Most efficient way to provide vitamins and nutrients when there is higher demand for them ( i.e colds/flu; intense athletic training; cancer; chronic disease like thyroid and fibromyalgia, convalecense, autoimmune disease heavy metal toxicity etc)
IV therapy is the administration of specific vitamins and minerals (i.e vitamins B complex, B5, B6, vitamin C, magnesium, calcium plus other minerals, nutritive substances and homeopathic) intravenously ( aka into the vein).
