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.

B-12 good for energy?

Posted by Reviewer1246993 on Jan 09, 2017

This is supposed to improve mental 'acuity and energy. Some days it seems like it is doing this and some not so much. Could just be more than it can handle some days?

Readily Absorbed B12

Posted by Reviewer2666562 on Aug 28, 2016

This is a good way to get B12 absorbed into the body. It becomes necessary to increase B12 as we age. This helps keep me feeling young.
