Beyond Electrolytes and BCAAs: Advanced Supplementation for Endurance Athletes

Hey Angels and Alphas,

Endurance athletes push their bodies to the limits, requiring optimal nutrition and supplementation to support performance, recovery, and overall health.

While electrolytes and branched-chain amino acids (BCAAs) are commonly associated with endurance sports, advanced supplementation protocols can offer additional benefits to athletes striving for peak performance.

In this short guide, we will explore advanced supplementation strategies that go beyond electrolytes and BCAAs, focusing on key nutrients, supplements, and protocols that can enhance endurance, reduce fatigue, and support the demands of endurance training.


Beta-alanine is an amino acid that helps increase muscle carnosine levels, which buffers acidity and delays muscle fatigue during intense exercise. Supplementing with beta-alanine has been shown to improve endurance performance and delay fatigue, particularly in high-intensity, short-duration activities. To maximize its benefits, athletes can take beta-alanine in divided doses throughout the day to maintain elevated carnosine levels.

Citrulline Malate

Citrulline malate is a compound that boosts nitric oxide production, leading to increased blood flow, improved oxygen delivery, and enhanced muscle endurance. It also aids in reducing muscle soreness and fatigue. Endurance athletes can benefit from supplementing with citrulline malate before training or competition to enhance performance and promote faster recovery.

Nitrate-Rich Foods and Beetroot Juice

Dietary nitrates found in foods like beetroot, spinach, and arugula can enhance endurance performance by improving blood flow, reducing oxygen cost, and increasing exercise efficiency. Consuming nitrate-rich foods or beetroot juice before training or competition can help enhance endurance and delay the onset of fatigue.


Carnitine plays a crucial role in energy metabolism by facilitating the transport of fatty acids into the mitochondria, where they are oxidized for fuel. Supplementing with carnitine can enhance endurance performance by improving fat utilization, sparing muscle glycogen, and delaying fatigue. Acetyl-L-carnitine and L-carnitine L-tartrate are the most common forms used in supplementation.

Omega-3 Fatty Acids

Omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have anti-inflammatory properties and support cardiovascular health. Endurance athletes can benefit from incorporating omega-3 fatty acids into their supplementation routine to reduce exercise-induced inflammation, promote recovery, and support overall well-being. Fish oil or algae-based omega-3 supplements are excellent sources of EPA and DHA.


Adaptogens are natural substances that help the body adapt to physical and mental stress. Popular adaptogenic herbs like rhodiola rosea, ashwagandha, and ginseng can improve endurance capacity, reduce fatigue, and enhance mental focus and resilience. Including adaptogens in a supplementation protocol can help athletes manage the physical and psychological demands of endurance training.

Tart Cherry Juice

Tart cherry juice is rich in antioxidants and has been shown to reduce inflammation, muscle damage, and oxidative stress associated with intense exercise. Consuming tart cherry juice before and after endurance training or competition can aid in recovery, improve sleep quality, and mitigate post-exercise muscle soreness.


Magnesium is a vital mineral involved in energy production, muscle function, and electrolyte balance. Endurance athletes are at an increased risk of magnesium deficiency due to high sweat losses and increased energy demands. Supplementing with magnesium can support muscle relaxation, reduce cramping, and optimize energy metabolism. Magnesium citrate or magnesium glycinate are recommended for better absorption.

Vitamin D

Vitamin D deficiency is prevalent among athletes (and, to be fair, a lot of people) and can negatively impact performance and recovery. Adequate vitamin D levels are essential for optimal bone health, immune function, and muscle strength. Athletes should consider regular sun exposure or vitamin D supplementation, especially during the winter months or when training predominantly indoors.


Advanced supplementation protocols offer endurance athletes additional tools to support performance, enhance recovery, and optimize overall health.

Beyond electrolytes and BCAAs, incorporating beta-alanine, citrulline malate, nitrate-rich foods, carnitine, omega-3 fatty acids, adaptogens, tart cherry juice, magnesium, vitamin D, and personalized sports nutrition support can help athletes reach new levels of endurance, reduce fatigue, and promote long-term well-being.

It is important for athletes to consult with healthcare professionals or qualified sports nutritionists to design individualized supplementation plans that align with their specific needs and training goals.

Remember, supplementation should always complement a balanced diet and a comprehensive training program to maximize performance and achieve optimal results.
