Supplements That Have Science on Their Side

Not all supplements are created equal. Below are some that have solid research behind them, along with what they actually do.

1. Creatine: The MVP of Performance

Creatine monohydrate is one of the most well-studied supplements for athletes. It helps your muscles produce more energy, which can improve strength, power, and endurance. Plus, new research suggests creatine may also support brain function and bone health—especially in women. A daily dose of 5 grams is enough to see benefits.

💡 Best for: Strength training, high-intensity workouts, and muscle recovery.

2. Beta-Alanine: Fighting Fatigue

Ever feel that burning sensation in your muscles when pushing through a tough workout? Beta-alanine helps delay that fatigue by buffering acid buildup in your muscles. It’s especially helpful for activities that require bursts of effort, like sprinting or weightlifting. The typical dose is around 65 mg per kg of body weight, spread throughout the day.

💡 Best for: High-intensity workouts and endurance training.

3. Omega-3s: The Recovery Booster

You probably know omega-3s are great for heart health, but did you know they can also reduce inflammation and muscle soreness? Found in fish oil, these fatty acids help protect the brain and may even improve recovery after tough workouts. Many athletes benefit from doses up to 5 grams per day.

💡 Best for: Reducing soreness, improving recovery, and brain health.

4. Magnesium: The Underrated Essential

Magnesium plays a huge role in muscle function, sleep, and stress management. However, up to 90% of athletes may be deficient! While there are many forms of magnesium, magnesium citrate is more easily absorbed than magnesium oxide.

💡 Best for: Muscle function, recovery, and better sleep.

5. Vitamin D: The Sunshine Nutrient

Low vitamin D levels can lead to fatigue, weakened immunity, and poor bone health. Many people (especially those who train indoors) don’t get enough. While individual needs vary, some athletes require up to 10,000 IU daily to correct deficiencies—but always check your blood levels before supplementing!

💡 Best for: Bone health, immune function, and overall well-being.

6. Iron: Essential for Energy

If you feel tired all the time—especially if you’re an active woman—low iron levels could be the culprit. Iron is crucial for oxygen transport and energy production. Since too much iron can be harmful, it’s best to get your levels checked before supplementing.

💡 Best for: Endurance athletes, women, and those with low energy.

7. Beetroot Juice: A Natural Performance Enhancer

Beetroot juice is packed with nitrates that can improve blood flow and oxygen delivery to muscles, boosting endurance. To maximize benefits, drink it 2–3 hours before training.

💡 Best for: Endurance sports and cardiovascular performance.

Final Thoughts: Do You Need Supplements?

Supplements can be helpful, but they should never replace a well-balanced diet. Before spending money, ask yourself:

✅ Am I already getting enough from food?

✅ Do I actually need this based on my goals and lifestyle?

✅ Is there solid research supporting its benefits?

By focusing on the essentials and skipping the gimmicks, you’ll make smarter choices for your health and performance. Want personalized supplement advice? Always check in with a registered dietitian or healthcare provider!
