Brand: Member's Mark · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Member's Mark Iron Tablets, 65 mg, are a standard-dose iron supplement. Our assessment is based on the ingredient data available, which lists calcium as a key component of this product. You should be aware that the primary mineral here is iron, but the formulation also contains calcium, which can affect how your body absorbs the iron and interacts with other medications [NIH ODS].
How it works
Think of iron as a critical building block for your red blood cells, helping carry oxygen throughout your body. The calcium in this supplement supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should know that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. This means you need to carefully time when you take this supplement relative to other medicines.
Safety profile
FDA has received a total of 592,059 adverse event reports for all dietary supplements, though specific report counts for this product are not available. Regarding the calcium component, 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]. Some research also suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start by consulting your healthcare provider to determine if you need 65 mg of iron daily. Because this product contains calcium, take it at a different time than any medications listed in the interactions above — ideally separate by at least 2 hours. Data not available for specific side effect counts for this exact product. Choose a supplement that matches your individual mineral needs and medication schedule [NIH ODS].
