I was scrolling through my feed last week when I saw something that made me do a double-take. Katya Gorbacheva, a powerlifter who deadlifts 182.5 kg (that’s 400+ pounds), was talking about her protein sources. No whey powder. No chicken breast. Just plants.
But here’s the kicker—she wasn’t just living on tofu either.
The reality? Elite athletes are quietly revolutionizing their protein game with sources most of us walk right past at the store. We’re talking Olympic athletes, ultra-runners, and professional fighters who’ve discovered that some of the most powerful proteins on the planet have been hiding in plain sight.
These six proteins are fueling athletes at the highest levels—and they’re probably already at your local store. You just didn’t know what you were looking at.
Let’s get into it.
1. Hemp seeds: Complete protein with built-in recovery
The tiny seeds that pack a massive punch. We’re talking about a complete protein—all nine essential amino acids—with a bonus round of omega-3s that fight inflammation like a natural ice bath.
The numbers: Three tablespoons = 10g complete protein + omega-3 fatty acids
I first discovered hemp seeds at a health food store in Portland (of course). The shop owner, an ultra-marathoner, told me he adds them to everything—smoothies, oatmeal, even his post-run pasta. “It’s like upgrading your recovery protocol without changing anything else,” he said.
Science backs this up—hemp seed protein showed protective effects against muscle breakdown and improved recovery markers. Plus, hemp seeds are loaded with arginine (for better blood flow) and GLA—both linked to reduced inflammation.
Translation? Less soreness, faster recovery between sessions.
How to use: Add 2-3 tablespoons to post-workout meals. Don’t cook them—heat damages the omega-3s.The taste is mild and nutty, nothing like what you might expect from the cannabis family.
2. Tempeh: Fermented soy that speeds muscle repair
Forget everything you think you know about soy. Tempeh is fermented soybeans bound together in a firm, nutty cake—and it’s changing how athletes approach recovery. Unlike tofu’s sometimes mushy texture, tempeh has a satisfying bite and earthy flavor that even meat-eaters appreciate.
The numbers: 100g serving = 19g protein + probiotics
Indonesian athletes have been using this for centuries. Now Western sports scientists are catching up. Research shows that tempeh’s fermented probiotics help reduce exercise-induced muscle damage and speed recovery.
The fermentation process is key—it breaks down proteins, making them easier to absorb. Plus, you get the gut health benefits of probiotics, which correlates to improved athletic performance and immune function.
How to use: Pan-fry with tamari and ginger. Start with 100g servings to assess digestive tolerance.
3. Spirulina: Concentrated protein with antioxidant powers
This blue-green algae packs 60-70% protein by weight. To put that in perspective, beef contains about 26% protein, and even chicken breast tops out around 31%. We’re talking about one of the most concentrated protein sources on the planet.
The numbers: 1 teaspoon = 2g protein + C-phycocyanin (potent antioxidant)
Aztec warriors used to harvest it from lakes and eat it before battle. Modern elite rugby players are doing basically the same thing—studies revealed spirulina supplementation prevented exercise-induced damage and helped maintain training intensity.
Double Olympic gold medalist Lee Evans shared his experience: “Spirulina improved my performance, gave me speed and increased my endurance.”
How to use: Start with 1 teaspoon in strongly flavored smoothies. The taste is intense—like concentrated seaweed. Mix it with berries and citrus to mask the ocean flavor.
4. Amaranth: The endurance grain
Ancient grain, modern performance enhancer. This one’s been flying under the radar while quinoa gets all the press.
The numbers: 1 cup cooked = 9g complete protein + iron + magnesium
Here’s why athletes should care: research found that amaranth naturally boosts nitric oxide production through its nitrate content. That means better blood flow, improved oxygen delivery to muscles, and enhanced aerobic capacity. One pilot study with trained cyclists found those drinking an amaranth-based beverage completed their time trials faster than those using a commercial sports drink.
This performance boost isn’t surprising when you consider that the Tarahumara runners of Mexico—famous for their ultra-distance running abilities—have been eating amaranth for generations. Christopher McDougall documented this in “Born to Run,” observing that they called it their “running food” and consumed it before their legendary long-distance runs.
Unlike other grains, amaranth maintains its nutritional integrity even when popped, making it incredibly versatile.
How to use: Cook like rice (1:3 ratio with water) or buy pre-popped. Try 2 tablespoons of popped amaranth mixed with dried fruit before endurance activities.
5. Nutritional yeast: B-vitamin powerhouse for sustained energy
This deactivated yeast is a complete protein loaded with B-vitamins that directly impact energy metabolism. It’s not the same as baker’s or brewer’s yeast—it’s specifically grown for nutrition and has a surprising cheesy, nutty flavor.
The numbers: 2 tablespoons = 8g protein + full spectrum B-vitamins
Research shows athletes consuming yeast products with beta-glucan experienced less post-workout fatigue and better mood compared to control groups. The B-vitamins are crucial for converting food into energy—something athletes need optimized.
How to use: Sprinkle on salads, pasta, or popcorn. Begin with 1 tablespoon daily, working up to 2-3. Look for brands fortified with B12—crucial for plant-based athletes.
6. Pumpkin seeds: The mineral matrix athletes overlook
While everyone’s focused on almonds and peanuts, pumpkin seeds deliver one of the best mineral profiles in the game.
The numbers: 1 ounce = 7g protein + 50% DV magnesium + 25% DV zinc
For athletes, that magnesium means better muscle function, reduced cramping, and improved sleep quality. The zinc supports testosterone production and immune function—both crucial for those pushing their limits.
The result? The kind of deep, restorative sleep that turns today’s workout into tomorrow’s strength.
How to use: Raw or roasted, aim for 1 ounce (a palmful) daily. They’re calorie-dense, so portion control matters.
The bottom line
These six proteins aren’t just alternatives—they’re upgrades. Each brings something unique to the table beyond just protein content. Anti-inflammatory compounds. Performance-enhancing minerals. Recovery-accelerating nutrients.
You don’t need to go all-in immediately. Pick two or three that sound interesting. Experiment.
The old model of “protein = meat” is dead. Elite athletes have already moved on. They’re not choosing these foods because they’re plant-based. They’re choosing them because they work.
Next time you’re at the store, head to the bulk bins. Look for the seeds, the algae, the fermented foods. Your body—and your taste buds—will thank you.
