Our assessment
The evidence shows that calcium is essential for bone health, but the data on high intake requires caution. For the Isotonix Calcium Plus product, our assessment is based on the calcium content and its known effects. You should be aware that while calcium supports bone mineralization, some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
How it works
Think of calcium as a key structural component for your bones and a critical signaling molecule for your nerves and muscles. It supports bone density and mineral deposition, and it also helps with neuromuscular relaxation and nerve signaling [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all products. 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by assessing your total calcium intake from food and other supplements. If you choose to use this product, take it at a separate time from medications like thyroid hormone or antibiotics to avoid absorption issues [NIH ODS]. We recommend consulting your healthcare provider to determine if you need a supplement, as getting calcium from food sources is generally preferred. Specific data on the Isotonix Calcium Plus formula beyond its calcium content is not available in the provided data.
