The evidence shows that Metagenics Zinc A.G. is a product that contains calcium, and based on the data provided, we cannot make a specific assessment about its effectiveness for any particular health goal. The data provided does not include specific information about zinc or the complete formulation of this product. For the ingredient calcium, which is listed, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, without specific data on the product's intended use, we cannot recommend it for any specific condition.

How it works

Based on the data, the calcium in this product acts as a structural builder for your bones and a signal regulator for your muscles. It supports bone density by aiding in mineral deposition and helps your muscles relax by supporting nerve signaling [NIH ODS].

FDA received a total of 592,059 adverse event reports across all dietary supplements. For the ingredient calcium specifically, safety data indicates that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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

Our assessment is that you should consult with your healthcare provider before starting this supplement, especially to discuss your current calcium intake from food and other supplements. The data shows that calcium supplements have significant potential interactions with common medications and risks at high levels [NIH ODS]. Because we lack specific data on the zinc content and the intended use of this product, a more targeted recommendation cannot be made.
