KR Calcium Citrate & Vitamin D3 Chewable Tablets
Brand: KR · Form: TABLET [E0155] On Market
Our assessment
Our assessment: The evidence shows that KR Calcium Citrate & Vitamin D3 Chewable Tablets can be an effective way to meet your calcium needs, but you must be aware of the potential risks. Calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS]. However, high intakes might increase the risk of heart disease and prostate cancer, so it is crucial to stay within recommended limits [NIH ODS].
How it works
Think of calcium as a master builder for your bones. It supports bone density and mineral deposition, helping to keep your skeleton strong [NIH ODS]. At the same time, it acts as a nerve relaxant, supporting proper muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for products like this. High levels of calcium in your 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] [FDA data]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not exceed the recommended daily allowance for calcium without a doctor's supervision. Because of the risk of interactions, take this supplement at least two hours apart from any thyroid medication or antibiotics. Start with one chewable tablet daily and monitor for side effects like constipation or nausea [NIH ODS].
