Canadians' Vitamin D Levels are Falling!

So as a follow-up to my post on Friday regarding the potential for vitamin D to treat Alzheimer's disease, and all the other benefits that have been studied over the last decade, the latest statistics coming out of Canada, my home and native land, show that our vitamin D levels are falling! WTF?!

Are people that lazy that they can't go to a healthfood store and pick up an inexpensive bottle of vitamin D and supplement?! There should be NO reason why our vitamin D levels are falling in this day and age.

According to data from Statistics Canada, vitamin D levels for Canadians is declining significantly. The mean average vitamin D blood levels for Canadians between the ages of 6 and 79 years of age plunged to just 63.5 nmol/L in 2011 (a 6.2% drop from 67.7 nmol/L in 2009).

The reduction in vitamin D levels was consistently found across all age groups and for both sexes. Children age 6-11 years represented the largest decline at 10.2%. The lowest levels overall were found in young adults age 20-39. Males had vitamin D levels generally below females for all age groups with the exception of boys aged 6 to 11.


Only 68% had vitamin D blood levels sufficient for healthy bones (at a mere 50 nmol/L), with only 10% reaching optimal levels of over 100 nmol/L.

This reduction is very concerning since many research studies continue to show that people with lower vitamin D levels are at a much higher risk of developing numerous serious diseases.

The study also found that only 34% of Canadians took a vitamin D supplement and 85% of these users reached a cut-off level of 50 nmol/L compared with only 59% of people who did not take supplements.

Since vitamin D can be made naturally in your skin when exposed to UVB (ultraviolet B rays) in summer sunshine, this helped 75% of Canadians tested in the summer months to reach the 50 nmol/L cut-off versus only 60% of those tested in the winter

A large group of prominent vitamin D doctors, researchers and scientists recommend that people achieve optimal vitamin D blood serum levels of between 100-150 nmol/L for best overall health and disease prevention.

Studies of East Africans living naturally, with few clothes and high sun exposure, revealed that evolutionary human vitamin D levels are close to 115 nmol/L(4). This is a vitamin D level 80% higher than the new Canadian average of 64 nmol/L.

A study published in 2010 reported that if all Canadians reached a vitamin D blood serum level of 105 nmol/L we could expect an annual reduction in healthcare costs of $14.4B!

So who's not pulling their own weight in helping to reduce our healthcare costs (A.K.A. taxes)?!
