Product Overview


  • Sublingual
  • Dietary Supplement
  • Methylcobalamin & Adenosylcobalamin

Advanced B-12 Complex combines the two active, coenzymated forms of vitamin B-12 - methylcobalamin and adenosylcobalamin (dibencozide) - with folic acid. Vitamin B-12 is required for normal growth, cell reproduction, myelin and nucleoprotein synthesis, and the formation of red blood cells. Coenzyme supplementation bypasses the body's need to synthesize the active forms of vitamin B-12 from cyanocobalamin.

Suggested Use

1 tablet daily. Place tablet under the tongue and allow to dissolve slowly, altering its position to avoid prolonged contact with the same area.

Other Ingredients

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

Suitable for vegetarians and hypoallergenic: Contains no yeast, dairy, egg, gluten, corn, 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.

Do not use if either tamper-evident seal is broken or missing. Keep out of the reach of children.

Got 30 tablets, not 60!

Posted by 5604982341279592126 on Aug 18, 2015

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.

plastic bottle.

I can't fault it except for dissolvability & the plastic bottle. I choose Solgar over this every time.
