Our assessment
The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function [NIH ODS]. However, data for vitamin D-3 specifically is not available in the provided information. Our assessment is that while calcium is well-supported for its role in bone mineralization, you should be aware of potential risks and drug interactions associated with calcium supplementation [NIH ODS].
How it works
Think of calcium as a building block and a messenger. It supports bone density and mineral deposition, and it also helps your muscles relax and your nerves send signals properly [NIH ODS]. This dual role makes it critical for both your skeletal structure and your daily physical function.
Safety profile
The FDA received 592,059 total adverse event reports for all products in the database, but specific report counts for this supplement are not available. Regarding calcium, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for a specific vitamin D-3 dosage. For calcium, be cautious about high intakes and always discuss supplementation with your healthcare provider, especially if you take any of the medications listed above [NIH ODS]. We recommend obtaining calcium from food sources first and only supplementing under medical supervision to avoid potential risks [NIH ODS].
