Our assessment
The evidence shows that Genestra Brands Amino L-Tyrosine is a single-ingredient supplement. However, the data provided does not include any specific information on L-Tyrosine itself, such as dosage, mechanism of action, or clinical studies. Based on the available data, our assessment is limited to the ingredient Calcium, which is listed in the NIH ODS data. For L-Tyrosine specifically, data is not available.
How it works
For the ingredient Calcium, think of it as a structural and signaling agent. It supports bone mineralization and density, and it is essential for neuromuscular relaxation and nerve signaling [NIH ODS]. Data on how L-Tyrosine specifically works is not available.
Safety profile
The FDA received a total of 592,059 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. High levels 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Safety data for L-Tyrosine is not available.
Our recommendation
Because the provided data contains no specific information on L-Tyrosine’s benefits, risks, or proper dosing, we cannot make a confident recommendation for this product. For the Calcium component, you should be aware of the potential medication interactions and the risks associated with high intakes [NIH ODS]. For L-Tyrosine, consult a healthcare provider, as data is not available to guide safe and effective use.
