NESS Nutritional Enzyme Support System Formula 20 Digest

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function [NIH ODS]. However, our assessment is that you should approach this supplement with caution. Calcium is best obtained through diet, and high-dose supplementation carries real risks. We do not have sufficient data to recommend this specific product for general use.

How it works

Calcium acts as a master regulator in your body. It supports bone mineralization, helping maintain strong bone density, and is critical for neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly [NIH ODS]. Think of it as the structural foundation for your skeleton and a key player in your nervous system.

Safety profile

FDA has received 592,059 total adverse event reports for products in this category [FDA data]. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Toxicity signs include 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 the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Data not available for the specific dosage or efficacy of this blend. Our recommendation is to prioritize calcium from food sources like dairy, leafy greens, and fortified foods. If you need a supplement, choose a single-ingredient calcium product with a known dose (typically 500–600 mg per serving) and take it separately from other medications. Discuss any supplement with your healthcare provider first [NIH ODS].
