Consumers should use caution with B-12 vitamin patch
A patch-delivery system is now available to consumers who want or need more of the vitamin B-12, an essential vitamin that plays a key role in the normal functioning of the brain and nervous system and for the formation of blood. B-12 is naturally found in meat, shellfish, milk, eggs and fortified cereals, but many people’s digestive systems do not absorb enough B-12, which can lead to vitamin B-12 deficiency. A B-12 deficiency can contribute to anemia, which can leave you feeling weak, lightheaded, depressed and tired.
