I have been suffering from social anxiety and depression. N few days back I came across a book 'The mood cure by Julia Ross. It suggests different treatments for anxiety through natural supplements along with the prescribed dosage. For the symptoms and problems that m going through, the author recommends a supplement named L- tyrosine and omega 3 fish oil. As well as 5-htp. These are all amino acids. I want to try them all but I still feel a bit doubtful since these are little expensive. Please suggest me if I should try them as per the prescribed dosage?
