Physica Energetics Vitamin B Complex is supplied in a liposome formulation. One dropper (oral) per day provides a 60 day supply from one bottle - this is sufficient for most requirements. If you are very deficient in B vitamins and you have taken advice from a health care professional, then two droppers per day may be suitable.
Oral Liposomes are absorbed through the lining of the mouth and bypass the normal digestive / gastric process. Unlike conventional health supplements, liposomal nutrients can pass through the blood-brain barrier - this means that you will achieve optimum benefit at the cellular level.
