Each week we will aim to bring out a concise email that provides 4-5 key pieces of information addressing a specific issue in clinical therapeutics.
This week: Vitamin D
Diana Chau, Regional Pharmacist Manager, Ward MM
As we grow older, our levels of circulating vitamin D decrease. This is due to a number of factors such as poor diet, poor renal function, poor digestion, less exposure to sunlight, decline in vitamin D reduction and increased degradation.
- According to experts, vitamin D deficiency is defined as a serum level of less than 50nmol/L.
- A level of under 29nmol/L is classified as moderate deficiency, whereas a level of less than 12.5nmol/L is severe deficiency.
- When it comes to supplementation, it is common for doctors to recommend a standard dose of 1000IU.
- In patients newly diagnosed with moderate to severe deficiency, supplementation with only 1000IU daily is only enough to burn through daily requirements, but will prove difficult to increase serum levels.
- Current guidelines recommend 3000-5000IU initially for 6-12 weeks before dropping back to 1000-2000IU daily.
- Please remember that Vitamin D is readily available in capsules, tablets as well as drops for patients with swallowing difficulties.
