Why Supplement with B-12?
A common trait in heart disease, Alzheimer’s, and osteoporosis patients is B-12 deficiency. People suffering from depression also have low B-12 levels. Your body cannot make B-12, so it needs this vitamin from your diet. When you eat foods rich in B-12, like eggs, milk, meat, fish, cheese, and poultry, the cells of your stomach releases a substance known as intrinsic factor. This transports B-12 safely through digestion and preps it for absorption. If this factor gets out of whack, you don’t get enough B-12. Low stomach acidity and damage to cells in the stomach reduces the amount of intrinsic factor you make, and, the older you get, the less intrinsic factor is produced. [1]
Sublingual B-12 = Better Absorption
Vitamin B-12 supplements come as tablets, sublingual tablets, or liquids. Except in extreme cases of deficiency, shots of B-12 aren’t overly necessary. [2] The tablets depend on digestive function for the most part, which is one reason they’re not as effective. The benefit of sublingual vitamin B-12 is that you don’t need to rely on digestion. Here’s how Sublingual B-12 works: sublingual forms of B-12–whether in liquid or tablet form–are placed under the tongue. You hold it in your mouth to allow the B-12 to absorb directly into your blood through the membrane in your mouth. This bypasses the digestive process and the need for intrinsic factor.
Advantages of Sublingual B-12
Sublingual B-12 circumvents digestion so you can get a lot of value out of it regardless of the state of your stomach or intrinsic factor production. Most sublingual vitamin B-12 formulas have the same types of B-12 that your body prefers — methylcobalamin and adenosylcobalamin. Other B-12 supplements may contain B-12 in the form of cyanocobalamin, which require your liver remove the cyanide (cyano-) molecule before it can create a natural methylcobalamin form. Vitamin B-12 Tri-Blend is a vegan friendly B-12 supplement that’s a great alternative to sublingual B-12 supplements and it contains methylcobalamin and adenosylcobalmin, the two most bioactive forms of B-12.
