Our assessment

The evidence shows that this product's key ingredient, Calcium, has a well-established role in bone health, but you should be aware of specific risks and medication interactions. Our assessment is that while Calcium is essential for your child, the form and dose in this supplement must be evaluated against your child's total daily intake from food and other sources.

How it works

Calcium is a critical mineral for your child's growing body. Think of it as the primary building block for strong bones and teeth, supporting bone density and mineral deposition [NIH ODS]. It also plays a key role in neuromuscular relaxation, helping muscles relax and nerves signal properly after activity [NIH ODS].

Safety profile

Data not available for this specific product's adverse event profile. However, for the ingredient Calcium, high intakes from supplements might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. The FDA has received a total of 592,059 adverse event reports across all supplement categories, but this number is not specific to this product [FDA data].

Our recommendation

We recommend you first check your child's total daily calcium intake from food and other supplements before adding this product. Calcium can reduce the absorption of important medications like tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If your child takes any of these, separate the supplement from the medication by at least two hours. For most children, getting calcium from food is the safest approach, and this supplement should only be used to fill a documented gap in their diet.
