Anyone have any experience using “Met-Rx ready to drink” pre-mixed protein shakes?
Short answer - No
Long answer - I have read that RTD’s are not very good sources of protein due to the manner in which the proteins are prepared, especially the heating mechanisms they go through and the preservatives included.
How is protein powder prepared? They don’t use heat for that? Heat breaks down enzymes but protein bonds are rather strong…they still have to pass the stomach wall (read H.Acid).
The METRX-RTD’s shakes are good. I used to drink them everyday when i worked at Vitamin Shoppe. However now i stick to powder becasue RTD’s are expensive.
Sorry, what’s RTD?
“Ready To Drink” I guess.
correct thor.
