Product Overview


  • Dietary Supplement

Advanced B-12 Complex combines the two active, coenzymated forms of B-12 - methylcobalamin and adenosylcobalamin (dibencozide) - with hydroxocobalamin, a form that is transported throughout the body in the bloodstream. Vitamin B-12 is required for nerve and brain health, and for healthy red blood cells. It also works together with folate to maintain normal levels of homocysteine. Coenzyme supplementation reduces the body's need to synthesize the active forms of vitamin B-12 from the synthetic form, cyanocobalamin.

Suggested Use

1 lozenge daily. For best results, allow to dissolve in the mouth before swallowing.

Other Ingredients

Sorbitol, mannitol, natural cherry flavor, stearic acid, and magnesium stearate.

Suitable for vegetarians. Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.


Note: If you are pregnant, may become pregnant, or breastfeeding, consult your health care professional before using this product.

I bought this product thinking it will help my stamina but it unfortunately is not making a big difference. Having said that it's easy and tastes just fine.

Thanks for your feedback!

I was looking for the most efficient Vitamin B12 and this one has everything I was looking for.

The Source Natural 'Advanced Vitamin B12 Complex' has both methylcobalamin and adenosylcobalamin. I have had digestive problems all of my life and this little tablet that dissolves in your mouth has been a great help.

Thanks for your feedback!

Got 30 tablets, not 60!

When I opened the box it felt to light, and I was expecting 60 tablets, but then I count them. to my disappointment I found only 30 tablets! I love Source Naturals, but this gave me a warning sign not to buy them again, unless someone in Iherb will compensate me.
