For adults in the UK, the NHS advises considering a daily supplement containing 10 micrograms of vitamin D during autumn and winter. Some people are advised to consider it throughout the year. Check the NHS guidance for the groups this applies to.
Check the unit
Vitamin D labels may show micrograms, written as μg or mcg, or international units, written as IU. The NHS states that 10 micrograms is equivalent to 400 IU. Micrograms and milligrams are different units; do not treat them as interchangeable.
Check what you already take
Look at any multivitamin or other supplement you use before adding another product. If a clinician has given you a different dose or treatment plan, follow that advice rather than replacing it with general guidance from a fitness website. A pharmacist can help you check the labels.
Make reminders clear
Use the product name and label amount when adding a reminder in Gorivo. Set a schedule that matches the advice you are following. A reminder is an organisational aid, not a personalised dose recommendation.
You do not need to interpret a missed reminder as a reason to double a dose. Follow the product instructions or ask a pharmacist if you are unsure what to do.
