Dr. John Campbell is “completely satisfied” that high-dose vitamin D supplementation would stop many circumstances of dementia, notably Alzheimer dementia, which is 75% of all dementia circumstances. He takes 4,000 IU of vitamin D/day plus 100 mcg of vitamin K2. Unclear to me if that’s year-round or solely in fall and winter, when there’s much less sunshine within the northern hemisphere. I assume it’s oral vitamin D3 (there are a number of kinds of vitamin D). Dr. Campbell didn’t say why he takes the K2. Click on for a transient evaluate of K2. In distinction to his vitamin D dose of 4,000 IU/day, U.Okay. well being authorities advocate a tenth of that — 400 IU — in autumn and winter.
A number of observational research hyperlink greater threat of dementia with blood ranges of vitamin D which are poor or inadequate. Blood ranges of 25-hydroxy-vitamin D below 25 mg/ml are notably linked to dementia. Dr. Campbell admits that it’s tough to show that enough vitamin D supplementation would stop Alzheimer dementia.
