NOW Tri-Amino
Brand: NOW · Form: CAPSULE [E0159]
Our assessment
The evidence shows that the primary active ingredient in NOW Tri-Amino is calcium. Our assessment: calcium is essential for bone health, but it is one of the most common minerals that people already get enough of from food. Supplementing without knowing your baseline intake can introduce risks, including interactions with common medications and potential for adverse effects at high doses [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton and a cellular messenger for your nerves and muscles. It supports bone mineralization and density, and it helps your muscles relax and your nerves transmit signals properly [NIH ODS].
Safety profile
Data not available for specific side effects of NOW Tri-Amino. However, the FDA has received a total of 592,059 adverse event reports across all supplement categories, which underscores the importance of cautious use. For calcium specifically, high intakes can increase the risk of heart disease and prostate cancer. High levels in the blood and urine can cause poor muscle tone, poor kidney function, constipation, nausea, weight loss, extreme tiredness, frequent urination, 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].
Our recommendation
Our recommendation: do not take this supplement unless you have confirmed through a healthcare provider that you need additional calcium. Most adults meet their needs through diet alone. If you take any prescription medications, check for interactions before starting. Start with the lowest possible dose and monitor for side effects like constipation or nausea [NIH ODS].
