    Drs. Best Product are typically very affordable and very well made. You don't find a great deal if unnecessary additives, chemicals, etc. in their products. They are Vegan and use the better for of the the vitamin or nutrient as in this case using methylcobalamin which is natural as opposed to the cynacobalamin which is by product of a chemical reaction using cyanide it I remember correctly. This B12 does as advertised and certainly provides that extra energy needed and then some.
