With so many supplements on the market, finding the right protein powder for you can be challenging, especially if you’re not sure where to start.

Gainful is an innovative service that creates a protein powder blend formulated specifically for your needs.

It’s particularly popular among consumers looking to increase their protein intake because it’s simple, convenient, and completely customizable.

This article reviews Gainful, including how it works and who should try it.

Gainful is a subscription service that provides protein powder supplements specifically tailored to fit your needs.

When signing up, it prompts you to take a short quiz, which asks about your height, weight, age, gender, activity level, diet, lifestyle, and health goals.

Gainful then uses this information to suggest a personalized blend that’s formulated just for you.

Your custom protein powder contains between 14–28 servings, depending on how many scoops you use, and ships automatically every 3 weeks with a subscription.

You can easily change your blend at any time and pause, cancel, or change the frequency of your subscription directly on their website.

Most personalized protein powders contain a blend of protein sources, including whey, whey concentrate, whey isolate, micellar casein, organic brown rice protein, and organic pea protein.

Because the protein powders are delivered unflavored, you can use a Gainful Flavor Boost to customize your protein shake.

When creating your blend, you’re able to select from a variety of Flavor Boosts, including:

  • Rich Cocoa
  • Cookies & Cream
  • Caffè Mocha
  • Madagascar Vanilla
  • Strawberry Cream
  • Chocolate Peanut Butter

You can also choose whether you would like to purchase any optional add-ons for an extra fee, such as their pre-workout powder or the Gainful Blender Bottle.

Gainful uses only high quality ingredients in their products and sources ingredients from manufacturers that provide a Certificate of Analysis (CoA), which is a document that contains detailed information about the quality and safety of ingredients.

All Gainful protein powders are unsweetened, unflavored, and made without any artificial coloring, fillers, thickening agents, or preservatives.

Plant-based protein ingredients are also all vegan, organic, and free of genetically modified organisms (GMOs).

The Flavor Boosts are made using natural flavors and are sweetened with organic stevia leaf extract or organic monk fruit extract.

They also contain maltodextrin, which can help muscle building but may affect blood sugar levels (1, 2).

All Gainful protein powders are unflavored, which allows you to mix in your choice of Flavor Boost for a custom protein shake tailored to your taste buds.

However, if you would prefer, you can also sweeten your protein powder at home using your favorite ingredients.

Honey, berries, bananas, maple syrup, cocoa powder, peanut butter, vanilla, or cinnamon are all excellent options to add a hearty dose of flavor to your drink.

Gainful protein powders can be customized to fit your needs and can be easily incorporated into a variety of dietary patterns.

For example, plant-based protein powders made from organic rice protein and organic pea protein are available for vegans and vegetarians.

There are also low carb varieties for those following a ketogenic diet, which contain MCT oil for an added dose of healthy fats.

When completing the quiz, you can also select other dietary restrictions or allergies, including:

  • lactose intolerance
  • gluten allergy
  • soy allergy
  • dairy/whey allergy
  • peanut allergy

Keep in mind that although Gainful protein powder blends are free of allergens like soy, wheat, nuts, shellfish, fish, and eggs, they’re manufactured in a facility that processes these ingredients and may be unsuitable for those with severe food allergies.

Some research suggests that increasing your protein intake may aid weight loss (3).

In fact, according to one large review of 24 studies, high protein diets were more effective at reducing body weight and fat mass than low fat, standard protein diets (4).

Protein may also affect levels of several hormones that influence hunger and appetite to enhance feelings of fullness, including ghrelin, glucagon-like peptide 1 (GLP-1), and peptide YY (5).

What’s more, some studies show that protein may help maintain lean body mass after weight loss and boost your metabolism to increase the number of calories that your body burns during the day (6, 7).

These benefits come from protein in general, so eating foods rich in protein is just as beneficial as adding protein powders to your diet.

Gainful protein powder costs $39 for 14–28 servings and also includes 14 single-serve Flavor Boosts of your choice.

Your subscription also includes unlimited access to a registered dietitian, whom you can contact with questions using their website.

There are several other add-ons that you can order for an extra fee, including the Gainful Pre-Workout powder, which costs $19 for 14 servings.

The Gainful BlenderBottle can also be purchased for just $5.

Besides Gainful, there are several other similar services that also offer personalized protein powders.

True Nutrition, for example, allows you to create your own protein powder blend by selecting from a variety of protein sources, carbs, fats, and flavorings.

However, while this may be more cost-effective, it can also be challenging for those who aren’t sure which ingredients are right for them.

Care/of also offers customized protein powders based on your needs, along with other supplements like vitamins, minerals, herbs, and probiotics.

Alternatively, once you know what you’re looking for, you can simply purchase protein powders online or from your favorite health store instead.

Not only are there plenty of protein powders available with many flavors and ingredients, but it can also be a much more budget-friendly option in the long run.

Gainful is a great option for those who are interested in adding protein powder to their routine but are unsure where to start.

With its flexible subscription plan, it’s also ideal for people who prefer to have their protein powder shipped directly to them, without the hassle of reordering every few weeks.

Because there are so many options available, it may also be a good choice for those with specific dietary restrictions who have difficulty finding a product that fits their needs.

However, it’s pricier than other protein powders and may not be the best option for long-term use for those on a tight budget.

Gainful is a subscription service that provides personalized protein powder blends based on your specific needs.

After completing a quick and easy quiz with information on your diet, lifestyle, and health goals, Gainful takes the guesswork out of shopping for supplements by creating a formula just for you.

With many options and ingredients available, Gainful protein powders can fit into nearly any diet and can be an easy and delicious way to ramp up your protein intake.
