DaVinci Laboratories Of Vermont Sublingual B12-MC

Our assessment

The evidence shows that this product contains Calcium, a mineral essential for bone health and muscle function [NIH ODS]. However, we must be clear: the specific brand and formulation of this product are not detailed in the available data, so our assessment focuses solely on the active ingredient, Calcium. For a general audience, getting enough calcium through diet is often preferred, but supplements can help fill gaps when needed [NIH ODS].

How it works

Think of calcium as a master builder and signal messenger for your body. It supports bone mineralization, helping to maintain strong bone density [NIH ODS]. It also plays a critical role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly after they've been activated [NIH ODS].

Safety profile

Data not available for this specific product's adverse events. However, for the ingredient calcium, the FDA has received a total of 592,059 adverse event reports across all supplements. Regarding safety, 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Before starting this supplement, consult your healthcare provider to determine if you need additional calcium. If you do, aim for a dose that brings your total daily intake (from food and supplements) to the recommended level, typically 1,000 to 1,200 mg for most adults [NIH ODS]. Be mindful of the interactions with other medications you may be taking. Because the specific product label data is not provided, we cannot confirm its quality or dosage, so a trusted, third-party tested brand is your best choice [NIH ODS].
