I'm Dr. Berg, and we're going to talk about the pros and cons of sublingual liquid B12. B12 is an essential nutrient in maintaining red blood cells and supporting your nervous system as well as your DNA. Now the advantages of B12 is it really satisfies some deficiencies that you might have that can cause anemia which is low red blood cells as well as weakness, loss of appetite and also a condition called peripheral neuropathy which is that tingling on your fingertips and your toes after a diabetic situation. But here's the thing, just because you need some doesn't mean you need a lot. In fact the normal requirements are only in micrograms not milligrams, so don't go overboard because some of the side effects could cause hives, allergies, digestive problems and nausea. I'm also going to recommend that you not consume the synthetic version which is called Cyanocobalamin because that has a cyanide molecule. It's very toxic. Instead do the Methylcobalamin which is more natural.
