PVL ISO CLEAAR Review: Is This the Future of Protein?

PVL ISO CLEAAR protein review featuring Blue Slushie, Summer Peach and Grape Refresher flavours in an athletic gym setting.

With 20 grams of protein and amino acids, zero sugar, 80 calories, and the first commercial use of LEUVATE+™, PVL ISO CLEAAR takes a different approach to protein supplementation—one built around protein efficiency rather than simply adding more protein.

PVL Combines Clear Protein With LEUVATE+ Technology to Rethink the Traditional Protein Shake

For decades, protein powder has largely been a numbers game. More grams of protein per scoop usually meant a more impressive label.

PVL’s new ISO CLEAAR challenges that thinking.

Instead of building another traditional 25- or 30-gram whey shake, ISO CLEAAR combines whole protein with free-form amino acids to provide 20 grams of protein and aminos with only 80 calories and zero sugar.

At the centre of the formula is LEUVATE+™, a leucine-enriched essential amino acid system built around a concept Muscle Insider recently explored in depth: protein efficiency.

And with the price of whey protein climbing dramatically, while athletes and everyday consumers increasingly look for ways to consume adequate protein without continually adding more calories or another heavy shake, the timing couldn’t be much better.

What Is PVL ISO CLEAAR?

Despite the name, ISO CLEAAR isn’t a traditional whey protein isolate.

It’s a dairy-free, clear protein drink designed to have a lighter, juice-like consistency rather than the thick and creamy texture associated with most protein shakes.

Each serving provides 20 grams of protein and amino acids, divided into 12 grams of whole protein and 8 grams of free-form amino acids. The whole-protein portion combines beef protein isolate, fermented pea protein isolate and fava protein, while the amino-acid component includes LEUVATE+ and additional conditionally essential amino acids.

The result is a formula where each serving provides 80 calories, with zero grams of sugar and zero grams of fat.

ISO CLEAAR is currently available in Blue Slushie, Summer Peach and Grape Refresher flavours, with 650-gram and 1.81-kilogram (4-pound) sizes available.

But there’s considerably more happening here than simply creating a lighter, juice-style protein drink.

The Ingredient That Makes ISO CLEAAR Different: LEUVATE+

Muscle Insider recently took a deeper look at LEUVATE+ following our conversation with researcher Dr. Daniel Traylor and supplement-industry veteran Jim McMahon at the 2026 Arnold Sports Festival.

LEUVATE+ combines all nine essential amino acids with an emphasis on leucine, one of the primary nutritional signals involved in initiating muscle protein synthesis (MPS).

Think of leucine as helping give muscle the signal to start building, but a signal alone isn’t enough. Muscle protein synthesis also requires the other essential amino acids that provide the building materials necessary to construct new proteins.

That’s why the distinction between LEUVATE+ and simply adding extra leucine or BCAAs matters.

There’s another difference: speed.

Whole proteins first have to be digested into their constituent amino acids. Free-form amino acids don’t require that same digestive breakdown before becoming available for absorption.

ISO CLEAAR attempts to take advantage of both approaches by combining rapidly available free-form amino acids with whole protein that continues through the normal digestive process.

Can Less Protein Really Do More?

This is where the science becomes particularly interesting.

Human research has shown that relatively small servings of leucine-enriched essential amino acids can produce substantial acute muscle protein synthesis responses.

In older women, researchers have found leucine-enriched EAA formulations capable of stimulating MPS responses comparable to considerably larger servings of whey protein under specific experimental conditions. Other research has demonstrated that increasing the leucine concentration of an EAA supplement can increase post-exercise MPS compared with an equivalent amount of EAAs containing less leucine.

That provides meaningful support for the principle behind protein efficiency.

But it doesn’t mean 3 grams of EAAs suddenly replaces someone’s daily protein requirements.

Acute muscle protein synthesis, total daily protein intake and long-term increases in muscle mass are related concepts, but they aren’t interchangeable. Much of this research examines short-term physiological responses under controlled conditions, so more research is needed to determine how these effects translate into long-term differences in muscle growth, strength and body composition.

The takeaway is therefore more nuanced, and arguably more interesting.

LEUVATE+ isn’t about eliminating protein. It’s about potentially generating a stronger anabolic response from a strategically formulated combination of protein and amino acids.

Why Protein Efficiency Matters More Than Ever

There is also an economic reality behind this conversation.

Protein—particularly whey—has become considerably more expensive as growing global demand for high-protein foods and supplements has collided with pressure on whey supplies. That eventually affects everyone from supplement manufacturers to consumers staring at the price tag on a tub of protein.

The traditional solution of simply putting more whey into every serving becomes increasingly expensive in that environment. Protein efficiency offers a different question:

Instead of continually asking how much protein can fit into a scoop, can we formulate that protein more effectively?

There’s no reason to suggest PVL developed ISO CLEAAR simply as a way to avoid expensive whey. The product’s dairy-free, clear-drink format and amino-acid system have their own rationale.

But the economics of protein make the underlying concept particularly relevant in 2026.

More Than LEUVATE+: Breaking Down the Formula

LEUVATE+ may get the headlines, but ISO CLEAAR isn’t simply an amino-acid supplement.

Each serving contains 12 grams of whole protein from beef protein isolate, fermented pea protein isolate and fava protein.

The remaining 8 grams consist of free-form amino acids, including 4,365 milligrams of LEUVATE+ and 3,635 milligrams of conditionally essential amino acids.

The LEUVATE+ portion provides all nine EAAs, including leucine, isoleucine, valine, lysine, threonine, phenylalanine, methionine, histidine and tryptophan.

The added EAA profile helps create a more comprehensive amino-acid formula alongside the blend of beef, pea and fava proteins.

ISO CLEAAR also contains vitamin C, vitamin B6, vitamin B12 and vitamin D3.

Who Is ISO CLEAAR Best For?

The obvious audience is anyone who’s simply tired of drinking traditional protein shakes.

For athletes training in warm conditions, physique competitors deep into contest preparation or anyone who doesn’t want another thick, milkshake-style drink after training, a light juice-style protein drink has obvious appeal.

The 80-calorie serving also makes ISO CLEAAR particularly interesting during calorie-restricted phases when athletes are trying to maximize nutritional value without unnecessarily increasing energy intake.

There’s another emerging audience worth considering: people using GLP-1 medications.

As Jim McMahon discussed during our previous interview, appetite suppression can make consuming adequate calories and protein more difficult for some GLP-1 users. Current nutritional guidance surrounding GLP-1 therapy similarly emphasizes adequate protein intake and resistance training as important considerations during weight loss.

That doesn’t make ISO CLEAAR a treatment for muscle loss, nor has LEUVATE+ been demonstrated to prevent muscle loss specifically in people taking GLP-1 medications.

What ISO CLEAAR does provide is a relatively low-calorie, low-volume and light-drinking way to supplement protein and amino-acid intake when consuming another meal or heavy protein shake may not be appealing.

And importantly, neither protein supplements nor amino acids replace the need for adequate nutrition and resistance training.

Muscle Insider’s Take on PVL ISO CLEAAR

ISO CLEAAR is interesting because PVL hasn’t simply changed the flavour or texture of the traditional protein shake. It has changed the formulation strategy behind it.

Combining whole protein, rapidly available amino acids and LEUVATE+ makes this one of the more scientifically interesting protein launches we’ve seen recently.

The science supporting leucine-enriched essential amino acids and their role in stimulating muscle protein synthesis has been developing for years. LEUVATE+ builds on that established body of research, applying it to a formulation designed to help make protein intake more efficient.

And at a time when protein prices are soaring, consumers are looking for lower-calorie options, and the sports-nutrition industry is being challenged to do more than simply put another scoop of whey into a tub, protein efficiency deserves attention.

For decades, the industry’s answer to better protein supplementation has largely been more protein.

PVL ISO CLEAAR poses a different question:

What if the next evolution isn’t simply consuming more protein, but getting more from the protein we consume?

That may ultimately be the most interesting thing about ISO CLEAAR.
