Why it made the stack
Key takeaways.
Protein per scoop, inside the 20 to 40 g per-serving range the ISSN position stand on protein recommends, with about 2.5 g of leucine.
Certified for Sport. NSF tests that what is on the label is in the jar and screens for substances banned in sport. Momentous publishes certificates of analysis on its site.
About 90 calories, 1 g of carbohydrate and under 1 g of sugar per scoop (unflavored). Momentous says it uses no gums, fillers or artificial sweeteners.
From the label
Every number, in plain sight.
The unflavored jar is just whey protein isolate and an enzyme blend. Flavored jars add natural flavors and a sweetener (monk fruit and stevia in chocolate and vanilla, Reb M in strawberry).
Unflavored, 25-serving jar, from the Momentous supplement facts panel, checked October 22, 2026. Flavored versions have slightly larger scoops with the same 90 calories and 20 g of protein. Always read the label on the jar you buy.
† Daily Value not established. Other ingredients: none. Contains milk. Typical leucine: 2,467 mg per serving.
What the research says
Ingredient by ingredient.
Whey protein isolate
The ISSN says most people who exercise do well on 1.4 to 2.0 g of protein per kg of body weight a day, spread over meals of about 20 to 40 g, each with 700 to 3,000 mg of leucine. One scoop lands inside that range. A large meta-analysis of randomized trials found protein supplements added muscle and strength gains during resistance training, with little extra benefit above about 1.6 g/kg a day in total.

ProHydrolase® enzyme blend
A blend of protein-digesting enzymes. Momentous says it supports protein breakdown and digestion. We found no strong independent evidence that it changes muscle results, so we treat it as a minor addition rather than a reason to buy.

Grass-fed sourcing
Momentous says its whey comes from grass-fed cows on European dairy farms, not treated with rBST, and is cold-processed and microfiltered. These are Momentous's own sourcing claims; the research benefits above come from the protein itself.

Before you buy
What you should know.
- Most useful if your diet falls short. Protein powder is food in a convenient form. If you already hit your daily protein target from meals, an extra scoop adds little.
- It contains milk. Isolate has most of the lactose removed, but Momentous does not call it lactose-free. If you are very sensitive to lactose or allergic to milk, skip it or ask your doctor.
- It's premium-priced. At about $2.80 a scoop at list price, you pay for the certification, sourcing and clean label. Lower-cost proteins can provide the same 20 g.
- Flavored jars have sweeteners. They are natural (monk fruit, stevia or Reb M), not artificial, but the unflavored jar is the one with nothing added.
- Check with your doctor first if you have kidney disease or have been told to limit protein.
Great fit if you…
- Train regularly and find it hard to reach your daily protein from food
- Want a short ingredient list with no gums or artificial sweeteners
- Compete in tested sport and want NSF Certified for Sport
How to take it
- 1 scoop in 8 to 12 oz of water, milk or a smoothie
- Use it to fill a gap in a meal or after training
- Spread your protein across the day, about every 3 to 4 hours
FAQ
Quick answers.
How much protein do I need?
The ISSN position stand puts most people who exercise at 1.4 to 2.0 g of protein per kg of body weight a day, in servings of about 20 to 40 g. One scoop of Momentous Whey gives 20 g.
Is it lactose-free?
Not guaranteed. Whey isolate has most of the lactose removed, but Momentous does not label it lactose-free, and it contains milk.
Do I need protein powder to build muscle?
No. Whole foods can meet your needs. Protein powder is a convenient way to reach your daily total when meals fall short.
When should I take it?
Total daily protein matters most. Spreading protein across the day, including after training, is a sensible way to use a scoop.
Is it safe?
Whey protein is a common food ingredient. If you have kidney disease, a milk allergy or have been told to limit protein, talk to your doctor first.
