B12 is an extremely important nutrient, yet it is not naturally made by plants or animals: it comes from bacteria. While this vitamin can be found in meat products, this is not ideal for people concerned about their health.
You can get B12 through fortified plant milks and cereals, spirulina, and some kinds of seaweed, but sometimes supplementation is ideal.
This B12 supplement is plant based, meaning that it is derived from sources that are alright for vegetarians and vegans. This also means our bodies will have a better time absorbing the nutrient.
