ProCaps Laboratories Vitamin B12-100
Brand: ProCaps Laboratories · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains calcium, not vitamin B12 as the name suggests. Based on the data provided, we cannot assess the benefits of vitamin B12 from this supplement. For the calcium present, our assessment is that it supports bone health and nerve function, but you must be cautious with dosing, as high intakes carry significant risks [NIH ODS].
How it works
Think of calcium as a structural builder and signal messenger. It supports bone density and mineral deposition, which is critical for keeping your skeleton strong. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. Specific side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease. High levels can also cause poor muscle tone, poor kidney function, and low phosphate levels [FDA data] [NIH ODS]. Calcium supplements may reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Data not available for side effects specific to vitamin B12 from this product.
Our recommendation
We recommend you verify the label of this product carefully, as the name suggests vitamin B12 but the data provided shows it contains calcium. If you require vitamin B12, data for that ingredient is not available here. If you are taking this for calcium, start with a low dose and take it with food. Be aware of the serious risks of high calcium intake and always check with your doctor about potential interactions with your medications [NIH ODS] [FDA data].
