That is great, Billye.

Cow's milk has high glutamine in it. (10 times more than human milk).
And glutamine is used to maintain the gut mucosa. About 50% of the glutamine we eat stays in the GI tract, for example.

You can speed up the glutamine by taking supplements, or using Whey protein
labeled with added glutamine as a smoothie. The aminos are predigested and more available to your body. Protein needs to be digested, before the aminos get thru. And good protein intake reflects on the bones.
Most of the quality Whey protein powders have glutamine added.
There have been studies showing improved lean muscle mass with Whey, in seniors.

Too much glutamine, and it goes to the nervous system, to form glutamate.
So one smoothie a day is plenty. But glutamine also fuels glutathione production in the liver, and glucosamine for joints. Both of these are important too.

I don't really know much about raw milk. Sorry about that.
