“I’m impressed with the taste and solubility... I’m especially happy that it just received one of the lowest 3rd party tested lead levels, a common risk among protein powders and other supplements."

Julie A (Verified Customer)

“Great flavor, taste, and texture. I will definitely buy again—no artificial aftertaste, and I trust the quality. It’s hard to find a protein with such clean ingredients.”

Brittany S (Verified Customer)

High quality grass-fed whey, optimized for max absorption + easy digestion.

Made with only the essentials—no fillers, gums, or artificial sweeteners—our whey isolate meets The Momentous Standard™ in formula cleanliness, efficacy, and testing. It’s essential for everyone, every day.

Momentous Whey Protein Isolate delivers 20g of grass-fed protein per serving to support muscle growth, recovery, and daily wellness. Sourced from European dairy farms held to rigorous standards, and cold-processed to preserve its amino acid profile, it’s designed for maximum absorption and minimal GI discomfort. Enhanced with ProHydrolase® enzymes and NSF Certified for Sport®, this clean, high-performance formula is trusted by elite athletes and everyday high-performers.

  • Supports lean muscle mass and strength
  • Accelerates recovery when taken post-exercise
  • Promotes immune health and overall well-being
  • With ProHydrolase® for superior absorption and easy digestion
  • Free from artificial ingredients, sweeteners, and fillers
Momentous Whey Protein Isolate is a high-quality, grass-fed whey protein designed for optimal performance, recovery, and daily muscle maintenance. Each serving delivers 20g of complete protein sourced from European dairy farms held to rigorous standards—meaning no hormones, steroids, or rBST. Ours is superior in that it’s cold-processed and micro-filtered, preserving the integrity of its amino acid profile while minimizing sugar, fat, and lactose.

What sets our formula apart is the inclusion of ProHydrolase®, a clinically researched enzyme that enhances protein breakdown and amino acid uptake. This not only improves digestion and reduces the risk of GI discomfort, but also ensures that your body efficiently absorbs and utilizes the protein for maximum results.

Whey isolate is known for its fast absorption—ideal for the post-workout window, when your muscles are most receptive to nutrients. It contains high levels of leucine, a key amino acid that directly stimulates muscle protein synthesis, making it a powerful tool for strength development and recovery.
  • 1 scoop with 10-12 fluid ounces of preferred liquid, as needed, to reach optimal daily protein intake.
  • The latest research suggests consuming 0.8 to 1.2 grams of protein per pound of body weight daily, depending on your fitness goals and activity level.

Part of The Momentous Three, along with Creatine and Omega-3, as a daily essential for foundational health.
  • Chocolate: grass-fed whey protein isolate, ProHydrolase®, natural flavors, cocoa, salt, monk fruit extract, stevia
  • Vanilla: grass-fed whey protein isolate, ProHydrolase®, natural flavors, salt, monk fruit extract, stevia
  • Unflavored: grass-fed whey protein isolate, ProHydrolase®
  • Strawberry: grass-fed whey protein isolate, ProHydrolase®, natural strawberry flavor, Reb M*, beet root/carrot juice powder (for color)

ProHydrolase® is a clinically researched enzyme that enhances protein breakdown and amino acid uptake.

*Reb M is a natural, plant-based sweetener with zero glycemic response or aftertaste. Our Reb M is made from fermated sources and is 250× sweeter than sugar without bloating, 2.5× sweeter than monk fruit, and made sustainably with less land, water, and crop rotation.
Use daily, as needed to hit your individual protein goals. A general guideline many experts suggest is 0.8 to 1.2 grams of protein per pound of body weight (about 1.6 to 2.7 grams per kilogram) each day. Competitive athletes, people with intense training schedules, or those aiming to build significant muscle may benefit from the higher end of that range

Estimated 4-6 weeks of supplementation for noticeable improvements in strength and performance, with consistent intake and resistance training. Long-term benefits are best achieved with consistent daily use.

Results vary depending on a host of individual factors including diet and lifestyle, but may include increased strength and stamina, reduced recovery time, and improved overall wellbeing

Frequently Asked Questions

Momentous Whey Protein Isolate is a whey protein supplement sourced from European dairy farms that follow rigorous standards for animal welfare and product quality. The cows are pasture-raised, grass-fed, and not treated with hormones such as rBST.

This sourcing helps ensure a cleaner, higher-quality protein with lower contaminants and better digestibility, supporting muscle recovery and daily protein intake.

Whey Protein Isolate is a more highly filtered form of whey protein than conventional whey or whey concentrate. This additional filtration removes more fat and lactose, resulting in a product that is over 90% protein, lower in carbohydrates and fats, and easier to digest.

Momentous Whey Protein Isolate is sourced from grass-fed cows, contributing to a cleaner protein source and more sustainable dairy practices.

Momentous Grass-Fed Whey Protein Isolate is a dairy-based protein supplement and is not suitable for a vegan diet. However, it can fit into several specialty diets:

  • Vegetarian: Acceptable for those who include dairy in their diet.
  • Gluten-Free: Made without gluten-containing ingredients and tested for purity.
  • Keto and Low Carb: Naturally low in carbohydrates.
  • Lactose Intolerance: As an isolate, most lactose is removed, and added ProHydrolase® enzyme supports digestion. It is not guaranteed to be completely lactose-free, so individuals with severe intolerance should consult a healthcare professional.

Daily protein needs vary based on activity level, body composition goals, and overall diet. Many experts suggest a general range of 0.8 to 1.2 grams of protein per pound of body weight per day, depending on activity level.

Whey protein can be a convenient way to help meet daily protein needs, especially for athletes or individuals with higher training demands. For personalized guidance, consult a qualified nutrition professional.

Yes, all of our products are third-party tested. But that’s not enough for us. That's why we created The Momentous Standard®: a higher bar for science, sourcing, and verification, backed by independent proof you can trust.

Every finished batch of Whey Protein Isolate is certified through NSF Certified for Sport®, a respected independent program that verifies label accuracy and screens for hundreds of banned substances. If a batch fails to meet these independent standards, it does not ship. We also take transparency a step further by publishing third-party test results via Light Labs on individual product pages and making Certificates of Analysis (COAs) available for every batch.

We earn trust the hard way, by proving quality at every step, on every batch, with no shortcuts.

Whey Protein Isolate is generally easier to digest than whey concentrates because most of the lactose is removed during processing. Added digestive enzymes further support protein breakdown and absorption. Individuals with severe lactose intolerance should consult a healthcare professional before use.

Whey protein can be used by a wide range of individuals looking to support muscle recovery, performance, or daily protein intake.

Whey protein is commonly used by:

  • Athletes and active individuals supporting muscle repair and recovery
  • Endurance athletes with higher ongoing protein needs
  • Strength trainers aiming to build or maintain lean muscle mass
  • Individuals with busy schedules or limited access to whole-food protein sources

Whey protein is best used as a supplement to a balanced diet and regular training routine to help meet daily protein needs.

Reviews Summary
Customers say this protein powder mixes well with water, milk, and smoothies without clumping. Many appreciate the clean taste and smooth texture, noting it doesn't have the chalky quality of other protein powders. The vanilla and chocolate flavors receive praise for being delicious and not overly sweet, though some find certain flavors too sweet. Users enjoy adding it to coffee, yogurt, and baked goods. Many reviews mention it's gentle on the stomach and doesn't cause digestive issues. The unflavored version is particularly valued for its versatility. Some customers note the price is high but appreciate the quality ingredients.
