Side Effects of Vitamin B12 Sublingual 2500 mg

Unlike some dietary supplements, Vitamin B12 has a considerable amount of research that supports its impact on human physiology. Vitamin B12 is well accepted by both the allopathic and naturopathic communities as a micro-nutrient capable of supporting a focused mind and improved metabolism of carbohydrates, fats and proteins. Daily sublingual ingestion of Vitamin B12 at 2,500 mcg is often considered a therapeutic level of the supplement and consumers should avoid such a high amount without consulting a practitioner.

  1. The Facts

    • Vitamin B12 is produced in the intestinal tract by healthy micro-flora but usually in insufficient amounts to maintain optimal health. Therefore, many people supplement their intake with a dietary supplement that uses a sublingual delivery method.

    History

    • Vitamin B12 is delivered orally, by injection or through tablets that release the vitamin for sublingual absorption. It plays a vital role in digestion and a lack of the nutrient is associated with pernicious anemia.

    Significance

    • According to the National Institutes of Health's Office of Dietary Supplements (ODS) the DRI (Dietary Reference Intake) for B12 is 2.4 mcg for adults. A supplement that provides more than 100 times the DRI can appear overly aggressive.

    Function

    • Also known as cyanocobalamin, B12 is a coenzyme, meaning it is required as part of an enzymatic process. It is an essential nutrient despite the fact that it can be created in the bowel.

    Circumstances

    • Individuals needing to supplement their diet with Vitamin B12 will often use supplements in the 1,000-to-2,500 mcg range to offset the poor absorption rates of dietary supplements and to offset the existing deficiency.

    Side Effects

    • The body is extremely inefficient when it comes to absorbing large amounts of nutrients. Side effects from Vitamin B12 delivered sublingually are rare and are most-often related to an allergy associated with another ingredient in the dietary supplement.

    Warning

    • All consumers considering supplementing their diets should speak to their doctor about possible complications due to existing conditions, prescription medication or other supplements.
