Key Information

Why Vitamin D Matters: It is essential for healthy bones, muscles, and energy levels. Low levels are a common cause of tiredness and general body aches.

The Main Source: Our bodies create Vitamin D from direct sunlight on the skin. However, in the UK, the sun is only strong enough to do this between late March and September.

The Solution: Because your levels are currently low, the most effective step is to take a daily supplement.

The Correct Dose: Look for a supplement containing 20 to 25 micrograms. Note that packaging sometimes writes this as 800 to 1,000 IU (International Units).

No Prescription Needed: You do not need a prescription. These are available affordably over the counter at pharmacies and supermarkets.

What Happens Next?

Please visit your local pharmacy or supermarket to purchase your supplements and begin taking them daily. This simple step is usually enough to return your levels to normal.
