Our assessment
The evidence shows that this product contains calcium, which is a mineral essential for bone health and muscle function. However, the data on calcium requires careful consideration, as both dosage and safety are nuanced [NIH ODS].
How it works
Think of calcium as a key structural component for your body. It supports bone mineralization and density, and it plays a critical role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after activity [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific data for this exact product is not available.

High blood and urine levels of calcium can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS]. Additionally, calcium can reduce absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
