For some people, a “clean” dinner can end in fragmented sleep: awakenings, palpitations, a stuffy nose, itching. The…
ArticleFolate (vitamin B9) and mental fatigue: when the brain signals cell turnover, methylation, and homocysteine
Mental fatigue can be a biological language: when cell turnover increases and methylation slows, folate and…
ArticleIodine and mental clarity: when the problem is not a “slow thyroid,” but axis regulation under stress, caloric restriction, and non-iodized salt
In many cases, a “slow thyroid” is not a diagnosis: it is a thyroid axis adapting to stress, energy deficit, and…
