I don’t think so.
I have seen it work in numerous po₫eople including my daughter.Manic Depression is not uncommon in the city in Việt Nam where girls aare taught from birth to never let the sun touch their skin lest then can never get a husband. Igot one young lady out of that 20 years ago and she has proselytized sunshine to all the depressedw omen she has known with 100% success. For them it is 11 months of sunshine and a month to 6 weeks of no visible sun during during rainy season. That is when they get sad depressed again. D3 is not available to them so I send a supply to each family I know primarily to prevent flu/colds during rainy season but for the two I know who suffer depression in that time, too.
Do the research. Search Vitamin D and depressioin and/or Vitamin d and virus. Depression sources are harder to find because there only a few researchers and praticing MDs that have made those findings. itamin D3 is sunshine in a wee gelcap.It has kept me virus free for almost 30 years.
