Product Overview


  • Vitamin Supplement
  • Vegetarian

Vitamin B-12 is an essential nutrient, involved in protein formation. The coenzyme form of vitamin B-12 is necessary for carbohydrate, protein and fat metabolism, as well as for proper DNA replication. Source Naturals Vitamin B-12 tablets are formulated to dissolve easily under the tongue for more direct absorption into the bloodstream. This minimizes destruction of the vitamin B-12 by stomach acids.

Suggested Use

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

Other Ingredients

Sorbitol, mannitol, natural raspberry flavor, natural peach flavor, and magnesium stearate.

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


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

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

Not What I Expected

Posted by 4933326074469546264 on Jun 16, 2016

While this product is likely good quality; I expected it would dissolve a lot faster than it does. Perhaps that is part of the efficacy of the product. The product description doesn't go into detail further than it being sublingual. I've taken sublingual B-12 for awhile and really prefer those that dissolve quickly. I will take this after I take my other meds and vitamins until I have used it up and will be inclined to find another sublingual B-12 that will dissolve faster. Just my personal preference.
