I'm glad I could help. I don't think there is enough medical research yet to conclude that magnesium is beneficial. Studies have stated that magnesium has a soothing effect on the nerves. It could help you but it is not an alternative to medication. I take supplements in addition to my medication. I was recently prescribed neurontion in addition to Paxil. Neurontin does have clinical trials that prove it's effectiveness with social anxiety. I think the neurontin is helping me.
I don't know how long you have been suffering from anxiety but I'm sure you know to go to a psychiatrist rather than a regular doctor. Doctors don't know much and are not up on the latest treatments and combination therapy.
I am convinced that in addition to meds, diet and exercise are key. You can have a tremendous impact on your anxiety level.
Too many people who are in need of relief will spend there money on supplements that have not been proven to be effective for their disorder.
I'm happy to hear that you are interested in clinical research.
