if a doctor is recommending vitamin D why hasn't the CDC or the NIH recommend it?
Daily Dose Of Vitamin D Could Ramp Up Immune System, Doctors Say
FORT WORTH (CBSDFW.COM) – Your daily dose of sunshine could help ramp up your immune system, and studies are ongoing to find out if vitamin D could be helpful in the fight against COVID-19.
“Vitamin D got a lot of press over the last few years about everything, not just osteoporosis and bones but mental health and feeling well,” said Dr. James Herd, the Chief Medical Officer at Baylor Scott & White All Saints Medical Center.
A quick browse of Google reveals all sorts of articles about vitamin D and COVID-19.
Dr. Herd said while the exact relationship is still unclear, it does appear that patients with lower levels of vitamin D have a higher association with COVID-19.
“So there may be a protective effect of having a little bit higher vitamin D,” he said. “With my own patients personally I suggest even if they’re out in the sun, which is where you naturally make vitamin D through your skin and through sun exposure, try to get least 15 minutes a day of that, but also supplements.”
FM1 - good question.
Let me ask you one in return. Do you think everyone should make the same recommendations about Vitamin D? if so who should evaluate the evidence to determine what that recommendation is?
PS - what that doctor says is as you know no evidence that Vit D causes lower COVID severity. You would expect that association anyway because low Vit D is associated with many other known COVID risk factors. There have been similar associations with other diseases, when RCTs have not shown any causal relationship.
PPS - CDC does recommend Vit D:
Still, what constitutes the optimal intake of vitamin D remains a matter of some
disagreement. Current recommendations from the Institute of Medicine (1997) call
for 200 international units (IU) [5.0 micrograms (µg)] of vitamin D daily from birth
through age 50, 400 IU (10 µg) for those aged 51–70 years, and 600 IU (15 µg) for
those older than 70 years. According to the Dietary Guidelines for Americans (U.S.
Department of Health and Human Services and U.S. Department of Agriculture 2005) older adults,
people with dark skin, and people exposed to insufficient UV B radiation should
consume extra vitamin D from vitamin D-fortified foods or supplements. The
American Cancer Society Guidelines on Nutrition and Physical Activity for Cancer
Prevention echo this recommendation (Kushi 2006). Some experts say that optimal
amounts for all adults are closer to 800–1000 IU (20–25 µg) daily (Vieth 2007; BischoffFerrari 2006; Dawson-Hughes 2005). The tolerable upper intake level for vitamin D is 2000 IU
(50 µg) per day in North America and in Europe; however, some scientists are calling
for an upward revision (Hathcock 2007; Vieth 2006).
