Our assessment
The evidence shows that this product supplies vitamin B12, not calcium. While you asked about calcium, the data provided does not include specific information on Jarrow Formulas Methyl B-12 Lemon Flavor 1000 mcg. For calcium, the evidence shows it is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Data not available for this specific product’s efficacy or benefits.
How it works
Think of calcium as a structural building block for your bones and a signal regulator for your nerves. It supports bone density and mineral deposition, and helps your muscles relax and nerves signal properly [NIH ODS]. You need adequate vitamin D to absorb calcium effectively, though that data is not provided here.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high levels 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 bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for this specific product. For calcium, get your intake from food first. If you use supplements, keep total calcium from all sources below 2,000–2,500 mg daily from food and supplements combined [NIH ODS]. Take calcium supplements with food and separate from thyroid or antibiotic medications by at least 2 hours [NIH ODS].
