Vitamin B12 is a water-soluble vitamin that is found primarily in animal-source foods and is especially important for those who are on a strict vegetarian diet. The methylcobalamin form of B12 is superior to the more common form, cyanocobalamin, as it is active immediately in the body after absorption, rather than having to be converted in the body to the active form.

Vitamin B12 has a range of uses in the body. It is needed to prevent anemia; it aids folic acid in regulating the formation of red blood cells, and helps in the utilization of iron. This vitamin is also important in energy production and the production of genetic materials DNA and RNA. In the nervous system, its primary role is in the production of neurotransmitters that help with memory and learning, and for brain health to help slow cognitive decline that comes with aging.

Methylcobalamin is essential in converting homocysteine into methionine, playing an important role in protein synthesis necessary for cardiovascular function. As such, it is important for the maintenance of a healthy cardiovascular system and the maintenance of good health. 

Natural Factors B12 Methylcobalamin is the biologically active form of vitamin B12. The quick dissolved sublingual tablets are immediately absorbed into the body by bypassing the digestive system.

  • Biologically active form of B12 
  • Quick-dissolve sublingual tablets for improved absorption 
  • Bypasses digestive track and goes directly into the bloodstream 
  • Suitable for vegetarians

Runs Large
Size: X-Large, Color: Dreamy Coral
Seems to be an okay shirt. It’s a little boxy and Definitely not slim fit. I’m an xl tee shirt guy so that’s what ordered. The body fits more like a 2xl but it’s not bad enough to bother returning. Kind of hoping it shrinks after a couple washes

Bad stitching
Size: Large, Color: Bright White
The shoulder seam missing stitching. So there was an inch hole in the seam. I stitched it myself but really should have returned for a replacement. I bought two others in different colors and the stitching was fine. I do love the fit of these t-shirts.
