Our assessment
The evidence shows that Sundown Naturals High Potency B12 1000 mcg Time Release is a straightforward supplement for addressing vitamin B12 needs. However, because the ingredient listed in the data is calcium, our assessment is based on that ingredient. For calcium, we have solid data on its role in bone health, but you should be aware of specific risks and medication interactions before adding it to your routine [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is critical for preventing fractures as you age. Calcium also acts as a nerve and muscle regulator, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
Safety data for this product is limited. The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Extremely high levels of calcium in your 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].
Our recommendation
Data not available on the appropriate dosage for this specific product. Before taking this supplement, check with your healthcare provider, especially if you take medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, as calcium can reduce their absorption [NIH ODS]. For most people, getting calcium from food sources is preferable to supplements [NIH ODS].
