Our assessment
The evidence shows that calcium is a critical mineral for your bone health, but it requires careful management. Based on the data, we advise you to approach calcium supplementation with a clear plan and awareness of its potential risks. The data for this product is limited, so we are providing guidance on the primary ingredient, calcium [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, which is essential for keeping your bones strong. Calcium also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you get your calcium primarily from food sources and only supplement if advised by your healthcare provider. Because calcium interacts with many common medications, you must take it at a different time from those drugs. Data on the specific benefits and risks of this Genestra product is not available, so we cannot make a specific recommendation for it. Always consult your doctor before starting a new supplement, especially one containing calcium [NIH ODS].
