Vitamin D May Improve Asthma Control in Children and Adults
On September 5, major global news agencies, including the BBC, Washington Post, NY Times, CTV News, CNN and MSN reported on this Cochrane Report.
- The report analyzed the data from 9 high quality studies lasting between 6-12 months to assess how vitamin D supplementation influences asthma symptoms and asthma attacks.
- The studies included a total of 435 children and 658 adults.
- Most of the participants had mild to moderate asthma.
- The participants received supplemental vitamin D (500 IU/day to 1200 IU/day in 8 studies; 4000 IU/day in 1 study) plus their regular asthma medication.
LIMITS OF THIS STUDY
- Most of the patients enrolled in the studies had mild to moderate asthma, so further research is warranted to determine whether vitamin D supplementation is effective for children and adults with severe asthma.
- It is not clear whether vitamin D supplements can reduce the risk of severe asthma attacks in all patients, or whether this effect is just seen in those who have low vitamin D levels to start with.
WHAT WAS ALREADY KNOWN
- Low vitamin D levels are associated with a greater risk of asthma attacks in asthmatics.
WHAT THIS STUDY ADDS
- Hospital admission or emergency department visits due to severe asthma attacks were reduced from 6% to 3% with oral vitamin D supplementation .
- Vitamin D supplementation reduced the need for steroid treatment (steroid treatment is used to reduce airway inflammation when a patient’s inhaler is no longer effective).
- The average number of attacks per person per year went down from 0.44 to 0.28 with vitamin D supplementation.
PLATINUM NATURALS VITAMIN D3
- 40% of Canadians are vitamin D deficient in the winter
- Just 1 drop or capsule per day
- 400 IU per drop for babies and children
- 1000 IU per drop or capsule for adults
