NOW Sports Branched Chain Amino Acids
Brand: NOW Sports · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product contains Calcium, a mineral essential for bone health and nerve function. However, the data we have is specific to Calcium as an ingredient, not the full NOW Sports Branched Chain Amino Acids formula. Our assessment is that you should understand the risks and benefits of Calcium supplementation before using this product.
How it works
Think of Calcium as a structural building block for your bones and a signal regulator for your nerves. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements. For Calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels in the blood and urine 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]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Data not available for the specific product formula. For Calcium, do not exceed the recommended daily intake without medical supervision. Monitor for side effects like constipation or nausea. If you take any medications that interact with calcium (such as thyroid medication or antibiotics), take your calcium supplement at a separate time of day [NIH ODS]. Consult your doctor before starting any new supplement.
