Safe and effective way to maintain adequate levels of vitamin D
Vitamin D is known to benefit musculoskeletal health and emerging research is pointing to a possible protective effect offered against some cancers by maintaining adequate levels of this vitamin.
Canadians are being faced with two options to maintain vitamin D levels - taking vitamin D through vitamin supplements or deliberately seeking increased sun exposure. (Food sources do not provide sufficient supplies.)
- Most people receive enough UVB radiation from the sun to enable vitamin D synthesis simply by going about their daily activities during the spring and summer months. Very brief amounts of sun exposure appear to be required to maintain optimal vitamin D levels, probably in the region of a few minutes a day, although the exact amount for each individual is as yet unknown. There is no need to seek increased or prolonged sun exposure. During the winter months, a vitamin supplement should be taken.
- Canadians should avoid increasing their sun exposure since there is strong evidence that UV radiation from the sun is the prime cause of skin cancer. Skin cancer should not be minimized – melanoma caused the death of 880 people in Canada in 2006 and figures are on the rise. Basal cell and squamous cell carcinomas cannot be left untreated although such treatment can cause pain and disfigurement. Yet these diseases are mainly avoidable.
- Using sun beds to promote vitamin D production increase a person’s risk of developing skin cancer. The CDA, along with other organizations such as the World Health Organization (WHO), many US state governments, and authorities in Europe recommend that tanning beds not be used.
In summary: In order to lessen the health risks associated with skin cancer yet still reap the known and possible benefits of vitamin D, the CDA recommends people concerned about vitamin D levels take 1,000 international units of vitamin D supplements a day. These are safe to use and equally effective as the sun in maintaining healthy levels of this vitamin in the body while avoiding the risk of getting skin cancer.
