PhysioLogics Iron Plex
Brand: PhysioLogics · Form: CAPSULE [E0159]
Our assessment
The evidence shows that while calcium is essential for bone health, you should approach supplementation with caution. High calcium intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. For this specific product, PhysioLogics Iron Plex, the primary ingredient listed is calcium, not iron as the name might suggest. Data on the exact formulation is not available.
How it works
Calcium acts as a master regulator in your body. It supports bone density and mineral deposition through a process called bone mineralization. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all dietary supplements. For calcium specifically, 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you get your calcium levels checked before starting any supplement. If you need calcium, focus on food sources first. If you take a supplement, take it separately from other medications to avoid absorption issues [NIH ODS]. Do not exceed the recommended intake without consulting your doctor, as high intakes carry significant risks [NIH ODS].
