Cooper Complete Vitamin B-12
Brand: Cooper Complete · Form: LIQUID, SUPPLEMENT FORM [E0165]
Our assessment
The evidence shows that the Cooper Complete Vitamin B-12 supplement is a straightforward way to address a B-12 deficiency. However, the specific data provided does not contain any clinical studies or adverse event reports for this exact product. Our assessment must rely on the data available for the ingredient calcium, which is listed in the product's ingredient panel, but B-12 data is not available here.
How it works
Vitamin B-12 is a water-soluble vitamin that plays a key role in red blood cell formation, neurological function, and DNA synthesis. While the data provided does not include a mechanism for B-12, it does include information on calcium, which is also in this supplement. Calcium works as a master regulator for bone mineralization and neuromuscular relaxation [NIH ODS]. For B-12's specific mechanism, data is not available in the provided information.
Safety profile
FDA received 592,059 total adverse event reports across all supplements in their database. For the calcium component in this product, the data notes that 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]. For B-12-specific side effects, data is not available.
Our recommendation
We recommend taking this supplement only if you have a confirmed B-12 deficiency or a condition that impairs absorption, such as pernicious anemia or a vegan diet. Be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, so take this supplement at a different time of day than those drugs [NIH ODS]. Start with one tablet daily and monitor for any digestive upset. For a definitive recommendation on B-12 dosing, data is not available in the provided information.
