NESS Nutritional Enzyme Support System Formula 9 Kidney Support

Our assessment

The evidence shows that this product contains calcium, a mineral that supports bone health and muscle function [NIH ODS]. However, the data on this specific formulation is limited, and you should be cautious about the risks associated with high calcium intake [NIH ODS]. Our assessment: this supplement may be helpful if you have a confirmed calcium deficiency, but it is not a substitute for kidney-specific medical treatment.

How it works

Think of calcium as a structural building block for your bones and a regulator of nerve signals. It supports bone mineralization and neuromuscular relaxation, meaning it helps your bones stay dense and your muscles relax properly after contracting [NIH ODS]. This mechanism can be beneficial for overall skeletal health, but it does not directly target kidney function.

Safety profile

Safety data for this specific product is limited. FDA has received a total of 592,059 adverse event reports across all supplements, but report counts for this specific product are not available [FDA data]. General risks from calcium include: high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium can include 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you do not take this supplement without first consulting your doctor. Because high calcium levels can worsen kidney function and interact with many medications, you should have your blood calcium levels checked before starting [NIH ODS]. If you have a diagnosed calcium deficiency, your healthcare provider can recommend a safe and targeted dose. For general kidney support, data not available for this product, so a balanced diet and prescribed treatments are safer options.
