Products & dosage
Can I take too much Vitamin B12?
Vitamin B12 is generally considered safe with a very low risk of overdose — the body flushes out what it doesn’t use through urine. It can be used as frequently as once a day, but your age, general health, and lifestyle all matter. Always consult a doctor or your healthcare provider first, especially if you’re on other medication.
How often should I use B12 solution?
If you’re using B12 for general wellbeing — or you have medical records from your GP showing a diagnosis requiring a specific regime — the typical starting dose is 1000 mcg (one ampoule) once a week for four weeks, followed by a maintenance dose of 1000 mcg every one to three months.
Always consult a doctor or healthcare provider first to confirm what’s right for you.
Do I need a prescription to order vitamins?
In the UK, our vitamin range is available without prescription. For the US, all DHL orders include a prescription attached from our doctor. Other countries vary — in Asia and many other regions, vitamin B12 ampoules for deficiency (or vitamin solution) are available over the counter.
Always consult a healthcare professional before using such products.
