Nothing could be further from the truth.
Most B12 injections use a synthetic B12 in the form of CyanoCobalamin. This has to be "turned on" before it can used by your mitochondria to make energy. This activation process takes your precious energy, and releases cyanide into your body.
We ONLY use bioidentical, ACTIVE forms of B12, so you can use it immediately, without harmful byproducts.
