Douglas Laboratories Timed Release Iron

Our assessment
The evidence shows that calcium is a critical mineral for bone health, but the data does not support taking it without careful consideration of your individual needs and risks. For the product "Douglas Laboratories Timed Release Iron," the label lists iron as the ingredient, not calcium, so our analysis focuses on calcium as a general supplement ingredient. You should not assume this product provides calcium benefits.
How it works
Calcium acts as a master builder for your bones, supporting bone density and mineral deposition [NIH ODS]. It also plays a role in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. Think of it as the structural framework your body relies on daily.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, but specific report counts for calcium alone are not available. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high levels in the blood and urine include 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 absorption of medications like bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
You should not take calcium supplements unless you have a confirmed deficiency or a specific medical need. Data not available on the exact calcium content of this product, so you cannot rely on it for calcium support. If you need calcium, get it from food first and talk to your doctor about your total intake from all sources [NIH ODS]. Always check with a healthcare provider before adding any supplement, especially if you take prescription medications.
