Anxiety is closely connected to the hormone leptin.
Leptin is a hormone released by your fat that controls all energy metabolism in the body. Clinically, I have found that leptin is closely tied to the level of RT3 on laboratory tests. However, this is not a requirement and altered thyroid function and inflammation to varying degrees can alter leptin signalling. Normalizing leptin involves:
1) Eating a seasonal diet, with adequate proteins, fats, and carbohydrates, as well as the appropriate proteins, carbohydrates, and fats.
2) Having proper light exposure (adequate sunlight, as well as reducing harmful blue light from LED/fluorescent lights, especially in the evening)
3) Having a proper circadian rhythm (sleep in the evening hours, awake during daylight hours, routine and evenly-spaced meals).
Additionally, it is necessary to avoid inflammatory foods and normalize any subacute microbial issues/heavy metals within the body. I have found EMF exposure to be a trigger to anxiety. In people with extreme EMF sensitivity, I have found herbs like alaria, or chanca piedra to be beneficial, in addition to p-5-p (activated B6).
I have found supplements such as l-theanine, pharmaGABA, phenibut, valerian, CBD isolate, rhodiola, ashwaganda, kava kava, and some b vitamins (specifically B5 and B6), l-tryptophan, 5-htp, and albizia. Usually it is just one or two of the above mentioned, depending on the underlying issues.
