The Vitamin Shoppe Active-C 1000 mg with Bioflavonoids
Brand: The Vitamin Shoppe · Form: TABLET [E0155]
Our assessment
The evidence shows that The Vitamin Shoppe Active-C 1000 mg with Bioflavonoids is a vitamin C supplement. However, the critical ingredient supported by the data provided is calcium. Our assessment: if you are taking this product for its calcium content, you should be aware of the specific risks and interactions. The FDA has received a total of 592,059 adverse event reports for all dietary supplements, though this number is not specific to this product [FDA data].
How it works
Calcium plays a key role in bone mineralization, helping to support bone density and mineral deposition. It also supports neuromuscular relaxation and nerve signaling throughout your body [NIH ODS]. This makes it essential for maintaining strong bones and proper muscle function.
Safety profile
Safety data for calcium is mixed. Some research suggests that high calcium 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for specific dosing of this product. We recommend you check the label for the exact amount of calcium and vitamin C per serving. If you are taking medications for osteoporosis, thyroid conditions, or infections, take this supplement at a different time of day than those medications to avoid absorption issues [NIH ODS]. Start with the lowest effective dose and do not exceed the label's recommended serving.
