MET-Rx Amino 3000
Brand: MET-Rx · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence for MET-Rx Amino 3000 is limited to the ingredients listed on the label. Data on the specific product formulation is not available. Our assessment must focus on the ingredient Calcium, which is one of the few components for which we have data. The data shows that Calcium supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that there is no specific efficacy data for this brand or its specific amino acid blend.
How it works
Calcium, when present, acts as a key structural component for your bones and a critical signaling molecule for your nerves and muscles. It supports bone density through mineral deposition and helps your muscles relax after contraction [NIH ODS]. For the amino acid blend itself, specific mechanism data is not available.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all dietary supplements. For Calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in your 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
Given the lack of specific data on the amino acid blend and the known risks of high calcium intake, our recommendation is cautious. If you are taking this product, be aware of the potential side effects from the calcium content. Data on the specific amino acid blend's effectiveness is not available. We recommend you consult with your healthcare provider before using this supplement, especially if you take any of the medications that interact with calcium [NIH ODS].
