This post is in response to reports circulated through the Internet and publications that whey and calcium caseinate are “hidden sources” of monosodium glutamate, or MSG, and “free glutamate”. These reports are highly misleading.
Here’s why: To begin with, glutamate is one of the most common amino acids in food. It’s in fish, meats, dairy, mushrooms and vegetables. High amounts are found in tomatoes and in human breast milk. Whey and calcium caseinate also naturally contain glutamate, although in less concentration than in tomatoes or Mother’s milk. According to the International Food Information Council, the average intake daily of glutamate of typical person is 11 g. The human body, however, makes about 50g daily on its own because glutamate is needed for key metabolism and brain functions.
Monosodium glutamate (MSG) is the sodium salt of glutamate. Glutamate as “free glutamate” or MSG provides flavor to food and is used by the food industry to enhance flavors. It’s what you taste when you eat parmesan cheese, mushrooms, tomatoes, stews and soups. It would not be used in any sweet drinks. For more information about MSG, please see this publication by the International Food Information Council.
Not only is MSG or free glutamate not used in the shake, but no artificial flavors are used. In addition, because Isagenix’s source of calcium caseinate is produced by a highly complicated process by which to keep it undenatured, it does not even contain “free glutamate.” Of course, normal human digestion would eventually break down protein to its free amino acids to be absorbed.
Dairy proteins such as whey and casein have long been known for their superior nutritional profile. Whey is a protein that is quickly digested and absorbed whereas caseins are more slowly absorbed. We use whey and casein in a ratio that is studied for helping to preserve muscle, promote muscle growth if exercising, and assist in weight loss.
If you wish to know just how much glutamate (or any other amino acid) is in IsaLean Shake, please check the side panel. The amount isn’t “hidden”. It’s 4.2 g per serving. Also, don’t forget to notice the high-BCAAs, which are excellent for preserving muscle and promoting muscle growth when exercising.
