    1. The addition of supraphysiologic doses of L-T4 (300 mcg per day) to an otherwise stable medication regimen of standard treatments resulted in a significant decline in depression scores during the 6-week, double-blind treatment phase. At endpoint (week 6), the mean HamD score showed a group difference of 3.7 points in favor of L-T4. Such difference is generally considered to be clinically meaningful in a short-term treatment trial for major depression. NICE used a 3.0-point difference in HamD change scores as a criterion of clinical significance.27

      This is consistent with the open label data. The dose is also similar. Combining this placebo-controlled trial with the three open-label supraphysiological thyroxine studies that I've seen, that is sufficient for me to conclude efficacy. Namely, Pfeiffer et al (350 mcg), Rudas et al (235 mcg) and Bauer et al (482 mcg)

      I would like to see if this study mentions nonresponders. Those three other studies found roughly a 50% response rate. Thus, the effect size in responders may be twice as significant.

    1. The authors demonstrated an inverse correlation between TSH and REE with a change of 15% for a TSH ranging from 0.1 to 10 μIU/mL. Of interest, free T4 remained within the normal range in all of the study volunteers. Nonetheless, the changes in REE with different LT4 doses were demonstrated in every patient [46].

      Thus, a 15% expected increase would be reasonable for a euthyroid subject such as myself. However, since T3 reduces weight compared to T4, it is possible the weight loss indicates greater energy expenditure.

    1. 22.3 per cent (−10.7; 95% CI, −15.6 to −5.7) in the diet group

      Interesting that the diet group worked better. I'd like to see if it's statistically significantly better than the drug group. It's also worth asking whether sodium was the only important dietary change, or if avoiding sodium caused many other dietary improvements.

    2. Sleepiness and neck circumference were significantly reduced only in the diet group (p = .007 and p < .001 for the time × group interactions, respectively).

      Fascinating. Neck circumference suggests that sodium intake may indeed be the significant dietary factor. The recommended diet wasn't even very restricted in sodium.

    1. CONCLUSION: This randomized double-blind, placebo-controlled clinical trial demonstrated that Amla could reduce frequencies of heartburn and regurgitation and improve heartburn and regurgitation severity in patients with NERD.

      Is there anything it can't do? I have noted, however, that larger doses cause nausea for me. That is, 3 or more grams on an empty stomach. I just vomited after taking 7.5 grams before my meal, but I have not yet established the causal link. It is the largest amount I've ever taken at one time. I suspect that it may have contributed significantly, but that it was also one out of half a dozen factors.
