6 Smoothie Add-Ins for More Flavor and Nutrition

Smoothies are an easy way to combine several foods in one glass, but the ingredients you add can make a big difference in how filling and nutritious they are. A few simple additions can bring more protein, fiber, healthy fats, or vegetables to an otherwise basic fruit smoothie. The best part is that many of these ingredients are inexpensive, easy to keep on hand, and simple to blend in. Here are several practical smoothie add-ins worth keeping in your kitchen.

Chia Seeds

Chia seeds are an easy way to add fiber, protein, and plant-based omega-3 fatty acids to a smoothie. Two tablespoons provide about 11 grams of fiber along with protein and unsaturated fat, making them a particularly nutrient-dense addition. They also absorb liquid as they sit, which can give a smoothie a thicker, more substantial texture.

Greek Yogurt

Plain Greek yogurt can add a significant amount of protein while giving a smoothie a thicker, creamier consistency. Yogurt is made with live cultures, although the specific amount and whether cultures remain active through the product’s shelf life can vary, so check the label if live cultures are important to you. Choose plain yogurt when you want to control the sweetness, or use a flavored variety when convenience matters more.

Nut Butter

A spoonful of peanut, almond, or cashew butter adds richness along with protein and unsaturated fats. Nut butters can also make a fruit-based smoothie more substantial, particularly when paired with ingredients such as yogurt or milk. For a simpler ingredient list, look for varieties made primarily from nuts and with little or no added sugar.

Flaxseed (Ground)

Ground flaxseed blends easily into smoothies and provides fiber, protein, and alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid. Ground flax is generally more useful in smoothies than whole flaxseed because grinding makes its nutrients easier to access. Start with a small amount and increase it as desired, since flax’s high fiber content can noticeably change the texture of a smoothie.

Protein Powder

Protein powder can be a convenient option when you want to increase the protein content of a smoothie without adding much volume. Whey, pea, soy, and other protein powders can work, depending on your dietary preferences and the flavor of the smoothie. Since protein powders are dietary supplements rather than conventional foods, compare the Nutrition Facts and ingredient labels instead of assuming every product has the same nutritional profile.

Frozen Cauliflower

Frozen cauliflower is a surprisingly useful smoothie addition when you want more vegetables without adding much sweetness. Its relatively mild flavor works well with berries, bananas, cocoa, nut butter, and other strongly flavored ingredients, while blending gives the smoothie a creamy consistency. Use plain frozen cauliflower rather than a seasoned or sauced product, and start with a small handful until you find the amount you prefer.
