PureBulk.com Vitamin B12 01% (Cyanocobalamin)

Our assessment

The evidence shows that this product, which is a cyanocobalamin form of vitamin B12, is a standard and widely used supplement for addressing deficiencies. However, based on the data provided, the ingredient information is incomplete, and the health claims and safety profile for this specific product rely on general nutrient data. Our assessment is that while vitamin B12 is essential, you should verify the specific dosage on the label, as the data here does not include a recommended daily allowance or specific study results for this product.

How it works

Vitamin B12 (cyanocobalamin) is a water-soluble vitamin that acts as a cofactor for two critical enzymatic reactions in your body. It is essential for DNA synthesis, red blood cell formation, and the maintenance of your nervous system. The body converts cyanocobalamin into the active forms, methylcobalamin and adenosylcobalamin, which support these vital processes [NIH ODS]. The data does not provide a specific mechanism for this brand, but the general function of B12 is well-established.

Safety profile

Based on FDA adverse event data, there have been 592,059 total reports for all supplement products, but this number is not specific to vitamin B12 or this brand [FDA data]. The provided NIH ODS data on safety pertains to calcium, not vitamin B12, so specific side effects for this product are not available. Data not available for side-effect report counts specific to vitamin B12 from the FDA data provided. You should always consult a healthcare provider before starting a new supplement, especially if you have a medical condition.

Our recommendation

Our recommendation is to confirm the specific dosage of cyanocobalamin per serving on the product label, as this data set does not list it. For most adults, a standard daily dose is between 2.4 mcg and 1,000 mcg, depending on your needs. If you are using this for a known deficiency, follow your healthcare provider's guidance. Because the data here is incomplete regarding interactions and side effects for this specific product, consult your pharmacist or doctor, particularly if you take medications for acid reflux or diabetes, as these can affect B12 absorption [NIH ODS].

Supplement labels contain several key sections regulated by the FDA:

• Serving Size — The recommended amount per dose. Always check this — some products require multiple capsules per serving.
• Amount Per Serving — Shows the quantity of each nutrient in the product, typically in IU (International Units), mg (milligrams), or mcg (micrograms).
• % Daily Value (%DV) — Indicates how much a nutrient in a serving contributes to a daily diet. 5% DV or less is low; 20% DV or more is high.
• Other Ingredients — Lists inactive ingredients like fillers, binders, and capsule materials (e.g., gelatin, cellulose, magnesium stearate).
• Suggested Use — The manufacturer's recommended directions for taking the supplement, including timing and dosage.
