Our assessment
The evidence shows that NOW Sports Amino Complete contains calcium as a key mineral. For calcium, the data supports its role in bone health, but we must be clear about the risks. High intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Our assessment: you should only use this product if you need the amino acids, and you must account for the calcium content in your total daily intake.
How it works
Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition through a process called bone mineralization. It also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high levels 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]. Data on specific side effects for this product is not available.
Our recommendation
Start by checking if you already get enough calcium from your diet. If you take this supplement, take it at a different time than any prescription medications listed above to avoid absorption issues [NIH ODS]. Do not exceed the RDA for calcium from all sources combined. If you have a history of kidney stones, heart disease, or prostate cancer, consult your doctor before using this product [NIH ODS].
