For people with B12 deficiencies it is popular to have injectable vitamin B12; however, research supports that oral administration of an appropriate dosage has been shown to produce as good of results as injectable preparations in treating vitamin B12 deficiency.* Methylcobalamin (vitamin B12) is active immediately upon absorption, while other forms (e.g., cyanocobalamin) must be converted to methylcobalamin in a two-step process. Methylcobalamin demonstrates exceptional activity in areas where other forms are simply not active. B12 supplementation is recommended for vegetarians and those with B12 deficiency.* It helps form red blood cells, prevents vitamin B12 deficiency, and helps maintain good health.* In people with low levels of B12, supplementation is very effective in improving energy levels and restoring mental function.* Check with your doctor or health professional on what is the best form and potency for you.
