5 Best Plant-Based Protein Powders for Weight Loss

Emma-Kate Lidbury

|

If you’re looking for a good plant-based protein powder to help you achieve your weight loss goals, you should pay attention to:


  1. The amount of protein the powder contains
  2. The calorie content
  3. Whether it provides a complete source of protein

Protein helps with satiation, helping you feel fuller for longer. It also helps with building muscle, which can help improve your body composition.


Pea and rice proteins are the ideal source of protein for plant-based options. While pure pea proteins technically have all nine essential amino acids, they’re low in one of them—methionine.


Rice protein is a viable source of plant-based protein, especially popular in vegan and vegetarian diets. Although it does not have as complete an amino acid profile as animal-based proteins, it is relatively high in essential amino acids, particularly when combined with other protein sources like pea protein. Additionally, rice protein is hypoallergenic, making it suitable for people with allergies to dairy, soy, or gluten.


It’s advisable to look for a brand that balances all three of these—high protein content, optimal calorie content, and a complete source of protein—while also offering a high-quality product. While it can be easy to just focus on the lowest calories, sometimes this comes at the expense of unwanted additional ingredients, such as gums and artificial sweeteners, which we think are better to avoid.


To help you save time in your search, let’s look at four of the best plant-based protein powders for weight loss. We’ll start with our own at Momentous.


1. Momentous 100% Plant Protein

  • Number of Servings: 20

  • Serving Size: 1 scoops (37.7 grams)

  • Flavors: Two - Chocolate, Vanilla Chai

  • Protein per serving: 20g

  • Calories per serving: 140


Pros:

  • Third-party tested through NSF and Informed Sport

  • Trusted by professional and collegiate athletes

  • Purposely not organic, which means fewer heavy metals

  • Great taste and mixability

  • Complete amino acid profile

  • Also available in convenient travel packs


Cons:

  • Cost - it’s one of the more expensive options

Momentous 100% Plant Protein is one of my favorite tasting plant proteins. In my experience, many plant-based protein powders don’t mix well or taste good, so when you find one that does, you quickly appreciate it.


Available in both chocolate and vanilla chai flavors (the chocolate is my go-to), this protein powder is ideal for including in any post-workout smoothie, and I’ll often throw it into the blender together with water or almond milk, collagen, creatine, a banana, and a spoonful of almond butter.


It’s formulated with rice and pea protein, which means it delivers a complete amino acid profile, unlike other plant-based protein powders that fall down here.


The fact that it is purposely not organically sourced gives peace of mind about it containing higher levels of heavy metals (organic soil contains higher heavy metal content). This, combined with certifications from NSF Certified for Sport and Informed Sport, means it’s trusted by professional and collegiate athletes and hugely popular with fitness enthusiasts of all ages and abilities.


It’s also available in convenient travel packs, which are perfect for days when you’re on the go from gym to the office or when you’re traveling and want to stay consistent with your protein and supplement regime.


At 140 calories per serving—with 20 grams of protein—it packs a great punch that will help anyone looking to hit body composition goals. While it is one of the more expensive powders on the market, which means it might not be the right fit for someone on a tight budget, it is an ideal option for anyone wanting a premium plant-based protein powder. 

2. Now Sports Nutrition Pea Protein Powder


Key Things to Know About This Product

  • Protein Source: Plant-based protein (pea protein isolate)

  • Artificial Sweeteners: No

  • Gluten Free: Yes

  • GMO Free: Yes

  • Certifications: Informed Sport

  • Free shipping: Yes - on orders $50+

  • Subscription: Subscribe & Save option available on Amazon; save up to 10% on orders of 5+ products 



Product Details:

  • Price: $36.99

  • Net Weight: 2 lbs

  • Number of Servings: 21

  • Serving Size: 1 scoop ( 44 grams)

  • Flavors: Three - Creamy Chocolate, Vanilla Toffee, Unflavored

  • Protein per serving: 24 grams

  • Calories per serving: 160


Pros:

  • Cost-effective

  • Third-party certified

  • No artificial sweeteners


Cons:

  • Chalky taste

  • Includes xanthan gum and xylitol


Now Sports Nutrition Pea Protein Powder is a popular vegan protein powder for athletes and fitness enthusiasts looking for a complete protein. At 160 calories per serving, it has a slightly higher calorie content than the Momentous product, but it does deliver 24 grams of protein plus a blend that includes BCAAs (branch chain amino acids).


Sourced from yellow pea protein isolate, it is a complete source of all nine essential amino acids. But while it scores well here, it doesn’t do so well on taste and mixability. The chocolate flavor has a chalky taste and texture, which can make it hard to get down. But as far as plant-based protein powders are concerned, it’s certainly not the worst we’ve tasted!


Priced at $36.99 for a 2-lb tub, it’s one of the more cost effective options and will certainly suit those on leaner budgets. With an Informed Sport certification too, it gives the peace of mind that comes from reputable third-party testing. It’s definitely not our favorite option, but does deliver good-quality plant-based protein for a reasonable price.

3. Vega Essentials Plant-Based Protein Powder

Key Things to Know About This Product

  • Protein Source: Pea protein

  • Artificial Sweeteners: No

  • Gluten Free: Not stated

  • GMO Free: Yes

  • Certifications: No

  • Free shipping: Yes - on orders $50+ 

  • Subscription: Yes - save 20% on subscription


Product Details:

  • Price: $46.99

  • Net Weight: 1 lb 5.9 oz

  • Number of Servings: 18 

  • Serving Size: 1 scoop (34 grams)

  • Flavors: Vanilla, Chocolate, Berry

  • Protein per serving: 20 grams

  • Calories per serving: 150 


Pros:

  • Popular vegan option

  • Low sugar content and zero added sugar

  • Packed with vitamins and minerals


Cons:

  • Price

  • No third-party testing


Vega Essentials Plant-Based Protein Powder is a popular option among vegans looking to hit their optimal protein intake each day. Sourced from pea protein with zero added sugars, it provides 20 grams of protein per serving helping to keep you full and satiated. It’s available in three flavors—vanilla, chocolate, and berry—which don’t taste as good as the Momentous product (although that could come down to personal preferences), but they do mix reasonably easily.


At $46.99 for 18 servings, it’s one of the pricier options on the market, but this particular plant-based protein is also packed with a hefty number of vitamins and minerals, so it comes close to being a protein and greens formula in one.


Given there’s no third-party testing conducted on this product and it has a higher price tag, it’s hard to justify opting for this one over the Momentous 100% Plant Protein in my opinion.

4. Orgain Simple Organic Plant-Based Protein Powder

Key Things to Know About This Product

  • Protein Source: Plant protein - pea protein, pumpkin seed protein, almond protein

  • Artificial Sweeteners: No

  • Gluten Free: Yes

  • GMO Free: Yes

  • Certifications: No

  • Free shipping: Yes - on orders $75+ 

  • Subscription: Yes - save 15% on subscription


Product Details:

  • Price: $34.19

  • Net Weight: 1.25 lbs

  • Number of Servings: 15

  • Serving Size: 2 scoops (38 grams)

  • Flavors: Creamy Chocolate, Vanilla, Peanut Butter

  • Protein per serving: 20 grams

  • Calories per serving: 150


Pros:

  • Clean, simple ingredients

  • GMO and gluten free

  • Good taste and mixability


Cons:

  • Organic, which can mean higher heavy metal content


This plant-based protein powder from Orgain is popular for its great taste and mixability, which can be a rare find. The Creamy Chocolate flavor mixes well in post-workout smoothies with good texture and after-taste.


The formula is deliberately simple, as Orgain states on its website: “We put a lot of thought into our shake and not a lot of ingredients. Seriously—it’s as simple as that. This deliciously clean, plant-based protein powder is made from just a handful of high-quality ingredients with names you can pronounce.”


It delivers 20 grams of protein per serving and 150 calories, so it is comparable with other products and favorable for those looking to achieve weight loss goals and/or build muscle mass.


It is certified organic, which while ordinarily a good thing, in a plant-based protein powder it can lead to higher levels of heavy metals as organic soil typically contains higher levels of heavy metals.
