The Top Evidence-Based Supplements for Every Athlete – Caitlin Wells Pharmacist, Certified Sport Nutrition Coach
Whether you’re training for a specific event or simply working out to stay healthy, it’s important to view yourself as an athlete. Treating your body with the respect and care it deserves means optimizing the controllables: nutrition, training, sleep, recovery, stress management, and hydration. These foundations will always give you the most significant return on investment for your health and performance.
Supplements are just that—a supplement to an already optimized lifestyle. A food-first approach should always be the priority. Focus on obtaining as many nutrients as possible through a balanced, nutrient-dense diet. However, for many active adults and athletes, supplementation can help fill gaps and support performance and recovery. Before starting any new supplement, always consult a healthcare professional to ensure it aligns with your individual needs and health conditions.
Here are six evidence-based supplements every active individual should consider:
1. Protein
What it does: Protein is essential for muscle repair and growth. It supports recovery after workouts and helps maintain lean muscle mass, especially during periods of caloric deficit or intense training.
Why it’s important for athletes: Athletes have higher protein needs than sedentary individuals to repair the muscle damage caused by exercise and support adaptation to training.
How to take it:
- Dose: Aim for 20-40 grams of protein per serving, depending on your total daily protein needs.
- Timing: Consume within 1-2 hours post-workout for optimal recovery. Protein can also be spread evenly across meals and snacks throughout the day.
- With food or alone: Can be taken with or without food, often combined with carbohydrates post-exercise for better recovery.
2. Creatine Monohydrate
What it does: Creatine enhances the production of adenosine triphosphate (ATP), the primary energy source for high-intensity activities like lifting and sprinting. It also supports muscle hydration and strength gains.
Why it’s important for athletes: Creatine improves strength, power, and recovery, making it a cornerstone for both recreational and competitive athletes.
How to take it:
- Dose: 3-5 grams daily. A loading phase of 20 grams/day (split into four doses) for 5-7 days can saturate muscle stores faster but isn’t necessary.
- Timing: Any time of day, ideally with a meal containing carbohydrates for better absorption.
- With food or alone: Best taken with food to enhance absorption.
3. Vitamin D
What it does: Vitamin D supports bone health, immune function, and muscle strength. Many people, especially those in colder climates or who spend a lot of time indoors, are deficient.
Why it’s important for athletes: Adequate vitamin D levels reduce the risk of stress fractures, improve muscle function, and support overall recovery.
How to take it:
- Dose: 1,000-4,000 IU daily, depending on your current levels (a blood test can help determine this).
- Timing: Morning or with your largest meal of the day.
- With food or alone: Take with food containing fat for better absorption.
4. Magnesium
What it does: Magnesium is involved in over 300 enzymatic reactions in the body, including muscle function, energy production, and stress regulation.
Why it’s important for athletes: Intense training can deplete magnesium stores, leading to muscle cramps, poor recovery, and sleep disturbances.
How to take it:
- Dose: 300-400 mg daily, depending on dietary intake.
- Magnesium glycinate for sleep
- Magnesium malate for muscles and energy
- Magnesium threonate for cognition and memory
- Timing: Evening, as it can promote relaxation and better sleep.
- With food or alone: Take with food to reduce stomach upset.
5. Collagen
What it does: Collagen supports joint, tendon, and ligament health, as well as skin elasticity. When combined with vitamin C, it helps stimulate collagen production in the body.
Why it’s important for athletes: Active individuals place high demands on their joints and connective tissues, making collagen supplementation beneficial for injury prevention and recovery.
How to take it:
- Dose: 10-15 grams daily.
- Timing: 30-60 minutes before exercise when combined with 50-100 mg of vitamin C.
- With food or alone: Can be taken with or without food.
6. Omega-3 Fatty Acids
What it does: Omega-3s reduce inflammation, support cardiovascular health, and improve joint and brain health.
Why it’s important for athletes: Omega-3s aid in recovery by reducing exercise-induced muscle soreness and inflammation.
How to take it:
- Dose: 1-3 grams of combined EPA and DHA daily.
- Timing: Any time of day.
- With food or alone: Take with a meal containing fat for better absorption.
Evidence-Based Supplements for Every Athlete
While supplements can provide a valuable boost, they should never replace the foundations of good health: a well-rounded diet, consistent training, adequate sleep, and stress management. By focusing on these fundamentals and incorporating evidence-based supplements where needed, you can support your body and reach your goals effectively.
As always, consult with a medical professional or sports pharmacist before adding any supplements to your routine. Your body is your greatest tool—fuel it wisely and treat it like the athlete’s body it is.
