Here, TrueSport Expert Kristen Ziesmer, a registered dietitian and board-certified specialist in sports dietetics, is sharing a few tips for creating the optimal smoothie.
1. A smoothie should be constructed like a meal
Think of a smoothie the same way that you would think of a whole balanced meal, says Ziesmer. This means breaking your smoothie down into core nutritional components:
- Protein: The cornerstone of every meal for young athletes should be protein, in order to rebuild and replenish muscles.
- Fruit and vegetables: A healthy meal also contains fruits or vegetables, which are packed with micronutrients as well as fiber.
- Simple Carbohydrates: For athletes on the go, adding simple carbohydrates in the form of honey, maple syrup, or even oatmeal can provide the sugars they need to fuel their training.
- Fat: A small amount of healthy fat in the form of nut butter or seeds adds satiety to a smoothie and helps keep your athlete fuller for longer.
- Liquid: Most smoothies will require additional liquid in order to blend. This can be water, milk, or fruit juice depending on your athlete’s preferences.
2. Make prep easy

3. Get the right amounts of each ingredient
The amount of each ingredient does matter, especially when it comes to protein, so measure out your first few smoothies until you can approximate how much Greek yogurt and other ingredients equal a full serving. The same applies to nut butters—check the serving size and scoop appropriately. If nut butter is your sole protein, then Ziesmer suggests a double serving.
As far as fruits and vegetables go, Ziesmer recommends only a handful in order to leave room for calorically dense nutrients. For sweeteners like honey and maple syrup, she recommends not exceeding a tablespoon, particularly if the smoothie already has sweeter fruits like bananas.
4. Properly choose your protein
Protein should be the base of your smoothie,
5. Add your fruit and veggies
Bananas are a traditional smoothie staple, as are most berries, but let your athlete’s preferences dictate the fruits and veggies that you use in their smoothies. Sometimes, a mango-pineapple-coconut milk smoothie with chia seeds and a handful of spinach is just what an athlete wants and needs!
Aim for at least a cup of whatever fruits and vegetables you’re using. Also keep in mind that while spinach blends seamlessly into a smoothie to add nutrients like iron and vitamin K, leafy greens take up a lot of space without providing valuable calories. A handful is plenty, so don’t sacrifice more calorically dense additions like yogurt or peanut butter, especially if the smoothie is replacing a full meal.
6. Use a frozen component

7. Don’t be scared of sweetening your smoothie
As adults, we tend to assume that adding extra sweeteners like maple syrup or honey is just adding empty calories. But for athletes on the go, it’s important to remember that they do need simple carbohydrates, both before and after workouts. “If your athlete just has a fruit smoothie with blueberries, ice, and water, that’s going to leave them feeling hungry again very soon,” explains Ziesmer.
8. Add extras

Takeaway
Smoothies are a great option for busy athletes who need nutrient-dense meals on the go, but they’re only ideal if they contain the right ingredients. Smoothies for athletes should have protein, fruits and vegetables, carbohydrates, and a small amount of fat so that they’re satisfying fuel for active and hungry athletes.
