MyBite Vitamins Good Bones Calcium

Our assessment

The evidence shows calcium is essential for bone health, but the data on supplementation requires careful consideration. MyBite Vitamins Good Bones Calcium provides this mineral, which supports bone density and mineralization [NIH ODS]. However, you should be aware that high calcium intakes from supplements might increase the risk of heart disease and prostate cancer, according to some research [NIH ODS]. We recommend evaluating your dietary calcium intake before adding this supplement.

How it works

Think of calcium as the structural building block for your skeleton. It works through bone mineralization to support bone density and mineral deposition [NIH ODS]. Beyond your bones, calcium also supports neuromuscular relaxation, meaning it helps your muscles relax and nerves signal properly [NIH ODS]. Your body cannot produce calcium, so you must get it from food or supplements.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high levels 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].

Data not available on total report count specific to this product.

Our recommendation

Start by assessing your total calcium intake from food sources. Do not exceed the Tolerable Upper Intake Level without medical supervision. If you take this supplement, take it separately from medications like thyroid hormone or antibiotics by at least two hours [NIH ODS]. Consult your healthcare provider to determine if calcium supplementation is right for you, especially given potential heart risks [NIH ODS].
