Where to Start with Vitamins & Supplements as an Endurance Athlete

Supplements as the Finishing Touch

Supplements are exactly that—a supplement to a healthy, well-rounded lifestyle. For endurance athletes, peak performance doesn’t start with pills or powders. It starts with the fundamentals: quality sleep, balanced nutrition and hydration, smart training with rest days, and a supportive community.

Yet even when all of that is dialed in, endurance training and racing place unique demands on your body, often exceeding what diet alone can provide. Long hours, heat, travel, and cumulative training stress can deplete micronutrients and challenge recovery.

This is where the right vitamins and supplements can make a meaningful difference—filling critical gaps, enhancing recovery, and helping you feel and perform at your best, day after day. And from our side at Wahoo, we partner with Momentous because their rigor, transparency, and athlete-first formulations align with how we think about performance: do the fundamentals right, then use science-backed tools to go the extra mile.

So, where should you start? Let’s break down a supplement strategy designed specifically for endurance athletes.

1. Foundational Products: Your Daily Stack

Think of your foundational supplements as the nutritional equivalent of base miles—steady, consistent, and essential for long-term performance.

The Momentous ThreeTM: Protein. Creatine. Omega-3. Taken daily, this essential trio delivers powerful, compounding benefits for the muscular, cardiovascular, and cognitive systems to help fuel a lifetime of high performance. Because it’s tough to get optimal amounts from diet alone, The Momentous Three™ is designed to fit seamlessly into any routine—with no cross-reactivity, fully vegan options, and formulas ideal for every body, every day. If 80% of your results come from 20% of your effort, consider The Momentous Three™ your 20%.

Momentous Multivitamin: Fills the micronutrient gaps common in athletes with high training loads or busy lives. 

Momentous Vitamin D3 5000 IU: Supports immune function, bone health, and energy metabolism—all critical for year-round training. Also available as 2000 IU

Momentous Iron+: Supports oxygen transport and energy production. Our Iron+ is sourced from Ferrochel® iron for maximum bioavailability and minimal GI distress with added Vitamin C to further aid absorption and Vitamin B Complex to support energy production.

The Women’s Three: Developed in partnership with Dr. Stacy Sims, The Women’s Three combines Iron+, Calcium, and Vitamin D for hormonal balance, bone health, and longevity for women across all phases of life. 

2. Sleep: The Ultimate Recovery Tool

Training only works if you can adapt and recover—and that happens when you sleep. Deep, restorative sleep is the ultimate performance enhancer.

Momentous Nightly Sleep: Supports natural relaxation and sleep onset with Magnesium L-threonate, Apigenin, and L-Theanine. Ideal for athletes who struggle to switch off or want to optimize nightly recovery. Contains zero melatonin, non-habit forming, and safe for daily use.  

Momentous Elite Sleep: Perfect for travel, race weeks, or high-stress training blocks, providing a one-off reset when your schedule or time-zone changes disrupt sleep quality and you need to get back on track.

3. For Training: Energy and Endurance Support

Fueling properly before, during, and after training ensures your body has what it needs to perform, adapt, and recover.

Momentous Fuel: Delivers clean, easily digestible carbohydrates and electrolytes for sustained energy through long or intense sessions—without GI distress.

Momentous Whey or Plant Protein: Fast-absorbing protein to support lean muscle and recovery, and help you hit your optimal daily protein intake.

Momentous Recovery: Designed to help rebuild muscle and restore glycogen after every session with premium protein, carbs, amino acids, and electrolytes.

Momentous Vital Aminos: A precise blend of essential amino acids that support endurance performance, muscle preservation, and reduced fatigue during long efforts.

4. For Recovery: Repair & Rebuild

Recovery is where fitness gains are made and where consistency is earned. The right nutrients can help your body repair faster and bounce back stronger.

Collagen Peptides: Supports joint, tendon, and ligament health—crucial for high-mileage athletes and anyone managing repetitive stress.

Magnesium Malate: Highly bioavailable magnesium that promotes muscle relaxation, electrolyte balance, and soreness reduction.

Turmeric: A natural anti-inflammatory that helps manage post-training soreness and muscle breakdown. 

L-Glutamine: Aids gut integrity and immune resilience, especially during heavy training or travel.

5. Designed for Real Life: Vegan-Friendly & Travel-Ready
