Vitamin B12 is critical for red blood cell formation and proper immune and nerve function.  It works with Vitamin B6 to prevent heart disease.  Because vegetarians are often deficient in B12, it is important for them to have a good Vitamin B12 supplement.

The label of the Super B container has this information:

Thiamin (B1) as thiamin HCL     25mg

Riboflavin (B2)                                 25mg

Niacin (B3) as nicotinic acid        100mg

Vitamin B6 as pyridoxine              25mg

Folic acid                                           400mcg

Vitamin B12 as cyanobalamin    100mcg

Biotin                                                 100mcg

Magnesium (magnesium oxide) 25mg

Zinc as zinc gluconate                  5mg

Selenium as selenium yeast         50mcg

With reference to the brand of B12 that you may currently be taking, I will ask, “where did you purchase it?”  When I took my mineral therapy certification, I was trained with mineral compounds from that particular company.  We were taught that most companies make several different qualities of products.  The highest quality is the professional one sold only to certified mineral therapists and nutritionists.  The lower qualities are for retail sales to some therapists with the lowest quality in retail outlets.

What I can say about the Young Living supplements is that there is only one quality produced – the one that Gary Young uses for his own family and which is also offered to all of us.  I have used a lot of brands over my 68 years, and I have never found another one that consistently meets my expectations the way that Young Living does.  I know that I can confidently recommend the Young Living products because their quality is always the highest possible.

When I first began using the Young Living essential oils, I had been taking a number of supplements from other well-know companies for quite a while.  As I shifted to the Young Living supplements, I was totally amazed at the shifts that began occurring.  For instance, I was taking organic sulfur for 1.5 years with little change in my painful joints.  After only 3 weeks of taking Young Living’s Sulfurzyme, the pain was gone – and my hair was fuller and nails were stronger!  Needless to say, I have never considered taking other supplements again!

Perhaps the best way to evaluate a supplement is to ask yourself these questions:
Is it working?
Am I getting the results I expect?”
If the answer is “yes”, then take it.  If the answer is “no”, then try something else.
Does that make sense?
