Questions

Is Momentous whey protein worth the price?

Only if the certification and taste matter to you. It is $69.99 for 25 servings, $2.80 each, or $52.49 a tub on Subscribe and Save, per Momentous. Comparable whey proteins cost $1.23 to $2.12 a serving. Garage Gym Reviews scored its price 1 of 5, and BarBend called it hard on the wallet.

Is Momentous Whey Protein Isolate NSF Certified for Sport?

Chocolate and Unflavored are each listed as NSF Certified for Sport at 20 g of protein per scoop (checked October 6, 2026). NSF's listings use the older name, Essential Grass-Fed Whey, and NSF lists other flavor-series isolates separately, so check your exact flavor.

Is Momentous Essential Grass-Fed Whey the same product?

Yes. Momentous renamed Essential Grass-Fed Whey to Whey Protein Isolate. NSF listings and the Garage Gym Reviews article still use the older name and an older $64.95, 24-serving price; the current tub is $69.99 for 25 servings, per Momentous.

How much protein is in a scoop of Momentous whey?

20 g of grass-fed whey protein, per Momentous. The ISSN protein position stand recommends 0.25 g per kg of body weight, or 20 to 40 g, per dose, so one scoop meets the low end of that range and heavier people would need more than one scoop to reach 0.25 g per kg.
