I tried L theanine and I feel it loses it's magic fairly quickly. I even took a months long break and never regained it's effects.
I read somewhere that you must take d3 with vitamin k2, to prevent calcium from going where it shouldn't. Regardless, people should have their vitamin d levels checked before supplementing.
GABA doesn't cross the blood brain barrier, so the effects of that are debatable.
B-complex is good, but the majority of them have very high doses and these doses can have serious consequences.
I hear good things about the cbd oil, and the fish oil is good as well.
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 :)
