Dr. Clark Research Association Dr. Clark Zentrum Multivitamin and Mineral Formula without Iron
Brand: Dr. Clark Research Association Dr. Clark Zentrum · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that this multivitamin and mineral formula is a standard, iron-free supplement. The data we have is limited to its calcium content, which provides a clear benefit for bone health, but also carries specific risks you need to be aware of [NIH ODS].
How it works
Calcium works as a building block for your bones, supporting bone density and mineralization. It also plays a role in neuromuscular relaxation, helping your muscles and nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer. Side effects from high blood levels include constipation, nausea, weight loss, extreme tiredness, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS] [FDA data].
Our recommendation
If you need a multivitamin without iron, this formula is a reasonable option. However, be mindful of your total calcium intake from all sources — including food and other supplements — to avoid the risks associated with high levels. Check with your doctor before starting, especially if you take medications like bisphosphonates or levothyroxine, as calcium can reduce their absorption [NIH ODS].
