matcha: if you're a green tea lover, you can add a teaspoon of matcha to your smoothie for green color, antioxidants and earthy flavor.
flaxseed meal: this is one of my favorite ingredients to add to smoothies for a little boost of fiber and minerals, and is especially great for nursing mamas as flaxseed can help increase milk supply. Usually a tablespoon is plenty!
chia seeds: feel free to add in a tablespoon of chia seeds to your smoothie for a boost of healthy fats and fiber.
hemp seeds: if you've been wondering what to do with those hemp seeds lurking in your cupboard, feel free to throw in a tablespoon into your smoothie for a boost of healthy fats, omegas and minerals.
protein: make this a post-workout smoothie and boost the protein by adding 1/2 cup greek yogurt or 1 scoop of your favorite protein powder.
