Adding protein to your green smoothie


Most people are aware of the benefits of eating plenty of fresh fruits and vegetables… yet not everyone knows just how important protein is for your body. Protein is one of the four macronutrients that your body needs on a day-to-day basis (the other three are fats, carbs, and water). Protein is essential for our bodies to work properly.

Why is protein so important?

Because your body burns protein slower than carbs, protein is important to prevent blood sugar spikes that can not only make you feel weak and dizzy, but can also lead to serious health issues down the road.

Also, when your body has enough protein it doesn’t have to resort to burning muscle for the energy it needs, so your muscles stay strong and toned. That’s why drinking a protein-rich smoothie after a workout is an excellent way of replenishing your body!

Here’s our favorite forms of protein:

Nuts and Seeds: You may be surprised to know that tiny seeds—like chia seeds and flaxseed—pack an amazing protein punch. For instance, one ounce of chia seeds contains an impressive 4.4 grams of protein, and they boast a wonderfully nutty taste! Speaking of nutty, nuts are also a great source of protein. Just 1/4 cup of almonds or 2 tablespoons of almond butter will give you 8 grams of protein. Flaxseed is another great alternative, with 8 grams of protein per 1/4 cup. When you choose to add nuts to your green smoothie don’t forget that they’re also higher in fat, so don’t be overly generous!

Protein Powders: If you are looking for a plant-based protein that is free of animal products, your best option is hemp protein or raw vegan protein powder. Feel free to add 2-4 tablespoons to your morning green smoothies! You can buy hemp protein at Trader Joe’s, Whole Foods or even online at

Spirulina (blue-green algae): This plant-based ingredient is an excellent source of protein that can be added to your green smoothies. Be careful, though! The taste is strong, so start off light (by using about a teaspoon) to get used to the flavor, then add more as you can.

Additional protein options include chocolate and vanilla protein powders, whey protein powder, silken tofu, soymilk, non-fat Greek yogurt, cottage cheese, and natural, no- sugar added peanut butter. We prefer to avoid soy and animal products, but that’s just our personal preference; if you enjoy these foods, feel free to use them in your green smoothie creations.


Drinking green smoothies as a meal replacement?

If you decide to drink a green smoothie as a meal replacement, it’s recommended that you add a protein source to your blender, or have a high-protein snack—such as a hardboiled egg or a handful of nuts on the side. If you work out regularly, your protein requirement will be higher, so we recommend that you adjust accordingly.

    Hi. I’m currently doing the 30 day green smoothie challenge and I’m struggling with the protein powders. I prefer to use a powder in my smoothie and I’ve become accustom to whey protein. I have recently learned the benefits of eliminating animal proteins from your diet. With that said, I have started using the Sun Warrior Raw Vegan Protein Powder and the taste in my opinion is bad. I have had both the Natural and Vanilla flavors and been disappointed both times. Will you recommend a Plant Based Protein that is more palatable?

    I am using the green smoothie as a meal replacement for breakfast and lunch to help me lose weight. I did see in another comment from someone else doing the same as me, it was replied to use hemp/brown-rice type protein powders. If I substitute water with almond milk as well as using the protein powder, is that too much with trying to lose weight? or should I stick with water?

      Hi Leslie,

      Thanks for reaching out + great question! When using your green smoothie as a meal replacement we suggest adding protein + healthy fats, no matter the liquid base. Adding protein + healthy fats will ensure you’re fueling your body with a complete meal. Check out our favorite meal replacement booster combos here…

    I am so looking forward to the 30 day challenge. I loves me some green bevvies anyway but I had begun to skulk off and as a result gained 2 stones!! OMG pass me that blender quick!!
    I note in your response to another poster/postee that they should add coconut oil to gain weight – I love the taste of the stuff but I don’t want to gain another lb. Do you recommend I leave it out? I make one smoothie with the Big C and another with Flaxseed…I don’t want to overdo it, my trousers are just soooo tight!! :-(

    Many thanks

      Hi Sarah,

      Adding healthy fats like coconut oil to your green smoothie is a great way to provide your body with a boost of nutrition. When used as a meal replacement adding healthy fats + protein is the way to go to ensure you’re providing your body with a complete meal. Using your green smoothie as a healthy snack when trying to lose weight, you can always skip the coconut oil then.

      Hope this helps!

        It does. Many thanks

    I am fairly new to green smoothies. I am using them to get the veggies I need plus weight loss. My issue is that I am hungry still after I drink a smoothie as a meal replacement. Currently I am adding Chia and Flax seeds, but when I add more, I get too much of a nutty taste. Any suggestions?

    • SGS Rawkstar 12.8.2015 at 4:52 am #

      Hi Matthew,

      Thanks for reaching out! Still hungry even after adding protein + healthy fats to your green smoothie? Your body is trying to tell you something! In addition to your green smoothie enjoy a handful of healthy nuts, hard boiled egg, or another healthy option to get an additional boost of protein. We never want you to feel deprived, so make sure to listen to and fuel your body!

      Cheers :)

    Found this site and I’m all the way in Jamaica but I absolutely love every green smoothie that I have had so far. Never would have given ‘green’ a chance if I hadn’t tried your recipes. They are simple and delicious and helping me with my weightloss journey and they give me a boost of energy too. Thanks so much!!

    • SGS Rawkstar 11.13.2015 at 5:31 pm #

      Hi Giselle,

      Thanks for reaching out! We’re so excited to have you blendin’ with us. Which recipe has been your favorite?

  6. Lindsey 10.28.2015 at 11:59 am #

    Great site :-) I am hoping to lose some weight, but I am breastfeeding and am hungry often. What are some vood smoothies to keep full and shed some pounds? Also, if I want nonfat greek yogurt in a smoothie, how mvh am I using, and what am I ommiting?

    • SGS Rawkstar 10.28.2015 at 1:26 pm #

      Hi Lindsey,

      Thanks for joining us! I can definitely relate to the hunger that breastfeeding creates. I once told my husband I couldn’t talk to him because I was too focused on being hungry when our son was first born.

      That’s why we love green smoothies! They’re the perfect quick snack when you’re busy with baby. What’s even better, when you add protein they’ll help you stay full longer! Using green smoothies as a healthy snack option definitely helped me work back to my pre-baby body. Looking to lose the weight? We definitely suggest focusing on what you’re putting in your body (like healthy + nutritious green smoothies), over limiting calories. You and baby need them! :)

      We personally don’t add dairy products to our green smoothies. Dairy is the #1 undiagnosed food allergy and can be pretty tough on your digestion. For that reason we avoid it. But it’s all about deciding what’s best for you + your family. Greek yogurt is a great source of protein. When adding to your green smoothie, no need to replace anything, just add it to the mix! :)

    Hi! Great site and exactly the information I needed this week! What would you recommend for some one who needs to gain weight?

  9. Mirka 8.26.2015 at 5:22 am #

    Hi ladies,
    any experience with quinoa flakes? They seem to be high in protein and do not leave gritty texture.

    Thank you

    • SGS Rawkstar 8.26.2015 at 7:06 am #

      Hi Mirka,

      Yum! I personally haven’t tried quinoa flakes, but love that they’re naturally gluten-free + packed with iron, b-vitamins + protein!

      Cheers :)

    I want to make Green Smoothies as meal replacements for breakfast and lunch….. but I struggle with which protein powder is best for weight loss and not weight gain – which protein powder doesn’t make you gain weight but instead helps you lose weight?

    • SGS Rawkstar 8.26.2015 at 5:31 am #

      Hi Mira,

      Looking for a great protein powder, we love reaching for plant-based protein options like hemp or brown rice protein powders!

      Hope this helps!

    First I have to say I love this website :)!
    Just wondering, I made a green smoothie with cashew nuts the other day, and really hated tasting the structure of ground nuts in my drink… I already soaked them before blending, any other tricks to get around this? or should i just opt for another protein source?
    Thanks for your advice!

    • SGS Rawkstar 5.22.2015 at 2:27 pm #

      Hi Judith,

      Blendin’ nuts will always give you a slightly gritty texture, if you’re interested in a smoother consistency we suggest trying a nut butter in place of whole nuts or other protein source.

      Hope this helps! :)

      • judith 11.27.2015 at 7:18 am #

        Soaking nuts brings out flavor and higher nutrition. They blend perfectly. Especially cashews.

        Thanks for sharing, Judith!

  13. amie 4.9.2015 at 12:32 pm #

    Hi. What about LSA as protein and if so how much of this would you have to make the smoothie a meal replacement? Thanks in advance.

    • SGS Rawkstar 4.10.2015 at 3:04 pm #

      Hi Amie,

      I would refer to the manufacturer to see the proper meal replacement serving to add to your smoothie.

      Cheers :)
