Our assessment
Our assessment: The evidence for this product is limited to the ingredient calcium. While calcium is essential for bone health, you should be aware that high intakes may carry significant risks. Data not available for the specific brand or glutamine content.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, as well as neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as a key structural component for your skeleton and a critical signal for your muscles to relax properly.
Safety profile
FDA received 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from very high levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should get calcium from food sources whenever possible. If you choose a supplement, do not exceed the RDA without medical supervision. Monitor for side effects and discuss any medication interactions with your doctor. Data not available for the specific glutamine content or brand.
