Best Supplements for Runners + What They Actually Do

When I was younger, I could run for miles every day with zero issues. In fact, ran several half-marathons fueled only by tiny cups of Gatorade and GU gel packs, and recovered within the same day.

But when I tried to get back into running nearly a decade later, I found my body just couldn’t function as well without the proper nutrition and supplementation to back it up. And after years of trial and error, I’ve finally found the perfect blend of supplements to fuel my runs without going broke.

So…what are the best supplements for runners? I’m so glad you asked!

Fundamentals of Nutrition for Runners

As endurance athletes, our nutrition is crucial to our performance and recovery. It’s not just about eating healthy; it’s about carefully choosing the right balance of nutrients that fuel your runs and aid your body’s repair process.

Importance of a Balanced Diet

A balanced diet is the cornerstone of any running regimen. Your body requires a diverse mix of nutrients to function optimally, especially as you age!

Healthy diet choices that include a variety of food sources can ensure you get the full spectrum of essential nutrients for both energy production and recovery. Carbohydrates, fats, and proteins are the macro triumvirate that power your muscles, while vitamins and minerals play vital supporting roles.

Macro and Micronutrient Overview

  • Carbohydrates: Your primary energy source, carbohydrates should be the bulk of your intake. Whole grains, fruits, and vegetables are optimal food sources.
  • Proteins: Essential for muscle repair, aim to include protein in every meal, with a focus on lean meats, dairy, or plant-based alternatives like legumes and tofu.
  • Fats: Healthy fats are crucial for long-lasting energy. Incorporate sources like nuts, seeds, and avocados.
  • Vitamins and Minerals: These micronutrients support a range of bodily functions from bone health to immune response. A diet rich in fruits, vegetables, nuts, seeds, dairy, and lean meats can cover your needs.

Best Supplements for Runners: Key Vitamins

In your quest for better athletic performance, key vitamins play a crucial role in boosting energy, aiding recovery, and protecting your body. 

Roles of B Vitamins in Energy and Recovery

B vitamins are a group of nutrients that work closely with your body’s energy production processes. As a runner, your body demands high levels of energy, which is where vitamin B really shines. 

Each of the B vitamins – from B1 (thiamine) to B12 (cobalamin) – contributes to the efficient conversion of dietary energy into ATP (adenosine triphosphate), the fuel your muscles burn during a long run. Additionally, some B vitamins like B6 and B12 play a pivotal role in the formation of red blood cells and repair of tissues, helping you recover after strenuous workouts. 

And it’s not just stamina for long-distance runners that these vitamins boost! They’re also involved in preventing stress fractures, essential for runners looking to stay healthy and injury-free.

  • Thiamine (B1): Assists in converting carbs into energy.
  • Riboflavin (B2): Crucial for breaking down fats and proteins.
  • Niacin (B3): Supports metabolic function during running.
  • Pyridoxine (B6): Necessary for protein metabolism and red blood cell production.
  • Cobalamin (B12): Aids in the production of red blood cells and prevention of anemia.

Divine Bounty offers a high-potency vitamin B complex that won’t break the bank.

Antioxidant Benefits of Vitamin C

Vitamin C isn’t just for fighting colds; it’s a powerful antioxidant that combats the oxidative stress caused by intense physical activity, especially that of long-distance runners and other endurance athletes. 

As you run, your body is swamped with free radicals, which can lead to muscle fatigue and hinder recovery. Vitamin C helps neutralize these harmful molecules, promoting quicker recovery and reducing the risk of inflammation

This essential vitamin, when taken consistently, may bolster your immune system, making you less susceptible to exercise-induced immunosuppression. Additionally, by contributing to collagen production, vitamin C is vital for maintaining the health of your bones and tissues, thereby supporting strong joints and potentially averting stress fractures. 

  • For Immune System: Supports the defense mechanism of the body against pathogens.
  • For Recovery: Aids in the repair of tissues and eases muscle soreness.
  • For Bone Health: Contributes to the synthesis of collagen, necessary for strong bones.

I enjoy gummy supplements because I’m a child, haha, and so take Vitafusion’s Power C.

Best Supplements for Runners: Essential Minerals

Minerals also play a pivotal role in your running performance and recovery. They’re not just part of a healthy diet—they’re direct contributors to your endurance and muscle function.

Iron’s Crucial Role in Athletic Endurance

Iron is a key component of hemoglobin, the protein in your red blood cells that carries oxygen in your blood flow to your muscles. 

When you have low iron levels, your oxygen-carrying capacity diminishes, which can leave you feeling fatigued and impact your endurance. That’s why it’s crucial to maintain healthy iron levels, especially for long-distance runners.

If you suspect you might have low iron, a blood test is the most reliable way to check. Depending on the results, incorporating an iron supplement like MegaFood Blood Builder Minis into your diet might be beneficial.

Electrolyte Balance and Muscle Contraction

Electrolytes, including minerals like sodium, potassium, calcium, and magnesium, are vital for muscle contraction and maintaining fluid balance in your body. 

As you run, you lose electrolytes through sweat, and this loss can lead to muscle cramps and weakness. To help prevent this, ensure you’re consuming electrolytes through your diet or supplements like Liquid IV

Remember, a careful balance is key—you want to replenish what you’ve lost without overdoing it. To maintain proper electrolyte balance, hydrate with electrolyte-rich drinks during long runs or intense workouts.

Best Supplements for Runners: Protein and Amino Acids

Incorporating the right balance of proteins and essential amino acids into your diet can significantly enhance your muscle tissue repair and recovery processes. Think of them as the building blocks that help you bounce back better after a run.

Benefits of Whey Protein for Muscle Tissue

Whey protein is renowned for its rich amino acid profile and fast absorption, making it an excellent choice for supporting protein synthesis in your muscles. 

  • Fast Absorbing: Whey is quickly taken up by your body, providing rapid nutrients to the muscles.
  • Rich in BCAAs: It’s loaded with branched-chain amino acids (BCAAs), particularly leucine, which plays a pivotal role in muscle building.

Essential Amino Acids for Recovery

Your body requires twenty different amino acids, nine of which are considered essential because your body does not produce them naturally. These essential amino acids must come from your diet and are vital for muscle recovery and repair.

  • Leucine, Isoleucine, and Valine: Among these essential amino acids, leucine, isoleucine, and valine are particularly beneficial for muscle recovery.
  • Histidine and Methionine: Histidine, in combination with methionine, is used by your body to create histamine, which is essential for immune response, digestion, sexual function, and sleep-wake cycles.

Including a supplement that provides all nine essential amino acids can support comprehensive muscle recovery and overall health. For more information on essential amino acids and muscle health, you might find this article on the best amino acids for muscles helpful.

Best Supplements for Runners: Fats and Fatty Acids

When it comes to your athletic performance and overall health, incorporating the right kinds of fats, particularly omega-3 fatty acids, is crucial. You’ll find that these specific fatty acids, often found in fish oil supplements, play a vital role in maintaining joint health and managing inflammation.

Omega-3s and Joint Health

Omega-3 fatty acids are essential for runners because they contribute to maintaining healthy joints. Since running can put a lot of strain on your joints, incorporating omega-3s into your diet can help cushion and protect them. 

You can enhance your joint health by including a fish oil supplement that’s rich in omega-3s, which are not naturally produced by your body and must be obtained through diet or supplementation. I pick up a specialized fish oil supplement from my doctor, but used to enjoy NOW Omega-3 Softgels before I switched.

Managing Inflammation with Fish Oil

But that’s not all fish oil can do! It’s also well-known for its anti-inflammatory properties. And as a runner, managing inflammation is key to recovery and sports performance. 

Inflammation can lead to muscle soreness and delay recovery, but by taking fish oil supplements, you can help reduce this inflammation, making your post-run recovery faster and more effective. Being proactive with your inflammation management can pave the way for more consistent, pain-free runs.

Energy Gels and Long Runs

Energy gels can be crucial for maintaining high enough energy levels for a long run.

They’re designed to be easily digestible and to provide a quick source of carbohydrates. These are your muscles’ preferred source of fuel during extended periods of exercise. 

A typical energy gel contains a blend of simple sugars that your body can absorb rapidly, and caffeine, which may offer an additional energy boost. I’ve tried lots of energy gels over the years, but keep coming back to GU for it’s efficiency and taste.

  • Usage Tip: Consume an energy gel every 45-60 minutes during long runs to sustain endurance and delay muscle fatigue.

Preventing Muscle Cramps and Fatigue

Muscle cramps can be a runner’s arch nemesis, often stemming from electrolyte imbalances or dehydration. Electrolyte supplements, whether those in pill or powder form, can help maintain the balance of fluids in your body and reduce the risk of cramps.

  • Electrolyte Balance: Ensure your supplement contains a balanced mix of electrolytes.
  • Hydration: Pair your electrolytes with adequate water intake.

Additionally, vitamin D and magnesium supplements may aid in muscle recovery and function, thus potentially reducing fatigue and muscle cramps post-run. 

Remember to always tailor your supplement regimen to fit your body’s reactions and the demands of your running program. Hydrate consistently and listen to your body’s signals to adjust your supplement intake as needed.

Understanding and Avoiding Common Deficiencies

When you’re hitting the pavement or the trails, your nutrition is just as crucial as your training plan. To maintain your overall health and avoid hitting a wall, being aware of common deficiencies is key.

Iron is pivotal for runners, as low iron levels can lead to fatigue and impede performance. Ensure you’re consuming iron-rich foods like leafy greens and lean meats, or consider a supplement—especially if you’re a female or vegetarian runner due to higher risk of deficiency.

NutrientFood SourcesSupplement Consideration
IronSpinach, Red MeatIf dietary sources are insufficient
Vitamin DSunlight, EggsIn winter months or low sun exposure
CalciumDairy, BroccoliFor bone health, if dairy intolerant

Your body works hard for you, so give it the nutrients it craves. A well-rounded diet with a variety of unprocessed foods generally supplies what you need, but supplements can fill in the gaps. 

BCAAs, or branched-chain amino acids, support muscle recovery post-run. Meanwhile, for general wellness, multivitamins can act as a nutritional safety net.

Remember, hydration is not to be overlooked.

Electrolyte imbalances can bring on fatigue as quickly as any vitamin deficiency. Your fluid intake is as crucial as your solid food diet.

Before starting any supplement, it’s always wise to consult with a healthcare professional. This step ensures what you’re taking complements your unique health profile and goals. That’s how I personally learned that my body chemistry wasn’t allowing me to absorb the fish oil supplement I was taking, and to know which supplement would absorb well!

How to Choose the Right Supplements

When selecting supplements, your main focus should be on understanding what’s in them and ensuring they meet high-quality standards. Taking the right supplements can complement your diet and offer health benefits, but it’s essential to choose wisely.

Deciphering Supplement Labels

To make an informed decision, start by reading the label carefully. 

Look for supplements that have a clear indication of what’s inside, including the amount of each nutrient. For instance, you should be able to find the dosage of vitamin per serving. 

It may also be beneficial to conduct a blood test to identify any specific nutrient deficiencies that your diet may not cover. This can then guide your choice of dietary supplements.

Quality and Testing of Supplements

The quality of a supplement is determined by its manufacturing processes and whether it has been tested for purity and potency. Opt for products from companies that follow Good Manufacturing Practices (GMP) and are tested by third parties. 

Always opt for brands that maintain transparency and provide proof of their product’s quality and safety.
