5 Sports Nutrition Questions Every Endurance Athlete Asks

By Matt Johnson

Founder of The Feed.

I get the same five questions over and over from athletes. So, I figured, let’s tackle them all at once. Here’s what everyone wants to know.

“Matt, what’s the one thing that’ll actually make me faster?”

Look, there is a clear winner here. If you want to push past that wall where your legs are screaming and your lungs are on fire, try Maurten Bicarb.

I know, I know - it’s just expensive baking soda. But without the Maurten formula, you are way more likely to end up in the bushes versus the finish line. Maurten finally cracked the code with their hydrogel tech that shields your stomach from the sodium bicarbonate.

The science is legit - it buffers the acid buildup in your muscles, allowing you to hold that painful pace longer. Every pro I talked to at the Tour de France was using it. David Roche won Leadville with it. Hunter McIntyre used it at the HYROX World Champs to go unbroken on wall balls for the first time, ever.

Just test it in training first. Trust me on this one. Each box contains 4 servings calculated by body weight, so that you can dial it in before race day.

It's not just for races. You can use it for your one really hard workout that week and get more gains from the harder effort you can put out (and crush your training partners), enabling you to break through training plateaus. I’ve heard many of the World Tour Cycling Pros are doing this in training at least once a week.

My P.S. on this one is that you should also be using the new SwissRX Nitric Oxide Pro (two capsules daily). It is your first line of performance gains as it increases blood flow, so you can go harder for longer before the acid builds up, then when you do anaerobic, the bicarb kicks in to neutralize the change in pH levels.

“What supplement do you actually take every single day?”

SwissRX Synthesis. No question.

This stuff completely changed my training at 50. I went from being stuck at the same weights for years to suddenly breaking through every plateau. My running intervals dropped from 7:30 pace to low 6-minute miles. (And I'm hardly built like a runner.)

The secret is PeptiStrong® – a peptide from fava beans that makes your body build muscle 4x faster than whey protein alone. I stopped taking it for a month as a test, and my training and recovery returned to normal (cutting workouts short and skipping days after a hard day). Started again and boom – back to making gains and consistent training.

"What’s the best value in hydration?”

Two answers depending on what you’re doing:

For everyday hydration when I’m just sitting at my desk or walking around – Enervit Electrolytes Boost. 400 mg sodium, 56mg magnesium, only 2 calories. No sugar. It’s what I drink all day.

For training and rehydration after workouts - The Feed Lab Hydration. We made this because I was tired of paying $2+ per serving; it’s only $0.83 per serving! It’s got everything you need (450 mg sodium plus the other electrolytes), tastes good enough that you’ll actually drink it, and won’t destroy your wallet when you’re training every day. Plus, no Stevia, it contains real cane sugar, but just 8 g of carbs.

“How do I save money on fueling?”

This year, the theme has been how to save money on fueling. I get it and feel the same. I never predicted tariffs or the economic changes, but we saw this coming and over a year ago said it is crazy to ask someone to spend $30 to fuel a two-hour workout. This is why the team and I developed The Feed Lab.

I mentioned the new Hydration above, but other Feed Lab products are science-backed, best-in-class formulas with huge savings:

  • The Feed Lab Creatine (only $25 for 60 Servings!)

  • The Feed Lab High Carb Drink (only $0.66 per bottle, and you can mix 30 g, 60 g or 90 g of carbs)

  • The Feed Lab Whey Protein (delicious and the best protein deal we have)

“What’s your #1 recovery hack?”

SLEEP. Everything else is noise if you’re not sleeping.

I take Pillar Triple Magnesium almost every night – three different forms of magnesium that actually get absorbed. But the real game-changer for my sleep? Dream Shot.

I used to wake up at 2 am, stare at the ceiling, and stress about tomorrow’s workout being ruined, which would spike my cortisol levels, making it even harder to fall back asleep – brutal cycle.

Dream Shot fixed it. One 2-ounce shot has everything: real tart cherry juice (not powder), Magtein magnesium that crosses the blood-brain barrier, 3 g of glycine to drop your body temp, L-theanine to shut up that voice in your head, ashwagandha for stress, and PeptiSleep™ to stop those middle-of-the-night cortisol spikes that used to wake me up. My sleep scores went from 60s-70s to breaking into the 90s. REM and deep sleep up 20-60%.
