Momentous sells this as its everyday whey: a grass-fed isolate sourced from European dairy farms, cold-processed and micro-filtered to keep sugar, fat and lactose low. Each serving gives 20 g of protein, and Momentous adds ProHydrolase enzymes, which it says help break down protein and reduce stomach upset. The formula has no gums, fillers or artificial sweeteners, and it is NSF Certified for Sport, the same mark carried by Thorne and Vega on this list. Flavor choice is wide, with chocolate, vanilla, strawberry, unflavored, spiced chai and mint chocolate, and it comes in 25 and 12 serving jars plus travel packs. The catch is price. A 25-serving jar costs $69.99 one-time, about $2.80 a serving, or $52.49 on subscription. A 30-day money-back guarantee and HSA/FSA eligibility help. If cost is not the deciding factor, this is as strong as the Thorne isolate on testing and cleaner on ingredients.
