Our assessment
The evidence shows that Vitamin Shoppe Active-C 1000 mg contains calcium, a mineral essential for bone health. Our assessment is that this product can be a useful supplement for supporting your bone density, but you need to be aware of specific risks and interactions before taking it [NIH ODS].
How it works
Think of calcium as the building block for your skeleton. It supports bone mineralization and density by helping deposit minerals into your bone tissue. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
Safety data comes from the NIH and FDA. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. The FDA received a total of 592,059 adverse event reports for all products, but specific report counts for this supplement are not available [FDA data].
Our recommendation
Start by evaluating your total daily calcium intake from food and other supplements. This product can interact with medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, reducing their absorption [NIH ODS]. Do not exceed the tolerable upper intake level without medical supervision. Data not available on the exact dose per serving from the label provided, so check the label carefully. Our recommendation: discuss your calcium needs with your healthcare provider before starting, especially if you have kidney concerns or take any of the listed medications [NIH ODS].
