Nutrition Rescue Buffered Vitamin C

Our assessment

The evidence shows that this product contains the mineral calcium, which is essential for bone health. However, the data available is limited to the calcium ingredient alone, and no specific information about the "Nutrition Rescue Buffered Vitamin C" product formulation is provided beyond that. Our assessment is that the calcium content can support your bone density, but you should be aware of the potential risks associated with high intake [NIH ODS].

How it works

Think of calcium as a structural building block for your skeleton. It supports bone mineralization and is crucial for neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your bones stay dense and your muscles relax properly after contraction.

Safety profile

Data not available for this specific product's adverse events. The FDA has received a total of 592059 adverse event reports across all supplement categories, but this number is not specific to this product [FDA data]. Regarding calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. 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 [NIH ODS].

Our recommendation

You should check the label for the exact amount of calcium per serving. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Because the data for this specific product is incomplete, we recommend consulting your healthcare provider before starting this supplement to ensure it is safe and appropriate for your individual health needs.
