Jarrow Formulas Methyl B-12 Cherry Flavor 5000 mcg
Brand: Jarrow Formulas · Form: LOZENGE [E0174]
Our assessment
The evidence shows that Jarrow Formulas Methyl B-12 Cherry Flavor 5000 mcg provides a high dose of vitamin B12. However, based on the data provided, the supplement contains **Calcium** as a key ingredient, not vitamin B12. Data for the specific B12 content and its effects are not available in the provided information. Our assessment must rely on the available data for the identified ingredient.
How it works
Think of calcium as a structural foundation — it supports bone density and mineral deposition, and also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. The specific mechanism of the "Methyl B-12" component is not detailed in the provided data.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but a specific report count for this product is not available. Based on the ingredient data, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should be cautious with this product. The label indicates a high-dose B12 supplement, but the available data only describes a calcium ingredient. Before use, verify the full ingredient list on the label. If you are taking any medications, especially those listed above (bisphosphonates, certain antibiotics, or thyroid medication), consult your healthcare provider due to potential calcium interactions [NIH ODS]. Data not available for the specific B12 content or its effects, so we cannot recommend this product based on the provided information.
