Sunscreens May Cause Vitamin D Deficiency

However, it is important to forgo sunscreen during these sessions because SPF 15 or greater decreases Vitamin D3 production by 99 per cent, the researchers said

While sunscreens are known to protect against skin cancer, they may be inadvertently making you deficient in Vitamin D, causing muscle weakness and bone fractures, researchers warned.

According to the study, published in the Journal of the American Osteopathic Association, nearly one billion people worldwide may be having deficient or insufficient levels of Vitamin D due to inadequate sun exposure related to sunscreen use.

“People are spending less time outside and, when they do go out, they’re typically wearing sunscreen, which essentially nullifies the body’s ability to produce Vitamin D,” said Kim Pfotenhauer, Assistant Professor at Touro University in California.

“While we want people to protect themselves against skin cancer, there are healthy, moderate levels of unprotected sun exposure that can be very helpful in boosting Vitamin D,” Pfotenhauer said.

In addition, the study also showed that chronic diseases like Type 2 Diabetes and those related to malabsorption, including kidney disease, Crohn’s and celiac disease greatly inhibit the body’s ability to metabolise Vitamin D from food sources.

Considered a hormone rather than a vitamin, Vitamin D is produced when skin is exposed to sunlight. Vitamin D plays a wide role in the body’s functions, including cell growth modulation, neuromuscular and immune function and inflammation reduction.

Spending as much as five-30 minutes in midday sun twice per week may help increase and maintain healthy Vitamin D levels.

High Doses of Vitamin D Can Severely Impact Your Kidney

Calcium levels may get worse before getting better in patients even after cessation of supplements, as vitamin D is fat soluble.

In a rare case, a 54-year-old man, after returning from a trip to Southeast Asia where he spent much of his holiday sunbathing, was diagnosed with kidney damage after he took high doses of vitamin D for years.

After referral to a kidney specialist and further testing, it was discovered that the man had been prescribed high doses of vitamin D by a naturopath, who recommended a dose of 8 drops every day, according to a study published in the Canadian Medical Association Journal.

Over two-and-a-half-years, the patient, who did not have a history of bone loss or vitamin D deficiency, took 8-12 drops of vitamin D daily, totalling 8,000-12,000 IU.

As a result, he had very high levels of calcium in the blood which left him with significant kidney damage.

The recommended daily allowance of vitamin D is 400-1000 IU, with 800-2000 IU recommended for adults at high-risk of osteoporosis and for older adults.

“Although vitamin D toxicity is rare owing to a large therapeutic range, its widespread availability in various over-the-counter formulations may pose a substantial risk to uninformed patients,” said Bourne Auguste from the University of Toronto.
