Plant-based protein powder is on the rise, and for good reason. People are taking control of what they put in their bodies, and turning to vegan protein powder as a cleaner option. I’m here to break down what kinds protein bases are the best (and worst)… as well as explain why hemp protein powder won’t make you high.

You might also like my Homemade Protein Powder recipe, which I add to most of my smoothie recipes to turn them into a meal replacement or post-workout recovery drink. If you’d rather buy a plant-based protein powder, I suggest Ritual Protein or Complement Essential.

The Importance of Protein

Protein is used to build and repair tissue (like muscle). It also helps the body create hormones, enzymes and other essential chemicals, and, bottom line: makes your hair, skin, and fingernails look great. Basically your whole body needs protein to function properly.

Yet the body also needs carbs + healthy fat to help break down the protein you just ingested. So when you are looking for a great plant-based protein powder, look for one that also has fat as well as fiber to help break down that protein.

Who Should Use Protein in Smoothies?

Let me be clear: bodybuilders don’t own the rights to protein powders (vegan or otherwise). Any active athlete looking for an easier way to increase their protein intake should consider using a protein powder. Those who regularly work out need double the amount of protein over those with a more sedate lifestyle. It’s also helpful for people looking to…

  • Increase muscle mass
  • Lose weight
  • Lower cholesterol or blood pressure
  • Strengthen the immune system
  • Make quick healthy meals

If you said yes to any of the above, then a protein powder supplement might be right for you. Protein boosted smoothies can help you:

  • Gain Muscle. This is probably the most widely known benefit of protein powders. Added protein helps muscles rebuild faster after a workout. Because of the direct ways protein affects the muscles, the best time to consume protein powders are after a workout.
  • Lose weight. Protein is also a great way to stop any unwanted snacking. You stay full longer after that green smoothie when you boost it with plant-based protein powder. It also boosts the metabolism, burning fat and keeping cholesterol and blood pressure levels low.
  • Protect the Immune System. Protein doesn’t just strengthen muscles, it also strengthens every cell in the body. This makes them less likely to be infected- keeping you strong and healthy.
  • Commit to a healthy diet. Using a protein powder with healthy fats can turn a daily smoothie into a meal replacement. This is truly the healthiest “fast food” there is as well as an easy habit to embrace daily.

Shakes and smoothies are the best way to consume protein powders. I love adding hemp protein powder to my daily smoothie, workout or not. It helps me stay full longer and be more productive with my day, as well as help me recover faster from a workout.

Best Protein for Smoothies

After years of trying to find a powder that I enjoyed adding to my smoothies, I gave up. It didn’t exist. There was either too much junk in it, or not enough of the right stuff. I went on a quest to create my own powder that I could use every day and love how it tasted, what was in it and the results I got. And I couldn’t be happier with the outcome.

I really do love my homemade protein powder recipe. It isn’t gritty, tastes good in a fruit smoothie and contains all 9 essential amino acids. I think you’ll be pretty impressed with it.

If you’re looking to buy a plant-based protein powder to add to your smoothies, I suggest Ritual Protein or Complement Essential.

What Makes Protein Powder Vegan?

Protein powders most commonly start from whey protein, casein, or soy. Whey protein as well as casein comes from dairy. If you have any kind of dairy intolerance, then be sure to check the label on your protein powder! These are not naturally occurring ingredients, so I lean toward plant-based protein powder.

Vegan Protein Options

Soy based protein powders are the number one vegan protein powder option. Soy is a complete protein, yet is a bit controversial in terms of helping or harming the body. I take an even more natural route in using hemp protein powder.

Hemp protein is also a complete protein, yet it ranks even higher than soy in terms of quality. It not only contains all 9 essential amino acids, it also contains healthy fat and fiber, as well as other essential minerals. Hemp protein powder starts out with a slightly nutty flavor, so no need to cover up the taste like you do with whey, casein, or soy based powders.

A side note: while hemp is part of the same plant family as marijuana, it contains little to no THC and therefore does not have any mind-altering effects.

Healthy sources of nutrition

Heavy Metals in Plant-Based Protein Powder

Protein powders can also contain heavy metals like arsenic, lead, and cadmium that easily build up in the body. These known carcinogens are harmful to the immune system. These elements are found in our soil (which in turn grow in plants that cows eat or plants grow into). You cannot completely avoid it, yet you can be aware and use brands that test their levels and are conscious of this.

Oftentimes, heavy metals go unnoticed because protein powders are considered a supplement and do not need to be approved by the FDA. Your protein powder brand should pay for “heavy metal testing” as well as easily disclose the results to you when asked. As you can see, it’s not easy to find a vegan protein powder for smoothies that you can feel really good about!

By grinding up the plants, the nutrients are pre-digested and ready for your body to absorb immediately. The vitamins, amino acids, and minerals become easily accessible to the body. Plant-based protein powders can give you the same results that other powders do. They just leave out all the antibiotics, toxins, and lactose.

Now, time for you to spill all your protein secrets with me! Please share in the comments your fav protein to add to smoothies, or what you’re looking for (and not finding) in a vegan protein powder.

  1. How do I purchase simple green protein smoothie boost meal replacement? I’m in the autumn cleanse 21 day challenge.

  2. Hello! You mention adding “protein boost” to the smoothie and I see in the pictures a product called “Simple Green Smoothies Protein Boost” – where can I purchase that product? Thank you!

    1. Hi Melodie! Unfortunately we don’t sell Protein Smoothie Boost anymore, due to the rise in production costs. We didn’t want to pass on these high costs to our loyal rawkstars so we decided to pull it. The Homemade protein powder is a great substitute!

  3. Can you please tell me which one of these ingredients bring the ‘green’ colour to the powder mix – thank you

  4. 3 stars
    Because the shipping is too expensive to Germany, I tried this recipe. Grinding the seeds was hard work, but I managed. It’s not a fine powder and the color is dark brown, but in the smoothie it doesn’t look bad. In the description of the smoothie boost it tells that it is tasteless and doesn’t change the flavor of the smoothie. Well the selfmade protein powder is not tasteless, it brings a bitterness, which I don’t like in every smoothie. When I use only chia or hemp hearts I don’t taste them so much, so I think I’ll stick with that. But thanks for giving everybody a recipe to try.

    1. Wow, Silke! You did it! Way to go! I’m so glad you got to try making your own version of homemade protein powder.
      I’m sorry it turned out to be a little bitter. I find that homemade protein powder adds a bit of a nutty flavor to some of my smoothies. It’s so awesome that you gave it a shot though! You totally RAWK!!

  5. 5 stars
    Our family loves homemade protein powder! It doesn’t change the taste of our smoothies + I feel safe giving it to my toddler. Win-win.

  6. Do you ever mix greek yogurt with your plant-based protein powder? I’m curious if it would be a good way to get more protein and creaminess.

    1. Cool question, Lalila! While we haven’t tried it here at SGS, it sure would be an interesting experiment. Adding berries and/or banana to that combo would be good, as our homemade protein powder and the best greek yogurts aren’t sweetened.

  7. Hands down, my favorite protein powder. So clean, doesn’t clump, and isn’t chalky. Great job!

  8. Hello,
    Great tasting powder !
    Can you tell me the ratio between the three ingredients in the homemade protein powder?

    Thank you, Laurie

    1. Thanks for loving our homemade protein powder! Since it’s a proprietary blend, we’re not able to share the ratios at this time. Yet we can def say it’s 10g of clean protein per serving! 🙂

  9. Hi, I own your Simple Green Meals cookbook. Within the Cacao Crush Smoothie you recommend a service of Daily Blends Cacao Powder . I cannot find where I can purchase or make that powder. I saw your rawkstar tip and it is a good substitute, but I really would like try the Daily Blends cacao powder.
    Can your recommend who I should go to purchase it?

    By the way, I love both your books and hope you do another meal book.

    1. Hey Teresa! We no longer carry the Daily Blends Cacao Powder but we have an awesome new product called homemade protein powder that’s even better! For the Cacao Crush Smoothie, I suggest using a serving of our homemade protein powder, 1 Tbsp of raw cacao powder, and 1 tsp of pure maple syrup. 🙂

  10. Is the Green Protein mix substituting for the spinach in a smoothie, or do you put both of them in the smoothie?

    1. Hi Kathy, great question! We usually put both spinach and our homemade protein powder in our smoothies. 🙂

    2. Hello,
      How much non-fat Greek yogurt should I add to the two smoothie recipes and would that mix well with those recipes that call for water?

      1. Hey Christine! We love using non-dairy options in our smoothies as dairy is one of the top undiagnosed food allergies and can be pretty tough on the digestive system. If you enjoy dairy + the way it makes you feel, feel free to add it to your smoothie. I’m just not sure how much you should use. 🙂

  11. Would 2 Tablespoons of ground flaxseed be an adequate amount of healthy fat plus protein for a meal replacement?

    1. Hey Allison,

      That sounds like a great swap for adding some healthy fats to your diet. You could also add chia seeds too if you prefer.


  12. I”m having jaw surgery and will be on a liquid diet for about 9 months. I think the green smoothies are a great option for me, but want to make sure I’m consuming enough calories. Do you have calorie counts for each of your smoothies?

    1. Hi Jennifer,

      How are you doing after your surgery! I’m sending plenty of healing vibes your way + wishing you a speedy recovery. We try not to focus on the numbers, and instead focus on the ingredients we’re fueling our bodies with. When you’re restricted to a liquid diet, I can definitely see how calorie count can be important. Two great options are the app My Fitness Pal and

      Hope those help!

  13. Mona, look at the Keto diet, my wife was diabetic, for years and no longer on meds for it. Don’t look at it as a diet look at it as a way of eating. My wife loves to cook and we are eating more deserts now than we ever did, they are just made to be healthy for us and they taste really good too. We went on the Keto diet and her blood sugars and A1C are back to a normal range after about six months and the doctor took her off all her diabetes meds about four months ago. She still checks her blood daily, on a normal morning blood test now her sugar level is about 95-105, before even on the meds it was 115+. My wife has been able to drop about 25 pounds and I dropped 35, it was easy for me and harder for her. It wasn’t a fast drop it was a slow and steady drop. An interesting note, the doctors husband was a severe diabetic after following this type of diet for a while he to is off his meds. This happed before we talked to the doctor about it so she was all for us trying it. Not all doctors will have an open mind about this type of diet, some will look at it as a alternative treatment that is not taught in med school so they won’t even think about trying something different. They just keep pushing the meds. I am not a doctor this is not to be taken as medical advise
