Plus, GGR Everything lead reviewer Lindsay Sheele, CPT, offers her firsthand insights using Legion Plant+, covering everything from flavor to side effects. Let’s dig into it!

A Quick Look at Legion Plant+

Legion Athletics has become a top pick at GGR, from pre-workouts to protein supplements. Lindsay was so impressed with Legion’s grass-fed whey isolate protein powder that she dedicated an entire video to it (without being approached by Legion).

So, to clarify, our enthusiasm for Legion isn’t driven by financial incentives but rather a genuine belief in their science-backed, third-party-tested products, including Plant+. We also still acknowledge a few aspects to consider before purchasing. 

Before You Buy

  • New to plant proteins? Prepare for a noticeable shift in flavor and texture.
  • Important allergen info: Plant+ contains tree nuts and may be cross-contaminated with milk, eggs, fish, shellfish, peanuts, wheat, and soybeans. While the Amazon product page states it’s gluten-free, this detail is unspecified on the Legion website. 
  • Savings tips: Bulk purchases and subscribe and save options are available, potentially saving you up to 30%. Legion also regularly updates sales on their site and GGR has a Legion Athletics coupon code.
  • Unmatched return policy: Legion offers a full refund on your first order if you’re unsatisfied (without returning the protein)!

Is Legion Plant+ Worth It?

At $2.50 per serving, Legion’s Plant+ is at the pricier end of other plant-based protein powders. However, its high ratings in key areas suggest it may be a valuable investment.

Experience Using Legion Plant+

GGR Everything Lead Reviewer Lindsay Sheele tried the Apple Pie flavor. While she thought the apple flavor was a bit lackluster, and certainly not her beloved Whey+ Cinnamon Cereal, its addition of cinnamon and its overall solubility were noteworthy—see “Taste and Solubility” below for these details. 

Price Per Serving

A 20-serving container of Plant+ costs $49.99, equating to $2.50 per serving before taxes. The cost is comparable on third-party seller sites, including Amazon and Walmart.

The average cost per serving of the best vegan protein powders we’ve tested is about $1.92, ranging from $0.81 to $3.00 per serving. With Plant+ costing on the higher end at $2.50 per serving, we rate it a 1 out of 5 in this category.

However, Legion also offers a rewards program for future savings and various multi-pack and subscription options at discounted rates. A recurring order of a five-pack is the most economical option, bringing the cost down to $2.00 per serving.


The Plant+ formulation earns its 5-star rating, providing 24 to 25 grams of protein per scoop. Let’s dig into the details of this plant-based protein.

Pea and Brown Rice Protein Blend

Most plants are incomplete proteins, except for a select few like pea protein, meaning they lack at least one essential amino acid (EAA). The body needs EAAs, including the branched-chain amino acids (BCAAs), to leverage vital functions and benefits of protein—like supporting bodybuilding and weight loss goals.

Plant+ strategically combines pea protein and brown rice protein for one core reason: to provide a complete protein. “But Sydney, you just said pea protein is a complete protein…” You’re right, but please hear me out!

While pea protein is technically complete, research1 shows it’s low in the EAA methionine. Brown rice is high in methionine, so blending the two provides a more comprehensive acid profile. Brown rice and pea protein powders also provide leucine, the BCAA known for its muscle-building properties, similar to casein protein.

Other Ingredients

Although ingredients slightly vary based on flavor, Plant+ also contains:

  • Organic pea creamer: The creamer is a mix of organic ingredients like coconut oil, rice syrup solids, pea protein, and sunflower lecithin enhances stability, texture, and shelf life.
  • Natural flavors: Despite the term “natural flavors” broadly encompassing various plant and animal derivatives, we assume these are from plants.
  • Salt helps extract the pea protein2 while enhancing the flavor of the protein powder.
  • Natural sweeteners, like stevia leaf extract and monk fruit, add sweetness.
  • Gums, including xanthan and guar gums, offer a creamier texture.

Taste and Solubility 

Lindsay tried the Apple Pie flavor and rated its taste a 4 out of 5. Even though Plant+ is formulated with natural sweeteners and flavors, Lindsay said it has a “very sweet and artificial flavor. The apple flavor was a bit lacking, but the cinnamon taste saved it. Not bad, but will probably be too sweet for some.” 

Looking into an open bag of Legion Plant+ Protein Powder

Although the texture of plant protein powders isn’t as smooth or creamy as casein or whey protein powder, Lindsay rates Legion Plant+ a 5 out of 5 for its solubility. “I mixed it with oat milk and it had a good texture, not too thick either,” she said.

Side Effects

Aside from our testers noting Legion Plant+ wasn’t very filling, no side effects were noted. However, while convenient and quick, protein shakes aren’t always the most satiating (filling) and shouldn’t be used as meal replacement shakes in most cases. 

Third-Party Testing 

Though Legion is certified by Labdoor, an independent supplement certification company, Plant+ has yet to be tested by them. But fret not! It’s third-party tested by an ISO 17025-accredited lab, with its certificate of analysis available online, and produced in NSF-certified, FDA-inspected, and cGMP-compliant facilities in the U.S.

Legion Plant+ vs KOS Organic Plant Protein 

KOS Organic Plant Protein

KOS Vegan Protein Powder

GGR Score: 4 starstarstarstarstar

Product Highlights

  • Multi-source vegan protein powder 
  • USDA-certified organic, soy-free, gluten-free, dairy-free, non-GMO
  • Digestive support via DigeSEB to help maximize absorption

Pros & Cons


  • Manufactured in the USA
  • Superfood-infused
  • 20 g protein per serving
  • Chocolate flavor is rich
  • Enhanced with digestive support enzymes
  • Under $1.50 per serving


  • Customers say it has a gritty/chalky flavor
  • Some users reported protein gave them stomach issues
  • Reports of strong sweetness and bad aftertaste

Bottom Line

KOS is a vegan protein with a lot of positive reviews, but a number of people experienced stomach issues using this protein powder.

KOS Organic Plant Protein, a non-GMO and certified organic protein powder, offers unique features compared to Plant+. Although both are vegan-friendly, here’s how KOS stands out:

  • Lower protein per serving: Provides 20 grams per serving, meeting the minimum standard of what we look for in protein powders, compared to Plant+’s 25 grams.
  • Multi-protein blend: Includes pea, chia seed, flax seed, pumpkin seed, and quinoa proteins.
  • Added nutrition: Offers a variety of digestive enzymes, superfoods, vitamins, and minerals.
  • Affordability: Costs about $1.00 less per serving than Legion Plant+.
  • Meal replacement suitability: With higher amounts of carbohydrates, fats, and dietary fiber, KOS is more suitable for those seeking a meal replacement protein powder.
  • Unflavored option: If you prefer adding protein to drinks or foods without changing the taste.

Legion Plant+: FAQs

Is Legion protein powder clean?

Legion Whey+ protein powder is one of the best clean protein powders due to its minimal and natural ingredients list. We also consider Legion’s other protein powders, like Plant+ and Casein+, clean because of their high-quality formulations without added sugars, artificial sweeteners, and preservatives.

What are the downsides of plant protein powder?

Plant-based protein powder benefits mostly outweigh the risks, especially when avoiding known allergens, selecting third-party tested products, and complementing a balanced diet. However, we recommend reviewing the amino acid profile or consulting a nutrition expert, as some powders may lack some essential amino acids necessary to build muscle, enhance recovery, and support overall health.

Can you eat plant protein everyday?

Although consuming plant protein daily is generally safe, vary plant protein sources to ensure the intake of all essential amino acids and other nutrients the body needs to function optimally. For personalized dietary advice, consult a nutrition expert.

Is plant protein inflammatory?

If managing a soy or plant protein allergy, Celiac disease, or similar condition, consuming the food trigger may cause inflammation. However, without dietary restrictions, recent studies involving aging individuals3 and adults with chronic kidney disease4 suggest that plant proteins may reduce inflammation. A 2020 meta-analysis5 supports that plant-based diets lead to lower levels of C-reactive protein (CRP), an inflammation marker, compared to omnivorous diets.
