Our assessment
The evidence shows that Genestra Brands Amino L-Tyrosine is a dietary supplement, but our assessment is based on the only ingredient data provided, which is for calcium. For the specific effects of L-Tyrosine itself, data is not available in the provided information. Based on the calcium data, this product may support bone health, but you should be aware of potential risks and interactions [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signaling molecule for your nerves and muscles. It supports bone density through mineralization and helps your muscles relax and nerves communicate properly [NIH ODS].
Safety profile
The FDA received 592,059 total adverse event reports across all 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].
Our recommendation
Our recommendation is to be cautious. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Before taking this product, consult with your healthcare provider to determine if calcium supplementation is appropriate for you and to check for any potential medication interactions [NIH ODS].
