MET-Rx Amino 3000
Brand: MET-Rx · Form: SUPPLEMENT FORM, OTHER [E0172]
Our assessment
The evidence shows that MET-Rx Amino 3000 contains calcium as an ingredient, but data on its specific amino acid profile is not available in the provided materials. For the calcium component, we can offer guidance. Calcium is a mineral essential for bone health and muscle function, but you should be aware of both its benefits and potential risks before taking this product.
How it works
Think of calcium as a structural builder and signaler in your body. It supports bone mineralization and density, and it also helps with neuromuscular relaxation and nerve signaling [NIH ODS]. This means it plays a dual role in keeping your skeleton strong and your muscles functioning properly.
Safety profile
The FDA has received a total of 592,059 adverse event reports across all supplement categories, but data on reports specific to this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high calcium 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
Start by checking if you already get enough calcium from your diet before adding this supplement. If you take this product, be mindful of the total calcium you consume from all sources to avoid exceeding safe levels. If you take any of the medications listed (such as thyroid medication or certain antibiotics), take this supplement at least two hours apart to avoid absorption issues [NIH ODS].
