Frequently Asked Questions
Is RAW Grass-Fed Whey Isolate appropriate for tested athletes?
Yes — with the highest available certification assurance. RAW Nutrition Grass-Fed Whey Isolate is Informed Sport certified, with every batch independently tested for 285+ WADA-prohibited substances before release. Creatine monohydrate, whey protein isolate, and the formula's other components are all permitted by WADA and NCAA. Tested athletes can use this protein with the most rigorous available third-party quality assurance behind it.†How does RAW Grass-Fed Whey Isolate differ from CBUM Itholate Protein?
CBUM Itholate uses the same Informed Sport certified, grass-fed Whey Protein Isolate base but is co-branded with Chris Bumstead's personal line. The protein quality, certification, and macro profile are essentially equivalent — the differences are in flavor offerings and branding. Ask Get Yok'd staff for the current flavor availability of each product to find the specific taste profile you prefer.†Can RAW Grass-Fed Whey Isolate be mixed with milk?
Yes — mixing with milk adds additional protein, calories, and calcium compared to water. For athletes managing macro precision, mixing with water provides the cleanest, most predictable macro count. For athletes who prefer a thicker, creamier shake and don't mind additional calories and carbohydrates from milk, dairy or non-dairy milks work well with this formula.†Is RAW Whey Isolate appropriate for individuals with lactose intolerance?
Whey Protein Isolate contains very low levels of lactose compared to Whey Protein Concentrate — the micro-filtration process removes the majority of lactose along with fat. Many individuals with mild lactose intolerance tolerate WPI well. Individuals with severe lactose intolerance or milk protein allergy should exercise caution, as this product is derived from dairy and the formula contains Milk.†
How to Use RAW Nutrition Grass-Fed Whey Isolate Protein
Mix 1 scoop with 8-10oz of cold water or your preferred beverage. Adjust liquid volume to achieve preferred consistency and flavor intensity — less liquid for a thicker shake, more for a lighter consistency. Can be mixed into oatmeal, smoothies, pancake batter, or other recipes. Not for persons with milk protein allergy. Peanut Butter flavor contains Peanuts. Cookies and Cream flavor contains Wheat. Manufactured on shared equipment that processes egg, fish, shellfish, peanuts, tree nuts, and sesame. Not for pregnant or nursing women without physician clearance. California Prop 65 Warning applies.†
