Now speaking of Tryptophan
Irregardless if there is a connection to the parasite studies I mentioned
earlier, raising tryptophan levels seems to help alleviate panic attacks.

Besides being a safe and effective alternative to prescription drugs
when it comes to treating depression and anxiety, studies have
shown that 5-HTP (and its precursor, tryptophan) can also help
ward off panic attacks. In a simple yet elegant double-blind study,
researchers gave 20 patients with panic disorder and 19 normal
control subjects a drink containing amino acids (including
tryptophan) or a tryptophan-free drink that caused an 80%
decrease in plasma tryptophan levels.6 Four hours later, both the
patients and the controls were given a CO2 “challenge” when they
breathed normal air that was infused with 5% CO2.
In the patients with panic disorder, the CO2 challenge induced
panic attacks, while in the controls there was no evidence of panic.
Furthermore, those patients who had consumed the
tryptophan-free drink had even more intense panic attacks than
those who had consumed the tryptophan-containing drink. The
researchers concluded, “Serotonin may directly modulate anxiety in
patients with panic disorder. This may underlie the efficacy of
serotonergic antidepressants in treating panic disorder.” (The term
serotonergic means serotonin-related, so this would include
tryptophan, which is converted to 5-HTP, which is converted to serotonin.)
And 5-HTP Alleviates Panic AttacksA more recent study described how 5-HTP supplementation
alleviated panic symptoms in patients with panic disorder.7 This
randomized, placebo-controlled, double-blind study examined 24
patients with panic disorder (13 men and 11 women, average age
40) and 24 normal controls. The patients were given either a
200-mg capsule of 5-HTP or placebo; 90 minutes later, they were
subjected to a 35% CO2 challenge. Immediately before and after
the challenge, the patients’ levels of anxiety and panic symptoms
were measured, using standardized tests.
The results showed a clear benefit from using 5-HTP. In the authors’
words, “Panic anxiety and symptoms, as well as the number of
panic attacks following CO2 inhalation, were significantly reduced by
5-HTP in panic disorder patients. No such effect was observed in
healthy volunteers.” It is noteworthy that 5-HTP exerted its calming
effects in a span of less than 2 hours, in contrast to the 3 to 6
weeks that it takes for prescription drugs such as Prozac to
alleviate panic attacks.

supplements as mentioned in this study. So this might be another
way to approach the problem without taking strong antidepressants.
