Premier Protein vs Muscle Milk vs Nutranelle: Three Protein Powders, Three Different Jobs

Muscle Milk packs 270 calories and 8g of fat into a serving; Premier Protein packs 150 calories and 2g; Nutranelle packs 120 calories and 2g from a completely different protein source. These aren't minor formulation differences - they're three products built for three different jobs.

Our data-driven analysis of product nutritional information and thousands of reviews across these products helps you find the optimal option for you.

The quick answer

• Nutranelle - the only one with a functional nutrition layer (digestive enzymes, greens, antioxidants) built into the formula, and the best value per gram of protein of the three at $0.053/g.
• Premier Protein - the leanest option (150 calories, 2g fat) from a clean isolate-first whey formula, but texture complaints and underfilled containers are real, recurring issues (see the data below).
• Muscle Milk - built to function more like a meal than a supplement (270 calories, 8g fat, 6g fibre), but has the highest texture complaint rate of the three by a wide margin.
• Both Premier Protein and Muscle Milk use artificial sweeteners (Acesulfame Potassium, Sucralose); Nutranelle uses stevia leaf extract only.

The price-per-gram ranking (Nutranelle first, then Muscle Milk, then Premier Protein) surprises most buyers who expect the plant-based option to carry a premium. For Muscle Milk, the more relevant frame is its calorie and fibre contribution: at 270 calories and 6g fibre, it's partially replacing a meal, so comparing its per-serving cost directly to a protein supplement isn't quite apples-to-apples.

For Nutranelle, the functional-stack argument applies too - if you're currently buying a greens powder, a digestive enzyme supplement, and an antioxidant blend separately, the combined cost of those alongside a cheaper protein powder may not be as far from Nutranelle's price as it first looks.

What each one is actually built for

Premier Protein is a lean protein supplement. At 150 calories and 2g of fat, it's designed to top up your daily protein without meaningfully affecting your other macros.

If you're already eating well and need an efficient way to close a protein gap post-workout or at breakfast, this is the most straightforward option in this comparison - it does one job cleanly, without contributing much else.

Muscle Milk is built for a different job entirely. At 270 calories, 8g of fat, and 6g of fibre, it sits closer to a meal-replacement product than a protein supplement - a four-source blend spanning fast-digesting whey and slow-digesting casein, designed to extend amino acid availability over time rather than deliver a single post-workout spike.

If you regularly skip breakfast or need something that genuinely bridges a long gap between meals, that architecture is doing real work for you.

Nutranelle is a different category again: a plant-based protein powder with a functional nutrition stack - organic greens, digestive enzymes, antioxidants, hyaluronic acid, and choline - built into every serving.

At 120 calories and 2g of fat, it's the lightest macro profile of the three; what it trades in protein volume, it makes up for in nutritional breadth per serving.

If you want your protein powder to do more than deliver protein, and you'd rather get all of that in one scoop than buy it separately, this is the only product in this comparison designed for that.

None of these approaches is wrong; the right one is whichever matches how you actually use your protein powder and what else you're eating around it.

What's actually in the scoop

Premier Protein

Premier leads its ingredient list with whey protein isolate, followed by whey protein concentrate. Isolate is the more processed, higher-purity form of whey: lower in fat, lower in lactose, and higher in protein concentration per gram than concentrate.

Leading with isolate means the cleaner input comes first, at higher volume. For a full breakdown of how isolate and concentrate actually differ, see our dedicated comparison of whey protein concentrate, isolate, and hydrolysate.

Beyond the protein, the ingredient list is short: soluble corn fiber, sunflower lecithin, natural and artificial flavors, acesulfame potassium, sucralose, xanthan gum, salt.

No maltodextrin, no carrageenan - a shorter supporting cast than most mainstream protein powders at this price point, with the two artificial sweeteners as the main thing to weigh.

Muscle Milk

Muscle Milk leads with whey protein concentrate before moving through milk protein isolate, calcium caseinate, and sodium caseinate - a four-source blend covering both fast-digesting whey and slow-digesting casein, consistent with its sustained-energy positioning.

The 8g of fat comes primarily from a non-dairy creamer system (sunflower oil, canola oil, medium chain triglycerides), which explains both the richness and the satiety. The 6g of fibre comes from isomalto-oligosaccharides (a prebiotic fibre) and organic oat fiber.

Maltodextrin appears twice in the ingredient list - once standalone, once within the creamer sub-blend. That's not unusual in complex formulations, but it's worth knowing: maltodextrin carries a glycemic index in the 105–110 range, higher than table sugar, which matters if you're monitoring processed carbohydrate inputs or blood sugar response specifically.

Muscle Milk also carries NSF Certified for Sport status, meaning it's been screened against substances banned by major athletic organizations and verified to match its label claims - meaningful if you're subject to drug testing.

Nutranelle

Nutranelle's formulation starts from a different premise, and it shows in what's absent as much as what's present: no maltodextrin, no artificial flavors, no artificial sweeteners.

The protein comes from four plant sources - fava bean, mung bean, pea, and rice - combined specifically because each source covers different essential amino acids, so blending them closes gaps no single plant protein fills alone. A 2018 laboratory analysis measuring the leucine content of commercial whey, pea, rice, soy, hemp, and egg protein isolates is part of the research behind why this kind of blending approach works.

Three named functional blends appear in every serving. The digestive enzyme blend (protease, amylase, lactase, lipase) supports breakdown of protein, carbohydrates, dairy, and fat.

Lactase is worth a specific note here: it's an enzyme your small intestine normally produces to break lactose down into glucose and galactose, the simpler sugars your body can actually absorb - not a dairy ingredient. Including it in the enzyme blend supplements that digestive process for lactose you might get from other foods; it isn't a sign the product itself contains any.

The Organic Greens Balance Alkalizing Blend covers nine greens and plant sources including spirulina, chlorella, and kale. The Betta Berries Antioxidant Blend draws from ten fruit sources including pomegranate, goji, acai, and acerola. Hyaluronic acid and choline complete the functional layer.

Astragalus root extract appears in the Organic Greens Blend. It's an adaptogenic herb with a long history of use in traditional Chinese medicine. NCCIH's overview of astragalus's traditional uses and the current gaps in clinical research are worth a look if this is new to you.

Sweeteners

Premier Protein and Muscle Milk both use acesulfame potassium and sucralose. FDA's regulatory overview covering acesulfame potassium, sucralose, and other approved sweeteners confirms both are calorie-free, synthetic, and FDA-approved. Examine's deep-dive on whether sucralose affects appetite and energy balance is worth reading if you want the fuller research picture on sucralose specifically.

Nutranelle uses stevia leaf extract as its only sweetener. Examine's research breakdown on stevia's safety profile and studied effects covers the plant-derived alternative in more depth.

What the review data actually shows

We extracted insights from Amazon's review data for Premier Protein and Muscle Milk: whether reviewers mention aftertaste, digestive issues, and texture or mixing problems, and what the most common complaints are among lower-rated reviews.

Texture is the clearest differentiator. 57% of Muscle Milk's reviews that mention texture are negative - more than double Premier's 28% - with reviewers describing it as chalky, cakey, or sandy.

Blendability and digestibility complaint rates are much closer between the two: Premier sits slightly higher on both (25% blendability, 26% digestibility) than Muscle Milk (21% blendability, 17% digestibility), though neither gap is large enough to call decisive.

On aftertaste specifically: Premier's data didn't yield a single clean percentage - reviewer sentiment is genuinely mixed, with several describing no aftertaste at all and others describing a strong, lingering one.

Where reviewers name a cause, they point to the artificial sweeteners. Muscle Milk's aftertaste complaint affects roughly 1 in 10 negative reviewers specifically, within a broader 26% negative taste sentiment overall; reviewers who mention it also point to the artificial sweeteners as the source.

The deeper science

Is plant-based protein as effective as whey for muscle building?

Single-source plant proteins generally score lower than whey on protein-quality measures like DIAAS, which is exactly why blended formulas exist. Well-formulated multi-source blend, consumed in adequate total amounts, perform as effectively as whey protein.

 A 2020 data synthesis pooling DIAAS estimates across whey, soy, pea, rice, hemp, and egg protein shows the gap clearly for single sources.

But the training-outcome evidence is more encouraging than the lab scores alone suggest. A 2024 trial found a pea-rice-canola blend matched whey for post-workout muscle protein synthesis, even though whey produced higher blood amino acid levels in the same study - acute amino acid exposure and actual muscle synthesis didn't move together.

A 2018 meta-analysis of nine resistance-training studies found no strength or lean-mass difference between soy and animal protein.

Frequently asked questions

Is whey protein isolate better than whey protein concentrate?

Isolate is more processed, producing a higher protein concentration per gram with less fat and lactose; concentrate retains more naturally occurring compounds and is less processed. Neither is universally better - see our full comparison of whey isolate vs concentrate for the complete picture.

How many calories should a protein powder have per serving?

It depends on the role it plays in your day. Supplementing an otherwise complete diet, 120-150 calories makes sense; replacing a meal or covering a bigger nutritional gap, a higher-calorie option like Muscle Milk fits better. Calories here are a design signal, not a quality signal.

Is plant-based protein as effective as whey for muscle building?

Single-source plant proteins score lower on paper, but well-formulated multi-source blends close most of that gap in practice - see the deeper science section above for the full research picture.

What does NSF Certified for Sport mean?

It screens a product against substances banned by major athletic organizations and verifies label claims match contents. Of the three products here, only Muscle Milk carries it.

Are artificial sweeteners in protein powder safe?

Acesulfame potassium and sucralose are both FDA-approved with long regulatory histories. Individual sensitivity varies, which lines up with the aftertaste complaints some reviewers report for both Premier Protein and Muscle Milk.

Can I use protein powder as a meal replacement?

Muscle Milk's calorie, fat, and fibre profile functions reasonably well as a meal bridge. Premier Protein and Nutranelle are built as supplements rather than meal replacements - they add protein efficiently but don't carry the calorie density or macro breadth to replace a full meal.

Next Steps

If you want plant-based protein with no artificial sweeteners and a functional nutrition layer built in rather than bought separately, Nutranelle's plant protein is the only product in this comparison designed around that - and at $0.053 per gram of protein, it's also the best value of the three.
