How is vitamin D deficiency diagnosed?
The only way to know for sure if you have a vitamin D deficiency is with a blood test. This simple test measures your 25-hydroxyvitamin D (25[OH]D) level and is the most accurate way to diagnose the condition.
Always speak with your doctor to determine the best treatment and dosage for you. They will consider your age, health status and lifestyle to create a personalised plan.
Getting tested
You can get a vitamin D blood test at most clinics and hospitals. It's a quick, standard procedure in which a small blood sample is taken from your arm. The results will help your doctor determine your vitamin D status and guide your treatment plan.
What are the treatment options for vitamin D deficiency?
If you have low vitamin D, your doctor may suggest supplements to help restore your level. Most supplements use vitamin D3 (cholecalciferol) because the body absorbs it more easily than vitamin D2.1,2
Treatment options come in various formulations, so you can find one that fits your lifestyle.3
Tablets or capsules
Oral solutions (liquid form)
A convenient option if you prefer not to swallow pills. Depending on your doctor’s advice, oral solutions in safe higher doses can be taken once a week or even once a month, instead of every day. This is a great choice for:
- People who forget to take daily tablets
- Older adults who may struggle with swallowing pills
- Patients with special needs, such as those with cancer, elderly individuals with malabsorption issues and others requiring higher vitamin D doses, often benefit from these higher-dose oral solutions that standard tablets or capsules cannot provide.
Your doctor will recommend the right type and dosage based on your needs, age and health condition.
