Spinal discs do NOT have a direct blood supply. There are no arteries that feed the disc with oxygen and nutrients. Therefore, discs of the spine must receive their oxygen and nutrients from a different source. Normal, healthy discs are “fed” and oxygenated by the constant recycling of the disc fluid that occurs with spinal joint movement. This joint motion “sucks” in fluid filled with oxygen and nutrients and “pumps out” waste fluid.

Hate standing while working? No problem – just don’t forget to stand up every so often, even if it’s just to walk to the kitchen and back.
