    Optimal vitamin D intake may be at least 2,000 IU daily

    As most people supplementing with vitamins know, the daily RDA for vitamin D has been set at 400 IU (in some countries up to 800 IU) daily, despite no evidence that such doses do anything beneficial, including even the basic target - preventing rickets. More recent studies have argues that the...

    Important role of copper in schizophrenia (transporters) (Vitamin D and A)

    Worth posting this in its own thread, copper looks to be highly significant in schizophrenia, where blood levels tend to be higher than normal BUT brain levels lower in copper regardless (due to defective copper transport) so problem is with transport typically instead of levels, leading to...

    Lack of Calcium cause of my bleeding?

    I have been dealing with profuse bleeding issues for last 6 years (I'm female) and other than having a progesterone:estrogen ratio of 5:1, I think I'm very low in Calcium which is contributing to the problem. Also very low in Vitamin D. Whilst the hormones may be causing the inability to stop...

    Higher doses of vitamin D, other steroids, may be needed in obese people

    The title, at least in regards to vitamin D, is something Ray commented quite a few times when people asked him what the optimal dose for raising vitamin D levels was. His response always cautioned that there is no one-size-fits-all due to the fact that in obese people vitamin D can accumulate...

    Vitamin D deficiency and low, not high, dopamine drive schizophrenia

    One of the most persistent medical myths can be found in psychiatry. More specifically, in the category of psychotic mental disorders. Schizophrenia is perhaps the most widely studied representative of such conditions and the prevailing dogma/hypothesis about schizophrenia (and other psychotic...

    Vitamin D is a ‘Game Changer’ for Patients With GI Cancers

    The actual title of the article and I agree with that statement since the study demonstrated that taking just 2,000 IU vitamin D daily reduced relapse/death by 30%+ for a number of different GI cancers that have seen their rates skyrocket recently, especially in people under 40 years of age. The...

    Vitamin D may prevent atrial fibrillation (afib)

    Some good news to all the people with this condition. Their numbers are, unfortunately, steadily rising and Big Pharma has produced "wonderful" (and actually, fraudulent) new drugs such as Xarelto to "help" them, with the end results of afib rates still rising and Xarelto becoming one of the...

    Vitamin D may prevent/treat migraine in humans

    Yet another chronic and debilitating condition may turn out to have a surprisingly cheap, widely available, and safe solution. Namely, vitamin D. In pharma research, a new drug that demonstrates effectiveness for a specific condition of just 20% over a placebo group is considered a very solid...

    Vitamin D may ameliorate/resolve (allergic) asthma

    It looks like vitamin D may be the "vitamin" (actually, seco-steroid) analog of aspirin - i.e. there is hardly a condition where this humble "vitamin" has not demonstrated beneficial effects. The new study now adds asthma to the list of chronic, debilitating (and potentially lethal) conditions...

    Low Vitamin D (25OHD) Or Calcium Deficiency?

    Hello everyone, I have seen some people testing both their storage (25OHD) and active (1,25OHD) vitamin D, and those with low storage D had almost always high active D. Reading on the connection between 1,25D and PTH has brought me to the hypothesis that possibly people with low storage D /...

    Vitamin D may prevent dementia / Alzheimer's Disease (AD)

    The study is observational and does not really include information on specific dosing, but it was written in a way that suggests any exposure to vitamin D over a year was linked to significantly lower risk of both getting dementia/AD and/or dying from it over the next 5 years. Considering the...

    Vitamin D supplementation may lower suicide risk by 50%

    Suicide rates have been rising for the last 20+ years and have truly gotten out of control since the pandemic started. As usual, the mainstream version is that this is not an environmentally-driven issue but a "complex" interplay of genetic factors and poor lifestyle choices. As such, medicine...

    Vitamin D Reduces TMAO From High-Choline Diet, Promotes Non-Atherogenic Microbiome

    The role of trimethylamine n-oxide (TMAO) in human disease has been quite controversial. The carnitine/choline in red meat and eggs had been purported to generate trimethylamine (TMA) via bacterial metabolism, which then goes on to become TMAO via the action of hepatic FMO3. The often-promoted...

    Vitamin D may prevent (and even reverse) uterine fibroids

    Yet another big win for vitamin D, much to the chagrin of the medical establishment, which has been throwing "mud" (read: fake, ghostwritten studies) against vitamin D ever since it showed so much promise in human studies for both preventing and treating COVID-19. Now, the study below...

    Low vitamin D levels linked to premature death

    Another way to phrase the findings of the study is that vitamin D deficiency increases the risk of death from any cause. Another important finding of the study is that it was the levels of 25-OH-D (calcifediol, a biomarker of of cholcalciferol (vit. D3) supplementation) and not 1,25-OH-D...
