indexVitamin D supplements can reduce COPD lung disease flare-ups by over 40% in patients with a vitamin D deficiency – according to new research from Queen Mary University of London. COPD (chronic obstructive pulmonary disease) includes conditions such as chronic bronchitis and emphysema, and is thought to affect more than 3 million people in the UK.

The NIHR-funded randomised trial, published in the journal Lancet Respiratory Medicine, included 240 patients with COPD in and around London. Half of the patients (122) received vitamin D supplements (6 x 2-monthly oral doses of 3mg) and the other half (118) received an equivalent placebo. The risk, severity and duration of flare-ups was then compared between the two groups.[1]

Vitamin A: Friend or Foe

Wednesday, 09 April 2014 by

It is well established that high retinoic acid (RA)  levels leads to teratogenic effects both in human and experimental models. Brain abnormalities such as microcephaly, impairment of hindbrain development, mandibular and midfacial underdevelopment, and cleft palate are all implicated.[1],[2] Ingested vitamin A, a fat-soluble vitamin, is delivered to the blood via the lymph system in

It’s not just your mood that the dark months of winter can influence. Low levels of sunlight also mean lower levels of vitamin D in the body. Vitamin D deficiency can trigger a range of diseases but until recently little was known about the exact biological mechanisms behind this. A research team at the University of Veterinary Medicine, Vienna has now decrypted one of these unknown molecular mechanisms. Vitamin D regulates the elasticity of blood vessels and thus also affects blood pressure amplitude. The results were published earlier this year in the journal Molecular Endocrinology.[1]

Having severe vitamin D deficiency may put people aged 65 years and older at more than twice the risk of having self-reported respiratory disease, according to an article published online May 6 in the Journal of the American Geriatrics Society.[1] The author Dr Hirani had in 2010 identified a similar pattern in older member of the UK population, and described it as a public health problem.[2]

Vitamin D Testing – What About Reliability?

Sunday, 10 February 2013 by | Comments: 1

Following a series of questions raised by colleagues concerning the accuracy of vitamin D testing we asked Doctors Data, based in the USA to respond to some of the general concerns raised, as their lab has recently undertaken an extensive review of the methodologies utilised, to prepare for the next generation of vitamin D testing.

Women who experience painful menstrual cramps could find relief from high-dose vitamin D3, according to new research – which suggests the dietary supplement could provide an alternative to painkilling drugs that are currently used.[1] Women with a history of severe menstrual cramps reported significantly less pain when they took an ultra-high dose of vitamin D five days before their next expected period.

The usefulness of vitamin D is increasingly being explored and as a result better studies are being collated and brought into publication. A study published the Journal of the American Geriatric Society in Dec 2011 reveals that Vit D status is linked to physical functionality and represents a suitable replacement option. Whilst the dose recommended is modest, it is able to record an improvement, higher levels may provide greater benefit depending on base line levels.

A group of experts has prepared a report on vitamin D supplementation for menopausal women after it was revealed that Europeans have suffered an alarming decrease in their levels of this vitamin. In their opinion, the ideal would be to maintain blood levels above 30 ng/ml. Vitamin D is essential to the immune system and

Cod Liver Oil vs TB

Friday, 06 January 2012 by

In a feature article in the Christmas 2011 edition of the well-known British Medical Journal, Professor Emeritus Malcolm Green revisited an 1848 study looking at the potential benefits of Cod Liver Oil in the treatment of Tuberculosis.[1]

In the study, carried out by physicians at the Hospital for Consumption, Chelsea (now the Royal Brompton Hospital), 542 patients with consumption (tuberculosis) received standard treatment with cod liver oil. These patients were compared with 535 ‘control’ patients who received standard treatment alone (without cod liver oil).[2]
