20 Muscle-Building Foods That Will Boost Your Strength Naturally

19. Peas: Not Just Side Dish Filler

Green peas may seem humble, but they offer around 8 grams of protein per cooked cup and are rich in iron, magnesium, and B vitamins. They’re a solid base for many plant-based protein powders due to their high lysine content—an amino acid essential for muscle repair. Their starchy nature provides clean-burning carbs for energy, while their fiber supports digestion and fullness. Toss into salads, blitz into soups, or mash with avocado for a vibrant, muscle-friendly side.

20. Spirulina: The Superfood Shortcut

Spirulina is a blue-green algae with a cult following—and for good reason. Just one tablespoon provides 4 grams of protein, iron, magnesium, and potent antioxidants like phycocyanin. It enhances endurance, reduces oxidative stress, and improves immune response, making it perfect for active recovery. Its bioavailable protein supports muscle repair, especially in plant-based diets. Mix spirulina into smoothies or energy balls for an easy, high-impact upgrade to your nutrition stack.
