When Zachary Levi sets out to do something, he makes sure it’s done right. If you’re familiar with the Shazam! star, you probably know that he significantly raised his muscle quotient for the role—and in the process, he became passionate about workouts, nutrition, and health.

Thus, Flow Supplements was born. Disconcerted with the fillers and subpar ingredients found in many workout supplements, Levi decided to create his own. He launched the company in early 2019 after working to create a formula that would be healthy, safe, and vegan-approved.

Let’s take a look at Flow’s protein supplement offering and see what it’s all about.

About Flow Protein Plus/Benefits

Flow’s Protein Plus supplement is designed to assist with muscle-building and workout recovery by improving your “flow”—the flow of your workout, energy, and overall life. Proteins and amino acids work together to curb hunger and provide many nutrients that improve health and well-being.   

Protein Plus Ingredients

Flow Protein Ingredients

As a company, Flow prides itself on using healthy ingredients and being 100% transparent about all of them, which is an excellent way for a company to begin. Evidently, some plant-based protein supplement companies don’t like to disclose the number of protein grams included in their products, so Flow makes all that information readily available.

Their website states that they use no soy, gluten, dairy, or sugar, as well as having natural flavors. Let’s take a look at the ingredient profile.

First off, let’s look at the proteins. All the Protein Plus proteins are organic, vegan-friendly, and plant-based, so that’s good to know from the get-go. No proprietary blends here, no fillers, and full transparency. Flow Protein does not contain whey protein like you’ll find in Ghost Whey and other similar products.

Pea Protein

Of the 19g protein included in one serving of Protein Plus, nearly 15 of those come from pea protein. An excellent choice for vegans, vegetarians, or anyone, pea protein is good for weight loss and muscle-building. It contains 9 essential amino acids and a healthy dose of iron, and it’s also good for the heart. The only potential negative to pea protein is its sodium content, which is where Protein Plus gets a good chunk of its sodium count.

Watermelon Seed Protein

You knew watermelon was good for you, but how about the seeds? As it turns out, watermelon seeds are packed with nutrients. Besides the proteins, they contain both omega-3 and omega-6 fatty acids as well as minerals such as copper, potassium, magnesium, zinc, and iron. The seeds can help with skin and hair, boost energy levels, help control blood sugar, and strengthen the bones. Who knew?

Pumpkin Seed Protein

Pumpkin seeds—or pepitas—you’re probably a little more familiar with. But you may not have known that just one ounce of these white seeds contains 5g of protein, thus making them another good choice for a vegan protein powder. Pumpkin seeds provide lots of health benefits—fiber, healthy fats, minerals, vitamin K, and vitamin B2, to name a few. They’re also loaded with antioxidants and can improve heart health and sleep patterns, among other things.  

Aside from the plant-based protein blend, the most important ingredient is the amino acid blend—a “full clinical dose” of the 9 essential amino acids. These are what help your body the most when training by boosting muscle-building capacity, improving strength, and aiding your body in post-workout recovery.

Further ingredients consist only of organic agave, natural flavors, sea salt, xanthan gum, and sucralose. Aside from the ubiquitous “natural flavors,”—which, as always, could be anything but we have to trust that they’re natural—sucralose is the only questionable element.

Overall, the ingredient profile is 98% positive. If they’d switch the sucralose to stevia (which apparently has been rumored as a possibility, according to one reviewer), it would be 100%. Let’s hope they upgrade!

Does Flow Protein Plus Work? Claims vs. Reality

Flow Protein Claims

Being that Flow is still a pretty new company, they haven’t accrued tons of reviews on their site yet. However, the ones they do have are effectively glowing, so they’re definitely off to a great start. Customers are pretty much in agreement that both Protein Plus flavors taste great, aren’t chalky, don’t upset the stomach—and they boost energy, increase recovery time, and improve stamina with workouts. They’ve mentioned that it’s also great as a breakfast or meal replacement.

Flow as a company doesn’t make a whole lot of claims about their product, but the ones they do make—helping with muscle-building and improving post-workout recovery time—can pretty much be backed up by science in relation to the protein/amino acid ingredient profile. As for individual results, that will take a while to determine, but it’s a fair bet most of the population will see at least some health benefits from Protein Plus.

Who is the Flow Protein Plus Best For?

Flow Protein Plus is ideal for both men and women—anyone who is concerned with getting enough protein and amino acids and recovering properly from workouts. It’s also a great meal replacement for those looking for a quick tummy-filler.

Scientific Studies On Flow Protein Plus


Although a lot of careful thought and planning obviously went into the formulation of Flow Protein Plus, it doesn’t appear that any clinical studies have been done on the product to date. However, enough studies have been done on the main individual ingredients that it’s safe to say they are healthy, natural, and beneficial. In fact, the vegan proteins have specifically been chosen to be safe for those with food allergies, especially to whey and soy.

Where to Buy Flow Protein

Buy Flow Protein

Flow Protein Plus is available for order on their website, (not to be confused with, which is a different company), and on Amazon. A 30-day supply is $69.99 on both sites and comes in two flavors: Brownie Batter and Salted Vanilla Caramel. Yum!

The cost is a negative factor for some, but it’s to be expected with high-quality ingredients (especially mostly organic ones). While it may be a bit of a deterrent, with Protein Plus, it’s a you-get-what-you-pay-for situation. Besides, even if you drink a serving every day, a container will last you a month, which is more than can be said for some supplements. All in all, it’s probably equal to or cheaper than buying a few organic meals per month.


Flow Protein Flavors

Protein Plus is an excellent option for those looking to train and supplement their workouts and lifestyle with a healthy protein powder. Besides providing a high-quality vegan protein supplement, Flow has an active Instagram where they post videos of exercises and workout plans, tips, specials, and Q&A. It’s evident that Flow is committed to building a community of nutrition, fitness, and well-being. Clearly, Zachary Levi has created a great company with quality products, and it can only get better from here.
