How Does Vitamin B12 Work?

Vitamin B12 Can Help You Lose Weight and Keep it Off

Obesity, insulin resistance, dyslipidemia, and cardiovascular disease have all been linked to low Vitamin B12 levels, according to researchers. Vitamin B12 is involved in the regulation of DNA coding for proteins (epigenetics) as well as many metabolic processes in the cell. There is mounting evidence that Vitamin B12-DNA interactions regulate lipid metabolism and play a role in fat deposition.

Crucial Vitamin for Optimal Function

Vitamin B12 is an essential vitamin because it is obtained entirely through diet. Vitamin B12 is found in animal products and fortified foods in the diet, but it can also be taken as a supplement. Vitamin B12 is important in the formation of red blood cells and regulation of gene activity. It is also used to produce myelin, the fatty insulator that surrounds nerve cells and speeds up nerve signaling throughout the body.

Improved memory
Improved mood
More energy
