Sundown B12 500 mcg
Brand: Sundown · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Sundown B12 500 mcg is a straightforward supplement, but the data we have is primarily about calcium, not B12. For calcium, our assessment is that it is critical for bone health, but you must be careful with dosing and timing. Data on the specific ingredient in your product, B12, is not available from the provided sources.
How it works
Calcium works as a master regulator for your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the material that keeps your skeleton strong and your nervous system running smoothly.
Safety profile
From the FDA data, there are a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
For this Sundown B12 product, data on its specific benefits and risks is not available. If you are taking calcium separately, our recommendation is to take it with food and separate it from other medications by at least two hours to avoid absorption issues [NIH ODS]. For the B12 in this product, you should consult your healthcare provider to determine if a 500 mcg dose is right for you, as specific evidence for this product is not provided.
