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.

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
Every Momentous product meets The Momentous Standard®. Signature Spec™ marks the few where we pushed past the industry standard in sourcing, formulation, or testing.
Why Whey Protein Isolate earned it: Protein you can take every day and feel good about. Sourced exclusively from grass-fed cows raised without antibiotics or added hormones, cold-processed to protect the amino acid profile, and formulated with ProHydrolase® enzymes to support absorption and digestive comfort.
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.
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

This is the first protein powder I’ve used so I don’t have another product to compare it with. However, my husband has used several and he liked it so much that I bought him a container. The purity of the ingredients is most important to me. I added a whole milk and my husband uses unsweetened coconut milk. Both are excellent. I would highly recommend this product.

As a 60 year old avid cyclist (4k miles a year) I was advised to increase my protein intake by my coach. While they suggested 140g a day for me, I have found that almost impossible to hit without a 2 scoop protein shake every day for lunch. After trying a bunch of protein powders from the cheap to the boutique, I have settled on Momentous for their consistency, taste and how my stomach accepts it. I am still making FTP gains 5 years on, and I attribute much of this to my nutrition program.
