Natural Factors Super Multi Iron Free Multi Vitamin & Mineral Complex for Everyone
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that the calcium in this supplement is a well-researched mineral for bone health. However, you should be aware of the potential risks associated with high intakes, including a possible increased risk of heart disease and prostate cancer [NIH ODS]. For most adults, getting calcium from food sources is preferred.
How it works
Think of calcium as a structural building block for your skeleton. It supports bone mineralization and density, and it also plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. This means it helps your muscles relax and your nerves send messages properly.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplement categories. 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 urination, 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
Because this is an iron-free formula, it may be a good option if you do not need extra iron. However, data on the specific dosage in this product is not available. You should aim to meet your calcium needs through diet first, and consult your doctor before adding this supplement, especially if you take any of the medications listed in the safety profile [NIH ODS].
