Nutrex Research UltraFit Series Amino Charger +Hydration Grape Apple

Our assessment

The evidence shows that Amino Charger +Hydration is formulated with calcium, a mineral essential for bone health and muscle function. However, we cannot assess the complete effectiveness of this specific product because data on its other active ingredients is not available. For the calcium component, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton. It helps deposit minerals into bone tissue to maintain density and strength. At the same time, it acts as a nerve signal regulator, supporting muscle relaxation and proper nerve signaling throughout your body [NIH ODS].

Safety profile

The FDA has received 592,059 total adverse event reports across all supplement categories. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High levels of calcium in your 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].

Our recommendation

If you choose to use this product, be aware that calcium can interfere with the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Because data on the full ingredient profile of this specific supplement is not available, we recommend consulting your healthcare provider before starting it to ensure it fits your individual health needs and does not conflict with any medications you take.
