Effective form of vitamin B12 that helps prevent mouth ulcers.
Mouth ulcers are usually not a serious condition, but getting them frequently can be a sign of low vitamin levels. Taking Cyanocobalamin can elevate your vitamin B12 levels and prevent recurring mouth ulcers.
To order Cyanocobalamin, simply answer a few questions online and choose the treatment you want. Then get it delivered straight to your door the next working day.
Cyanocobalamin is a synthetic version of vitamin B12 that helps to treat vitamin B deficiency. This can cause problems like indigestion, headaches and mouth ulcers. Mouth ulcers can be a result of many things, like accidentally biting your lip or cheek, but if you have recurring ulcers, it can be a sign of vitamin B12 deficiency.
There are three main ways a vitamin B deficiency can occur:
A vitamin B12 deficiency results in megaloblastic anaemia. This is characterised by large blood cells that don't function properly. Taking Cyanocobalamin can increase the amount of vitamin B12 in your diet, which can help prevent megaloblastic anaemia and reduce the recurrences of ulcers. However, this will only work if you have dietary insufficiencies. If you have an autoimmune disorder or malabsorption, you will need vitamin B12 injections.
Cyanocobalamin comes in a single dose of 50 micrograms. Your prescriber will tell you how many tablets to take each day, and this might vary depending on how deficient your B12 levels are. Generally, adults are advised to take one or two tablets daily while children are recommended to take one tablet daily.

Always make sure to take Cyanocobalamin as advised by your clinician. For mouth ulcers, the recommended dosage for adults and the elderly is one or two tablets daily. For children, it’s one tablet a day. You should swallow one tablet with water between meals. If you are prescribed two tablets daily, it's preferable to take one in the morning and one in the evening, so that your doses are as evenly spaced out as possible.
If you forget a dose of Cyanocobalamin, take it as soon as you remember. But if it’s close to your next dose, skip it and take the next dose at the usual time.
If you accidentally take more than the recommended amount, contact your doctor or pharmacist to seek medical advice from them.
