The evidence shows that this product contains calcium, but we do not have specific data on the other ingredients in Life Extension Branched Chain Amino Acids (Free Form).

For calcium, the data supports its role in bone health, but you should be aware of important safety considerations before taking this supplement [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though a specific count for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Side effects from high calcium levels include 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 several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available on the specific amino acid blend or dosing for this product, so we cannot recommend it based on the information provided. If you are considering it for the calcium content, discuss your total calcium intake from all sources with your healthcare provider to avoid exceeding safe levels and to check for medication interactions [NIH ODS].
