Does my teen athlete actually need supplements?
Sometimes. The 2026 National Athletic Trainers’ Association position statement backs a food-first but not always food-only approach. Food comes first because it is safer, cheaper and covers more ground, and no supplement fixes a plan that is short on calories, carbohydrate, fluid or sodium. Real gaps do exist: low iron or low vitamin D in bloodwork, no fatty fish in the week, a gut that never settles, or a schedule that makes five to six eating times impossible. Those are gaps the right product can close. The order is food, fluids, sleep and timing first, testing where it helps, then supplements chosen for a reason.

What supplements are best for a teenage athlete?
The best supplement is the one that closes a real gap. The five Dawn Weatherwax talks about most are a multivitamin and mineral, vitamin D3, omega-3 EPA and DHA, fiber and probiotics. The 2025 Dietary Guidelines Advisory Committee found fiber and vitamin D are under-consumed, and most people eat less seafood than recommended. These are categories, not prescriptions. Brands, amounts and timing are set for the individual athlete, and every product follows the same order: NSF Certified for Sport first, then Informed Sport or Informed Choice, then third-party tested when no certified version exists.

Is creatine safe for a high school athlete?
Creatine is one of the most studied supplements in sport and sits in Group A of the Australian Institute of Sport framework. The American Academy of Pediatrics has not recommended creatine for adolescents because of limited data, while the International Society of Sports Nutrition position stand says creatine monohydrate can be acceptable for adolescent athletes under specific conditions. That does not make it automatically right for a 14-year-old. The questions that come first: is your athlete eating and sleeping enough to grow, is the product NSF Certified for Sport or Informed Sport, what is the actual goal, and does the sport, school or governing body have rules about it. This is a decision to make with a sports dietitian who has seen your athlete's numbers, not from a teammate or a video. Read more: Is Creatine Right for Your Athlete?
Does my high school athlete need protein powder?
Usually not. Most athletes can reach their protein target with food when they eat five to six times a day. A powder earns its place when the schedule makes that impossible, when appetite is low, or when your athlete needs more total energy than they can chew. If one is used, look for NSF Certified for Sport first, then Informed Sport, then third-party tested, and the amount should be set on lean weight rather than total body weight, which is what body composition testing is for. Most athletes need only 14 to 28 grams at one time. A bigger athlete gets more protein from more eating times, not bigger scoops: in 14 to 18 year olds, the benefit per serving leveled off at about 0.30 grams per kilogram of body weight. Skip powders with added caffeine, creatine, herbal “boosters” or proprietary blends, because every extra ingredient adds risk for an athlete who is still growing or may be drug tested. A powder is a top-off, not a meal replacement. Read more: Protein Powders for Youth Athletes.
Are pre-workouts and energy drinks safe for teen athletes?
Energy drinks are not recommended here for athletes under 18. The National Federation of State High School Associations Sports Medicine Advisory Committee advises reminding athletes that energy drinks are not appropriate. Pre-workouts are different case by case. Most are multi-ingredient stimulant blends, and every added ingredient raises the odds of an accidental banned substance. If your athlete is reaching for one to get through practice, that is usually a fueling timing problem, and food and fluid timing come first. When a pre-workout is appropriate, Dawn's pick is Klean Pre-Workout by Klean Athlete: NSF Certified for Sport, with a small amount of caffeine at 75 mg per scoop. Its label is written for adults, so for athletes under 18 it is used only after a consult and with parent approval. Read more: Pre-Workout Supplements for Teen Athletes, and the caffeinated sports drink question.
How much caffeine is safe for a teen athlete?
The American Academy of Pediatrics advises no more than 100 mg of caffeine a day for adolescents and avoiding it under age 12. One 16-ounce energy drink can carry about 160 mg. The FDA does not require caffeine content on every label, so check products and add up coffee, soda, tea and energy drinks across the day. Caffeine’s performance research was done in adults.
Should my teen athlete take iron or vitamin D?
Only when bloodwork shows a need. Iron and vitamin D are two of the most common real gaps in training athletes, and both cost energy, recovery and bone health when they run low. Too much iron can cause harm, so iron is never a just-in-case supplement. Dawn Weatherwax reads labs against what a training athlete needs, because a value can sit inside the normal range and still be low for an athlete. For iron, the Gatorade Sports Science Institute lists three markers as the minimum: serum ferritin, hemoglobin and transferrin saturation, drawn in the morning after a rest day, fasted and hydrated. Bring any recent bloodwork to the consult.
Which certification is best: NSF Certified for Sport, Informed Sport or USP Verified?
NSF Certified for Sport comes first. In sports scientist Asker Jeukendrup’s 2026 comparison, three programs earn his top protection rating: NSF Certified for Sport, Informed Sport and BSCG Certified Drug Free. On the SN2Go gauge, only NSF gets a full tank. NSF is the only one that tests every batch, screens the most banned substances (290+), fully audits the factory and fully checks the label and contaminants. Informed Sport and BSCG are the next choices, then Informed Choice, which tests store-bought products periodically rather than every batch. USP Verified checks quality and label accuracy but is not banned-substance testing. No program checks whether a product works. When no certified version exists, which happens with some single vitamins like B12, a third-party tested product is vetted one by one.
How do I check if a supplement is really third-party tested?
Look up the exact product in the certifier's own database. Do not trust the label. For NSF Certified for Sport, search the NSF Certified for Sport app or nsfsport.com. For Informed Sport, search the product and its batch number at sport.wetestyoutrust.com, because Informed Sport certifies by batch. USADA has warned that certification logos have appeared on products that were not certified, so a logo alone proves nothing. If a product claims a certification but the product, or the batch in your hand, is not listed, do not trust the claim. Some nutrients, like vitamin B12, often have no certified version at all, and those products are vetted one by one.
Could a supplement cause a failed drug test?
Yes. Under anti-doping rules, athletes are responsible for anything in their system, however it got there. A 2026 systematic review of 44 lab studies found that about 9 to 15 percent of supplements bought off the shelf contained banned or unapproved substances not on the label, most often stimulants and anabolic agents, including SARMs. Use NSF Certified for Sport first, then Informed Sport, check the batch, keep a photo of every label and batch number, and never share supplements.
What does OHSAA say about supplements?
The Ohio High School Athletic Association Board of Control endorses the National Federation of State High School Associations position statement on drugs, medicine and food supplements. It says school personnel and coaches should not dispense any supplement except with extreme caution and under school policy, and should never supply, recommend or permit supplement use solely to enhance performance. That is why families bring supplement decisions to a sports dietitian. Source: ohsaa.org, Sports Medicine, Nutritional Supplements.

My athlete is tired all the time. Will a supplement fix that?
Usually not first. Constant tiredness in a training athlete most often comes back to under fueling or misfueling: not enough energy, carbohydrate or fluid for training and growth, or the wrong timing. That is a food and timing fix before it is a bottle. Metabolism testing and a muscle fuel scan show whether the tank is actually empty, and bloodwork can show whether iron or vitamin D is low. USA's #1 Fueling Expert, sports dietitian Dawn Weatherwax, RD, LD, LAT, ATC, CSCS, reads all of it together in a paid consult at Sports Nutrition 2Go.
A coach or teammate recommended a supplement. What should I do?
Do not start it yet. Look up the exact product and batch in the NSF Certified for Sport or Informed Sport database, and read the label for caffeine, stimulants and proprietary blends. The position statement OHSAA endorses says coaches and school staff should never supply, recommend or permit supplements solely to enhance performance. Bring the bottle to a paid consult at Sports Nutrition 2Go, and Dawn will tell you whether to keep it, change it or drop it.
What are the red flags on a supplement label?
Put it back if you see any of these: “third-party tested” with no program named; “WADA approved,” because WADA does not approve products; a certification logo that is not in the certifier’s database; “proprietary blend”; claims like boosts testosterone, burns fat, toning or research chemical; stimulants such as DMAA, DMHA (octodrine), higenamine, BMPEA or synephrine; or any SARM, such as ostarine or RAD-140. A 2026 review of 44 lab studies found contamination most often in pre-workout, weight-loss and muscle-building products.
19. Is it safe to buy my athlete's supplements on Amazon?
You cannot always tell who sold a bottle on a third-party marketplace or how it was stored. Fullscript lists only authentic products obtained directly from the manufacturer, requires every brand to prove third-party cGMP certification each year, and ships from NSF-certified facilities. Access is by invitation from a health professional whose credentials Fullscript has verified, and Sports Nutrition 2Go's invitation is free for now. Whatever the store, check the product in the certifier's database.
Is creatine a steroid?
No. Creatine is an amino acid derivative, not a hormone, and it does not raise testosterone. Your body already makes it, and athletes already eat it in red meat and fish. It is not banned by any sport organization, and the Australian Institute of Sport places it in Group A, its top evidence group. Whether your athlete should take it is a separate question, answered in a paid consult.
Can athletes get results without supplements?
Yes. Results come from food, timing and testing first, not from a bottle. Luke Kuechly started nutrition and testing with Dawn Weatherwax as a sophomore at St. Xavier, went from 170 to 238 lb at 10% body fat, then played at Boston College and in the NFL. Devin B. gained 10 lb of lean weight in 10 months and went on to play college basketball. Jacob Smith gained more than 40 lb and played college lacrosse. Heidi H. went from low energy to PRs and top state finishes in cross country and indoor track. When a supplement was used, it came last, for a real gap, and was checked first. These are standout results, and results vary by age, growth, training phase and effort. See more athlete stories on the Sports Nutrition 2Go testimonials page.
