Vitamin B-12 is commonly added to energy drinks. It is also supplied in different forms such as liquid, injection, nasal spray, and transdermal patch. Vitamin B-12 Transdermal Patches are especially suitable for patients whose digestive absorption is impaired. The transdermal delivery option may be the only option for patients with inborn problems concerning the methyltransfer pathway.
A Vitamin B-12 Transdermal Patch is applied to the skin to facilitate delivery of the compound to the bloodstream through the skin. The Vitamin B-12 compound is contained in the matrix of the patch and is diffused through the stratum corneum layer of the skin onto the dermes layer, and finally to the bloodstream of the user. The patch has a fabric backing where the skin-adhesive matrix is attached.
