Medium chain triglycerides offer the potential to elevate ketone levels and have a number of evidence-based application. In this post, Dr Cliff Harvey looks at the evidence behind the use of MCTs.
While saunas are known to be beneficial to health (by inducing ‘heat shock proteins’) and might even aid hypertrophy (muscle growth), the evidence for a ‘detox’ effect is less clear. It is plausible, as the skin is a major excretory organ and can help the body to eliminate toxins, and the increased metabolic activity and catabolic processes initiated by heat-shock proteins may amplify this. Research is lacking although a few studies have shown some isolated findings for an effect of saunas on detox At this stage though, research is lacking although a few studies have shown some isolated findings for an effect of saunas on detox, including improved healthy questionnaire scores and reduced neurotoxicity findings.1, 2 References 1.

Reviews of the evidence have shown that there is little meaningful evidence to support the use of evening primrose oil (EPO) for breast tenderness or dermatitis.1, 2 But one review has suggested a benefit (versus drugs used for treatment) for breast pain. It should be noted that the studies cited within these reviews still offer many conflicts.2 There is only limited data on the use of primrose oil for schizophrenia but a Cochrane review of this application found no clear effect of EPO supplementation on schizophrenia.3 Primrose oil is probably not worth taking References 1.
