Our assessment
The evidence shows that this product contains calcium, which is essential for bone health and nerve function [NIH ODS]. However, the data does not provide specific details about the exact formulation or potency of the NOW Co-Enzyme B-Complex product itself. Our assessment is that while calcium is a well-studied mineral, you should be cautious about supplementing without knowing your individual needs, as high intakes carry significant risks [NIH ODS].
How it works
Calcium plays a critical role in bone mineralization, helping to build and maintain strong bones by supporting density and mineral deposition [NIH ODS]. It also acts as a master regulator for your nervous system, supporting neuromuscular relaxation and proper nerve signaling [NIH ODS]. This means it helps your muscles relax after contracting and ensures your nerves send messages correctly throughout your body.
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 [FDA data]. The data shows that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium can include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. High levels can also cause poor muscle tone and poor kidney function [NIH ODS].
Our recommendation
Data not available for a specific dosage recommendation as the product's label details were not provided. Before taking this supplement, you should check your total calcium intake from food and other supplements. If you take this product, be aware it can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, levothyroxine, and phenytoin [NIH ODS]. Separate calcium supplements from these medications by at least 2 hours. We recommend consulting your healthcare provider to determine if this supplement is right for you.
