Sometimes, fruit, juice and ice just aren’t enough. For instance, when I’m recovering from an intense workout or creating a health packed meal replacement, I like to add a little protein and fiber to my smoothies. When I’m coming down with a cold, I like an antioxidant boost and when I’m making a breakfast smoothies, sometimes I like a little added crunch!
If you’re trying to determine whether your smoothie needs a little something extra, here are some guidelines to help you choose: 
PROTEIN
Whey/soy based proteins: these are great if you want to add muscle quickly
Nut Butters: use any type of nut butter (peanut butter, almond butter, cashew butter, etc) for added protein and flavor
Shelled flaxseed or hempseed: seeds are a healthy way to add protein, fiber and omega fatty acids
MEAL REPLACEMENT PACKET
If you’re going to include a meal replacement, you may need to increase your liquid base by 1-2oz and will likely need a bigger glass. Some great meal replacement packets include:
Amazing Grass
Vega
Kashi Go Lean
LIQUID OMEGA OILS
Liquid omega oils are a great source of heart healthy omegas. Some healthy liquid omega oils include:
Hemp Oil: adds healthy protein and omegas without the crunch of hempseed
Flaxseed Oil: adds fiber, protein, and omegas without the crunch of flaxseed
WHEAT GERM
If you don’t have any gluten allergies, wheat germ is a very effective way to add fiber , protein and important nutrients including : iron, potassium, zinc, magnesium, riboflavin and vitamins A, B1, and B3.
