Carlson L-Glutamine Amino Acid Powder
Brand: Carlson · Form: POWDER [E0162]
Our assessment
The evidence shows that calcium is a critical mineral for your health, but the data does not support using a general L-glutamine powder as a primary source for it. You should not rely on this product for calcium intake. For bone and muscle health, targeted calcium supplements are more appropriate, and you should always discuss any new supplement with your healthcare provider.
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it is essential for neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the key that helps your muscles relax after contracting and keeps your bones strong.
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 [NIH ODS]. Very high blood levels of calcium 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
Data not available for the specific calcium content in this L-glutamine product. Do not use this product to meet your calcium needs. If you require a calcium supplement, choose a dedicated product and take it separately from medications listed above. Always consult your doctor before starting any new supplement regimen [NIH ODS].
