Our assessment
The evidence shows that while Calcium is essential for bone health, the specific product "Douglas Laboratories Methyl B12 Plus" cannot be assessed for its calcium content because data on its ingredients is not available. For calcium as a standalone mineral, the data confirms its role in bone mineralization and neuromuscular function [NIH ODS]. However, you should be aware of significant risks, including potential links to heart disease and prostate cancer with high intakes [NIH ODS].
How it works
Think of calcium as a key structural component for your skeleton. It supports bone density through mineralization and also helps your muscles relax and nerves signal properly [NIH ODS]. Without adequate calcium, your body may leach it from your bones, weakening them over time.
Safety profile
FDA received a total of 592,059 adverse event reports for all dietary supplements combined. For calcium specifically, high intakes can lead to serious side effects including 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for this specific product's calcium content. If you are considering a calcium supplement, do not exceed the Tolerable Upper Intake Level without medical supervision, and always take calcium supplements separately from your thyroid or antibiotic medications [NIH ODS]. Your best first step is to discuss your dietary calcium intake with your healthcare provider.
