A medium banana has about 1.3 grams of protein , so it’s a low‑protein food and not a main protein source in your diet.

Quick Scoop

  • Small banana (about 100 g): ~1.1 g protein.
  • Medium banana (about 118 g): ~1.3 g protein.
  • Large banana (about 136 g): ~1.5–1.6 g protein.
  • Per 100 g of banana: ~1.1 g protein.

In other words, a banana gives you a little protein plus useful nutrients like potassium, vitamin B6, vitamin C, fiber, and quick‑release carbs for energy. It’s great as a carb‑and‑micronutrient snack, but for muscle building or high protein goals, you’d want to pair it with something richer in protein such as Greek yogurt, eggs, or nut butter.

Mini sections

Is a banana a good protein source?

Not really. Bananas are considered low in protein compared with foods like chicken, eggs, yogurt, tofu, or lentils. A medium banana covers only about 2–3% of a typical 50 g daily protein target.

When does a banana still shine?

  • Pre‑ or post‑workout snack for quick carbs and potassium.
  • Easy-to-digest energy if you don’t feel like eating a heavy meal.
  • A “base” in smoothies where you add protein powder, yogurt, milk, or nut butter to boost protein.

Example : A smoothie with one banana, Greek yogurt, and peanut butter can turn that tiny 1.3 g of banana protein into a high‑protein snack overall.

Tiny multi‑view: how people use bananas for protein

  • Fitness folks: Usually don’t count banana protein, but use bananas as carb + potassium alongside real protein (whey, eggs, yogurt).
  • General health crowd: See bananas as a convenient, nutrient‑dense fruit and focus less on the low protein content.
  • Plant‑based eaters: Often pair bananas with nuts, seeds, or plant protein powders for a more complete amino acid profile.

SEO bits

  • Main phrase: how much protein in a banana appears clearly with numbers above.
  • Context: In 2025–2026, discussions around banana protein mostly frame it as “low but useful when paired with higher‑protein foods,” especially in smoothie and snack recipes trending in fitness and wellness spaces.

TL;DR:
A banana has only about 1.3 g of protein per medium fruit , so enjoy it for energy, potassium, and vitamins, but look elsewhere for serious protein.
