A recent release described a newly-developed drug for postpartum depression. Effects of the drug are said to last 45days. Cost is greater than $10,000 USD. No mention was made at all of nutrients.
I seemed to recall a connection between postpartum depression and B12; a quick search on regular Google came up with these two articles (there probably were others, but I stopped looking):
2012
ncbi.nlm.nih.gov/pmc/articl...
2021
ncbi.nlm.nih.gov/pmc/articl...
Why is there such hubbub about a new drug that delays postpartum depression symptoms for 45 days at a cost exceeding $10,000, and no mention of nutrients? I don't know for sure, but assume the prevalence of a market-based, profit-motive research model might have something to do with it.
