Progressive Laboratories Amino Blend

Our assessment

The evidence shows that Progressive Laboratories Amino Blend contains calcium as a key ingredient. Our assessment: Calcium is a well-studied mineral that supports bone health and nerve function, but the data also indicates important safety considerations you need to be aware of before taking this supplement [NIH ODS].

How it works

Think of calcium as a structural builder and a signal messenger. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. At the same time, calcium supports muscle relaxation and proper nerve signaling throughout your body [NIH ODS].

Safety profile

FDA received a total of 592,059 adverse event reports across all supplements, though specific data for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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] [FDA data]. Calcium can also reduce the absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Start by checking your current calcium intake from food and other supplements. Be cautious about exceeding the recommended daily intake, and take this supplement at a different time than any prescription medications you may be using. Consult your doctor before starting, especially if you have kidney issues or take thyroid or antibiotic medications [NIH ODS].
