• Who might benefit most: Vegan and vegetarian runners may have a higher risk of B12 deficiency, making supplementation crucial.

6. Vitamin D3 with K2

Vitamin D3 is essential for bone health, immune function, and muscle performance. It helps the body absorb calcium, reducing the potential risk of stress fractures. When paired with vitamin K2, the benefits are amplified. Vitamin K2 ensures that calcium is properly directed to your bones and teeth, rather than accumulating in arteries or soft tissues.

• Why runners need it: Runners may be at risk of vitamin D deficiency, especially those training indoors or during colder months. Adding K2 can help maximize bone strength and reduces the risk of calcium-related complications. Together, they support better recovery and stronger performance. The D3-K2 combination also supports cardiovascular health by preventing calcification of arteries.

7. Zinc

Zinc plays a crucial role in immune function, protein synthesis, and muscle repair. It also helps the body recover from oxidative stress. Exercise can impact zinc levels in the body, potentially leading to mild deficiencies in athletes that may affect recovery, health, and performance, highlighting the importance of maintaining adequate zinc intake for active individuals.

• Why runners need it: Running increases oxidative stress and can weaken the immune system. Zinc supplementation supports recovery and keeps you healthy during intense training cycles.

8. Omega-3 Fatty Acids

Omega-3 fatty acids, commonly found in fish oil, are renowned for their anti-inflammatory properties and cardiovascular benefits. These essential fats, particularly EPA and DHA, also support joint health and enhance endurance by improving oxygen delivery during exercise.

• Why runners need it: Regular running can cause inflammation and oxidative stress, which can hinder recovery. Omega-3s help reduce muscle soreness, protect joints, and promote better overall performance. Studies show omega-3s can enhance recovery speed and even boost mental clarity, which is helpful for long runs and race preparation.

9. Protein Powder

Protein is vital for muscle repair and recovery. While whole foods are the best source, protein powders offer a convenient sports nutrition option for post-run recovery. A study of recreational master runners found that higher protein intake during marathon training and the race itself was strongly linked to better body composition preservation and reduced muscle damage. Runners who consumed more protein experienced fewer changes in body fat, lean mass, and metabolic stress markers, highlighting the importance of protein for endurance performance and recovery.

• Why runners need it: High-quality protein powders with a complete amino acid profile, such as whey, replenish muscles after long runs, supporting faster recovery.
• Tip: Look for powders with minimal sugar and added ingredients.

How to Choose the Right Supplements for Your Training Goals

Other Tips for Maximizing Performance and Recovery for Runners

In addition to taking the right supplements, runners can optimize their performance and recovery by focusing on other key areas of their training and lifestyle. Here are some additional tips:

1. Prioritize Carbohydrates for Energy

Carbohydrates are essential for runners as they provide the primary fuel for endurance activities. Consuming adequate carbs before a run helps build muscle glycogen stores, while post-run carbs replenish depleted energy and kickstart recovery.

• Pre-run: Focus on easily digestible carbs like bananas, oatmeal, or a slice of toast with honey 30–60 minutes before running.
• During long runs: Carbohydrate gels, chews, or drinks can sustain energy for runs lasting over an hour.
• Post-run: Combine carbs with protein in a 3:1 ratio for faster glycogen replenishment and muscle repair. A smoothie with protein powder, banana, and a touch of honey is a great option.

2. Stay Hydrated

Proper hydration is critical for performance and recovery, especially for endurance athletes. Losing just 2% of your body weight in fluids can significantly impact endurance and energy levels.

• During runs: Use a combination of water and electrolyte-rich beverages to replace lost fluids and minerals.
• After runs: Drink enough fluids to fully rehydrate and restore electrolyte balance.

3. Focus on Recovery Nutrition

Recovery meals should include a mix of protein, carbs, and healthy fats. Protein supports muscle repair, carbs replenish glycogen, and fats help reduce inflammation. Don’t forget to include nutrient-dense foods like leafy greens, nuts, and seeds for added vitamins and minerals.

Incorporate iron-rich food sources, such as lean red meat, spinach, lentils, or fortified cereals, into your recovery meals. Iron is essential for replenishing oxygen-carrying red blood cells, which can become depleted with intense training. Pair plant-based iron sources with vitamin C-rich foods (like bell peppers or citrus) to boost absorption. While some may opt for an iron supplement, it's important to be cautious of high intakes of iron due to toxicity risk. 

4. Get Enough Sleep

Sleep is when your body repairs itself. Aim for 7–9 hours of quality sleep per night to enhance recovery, support muscle repair, and maintain energy levels. 

5. Warm Up and Cool Down

Dynamic stretches before a run and static stretches afterward help improve flexibility, prevent injuries, and reduce soreness. A good warm-up increases blood flow and primes your muscles for exercise, while a proper cool-down helps your body return to its resting state.

6. Plan Rest Days

Rest days are just as important as training days. They allow your body to repair and rebuild, preventing overtraining and reducing the risk of injuries. Active recovery, like light yoga or walking, can help maintain movement while giving your muscles a break.
