Genestra Brands Amino L-Tyrosine
Brand: Genestra Brands · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Genestra Brands Amino L-Tyrosine, as listed, contains calcium. While calcium plays a vital role in your health, our assessment is that this product is primarily marketed for a different purpose, and you should be aware of the specific benefits and risks of its calcium content. Data on the amino L-tyrosine component itself is not available from the provided sources.
How it works
Think of calcium as a structural and signaling powerhouse. It supports bone density and mineral deposition, which is essential for a strong skeleton. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for all products, but specific report counts for this exact product are not available. Based on the ingredient data, 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. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
We recommend you do not take this supplement without first reviewing your total calcium intake from food and other supplements. Because calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin, you must consult your healthcare provider before starting this product [NIH ODS]. If you are looking specifically for L-tyrosine, data on that ingredient is not available in the provided materials.
