How it works
Think of vitamin B12 as a cellular engine builder — it is essential for DNA synthesis and the formation of red blood cells, which carry oxygen throughout your body. It also plays a critical role in maintaining the myelin sheath that protects your nerve cells, ensuring efficient nerve signaling [NIH ODS]. For this product, the specific ingredient data is not provided, but the mechanism for B12 is well-established.
