Our assessment
The evidence shows that Pure Encapsulations B12 Liquid is a supplement designed to deliver vitamin B12, but our assessment is based on the ingredient data provided for calcium, which is listed in the product's ingredient profile. For the specific benefits of vitamin B12, data is not available in the provided information. Based on the calcium data, this product may support bone density and mineral deposition as well as muscle relaxation and nerve signaling [NIH ODS]. You should be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
How it works
Think of the calcium in this formulation as a structural support — it contributes to bone mineralization by helping deposit minerals into your bone matrix, and it also plays a role in neuromuscular relaxation, which supports proper muscle function and nerve signaling [NIH ODS]. This mechanism is critical for maintaining strong bones and healthy muscle contractions throughout your body.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories, though specific report counts for this product are not available. Some research suggests that 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].
Our recommendation
Our recommendation is to use this product with caution if you take any medications that interact with calcium, particularly bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin [NIH ODS]. You should avoid exceeding recommended doses to prevent the risks associated with high calcium levels in the blood and urine [NIH ODS]. For specific guidance on vitamin B12 dosing and benefits, data is not available in the provided information, so please consult your healthcare provider for personalized advice.
