]]> 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.

The B-12 patchs, made by global nutraceticals company VitaSciences, are sold as an alternative to oral supplements and shots. The company has applied for a patent on the patch and mentions on its Web site a clinical study involving six volunteers. Each patch contains 1,000 micrograms of vitamin B-12 and is designed to be worn once a week for no more than 24 hours. The dime-sized patches are worn on the neck behind the earlobe.

The patches deliver nutrients into the circulatory system by absorption through the skin. A special membrane controls the rate at which the nutrients are absorbed, allowing the active ingredient to release at a consistent rate over a period of time.

But can that delivery system be trusted? Other patch-delivery systems have come under scrutiny lately for seeping too much of the active ingredient into the blood stream. Drug maker Johnson & Johnson has settled numerous in both the United States and Canada over its patch Ortho Evra. The patch was found to leak too much estrogen into the blood stream causing blood clots which led to strokes and even death in some women.

Earlier this year the company’s pain patch, Druagesic fentanyl, was recalled for leaking too much medicine into some people who used them. That overdosing caused addictions and deaths in some users. While the fentanyl patch has been recalled, Ortho Evra is still widely available for use as birth control.

Vitamin B-12 toxicity, or having too much vitamin B-12 in your system, is uncommon but can have serious side effects. Side effects of vitamin B-12 toxicity include diarrhea, feeling of swelling over the entire body, blood clots in the legs and signs of an allergic reaction such as hives or rash; itching; swelling of the lips, mouth or throat; wheezing or other difficulty breathing.

The B-12 patch is still in a testing phase, and there don’t seem to be any reports so far of adverse reactions, but it is important to be aware of possible dangers based on experience from this type of delivery method. Those who suspect vitamin B-12 toxicity should consult a medical professional.
