Swanson Premium Brand Calcium Citrate Complex
Brand: Swanson Premium Brand · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is a critical mineral for bone health, but you need to be careful with dosing. The data indicates that calcium supports bone mineralization and neuromuscular function [NIH ODS]. However, high intakes carry real risks, so you should not take more than the recommended amount without medical guidance.
How it works
Think of calcium as a structural builder for your bones and a signal conductor for your nerves. It works through bone mineralization, supporting bone density and mineral deposition, and it also supports muscle relaxation and nerve signaling [NIH ODS]. This makes it essential for your entire musculoskeletal system.
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Also, calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by reviewing your total calcium intake from both food and supplements. Do not exceed the RDA without a doctor's supervision, and be aware that high intakes carry significant risks [NIH ODS]. If you take any of the listed medications, separate your calcium dose by at least two hours to avoid absorption issues [NIH ODS].
