Our assessment

For this specific product, data on L-Tyrosine itself is not available in the provided data.

How it works
Calcium acts as a master regulator for your body's structure and function. It supports bone mineralization and density, and plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as the essential mineral that helps your muscles relax after contracting and keeps your bones strong and dense.
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. Very 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] [FDA data]. Calcium can also reduce the absorption of several medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Before taking this product, check if you already get enough calcium from your diet. Do not exceed the RDA unless directed by your doctor. If you take any of the listed medications, separate calcium intake by at least 2 hours. Because specific data on L-Tyrosine is not available in the provided information, we cannot comment on its effects. Speak with your healthcare provider to determine if this supplement is appropriate for your individual needs [NIH ODS].
