Thank you for your thoughts here .... Honestly, I think everyone is different and will respond to supplements in a unique way. I have worked w clients and they LOVE L-Theanine and it has done wonders for them along w 5-HTP. The amino acids can be tricky to navigate and that is why I love the book "The Mood Cure."
You are spot on w d3 and k2 needing to be present in order for calcium to be absorbed. CBD oil has worked wonders for me to support my sleep and therefore my mood :)
