PhysioLogics Iron Plex
Brand: PhysioLogics · Form: CAPSULE [E0159]
Our assessment
The evidence shows that while the product label for PhysioLogics Iron Plex is not fully detailed in the data, the primary ingredient of concern based on available data is calcium. Calcium is a mineral essential for bone health and nerve function, but you need to be aware of its specific risks and interactions before taking this supplement [NIH ODS].
How it works
Think of calcium as a structural and signaling agent in your body. It supports bone mineralization, helping deposit minerals into your skeleton to maintain density, and it assists in neuromuscular relaxation, which is critical for proper muscle function and nerve signaling [NIH ODS].
Safety profile
The FDA has received a total of 592,059 adverse event reports for this product category. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels 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] [FDA data].
Our recommendation
Before starting PhysioLogics Iron Plex, you should check with your healthcare provider about your calcium and iron levels. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. If you take any of these, separate your supplement by at least 2 hours [NIH ODS]. Data on the specific iron content and dosage for this product is not available, so rely on professional guidance for your individual needs.
