Vitamin D Deficiency Can Lead to Dementia And Stroke

Despite this being an observational study, the analysis for extraneous factors has been strong enough that the authors believe the link between vitamin D deficiency and dementia/stroke is causal. As the study itself says, almost 20% of dementia/stroke cases could be prevented by simply supplementing with vitamin D. And since by supplementation such studies often … Read more

Even low-dose Vitamin D may prevent/treat dental cavities

Another study demonstrating that an “inevitable” conditions such as dental cavities may actually be preventable and, at least in its early forms, even treatable by vitamin D. The study immersed extracted teeth in different types of saliva with varying pH levels. One of the saliva types also came from volunteers that had been taking a … Read more

Vitamin D can prevent, and even reverse, the cancerization process

The study is on ovarian cancer but I don’t see why its findings won’t apply to all other cancers, as the study itself states, especially the ones forming in the abdominal cavity and involving the peritoneum. he study found that vitamin D can actually restore the “cancer” cells back to normal, which is reminiscent to … Read more

Milk or water are optimal drinks for (oral) vitamin D bioavailability

Just a quick post about something I thought many people will probably find interesting, considering the widespread use of oral vitamin D supplements. The findings of the study are a bit surprising, considering that vitamin D is one of the “fat-soluble” vitamins and as such is expected to be poorly absorbed from the GI tract … Read more

High-dose vitamin D could help fight HIV/AIDS

Actual article title, though I disagree with the “high-dose” qualifier as it corresponds roughly to a vitamin D3 dose of ~7,000 IU daily, which is not really a pharmacological dose. While the authors were not brave enough to claim that vitamin D supplementation could be an effective prophylactic measure for HIV/AIDS they did demonstrate that … Read more

Vitamin D2 (ergocalciferol), unlike D3 (cholecalciferol), ineffective for immune health

A very important study, with huge ramifications, considering most people taking prescription vitamin D are consuming vitamin D2 (ergocalciferol) as that is the only FDA-approved vitamin D variety available for oral use. The widely available OTC variety vitamin D3 (cholecalciferol) is not FDA-approved and doctors rarely prescribe it to their patients out of litigation fears. … Read more

Vitamin D effective in humans for preventing autoimmune diseases

A human study, one of the largest ever conducted, and covering virtually all major autoimmune conditions. Also, the study claims that this is the first intervention trial that looked at effects of vitamin D on developing autoimmune conditions, so the link is causal – i.e. we can now claim that taking vitamin D does prevent … Read more

Oral vitamin D3 may treat steroid-driven hair loss

A very interesting study, which demonstrates that a relatively low (5,000 IU) oral daily dose of vitamin D3 for 6 months, may be able to treat gender-specific (driven by steroids) hair loss. Now, the study participants were all female, with female-pattern hair loss (FPHL), however the findings should be applicable to the other gender as … Read more

Vitamin D may prevent/delay Type I diabetes

Vitamin D seems to be trying to take aspirin’s crown as a universal drug away. The study below is the latest evidence that this remarkable nutrient may have therapeutic effects in conditions that most doctors consider completely unrelated outside of vitamin D’s realm (e.g. calcium absorption). As per the study below, vitamin D joins niacinamide … Read more

Vitamin D3 anabolic, calcitriol catabolic for muscle/thymus

Several great studies, which will probably do little to calm down the controversy that seems to be brewing lately in the blogosphere over whether supplementing with vitamin D3 is beneficial or not. Namely, the last study below demonstrated direct muscle-anabolic effects from supplementation with vitamin D3 (cholecalciferol), in direct opposition to the known catabolic effects … Read more
