Our assessment
The evidence shows that calcium is a critical mineral for bone health, but it requires careful dosing and timing to be safe and effective for you. For a liquid B12 product, our assessment is that the data provided does not include specific information on vitamin B12 itself or this formulation. Therefore, our analysis focuses on calcium as the only ingredient with data available [NIH ODS].
How it works
Think of calcium as a structural builder and signal regulator for your body. It supports bone mineralization by helping deposit minerals into your skeleton, and it aids neuromuscular relaxation by allowing your muscles and nerves to signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. Specific to calcium, high intakes may increase the risk of heart disease and prostate cancer. Excessive levels in the blood and urine 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 [FDA data] [NIH ODS].
Our recommendation
You should be cautious with calcium supplementation. It can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data for the specific PureFormulas Liquid B12 product is not available. Consult your healthcare provider before starting any new supplement, especially if you take prescription medications or have a history of kidney or heart conditions.
