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.

Sub B-12

Posted by Reviewer2882806 on Sep 27, 2008

I like that it has 2 active B-12's. Lozenge is smaller than Jarrow's so it has less sugar alcohol. Jarrow uses xylitol which is a little higher glycemic than sorbitol/mannitol. I am sensitive to all sugar in the morning. I would prefer stevia. This Source Naturals B-12 melted in about 10 minutes. It melts faster than Jarrow b-12 (20 min. melt approx). I prefer Jarrow's glass bottle and cap better over Source Naturals bottle caps/neck. I like screw caps/necks like Jarrow or Doctor's Best bottles. I use B-12 with Country Life coenzyme B complex. I also use Natural Factors B-12.

Excellent to help with energy levels

Posted by Reviewer1310692 on Mar 03, 2008

I started taking this about 8 months or so ago. I have allowed myself to run out only once. I can definitely tell when I have not been taking it, as I am not able to run on less sleep or go full throttle if I have not been taking it. I did research on the best sources of B-12 and this one contains both of the two recommended, most usable sources. I have recommended this to others as well. I am placing another order right now for this. It is also one of the most reasonably priced and dissolves quite quickly. I am a firm believer in this product!

Seems good

Posted by Reviewer1099448 on Mar 29, 2008

I needed more B-12, and this sublingual variety seems to be helpful. And, it is pleasant to take.

Works great

Posted by Reviewer1949759 on Dec 17, 2007

I have been taking these for 2 months now. I have a history of depression, and since I have been taking these, I have not had a bout. I take Nexium for acid reflux and it depletes the Vitamin B in your system. This has been a great supplement for energy and mood!
