How it works

Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it also plays a critical role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key mineral that helps your muscles relax after contracting and keeps your bones strong.

Data not available for this specific product's side effects. However, for the ingredient calcium, the FDA has received 592,059 total adverse event reports across all supplements.

Our recommendation

Do not take this supplement until you have reviewed the label for the exact calcium content. If you choose a calcium supplement, remember it can reduce the absorption of medications like tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Talk to your doctor or pharmacist before starting, especially if you take any prescription medications.
