Interactions & dosage with Vitamin B12

Vitamin B12 is part of the B vitamin-complex and is vital for many functions and processes in the human body. We are required to gain a certain amount from our diets, however sometimes it is not always possible to gain an adequate level of vitamin B12 from food sources alone. To avoid a vitamin B12 deficiency we can receive vitamin B12 from supplement sources that are considered completely safe when taken orally at the correct doses.

Recommended dose:

Daily dose of 1-25 mcg of vitamin B12 is recommended daily

The recommended daily dose of vitamin B12 will depend mainly on your age and how well your body can absorb vitamin B12. Infants, children, older children and adults are all recommended different levels of vitamin B12, as well as pregnant and breastfeeding women and those over the age of 50. Different doses will also be advised for those with a vitamin B12 deficiency or pernicious anaemia, high blood levels of homocysteine or for preventing age-related macular degeneration (AMD).

Interactions

Major interaction (do not take this combination) ? Chloramphenicol

One of vitamin B12's main functions is producing new blood cells but Chloramphenicol might decrease new blood cells and when taken for a long time it might decrease the effects of vitamin B12 on new blood cells. Most people only take Chloramphenicol for a short time, so this interaction can be easily avoided.
