The most controversial nutrient in the scientific world is probably vitamin B12. This vitamin is the only nutrient on planet earth to be produced by a soil bacteria. Only this bacteria can produce it, and neither an animal nor plant can. Many people do not know that, and automatically assume that this vitamin can be acquired by animal foods only, while the truth is that all vitamin B12 foods in our world, initially received their B12 content due to contact with the soil.
This vitamin is also controversial when it comes to supplements. While sub lingual tablets are pretty common, many people seem to be taking vitamin B12 injections for the false reasons. From B12 deficiencies to weight loss, these injections hype has grown so enormous, that it seems to be way out of control. Taking vitamin B12 injections for treating a deficiency is not a smart move unless the source of the deficiency is a malfunctioning intrinsic factor, the part in our stomach that decomposes B12 vitamin into our blood stream and to the cells. People having difficulties with this organ can not absorb B12 from any oral source, which makes these injections the only possible choice for them, but for other people, it is just a painful treatment that could have been avoided by using less-radical B12 supplements.
Also, taking B12 injections for weight loss purposes is not smart either. The only thing B12 does is boosting our metabolism and thus make us more likely to do some exercise and lose some calories. The point is, however, that you can get the exact same benefits by consuming any supplement or source of the active form of this vitamin, such as sub lingual tablets, intra nasal spray and gel, and of course ‘regular’ natural foods that are rich in vitamin B12, which can be found anywhere. Make your choices carefully, this is your health.
