Sunmark Vitamin B12 500 mcg
Brand: Sunmark · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sunmark Vitamin B12 500 mcg is a straightforward supplement for addressing vitamin B12 needs. However, the data provided contains information on calcium, not vitamin B12. For vitamin B12-specific effects, we must rely on general principles: B12 is essential for nerve function and red blood cell formation. For this specific product, specific study data is not available in the provided materials.
How it works
While data for this exact product is limited, calcium (the only ingredient with data) supports bone mineralization and neuromuscular relaxation [NIH ODS]. For vitamin B12, it typically acts as a cofactor for DNA synthesis and energy metabolism. You should know that B12 from supplements is often well-absorbed, especially in sublingual forms, but specific mechanism data for this product is not available.
Safety profile
The FDA received 592,059 total adverse event reports across all supplements, though specific reports for this product are not isolated in the data [FDA data]. For calcium (the only ingredient with safety data), high intakes may increase risk of heart disease and prostate cancer, and can cause constipation, nausea, weight loss, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications like bisphosphonates and tetracycline antibiotics [NIH ODS]. For vitamin B12, side effect data is not available in the provided information.
Our recommendation
Our assessment: You can consider this supplement if you have a diagnosed B12 deficiency or follow a restricted diet. However, the data provided does not include specific B12 study findings or adverse event reports for this product. We recommend consulting your healthcare provider before starting, especially if you take medications for heartburn or diabetes, as data on interactions is not available. Start with one 500 mcg tablet daily as directed on the label. Data not available for specific benefits beyond general B12 needs.
