NOW Clinical Probiotic Immune
Brand: NOW · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is an essential mineral, but the specific product NOW Clinical Probiotic Immune does not list calcium as an ingredient. For calcium itself, the data confirms it is critical for bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high intakes may carry significant risks.
How it works
Think of calcium as a building block for your bones and a signal regulator for your nerves and muscles. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. Very 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Since calcium is not listed as an ingredient in NOW Clinical Probiotic Immune, data on its dosage in this product is not available. For calcium supplements in general, start by assessing your dietary intake. Be mindful of the risks of high calcium levels and check for potential interactions with your medications [NIH ODS].
