Brand: Sundown Naturalist · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sundown Naturalist B12 500 mcg is a standard-dose supplement. Our assessment is that for many adults, a daily intake of 500 mcg of vitamin B12 is well above the typical recommended dietary allowance, which is 2.4 mcg for most adults [NIH ODS]. This high dose is often used to correct deficiencies or support energy levels. However, we must be clear: the data provided here is for calcium, not for vitamin B12. Therefore, all specific health claims regarding B12's mechanisms, interactions, and safety cannot be confirmed from this dataset.
How it works
Based on the data provided, the ingredient calcium works as a master regulator for bone mineralization, supporting bone density and mineral deposition. It also plays a role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. Since the product contains B12, not calcium, these mechanisms do not apply to your supplement. Data on how B12 works is not available in this dataset.
Safety profile
Data not available for the specific side effects of vitamin B12 from this dataset. The FDA adverse event database shows a total of 592,059 reports across all supplements, but specific report counts for this product or ingredient are not provided [FDA data]. For calcium, the data notes that high intakes may increase the risk of heart disease and prostate cancer, and can cause poor muscle tone, constipation, nausea, weight loss, extreme tiredness, and abnormal heart rhythms [NIH ODS]. This information is not relevant to your B12 supplement.
Our recommendation
Our recommendation is to consult your healthcare provider before starting any new supplement, including this B12 product. Because the provided data only covers calcium, we cannot confirm any specific benefits or risks for B12. The 500 mcg dose is high, and while often considered safe, your individual needs should be assessed. For evidence-based information on vitamin B12, we recommend reviewing the NIH Office of Dietary Supplements fact sheet directly [NIH ODS].
