One in 3 deficient in vitamin D

A new review of 195 studies involving more than 168,000 participants in 44 countries has found that 37.3% of us are deficient in vitamin D – and that Europeans are more deficient than North Americans.

The study compared measurements of 25(OH)D, or calcidiol, in blood samples, which is deemed to be the most effective measurement of vitamin D status. Levels of below 50nmol/l were considered to be deficient.[1]

Calcidiol is the pre-hormone form of vitamin D, and is directly related to calcium absorption. This is why vitamin D is often recommended for those with osteoporosis, rickets and other conditions where bones need to be strengthened.

Bone density at age 20 linked to mother’s vitamin D status during pregnancy

A new study has shown that we need to start supporting our bone density much earlier that we imagined. We have known for some time that our bone density peaks in our 20s, and so it may be wise to actively nourish our bones through diet and weight-bearing exercise throughout our adult life. This study goes one step further, showing that the mother’s vitamin D status during pregnancy affects the health of her offspring’s bones in later years.

Vitamin D, Crohn's Disease and Colitis

A 2008 study measured the incidence of vitamin D deficiency in 130 Inflammatory Bowel Disease patients (94 with Crohn’s disease and 36 with colitis) aged 8-22, and found a convincing correlation. This was no coincidence; vitamin D deficiency seems to play a causative roll in Crohn's Disease.

Vitamin D - Hypertension and heart disease

A recent review of 11 randomised, controlled trials showed an ability of vitamin D to help lower blood pressure in some cases. More striking results were shown in a study that followed 548 heart attack patients over 6 years, and showed that those with the lowest vitamin D levels had a 378% (Yes, three hundred and seventy eight!) increased risk of death from a further cardiovascular event.

Vitamin D and Diabetes

Studies have looked at vitamin D’s relationship to both types of diabetes, and lower concentrations of blood serum vitamin D have been noted with both types. Of particular note is vitamin D’s ability to lower, and therefore improve, insulin resistance, which is important for those with type 2 diabetes. A 2009 New Zealand study put forward that optimal blood serum levels for insulin sensitivity are between 80-119nmol/L48, which is much higher than the levels usually denoted as adequate.

How Vitamin D Triggers immune response

​Vitamin D has now been shown to be instrumental in triggering T-cell response in the immune system. “When a T cell is exposed to a foreign pathogen, it extends a signaling device or 'antenna' known as a vitamin D receptor, with which it searches for vitamin D,” explains Prof Geisler.
