“Make sure you eat your vitamins” is something you’ve probably heard from all of your elders growing up. And while all vitamins are necessary there are some that are more important than others. Vitamin B12 being one of the most important of them all.

The essential vitamin plays a role in the healthy formation of your red blood cells, the development and functioning of your central nervous system and even DNA synthesis.

However, despite knowing how important it is to our body, studies suggest that 47% of all people living in the sub continent have reported a “low-normal” deficiency of Vitamin B12.

How Long to Recover From Vitamin B12 Deficiency

But whether you suspect yourself to be low on B12 or have taken steps to treat yourself for the deficiency, waiting until you fully recover can be seriously frustrating.

Thus, in the sections that follow, we’ve taken it upon ourselves to let you know how much time your treatment could take in addition to the symptoms you can expect to experience due to your vitamin B12 deficiency.

How Fast Can You Recover from Vitamin B12 Deficiency?

The time it takes to recover from a Vitamin B12 deficiency is different for each individual and it depends on how deficient you are in the essential vitamin. Plus, it also depends on what kind of treatment you’re receiving.

For instance, if your health care provider has detected that you’re suffering from low B12 levels then they’ll offer you one of two treatment methods:

  • A shot containing 1 mg of B12 injected straight into your muscles.
  • An oral supplement that contains a high dose of a B12-supplement.

Historically intramuscular injections have been proven to work faster than oral supplements. As they inject the vitamin straight into your bloodstream as opposed to oral supplements which have to first be metabolized by your body before being sent into your bloodstream.

However, the only way you’ll recover quickly, even with injections, is if you’re only mildly deficient in the vitamin and are only showing minor symptoms.

Examples of minor symptoms include mild fatigue, loss of appetite and headaches which a 1 mg shot of vitamin B12 should be able to improve in just a few days.
