Sunmark Vitamin B12 100 mcg
Brand: Sunmark · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sunmark Vitamin B12 100 mcg is a straightforward supplement for supporting energy and nerve function. However, the critical data limitation here is that the product label lists "Calcium" as the primary ingredient data, not Vitamin B12. Based on the data provided, we cannot confirm the specific benefits or dosing for Vitamin B12. For the ingredient listed in the data—Calcium—our assessment is that it plays a key role in bone health and muscle function, but you must be cautious with dosing to avoid risks [NIH ODS].
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also helps your muscles relax and your nerves signal properly after contraction [NIH ODS]. For the intended Vitamin B12 product, data on its specific mechanism is not available in the provided information.
Safety profile
Data not available for Vitamin B12 side effects from this specific product. For the calcium data provided, the FDA received 592,059 total adverse event reports across all supplements. High calcium intakes may increase the risk of heart disease and prostate cancer, and can cause poor muscle tone, nausea, constipation, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS] [FDA data].
Our recommendation
We cannot recommend Sunmark Vitamin B12 100 mcg based on the provided data, as the ingredient information is inconsistent. If you are seeking a calcium supplement, be aware that it can reduce absorption of medications like bisphosphonates and levothyroxine, so take it at a separate time [NIH ODS]. Always consult your pharmacist or doctor before starting any new supplement, especially if you take prescription medications. Data for a Vitamin B12 recommendation is not available.
