before starting any supplement, especially if you have a health condition, take medication, are pregnant, or are under 18. Prices change often; the prices below are what we saw at the maker or a major retailer in October 2026. Back to the water skiing hub.

What water skiers need

There’s no water ski-specific nutrition research to speak of, so the guidance comes from the joint position of the American College of Sports Medicine (ACSM), the Academy of Nutrition and Dietetics and Dietitians of Canada. Water skiing is short bursts of hard work (a pass through the 259-meter slalom course takes well under a minute; a trick pass is 20 seconds) spread over a long day outdoors, plus strength work on land. That means:

• Carbohydrate for energy: ACSM’s ranges run from about 3 to 5 g per kilogram of body weight a day for light training up to 5 to 7 g for moderate training and 6 to 10 g for heavy endurance work. Most recreational skiers sit at the low end; college and tournament skiers in heavy training a bit higher.
• Protein for muscle repair: about 1.2 to 2.0 g per kilogram a day, spread through the day, with 15 to 25 g after hard sessions. For a 70 kg skier that’s roughly 85 to 140 g a day.
• Fluids and salt for long, hot days on the water (more on our Tournament Day page).

An everyday plate

Nothing fancy: a protein at each meal (eggs, chicken, fish, beans, Greek yogurt, tofu), a carb that suits the day’s work (rice, pasta, potatoes, bread, oats, fruit), plenty of vegetables, and some healthy fat. On training days add a carb-rich snack before the session and a protein snack after. On rest days, ease off the extra carbs.

On the boat and at tournaments

• Breakfast 1 to 4 hours before your first pass (the ACSM window): oatmeal with banana, a bagel with peanut butter, eggs on toast, or yogurt and granola. Keep it familiar; tournament morning is not the time for new foods.
• A cooler, not a snack bag: sandwiches or wraps, fruit, pretzels, granola bars, trail mix, cheese sticks, yogurt, plenty of water.
• Small and often between events or turns, every hour or two. Save big meals for long breaks.
• Electrolytes on hot days for heavy, salty sweaters.
• After the last pass: carbs plus protein, like a turkey sandwich and chocolate milk. Our recovery page has more.

Kids, teens and female skiers

Kids and teens need enough total food to grow and ski. A UEFA expert statement on nutrition in young athletes says supplement use should be restricted: food first, and any supplement decided with a doctor or sports dietitian. The American Academy of Pediatrics (AAP) says energy drinks have no place in the diets of children and adolescents, and recommends against creatine and other performance-enhancing substances for young athletes. Female skiers have higher iron needs; the same UEFA statement recommends iron checks and warns that routine iron supplements without a test can do more harm than good. More on young skiers on our youth page.

Supplements: what’s worth a look

• Food first. The International Olympic Committee’s consensus statement on supplements says only a few have good evidence for performance (caffeine and creatine are among the better studied), and many have none.
• Third-party testing matters. The US Anti-Doping Agency (USADA) warns that dietary supplements can be risky because they’re regulated after they reach the market, so a product isn’t pulled until there’s proof it has harmed people. In one large lab study, about 15% of 634 supplements from 13 countries contained prohibited substances not on the label. Look for NSF Certified for Sport or Informed Sport/Informed Choice.

Product	In one serving	Certification	About (Oct 2026)	Per serving
Nuun Sport	300 mg sodium, 150 mg potassium, 1 g sugar	Informed Choice (maker)	$21.05 / 4 tubes of 10 tablets	about $0.53
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

• Electrolytes are the most useful “supplement” for a long, hot lake or tournament day. Nuun Sport is low in sugar; Skratch Labs Hydration adds carbohydrate for long days. See best electrolyte powders.
• Protein powder is a convenience when food isn’t practical, not a must. Thorne Whey Protein Isolate has 21 g protein per scoop. See best protein powders.
• Creatine is one of the most studied supplements; many adult athletes take it to support strength training, which suits off-season gym work for legs, back and grip, though there’s no water ski-specific research. Some people gain 1 to 2 kg, mostly water. Thorne Creatine is plain creatine monohydrate. Not for under-18s, per the AAP. See best creatine.
• Caffeine: many adults drink coffee before an early start, and it’s one of the better-studied supplements. It can cause jitters, a racing heart, stomach upset and poor sleep (bad news before day two of a tournament); people with heart conditions, those who are pregnant or sensitive should check with a doctor. Check the caffeine per serving on any pre-workout or energy drink, and skip them for kids and teens.
• Skip anything promising fat loss, “test boosting” or miracle recovery, proprietary blends that hide doses, and anything banned in sport.

Anti-doping for competitive skiers

The International Waterski & Wakeboard Federation (IWWF), the world governing body, publishes anti-doping rules and therapeutic use exemption (TUE) forms for athletes who need a prohibited medication. USADA notes that TUEs aren’t granted for supplements and that any supplement is taken at your own risk. If you ski at international level, check your medications and supplements well before competing and use third-party certified products. For how the sport is organized, see our leagues and associations page.

Fuel for land training is on the training page. Wakeboarders have their own page: wakeboarding nutrition. For a team-sport version, compare soccer nutrition.

Water ski nutrition: FAQs

What should I eat before water skiing?

A familiar meal with carbs and some protein 1 to 4 hours before, such as oatmeal with banana, a bagel with peanut butter, or eggs on toast, plus fluids. If you only have an hour, keep it small: a banana or a granola bar.

What should I eat during a water ski tournament?

Small, easy snacks every hour or two between events (fruit, pretzels, granola bars, half a sandwich), water, and electrolytes on hot days. Keep larger meals for long breaks, at least an hour before your next pass.

Do water skiers need protein powder?

No. Most skiers can reach about 1.2 to 2.0 g of protein per kilogram a day from food. Powder is a convenience; if you use one, pick a third-party certified product such as NSF Certified for Sport.

Is creatine OK for teenage water skiers?

The American Academy of Pediatrics recommends against creatine and other performance-enhancing supplements for young athletes. Teens should focus on food, sleep and training, and talk to a doctor before any supplement.

Are electrolyte drinks worth it for water skiing?

On long, hot days, especially for heavy or salty sweaters, they can help you replace sodium along with water. On a short, cool session, water and normal meals are usually enough.
