The Vitamin Shoppe Calcium Citrate Plus Magnesium
Brand: The Vitamin Shoppe · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: This supplement provides calcium in the citrate form, which is generally well-absorbed, alongside magnesium for added support. However, the evidence shows you need to be very careful with dosing. The data provided does not include a specific dose per serving, so we cannot confirm if this product meets your daily needs without that information. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Calcium acts as a master regulator for your bones by supporting bone mineralization and density [NIH ODS]. It also plays a key role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS]. Think of it as the building block your body relies on for structural strength and daily function.
Safety profile
The FDA has received a total of 592,059 adverse event reports for products in this category [FDA data]. Specific side effects from high calcium levels include constipation, nausea, weight loss, extreme tiredness, poor muscle tone, poor kidney function, 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
Our recommendation: Before taking this supplement, check the label for the exact amount of calcium per serving. If you are taking any prescription medications, take this supplement at least two hours apart from them to avoid absorption issues [NIH ODS]. Because high calcium intakes carry significant risks, do not exceed the recommended daily allowance without your doctor’s guidance. Data not available for the specific magnesium dose or its interactions in this product.
