Musclesport Clean Whey Naturals: Pure Grass-Fed Protein with Nothing Artificial

Musclesport introduces Clean Whey Naturals with grass-fed whey isolate. No artificial ingredients, just 25g protein with natural flavors and stevia. The market’s cleanest protein is here.

The supplement industry is shifting toward cleaner, more natural formulations, and Musclesport is leading the charge with their newest innovation: Clean Whey Naturals. This ultra-pure protein powder strips away everything unnecessary, leaving only grass-fed whey protein isolate and natural ingredients that health-conscious consumers demand.

Clean Whey: A Natural, Grass-Fed Whey Protein Isolate from Musclesport

While Musclesport’s original Lean Whey has dominated the market with its creative flavors and metabolic-supporting matrix, Clean Whey Naturals takes a different approach – absolute purity. Each scoop delivers 25 grams of premium grass-fed whey protein isolate, processed using advanced cross-flow cold infusion technology to maintain the protein’s natural bioactive components.

What sets Clean Whey Naturals apart isn’t just what’s in it – it’s what isn’t. No artificial sweeteners. No artificial colors. No unnecessary fillers. Just pure, grass-fed whey protein naturally flavored and sweetened with stevia leaf extract (and allulose in the chocolate flavor), making it perfect for athletes and fitness enthusiasts who want the cleanest protein possible.

Musclesport Clean Whey Naturals Ingredients

What powers Clean Whey Naturals? Grass-fed whey protein isolate, of course, but don’t miss the natural flavors and sweeteners discussed below:

• Cross-Flow Cold Infused Ultra Micro-Filtrated Grass Fed Whey Protein Isolate

  At the heart of Clean Whey Naturals is its ultra-pure grass-fed whey protein isolate (WPI), processed using advanced cross-flow microfiltration technology. This premium protein source delivers 25 grams of highly bioavailable protein per serving, with minimal fat and lactose content.

  The cross-flow cold infusion process is crucial for maintaining protein quality. Unlike traditional heat-based filtration methods, this gentle cold processing helps preserve the protein’s natural bioactive compounds and native protein structures.^[1] This results in higher concentrations of important muscle-supporting compounds like:

  

  • Essential amino acids (EAAs)
  • Branched-chain amino acids (BCAAs)
  • Immunoglobulins
  • Lactoferrin
  • Other beneficial whey fractions

  The ultra-microfiltration process also removes nearly all fat and lactose, making Clean Whey Naturals incredibly pure and easier to digest than conventional whey proteins. This extensive filtration results in protein purity exceeding 90%, delivering maximum protein with minimal carbohydrates and fat.^[2]

  Research has shown that whey protein isolate is rapidly digested and absorbed compared to other protein sources, leading to a faster and larger increase in blood amino acid levels.^[3] This rapid absorption makes it particularly effective for supporting muscle protein synthesis both before and after exercise.

  The Quality and Ethics of Pure Grass-Fed Protein

  The grass-fed source of this whey protein reflects Musclesport’s commitment to both quality and ethics. While grass-fed dairy hasn’t been conclusively proven to be nutritionally superior, choosing grass-fed supports more sustainable and humane farming practices where cows are allowed to graze naturally on pasture rather than being confined to feedlots. This ethical sourcing aligns with the values of health-conscious consumers who care not just about what’s in their protein, but where it comes from.

  When combined with resistance training, this premium WPI has been shown to support:^[4]

• Clean Whey’s Natural Flavoring System

  Stevia is a natural, zero-calorie sweetener derived from the leaves of Stevia rebaudiana, a plant native to South America that has been used for centuries as a natural sweetening agent.^[5] What makes stevia particularly valuable in protein powders is not just its sweetness, but its ability to enhance the overall flavor profile while providing potential metabolic benefits.

  Research indicates that stevia doesn’t just replace sugar – it may actually help support healthy blood glucose levels when consumed with carbohydrate-containing meals.^[6] This is especially relevant for athletes and fitness enthusiasts looking to maintain stable energy levels throughout their day.

  One of the historical challenges with stevia has been managing its taste profile – early stevia extracts were known for having a bitter aftertaste. However, modern extraction and purification techniques have dramatically improved stevia’s flavor profile.^[7,8] By carefully selecting specific steviol glycosides and combining them in precise ratios, Musclesport has created a natural sweetening system that delivers clean sweetness without unwanted aftertastes.

  Perhaps most importantly for health-conscious consumers, stevia has an excellent safety profile backed by extensive research. It’s been granted GRAS (Generally Recognized as Safe) status by the FDA and is approved for use as a sweetener by major regulatory bodies worldwide.^[9,10]

  Allulose (Chocolate flavor only)

  In the chocolate flavor, Musclesport pairs stevia with allulose, a naturally-occurring rare sugar that adds to the flavor system’s effectiveness. What makes allulose unique is that it’s a low-calorie sugar (less than 0.4 kcal/g) that actually helps support healthy blood glucose levels.^[11]

  

  Research has shown that when consumed with carbohydrate-containing meals, allulose helps maintain healthy postprandial blood sugar levels without negatively impacting insulin.^[12] This makes it an excellent complement to stevia in Clean Whey’s natural sweetening system.

  Beyond its metabolic benefits, allulose provides a clean, sugar-like taste that helps create the rich chocolate flavor profile that athletes expect from their protein powder – without the sugar content or artificial sweeteners.

• Gum Blend

  Finally, Musclesport knows you have to thicken the protein out. They’ve included a three-gum blend to do so:

  • Gum Acacia: A natural tree sap extract that helps improve protein powder mixability while providing prebiotic fiber benefits
  • Guar Gum: Derived from guar beans, this natural thickener enhances the protein powder’s texture and helps prevent ingredient separation
  • Xanthan Gum: A fermented polysaccharide that creates the smooth, creamy mouthfeel expected from premium protein powders while improving suspension of ingredients[

A New Direction in Clean Protein

The supplement industry is experiencing a dramatic shift as consumers become increasingly conscious of artificial ingredients in their products. This clean-label movement isn’t just a passing trend – it represents a fundamental change in how people approach their nutrition and supplementation.

Market research shows that over 70% of consumers now actively read ingredient labels, and many are specifically avoiding artificial sweeteners and preservatives. This shift stems from growing awareness about how these ingredients might affect long-term health and wellness goals.

Musclesport’s CEO Jason Mancuso (aka The Supp Chef) understands this evolution firsthand. Through his own health journey, he’s experienced significant benefits from reducing artificial sweeteners in his diet. This personal transformation has influenced his approach to product development, leading to the creation of Clean Whey Naturals.

The timing couldn’t be better. With the grass-fed protein market projected to grow significantly over the next five years, Clean Whey Naturals positions Musclesport at the forefront of this movement. By offering a product that’s both clean and delicious, they’re proving that you don’t have to choose between purity and flavor.

Conclusion: The Natural Evolution of Clean Protein

Musclesport’s Clean Whey Naturals represents a perfect balance between purity and performance. While some “natural” proteins sacrifice taste for clean labels, Musclesport has managed to create a product that delivers on both fronts – clean, grass-fed whey protein that actually tastes great. We honestly expect no less from The Supp Chef and Kate.

The attention to detail is clear: from the selection of premium grass-fed whey to the careful processing methods that preserve protein quality, Clean Whey Naturals meets the growing demand for transparent, minimally-processed supplements. Whether you’re an athlete focusing on clean nutrition or simply someone who wants to avoid artificial ingredients, Clean Whey Naturals provides a solution that doesn’t compromise.

By introducing Clean Whey Naturals alongside their popular Lean Whey line, Musclesport shows they understand that different consumers have different needs. While Lean Whey continues to innovate with unique flavors and additional functional ingredients, Clean Whey Naturals serves those seeking the purest protein possible. It’s a smart addition to their lineup that positions Musclesport to serve an even broader range of consumers.
