Our assessment
The evidence shows that Sundown Naturals High Potency B12 1500 mcg Time Released is a supplement, but the data provided only covers the ingredient calcium, not B12. For calcium, the data indicates it supports bone mineralization and nerve signaling [NIH ODS]. However, we cannot assess the B12 content or its specific benefits from the available information.
How it works
Think of calcium as a structural and signaling agent — it supports bone density and mineral deposition, and also helps with muscle relaxation and nerve signaling [NIH ODS]. For the B12 in this product, specific mechanisms are not available in the data provided.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements in this category [FDA data]. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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]. Side effects for B12 specifically are not available in the data provided.
Our recommendation
Data not available to make a specific recommendation for Sundown Naturals High Potency B12 1500 mcg Time Released. For calcium, be aware that it can reduce absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider before starting this supplement, as we lack specific efficacy and safety data for the B12 component.
