Metagenics Zinc A.G.
Brand: Metagenics · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Metagenics Zinc A.G. is a supplement containing calcium. Our assessment is that while calcium is essential for bone health, you need to be very careful with dosing. The data confirms that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. We advise you to check your total calcium intake from all sources before adding this supplement.
How it works
Think of calcium as a structural builder — it supports bone density and mineral deposition, which is crucial for keeping your skeleton strong. It also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS]. For these reasons, adequate calcium intake is foundational for overall health.
Safety profile
Safety data is available from 592,059 total adverse event reports across the supplement category [FDA data]. Specific risks include that high calcium 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]. Additionally, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation is to assess your dietary calcium intake first. If you are already getting enough from food, a supplement may not be necessary and could pose risks. If you do use it, take it separately from any medications listed above by at least two hours. Start with the lowest effective dose and do not exceed the daily recommended intake without professional guidance [NIH ODS].
