Higher Nature Glutamine Amino Acid 500 mg
Brand: Higher Nature · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains 500 mg of glutamine, an amino acid. However, the available data on glutamine specifically is limited. Our assessment must focus on the ingredient calcium, which is listed in the NIH ODS data. For calcium, the evidence shows it supports bone mineralization and neuromuscular relaxation [NIH ODS]. For glutamine specifically, data on its benefits is not available from the provided sources.
How it works
Think of calcium as a structural builder — it supports bone density through mineral deposition and helps your muscles relax and nerves signal properly [NIH ODS]. For glutamine, a detailed mechanism of action is not available from the provided data.
Safety profile
For the ingredient calcium, high intakes might increase the risk of heart disease and prostate cancer. 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]. The FDA has received a total of 592,059 adverse event reports across all products, but a specific report count for this product is not available [FDA data].
Our recommendation
You should be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. For glutamine specifically, data is not available to form a targeted recommendation. Consult your healthcare provider before starting this supplement, especially if you take any of the listed medications.
