Why is MCT in protein powder? Added fat is different from protein

MCT means medium-chain triglycerides. In a protein powder, it adds a fat ingredient and may change energy content and texture; it is not additional amino-acid protein.

Read protein and MCT as separate ingredients

Cleveland Clinic describes MCT as a type of dietary fat and notes that powders can be mixed into shakes. A product’s scoop weight includes all its ingredients. The grams of protein on the nutrition panel, not the total scoop weight, tell you the labeled protein amount. [1][2]

The added ingredient does not guarantee an added benefit

Claims about energy or weight loss need evidence for the amount and use. The Cleveland Clinic overview cautions that many proposed MCT benefits remain uncertain and that larger amounts can cause nausea, abdominal pain or diarrhea. A protein powder does not need MCT merely to count as protein. [1]

Compare equal protein servings

Imagine a 35-gram scoop lists 25 grams of protein while another 30-gram scoop also lists 25 grams. The heavier scoop does not provide more protein. Compare the separate fat, carbohydrate and energy values and whether the added ingredients fit your intended meal. [2][1]
