@colleenyoung Thanks, this is of course a subject that I am keenly interested in. One thing that caught my eye was that it said "melatonin, strontium (citrate), vitamin D3 and vitamin K2 (MK7; MSDK) on bone mineral density (BMD)". I am taking vitamin D3, and K2 along with a calcium supplement to make up for the deficit in my daily consumption of calcium but I take then during the day. I wonder if nightly actually makes a difference.

I will not take strontium. The medical authorities that I have trust and faith in do not seem to recommend it. I am also a bit horrified that people take borax! Boron may be helpful but Borax is not meant for consumption.

@lioness With my lack of immunity and wanting to once again be able to go out and be with people, I will be at the front of the line for the vaccine. I read that the first group will be health care workers and people in long term care facilities, and the second group will include the immunosuppressed. I hope and pray that it will not be a live vaccine or one that supports the immune system so that I will be able to have the vaccine.
