The inactive ingredients include mannitol, croscarmellose sodium, magnesium stearate, natural cherry flavor, and Farm Fresh Factors.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Vitamin B12 support and red blood cell production.
  • We looked for evidence on: Vitamin B12 deficiency, Fatigue, Peripheral neuropathy, Chemotherapy-induced peripheral neuropathy, Diabetic neuropathy, Hyperhomocysteinemia — and 4 related terms.
  • The strongest evidence on file: Vitamin B12 is rated "Effective" for Vitamin B12 deficiency (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Possibly Effective" for Hyperhomocysteinemia.
  • Also on file: Vitamin B12 is rated "Possibly Ineffective" for Age-related cognitive decline.

Vitamin B12 supplementation is effective for treating B12 deficiency and Imerslund-Grasbeck disease (a rare genetic disorder affecting B12 absorption). It's likely effective for cyanide poisoning.

The evidence is less complete but possibly effective for canker sores and postherpetic neuralgia (nerve pain after shingles).

The evidence, ingredient by ingredient Vitamin B12

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Vitamin B12 is very well tolerated when taken by mouth. Your body removes excess B12 in urine, so there's no established upper limit.

Serious side effects are rare; most people experience either no effects or mild ones. Allergic reactions such as rash or itching are uncommon but have been reported in the literature, and one case of contact dermatitis was linked to cobalt sensitivity.

During pregnancy and breastfeeding, B12 is considered safe at recommended amounts and is actually needed — follow your provider's guidance on dosing.

Side effects, ingredient by ingredient Vitamin B12

Formula

Vitamin B12 helps produce red blood cells, maintain good health, and prevent B12 deficiency states such as pernicious anemia. Methylcobalamin and dibencozide are coenzyme forms of vitamin B12 whereas cyanocobalamin must be converted to its metabolically active coenzyme form in a two-step process. Taking methylcobalamin and/or dibencozide allows for greater absorption and bioavailability than non-coenzyme forms.

The most metabolically active form

This product has passed the most rigorous testing in the world for contaminants and quality. isura.com

What does coenzymated mean? In order for B vitamins to be utilized effectively by the body, they must be converted into their metabolically active coenzyme forms. For example, the two coenzyme form of vitamin B12 are methylcobalamin and dibencozide. A coenzyme is a naturally occurring compound that partners with specific enzymes in order to help promote a number of beneficial metabolic reactions in the body. Without the coenzyme, the enzyme cannot promote the biochemical reaction that is responsible for our survival. This dual cooperation between coenzyme and enzyme is a process called coenzymated. Taking B vitamins already in their coenzymated forms allows the body to use them directly. Thus, the amount that is needed by the body is less in order to achieve the same benefits. Biocoenzymated takes it one step further.

The synergy between the phytochemicals found in these plant extracts and the coenzyme B vitamin optimizes absorption. The results? Biocoenzymated delivers the most metabolically active nutrients to your cells to utilize most effectively. Feel the difference.

Does this B12 supplement work?
Yes, it's effective for B12 deficiency and a rare absorption disorder called Imerslund-Grasbeck disease. It's likely effective for cyanide poisoning and possibly effective for canker sores and nerve pain after shingles. How well it works for you depends on why your B12 is low in the first place.
