Organic protein powders have become increasingly popular lately. By combining three plant-based proteins, Orgain Organic Protein Powder ranks as our best flavorless protein powder that is organically sourced. Orgain’s protein is made up of the following:

  • Brown Rice
  • Organic pea
  • Chia

Brown rice is an incomplete protein, lacking in some essential amino acids, particularly lysine. Nevertheless, it represents an excellent source of fiber, complex carbohydrates, and several essential minerals, including magnesium, phosphorus, selenium, and manganese. The B vitamins thiamine, niacin, and vitamin B6 are also present.

Peas are a fantastic source of plant-based protein. Organic pea protein includes branched-chain amino acids (BCAAs), crucial for muscle growth, repair, and general health. Pea protein has all nine essential amino acids. However, while mixing pea protein with other plant protein sources can help produce a balanced amino acid profile, pea protein is relatively low in the amino acid methionine.

Chia is a tiny seed from the Salvia hispanica plant that is used to make vegan protein powder. Chia seeds are also a good source of omega-3 fatty acids, especially alpha-linolenic acid (ALA). Combining these three protein sources represents a complete source with many health benefits.

You get a total of 21 grams of vegan protein with this powder. You also get 15 grams of carbs (comparatively high) and 1 gram of sugar.

  • +Vegan protein source
  • +Combines organic pea, brown rice, and chia protein
  • +21 grams of sugar per serving

3. Best Vegan Unflavored Protein Powder: Naked Pea Protein

best unflavored protein powder for weight loss

Yellow split peas are the sole protein source for Naked Pea Protein. It provides 27 grams per serving for a calorie cost of just 120 calories. Pea protein is not officially a complete protein because it is slightly down on methionine+cysteine.

However, it still represents an excellent protein source, containing the other eight essential amino acids in higher than minimum levels to be considered complete. In addition, it’s a good source of branched-chain amino acids (BCAAs), crucial for muscle building and recovery, as minerals like iron.

Yellow split peas are the only ingredient in this product. It is free of additives, as well as being soy and gluten-free. With just two grams of carbs and the same sugar count, this is a good choice for people trying to lose weight.

MyProtein Slow-Release Casein Protein Powder delivers amino acids over an extended period to enhance muscle growth and recovery. That’s because the micellar casein used in this product has a slow digestion and absorption rate.

Unlike fast-digesting protein sources like whey protein, micellar casein produces a gel-like structure in the stomach. This facilitates a slow release of amino acids over a long period. The delayed release makes it the perfect option for overnight use or extended fasting times because it can assist in offering a maintained protein supply to muscles.

You get 23 grams of casein protein in every MyProtein Slow-Release Casein Protein Powder serving. Micellar casein is the only ingredient in this product, so you have no worries about additives or flavorings. A 33-serving container costs $1.81 per serving. That puts it at the expensive end of the market.

  • +Slow release protein

Naked Rice from Naked Nutrition contains nothing but organic sprouted brown rice protein. A hexane-free extraction process produces a pure vegan plant-based protein powder from the source. The hexane-free extraction procedure attempts to generate protein powders free from residual solvents and potential impurities using water-based extraction techniques instead of hexane.

This method is regarded as safer for human consumption and more environmentally friendly. In addition, it makes it possible to create high-grade protein powders that maintain the original plant-based protein source’s nutritional qualities.

Every serving of Naked Rice provides 25 grams of protein, 120 calories, 4 grams of carbs, and zero sugar. This additive, gluten, and soy-free powder mixes well but may leave some gritty residue at the bottom of the cup. Every batch is 3rd party tested to ensure that only the highest quality product hits the shelves.

Why choose an unflavored protein powder?

Opting for an unflavored protein powder will give you a shake that doesn’t taste as good. But, for many people, that negative is far outweighed by the benefits of unflavored protein powder options. Here’s an overview of the main reasons that people choose to go for unflavored protein powders.

1. Fewer filler ingredients

Unflavored protein powders generally have fewer artificial colors or sweeteners. To get an appreciation for what a big deal that is, consider just one of the popular artificial colors used in the protein powder market; Yellow #5. This ingredient has been shown to potentially cause cancer and other side effects.¹ You’ll find Yellow #5 in banana flavored, lemon, and birthday cake protein powders.

2. Versatility

When you purchase an unflavored protein powder, you actually have more freedom to flavor your shake. You can do so by adding fruit or other healthy ingredients like yogurt.

But when the shake is already flavored, you’ll end up with a strange blend of flavors that will probably not appeal to your taste buds. In addition, you can add unflavored protein powder to all sorts of recipes without ruining the end taste.

3. Allergies

Flavored protein powders may contain additives, artificial sweeteners, preservatives, and potential allergies, including dairy, soy, gluten, or nuts.

In addition, some people may develop allergies or sensitivities to certain chemicals used to flavor the powder. You can avoid potential allergens and have more control over the ingredients you put into your body by choosing unflavored protein powders.

What to look for when buying an unflavored protein powder:

Knowing what to look for is the key to getting an unflavored protein powder to help you achieve your goals while promoting your overall well-being. Here are seven key considerations:

1. Protein Type

Different protein types have distinct qualities and advantages. Here’s an overview of the main types of protein used in powders:

  • Whey Protein: Made from milk, whey protein has a high biological value and an excellent amino acid composition, making it one of the most widely used protein sources. It is quickly absorbed and digested, which makes it the perfect option for post-workout recovery. Unless someone has a severe lactose sensitivity or allergy to dairy, most people tolerate whey protein powders well.
  • Casein Protein: Casein protein, like whey protein, comes from milk. Casein, though, is a slower-digesting protein that offers a steady supply of amino acids. That makes it great as a longer-lasting source of protein, especially if taken before bed or during fasting times.
  • Plant-Based Protein: Plant-based protein powders are becoming increasingly popular, especially with vegetarians, vegans, and people allergic to dairy. Pea protein powder, soy protein powder, hemp protein powder, and rice protein powder are familiar plant-based protein sources. Each source of plant-based protein has a different amino acid composition and degree of digestion. Combined, plant-based proteins may offer a complete amino acid profile, ensuring you get all the necessary amino acids.
  • Other Protein Types: Other protein kinds, such as egg white protein, cow protein, and collagen protein, are marketed in addition to whey, casein, and plant-based proteins. These protein powders could provide certain advantages or satisfy people’s dietary needs or preferences. For instance, collagen protein is well known for helping to maintain healthy skin, hair, and joints.

2. Macronutrient Content

Unflavored protein powders typically contain more protein and fewer carbohydrates than their flavored counterparts. That’s a good thing for those who want to lose body fat. However, if you’re after a post-workout protein powder, you’ll want a decent amount of carbs to replace the glycogen you’ve expended during your workout.

Here’s an overview of the typical macronutrient makeup of unflavored protein:

Protein: Naturally, protein is the primary macronutrient in protein powder. Choose a protein powder with a protein composition aligned with your goals, such as muscle growth, post-workout recovery, or general protein replenishment.

Most protein powders have a serving size of 15 to 30 grams of protein.

Carbohydrates: The carb count in unflavored protein powders varies depending on the protein source and any added additives. While some protein powders have a low carbohydrate content, others could incorporate sweeteners or fillers that raise the carbohydrate content.

Choose protein powders with reduced carbohydrate content if you’re on a low-carb or ketogenic diet or want to reduce your carbohydrate intake.

Fats: Most protein powders have a very low-fat content, especially if they are isolates rather than concentrates. Check the protein powder’s fat level to ensure it fits your goals if you watch your fat intake or adhere to a particular diet.

3. Other ingredients

Here are some key extra ingredients that will boost the effectiveness of your unflavored protein powder:

Glutamine: Glutamine is a conditionally necessary amino acid that is essential for muscle growth and recovery. Glutamine supplements may promote immunological function, lessen muscle pain, and support muscle growth.

Branched-Chain Amino Acids (BCAAs): Leucine, isoleucine, and valine are necessary amino acids recognized to promote muscle protein synthesis and minimize muscle protein degradation. Some unflavored protein powders may add BCAAs for a balanced amino acid profile. Some people prefer to add their own BCAA supplements for the their preferred ratio.

Creatine: Creatine is a naturally occurring substance mainly found in muscle cells throughout the body. It is essential for producing energy during intense exercise. Some unflavored protein powders add it helps with muscle strength and athletic performance. You also may want to consider buying a separate creatine supplement to get the most out of this ingredient.

Digestive Enzymes: Some powders include additional digestive enzymes like lipases, amylases, or proteases. These enzymes support the digestion and breakdown of several food types, including proteins, carbs, and lipids. If you have certain dietary sensitivities, a digestive enzyme supplement may be beneficial to have.

4. Mixability

The best tasteless protein powder will blend smoothly and efficiently with liquids to produce a smoothie that is convenient to blend and more pleasant to drink. Powders with poor mixability will likely produce clumps, a gritty texture, or a chalky feel.

Another aspect to consider is whether the protein powder causes any silt or residue in the cup. Choose a pure protein powder that mixes up with little to no residue.

Choosing a protein powder that mixes well with simply a shaker bottle may be more convenient if you’re looking for something you can quickly mix on the move.

How easily a protein powder dissolves in a liquid is called solubility. Good solubility allows protein powders to dissolve completely without leaving clumps or undissolved particles behind.

5. Versatility

Fine, readily dissolved protein powders are more versatile since they can be used in various recipes without changing the dish’s overall texture. Unflavored powders can be an excellent complement to your baking and cooking projects.

In addition, they can be added to recipes to increase the protein content of foods like pancakes, muffins, energy bars, cookies, and more.

If you intend to use the protein powder in baked items that call for baking or cooking at higher temperatures, pay attention to the protein powder’s heat stability.

Some protein powders might denature or lose their nutritious value when exposed to intense heat. Select a protein powder designated as being heat-stable or appropriate for baking.

6. Price

Your value-for-money determination should consider the price per serving, the protein content, extra ingredients, and mixability. You should expect to pay between $1-$2.00 per serving.

7. Reviews

You need to check online reviews to get the best protein powder with no taste. Reviews from verified purchasers can help determine the unflavored protein powder’s quality and purity.

Mixability and texture are frequently mentioned in reviews. This can help determine whether the unflavored powder dissolves smoothly in liquids without clumping or having a gritty texture. Pay attention to reviews that mention how well the protein powder mixes and the mechanism used (shaking bottle, blender, etc.).

User evaluations can shed light on the unflavored protein powder’s digestive tolerance. Some people might share their experiences with bloating, gas, or other digestive problems.

If you have a sensitive stomach or certain dietary restrictions, look for reviews discussing how the powder affects the stomach.

Take into account the following when checking user reviews:

  • To ensure credibility, look for reviews from verified customers.
  • Read several reviews to gain a variety of viewpoints and experiences.
  • Take into account both favorable and unfavorable comments to get a well-rounded viewpoint.
  • Keep an eye out for reviews that speak to certain factors that are significant to you, such as quality, mixability, or digestive tolerance.
  • Recognize that as preferences differ from person to person, not all reviews will likely match your own.
