GNC Preventive Nutrition Multi-Enzyme Formula
Brand: GNC Preventive Nutrition · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that GNC Preventive Nutrition Multi-Enzyme Formula contains calcium, a mineral essential for bone health. However, the data provided does not include specific enzyme amounts or a complete ingredient list for this product. You should know that the benefits and risks of this supplement are tied directly to its calcium content, as that is the only ingredient with available data [NIH ODS].
How it works
Think of calcium as a structural building block for your bones and a signaling molecule for your nerves and muscles. It supports bone mineralization and density, and it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
The FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are data not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels of calcium 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 the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Because the complete ingredient list and enzyme amounts are data not available, you should treat this product cautiously. If you choose to take it, be aware of the calcium content and its potential interactions with medications. For a more informed decision, look for a supplement with a fully disclosed label and consult your healthcare provider [NIH ODS].
