Sublingual B12 is the best and fastest way for your body to absorb B12. It can help lower homocysteine levels and increase energy. Many CFS/FMS patients have a good response to B12 and it may help decrease brain fog. Before you start to understand sublingual B12 you need to look at how B12 can benefit you. It is a very important nutrient that helps to support your mind and body in so many different ways. It helps with your energy levels, emotional stability, as well as brain function and mental clarity. It helps to reduce the risk of heart disease and has been known to lower homocysteine levels as well. Although there are plenty of B12 supplements on the market, it is extremely important to choose sublingual B12 when looking to supplement your dietary needs. Regular B12 is not always absorbed properly into the stomach and although it may do some good, it is not the optimal way of getting every benefit that you need. Sublingual B12 on the other hand can be placed under the tongue and allowed to dissolve which means it will enter the blood stream directly through the blood vessels which is a much more effective way to raise the levels of B12 in your body. This will also give you the most benefits to your body. In particular, it can be extremely beneficial to your heart. When you have extremely large amounts of homocysteine you can actually increase the risk of coronary heart disease, stroke, as well as osteoporosis and Alzheimer’s disease. B12 works to lower these levels to prevent this from happening. Also, there are other problems with B12 deficiency as well. It can result in gastrointestinal problems, as well as neurological and hematological problems such as a decrease in red blood cell count, decreased energy, fatigue, and heart palpitations. If you have a severe deficiency you can end up with Anemia which can bring along a host of other problems. Neurological problems such as dementia, depression, and memory loss can also become quite noticeable with a B12 deficiency. This is why it is so important to have enough B12 in your body, and although you can get some with a multi-vitamin, it is best taken as a sublingual B12 supplement which can dissolve in your body much easier and more efficiently.
