You’re cherry picking papers. Others have already shared other studies showing no significant effects of Vitamin D intervention.
For any popular supplement you can find someone publishing papers with miraculous results, showing huge effect sizes and significant outcomes. This has been going on for decades.
With Omega-3s the larger the trial size, the smaller the outcome. The largest trials have shown very little to no detectable effect.
I think a lot of people are skeptical about pharmaceuticals because they see the profit motive, but they let their guard down when researchers and supplement pushers who have their own motives start pushing flawed studies and cherry picked results.
> In other words, if the effect on antidepressants vs placebo is ~0.4, and the effect of a placebo vs no placebo (just time) is ~0.7, that means the majority of the effect of antidepressants & OTC pain meds is due to placebo.
You keep getting closer to understanding why these effect size studies are so popular with alternative medicine and supplement sellers: They’re so easy to misinterpret or to take out of context.
According your numbers, taking Tylenol would be worse than placebo alone! 0.4 vs 0.7
Does this make any sense to you? It should make you pause and think that maybe this is more complicated than picking singular numbers and comparing them.
In this domain of cherry picking studies and comparing effect sizes, you’ve reached a conclusion where Vitamin D is far and away more effective than anything, placebo is better than OTC pain medicines, and OTC pain meds are worse than placebo.
It’s time for a reality check that maybe this methodology isn’t actually representative of reality. You’re writing at length as if these studies you picked are definitive and your numeric comparisons tell the whole story, but I don’t think you’ve stopped to consider if this is even realistic.
