- Steady energy: Oats and banana provide complex carbs and potassium, supporting endurance and recovery.
- Heart-healthy fats: Peanut butter, hemp, chia, and flax add omega-3 and omega-6 fatty acids for joint and heart health.
- Digestive support: Fiber from oats, seeds, and banana keeps digestion smooth and helps you stay full longer.
- Micronutrient boost: Spinach or kale adds iron, folate, and vitamin K; cocoa contributes antioxidants.
What Not to Do

FAQ
How much protein is in this smoothie?
With soy milk, a standard scoop of vegan protein powder, hemp or chia seeds, and peanut butter, you’ll typically land around 30–40 grams of protein per serving. Exact numbers depend on your brands and measurements.
Can I use almond milk instead of soy milk?
Yes, but note that soy or pea milk usually has more protein.
If you switch to almond milk, consider a higher-protein powder or add extra hemp seeds to keep your protein goal on track.
Do I need a high-speed blender?
It helps, especially with oats and frozen fruit, but it’s not mandatory. If your blender struggles, let the oats soak in the plant milk for 5–10 minutes first and slice the banana thinner.
Is this good before or after a workout?
It works for both. For pre-workout, drink it 60–90 minutes before training.
For post-workout, have it within 1–2 hours to support recovery.
Can I make it without banana?
Absolutely. Use 1 cup frozen cauliflower rice or 3/4 cup frozen mango for thickness. You may want a small amount of sweetener to balance flavor.
What protein powder should I use?
Choose a pea, soy, or blended vegan protein with at least 20 grams per scoop and minimal added sugar.
Pick chocolate or vanilla based on your flavor direction.
How can I add creatine or other supplements?
Stir in 3–5 grams of creatine monohydrate or blend it directly. It’s flavorless and mixes well. Always follow label guidance for other supplements.
