Vitamin B12 supplements come in a few different forms, and the one used can make a real difference in how it works in your body.
Cyanocobalamin is a synthetic, stable form of B12 widely used in supplements because it's inexpensive and shelf-stable. Your body converts it into active forms before it can be used.
Methylcobalamin is already in a form your body can use directly, without requiring that conversion step, and is more directly relevant to nerve maintenance and myelin support.
NeuroGenica specifically uses methylcobalamin rather than cyanocobalamin, reflecting its focus on nerve-relevant, readily usable nutrient forms.
