Our assessment
The evidence shows that MET-Rx Amino 3000 is a protein supplement, and its primary active ingredient, calcium, supports bone health. However, you should be aware of the specific benefits and risks associated with calcium intake from any source, including this product. Data not available on the specific amount of calcium in this product or its other ingredients.
How it works
Think of calcium as a builder and messenger. It supports bone density and mineral deposition through bone mineralization, and it also helps your muscles relax and nerves signal properly [NIH ODS]. This makes it essential for maintaining strong bones and a healthy nervous system.
Safety profile
FDA received 592,059 total adverse event reports across all dietary supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels of calcium 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 the product label for the exact calcium content per serving. If you take this supplement, be mindful of your total daily calcium intake from all sources — including food and other supplements — to avoid exceeding safe levels. Separating calcium supplements from certain medications by at least two hours may help with absorption [NIH ODS]. Consult your healthcare provider to determine if this product is appropriate for you, especially if you take any of the medications listed above.
