Corrections

What changed in the articles

Every change that alters what an article claims is listed here, with the date and the reason. Style edits are not included. A corrected article is not a less reliable one: it is one that has been re-read.

The rule behind this page is described in the method. To report an error: contact.

    Zinc: not just for immunity, it is helping my beard grow

    The testimony about colds had been shrunk to "once or twice a year, which gives few points of comparison". The observation was about going from five or six episodes a year to one or two. The sentence was restored to its real size, and the title rewritten around the query people actually type.

    Glycine and deep sleep: what 3 g actually do

    The limit set against the testimony was miscalibrated. The wearable validation study cited measures agreement with polysomnography on a given night: it says nothing about a device's ability to track a change within the same person. The section was rewritten around the gap, with three reconciliation hypotheses, and a rule added to the method: a limit states what it invalidates and what it leaves standing.

    Vitamin B12: the deficiency that looks like early dementia

    The article stated that vitamin B12 was absent from the blood panel described. That was wrong: it was there, and it was low, like B9. The sentence was removed, the callout corrected, and three medical terms explained: atrophic gastritis, metformin, proton pump inhibitors.

    Lion's Mane: my dreams changed, and that proves nothing

    A sentence credited the author with knowing the mushroom's reputation for dreams before taking it, which grounded an expectancy-effect argument. That was false: he had only read about the cognitive side. The sentence and the argument were removed, and the real confounder named, several supplements started in the same month.

    Health data: GDPR gives you rights, not guarantees

    Complete rewrite around a distinction the first version did not make: a right provided by the GDPR is not a guarantee of outcome. It has to be exercised, with deadlines, exceptions and remedies, which the article now spells out.

    Supplement interactions: I was wrong about omega 3

    The previous version stated that omega-3s must be stopped before surgery. That is common hospital practice, but the OPERA trial, double-blind and randomised across 1,516 cardiac surgery patients, finds no increase in bleeding. The article was rewritten and opens with this correction rather than quietly removing the sentence.

  7. review

    Your motivation is not the problem

    Rewritten on primary sources. The first version relied on second-hand references; every claim now points to the original study.
