Nature's Way Calcium Citrate
Brand: Nature's Way · Form: CAPSULE [E0159] On Market
Our assessment
The evidence shows that calcium is essential for bone health, but the form in Nature's Way Calcium Citrate offers specific advantages. Our assessment: this supplement is a solid choice for individuals who need calcium but have trouble with absorption or stomach sensitivity, as calcium citrate is more easily absorbed than other forms [NIH ODS].
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 role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS]. Because it is in the citrate form, you can take it with or without food, making it more convenient for daily use [NIH ODS].
Safety profile
The FDA has received 592,059 total adverse event reports for all supplements, though specific numbers for this product are not available. For calcium generally, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive intake include constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend starting with a dose that meets your individual needs, typically 500–600 mg per day from supplements, and taking it at least two hours apart from any medications listed above [NIH ODS]. Choose calcium citrate for better absorption, especially if you take acid-reducing medications or have a sensitive stomach [NIH ODS]. Do not exceed the tolerable upper intake level without medical supervision [NIH ODS].
