Are you still thinking about this? I've just seen it and it was over two weeks ago so maybe you've tried something now.
Of the ingredients listed, I find passionflower and valerian can be helpful for anxiety and stress. Also magnesium and B vitamins. The most effective over the counter mix for me is MyoComplex.
I don't know if you're open to this idea, but I go to a shop that sells them and "try out" different things by holding them in my hand. I have to take a moment, take a breath, close my eyes then focus on how holding one makes me feel. It's worth trying to see if you get a sense by doing this - I don't have any special abilities, it's just normal attunement that everyone has if they can connect to it. It's saved me spending money on things that wouldn't have any effect.
