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. 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.
Smoothies to Add Plant-Based Protein Powder
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.
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.























hi again, just wanted to say how helpful your websight is. thank you so much. One more question. Last time we were in the store we switched from our powdered protein to a protein shake. Says it has 30g protein 160 cal. 1 g sugar 24 minerals. It’s vanilla flavored. It, like I said makes everything taste better but, I don’t really feel good about it. Seems more like a milk shake. what is your opinion of the liquid vs the powdered. Thank you so much. kitty
Hi Kitty,
When it comes to our green smoothies we always think simple is better! After all, we’re Simple Green Smoothies! For that reason we try to stick with protein powders that have few to no additives. One of our favorites is hemp protein powder by Nutiva, it only has one ingredient!
Hope this helps!
Hi, you’ve said nuts are good for you, of course, but high in fat. What about seeds? My husband and I started making smoothies but have to be careful not to overdue the fruit smoothies. I’m looking for more veggie smoothies. I’m afraid of getting too attached to some protein powders that make you smoothies taste so good no matter what else is in it. Thinking there must be sugar in it.
Hi Kitty,
We love seeds! Two of our favorites are sunflower + pumpkin and both offer a protein punch! Worried about the sugar content of our recipes? Check out our favorite low-sugar fruit options here…

Do you actually put the sunflower or pumpkin seeds in the smoothie as a protein? Or do you just eat them on the side?
Hi Rach,
Great question! Feel free to do either! You can blend the seeds right into your green smoothie, or enjoy them on the side!
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?
Thanks!
Hi Caroline,
Thanks for joining our 30-Day Green Smoothie Challenge and reaching out! Looking for a new plant-based protein powder. We love reaching for Nutiva Hemp Protein Powder…
Vega Protein Powder is another great option, that we’ve heard from a lot of our community!
Hope this helps!
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…

Hullo
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
Rawesome! 🙂
