VITAMIN B- 12 is an essential nutrient that helps to keep nerve and blood cells healthy, and helps to make DNA—the genetic code found in nearly every cell of the human body.

The best food sources for vitamin B- 12 are beef liver and clams. Fish, meat, poultry, eggs, milk and other dairy products also contain vitamin B- 12. Some breakfast cereals, nutritional yeasts and other food products are fortified with vitamin B- 12.

Taking a vitamin B- 12 supplement is necessary for those who don’t get enough vitamin B- 12 or who may have trouble absorbing it from food sources. That includes:

 Older adults, over the age of 50, who lose the ability to absorb B- 12 from

for your health

foods because of an age-related reduction of hydrochloric acid in the stomach

 Vegetarians and vegans, who are typically not eating the best food sources for B- 12

 Those with celiac disease, Crohn’s disease or pernicious anemia, as well as anyone post-gastrointesti-nal surgery.

USP-verified (see page 34) Kirkland Signature™ B- 12 is a convenient high-dose supplement taken sublingually— placed under the tongue and allowed to dissolve completely. It is provided in the form of methylcobalamin,a quick-dissolving, active version of B- 12, to increase response time in the body.
