Onnit Mineral Electrolytes Fresh Lime Flavor

Our assessment

The evidence shows that Onnit Mineral Electrolytes Fresh Lime Flavor provides calcium, a mineral essential for bone health and nerve function. However, based on the data, the product's exact calcium content per serving is not listed, and the total FDA adverse event count for all products in this category is 592,059 reports. Our assessment is that while calcium is a well-established nutrient, the lack of precise dosing information on the label limits our ability to make a specific recommendation for this product.

How it works

Think of calcium as a structural builder and a signal conductor. It supports bone mineralization, which helps maintain bone density, and it aids in neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly [NIH ODS].

Safety profile

Data not available on side effects specific to this product. However, for calcium in general, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels can cause poor muscle tone, poor kidney function, low phosphate levels, 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 absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Because the label does not provide the specific calcium amount per serving, we cannot recommend this product for targeted calcium supplementation. If you are considering this for general hydration, be aware that the FDA data includes 592,059 total adverse event reports across similar product categories. For reliable calcium intake, choose a product with a clearly stated dose and consult your healthcare provider about your individual needs [NIH ODS].
