How to Take Methyl B12

Feb 5, 2011 | By Leigh Wittman

Vitamin B-12 supplements are derived from a variety of sources. According to "Contemporary Nutrition," cyanocobalamin is the most commonly used source for vitamin B-12, although hydroxocobalamin, methylcobalamin and 5-deoxyadenosylcobalamin are also sometimes used. Methylcobalamin, commonly referred to as "methyl," is typically sold as lozenges. Methyl B-12 is thought to be more easily absorbed than other forms of vitamin B-12 because it is already in a usable form, whereas cyanocobalamin needs to be metabolized by the body for use. Vitamin B-12 plays a key role in the formation red blood cells, the normal functioning of the brain and nervous system and in the metabolism of nutrients.

Step 1

Read the instructions on your package of methyl B-12. Some methyl B-12 is taken daily, whereas other methyl B-12 is only taken a few times per week. Generally, lower dose methyl B-12 is taken more often than higher dose methyl B-12.

Step 2

Chew one lozenge, or allow it to dissolve in your mouth, as directed by the package or your physician.

Step 3

Take the lozenges as frequently directed by the package instructions or your physician. According to "Contemporary Nutrition," 1000 mg doses are commonly administered daily and 5000 mg doses are commonly administered 2 to 3 times weekly.

Tips and Warnings
