CVS Health B12 1000 mcg

Brand: CVS Health · Form: TABLET [E0155] On Market

Our assessment

The evidence shows that CVS Health B12 1000 mcg is a straightforward supplement for supporting vitamin B12 levels. However, based on the data provided, the active ingredient is not vitamin B12 — it is calcium. This means the product label and the available safety data do not align. For a true B12 supplement, you should verify the label lists cyanocobalamin or methylcobalamin. Data on B12 itself is not available in the provided information [Data not available].

How it works

Since the ingredient data available is for calcium, not B12, we can only speak to calcium's role. Calcium supports bone mineralization, helping maintain bone density, and it aids neuromuscular relaxation by supporting proper muscle and nerve signaling [NIH ODS]. For B12 specifically, it typically supports nerve health and red blood cell formation, but that information is not present in the provided data.

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer. High levels in the blood can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Because the provided data does not confirm that this product contains vitamin B12, I cannot recommend it for B12 supplementation based on the information given. If you need a B12 supplement, choose a product where the label clearly lists "cyanocobalamin" or "methylcobalamin" as the active ingredient. If you are taking this for bone health as a calcium source, be aware of the potential risks and medication interactions listed above [NIH ODS]. Always consult your healthcare provider before starting a new supplement.
