- Don’t be alarmed if you happen to smell an odor in the B-100 and you’re used to B12 that has almost no odor. B6 has a noticeable odor contributing to the odor of this B complex product.

- B complex injections can slightly sting during the injection, this is normal and the sensation should subside shortly after the injection is completed. Those of you familiar with B12 injections will note this is uncharacteristic of B12 alone. The injection site can become red or slightly inflamed (red slight bump) afterward.
