You really should get your Vit D tested when you see the doctor.

Low D depresses the immune system. Many people are fairly low in D levels today in the US. Get the test and if you are low, do not accept the RX D2 offered..as it doesn't work. D3 is the active form, and based on your tests, you can figure out a dose for that.

People who raise their D levels, often stop getting infections, and colds.
Stop the infections, and you stop the need for antibiotics which in the end carry a heavy biological price! (new studies show many antibiotics can cause neuropathies, by damaging your mitochondria in the cells).

The Kefir has TWELVE probiotic strains in it. Far more than any probiotic pill or yogurt. It is just fantastic!

I have had gall bladder issues all my life. I was born with a congenital condition called Malrotation of the GI tract. I have grade 2. I have had 4 major testings for gall bladder that all come back "normal" over the years. So I know how awful it is and I have found solutions for myself beyond the doctors.

I also avoid gassy vegetables, and that helps me. Cabbage and I have been enemies for 4 decades! LOL
