A variety of common health problems are linked to low levels of the “sunshine vitamin”. Are you getting enough of this vital nutrient?

Despite official recommendations to give infants a daily vitamin D supplement, nearly 50% of parents forget to follow this advice according to a large new Danish study. Not only do the children risk weak bones, it also increases their risk of infections and autism, other studies suggest.

Vitamin C is also known as ascorbic acid and L-ascorbic acid. Most animals are able to synthesise vitamin C by means of a stepwise, enzymatic conversion of glucose (dextrose). However, humans, apes, guinea pigs, and certain other animals have lost this ability during evolution. The largest concentrations of vitamin C are found in the white cells of the immune defence, the pancreas, the testicles, and the ovaries. Vitamin C is water-soluble and as it is not stored in the body, we depend on regular intake of the nutrient. Vitamin C is destroyed by light, heat, boiling, freezing, preservation, and storage (including winter storage of vegetables and fruit).

Vitamin D is important for calcium uptake and bone health. According to a placebo-controlled follow-up study published in the American Journal of Clinical Nutrition, children whose mothers supplemented with vitamin D during their pregnancy continue to have stronger bones, even at the age of seven years.
The pregnant women in the study took 25 micrograms of vitamin D, which is more than twice the officially recommended intake. It is generally important for the child’s health that its mother has optimal vitamin D levels in the blood during pregnancy and while breastfeeding.

Bone fractures can be fatal, especially in old age where hip fractures typically result in hospitalization and early death. According to a study from Edith Cowan University in Australia, increased intake of vitamin K1 from foods like spinach, cabbage, and other vegetables lowers the risk of bone fractures later in life. Vitamin K1’s positive effect on bone health is linked to the fact that K1 is converted into vitamin K2 in the intestine, and vitamin K2-dependent proteins clear calcium from the bloodstream and embed the mineral in bone tissue.

Calcium and magnesium are vital for our bones, nervous system, muscles, heart, blood pressure, and many other functions. It is essential to maintain the right balance between the two minerals that work in a team and can easily be compared to yin and yang. Vitamin D is also needed for the uptake and utilization of the minerals. Still, deficiencies of all three nutrients are widespread and that increases the risk of infections, neurological disturbances, muscle cramps, constipation, hypertension, osteoporosis, cancer, and a number of other grave diseases. In our part of the world, many people get too much calcium from dairy products and supplements. That can disrupt the delicate balance between calcium and magnesium and result in oxidative stress, chronic inflammation, and cell death.
