NutriCology Calcium Citrate
Brand: NutriCology · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: Calcium is a critical mineral for bone health and nerve function, but the data shows you need to be precise with dosing. The NIH ODS confirms calcium supports bone density and neuromuscular relaxation [NIH ODS]. However, high intakes carry real risks, so this supplement is best used under professional guidance.
How it works
Think of calcium as a structural builder and a signal messenger. It deposits into your bones to keep them dense and strong, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. The citrate form in this product may be better absorbed if you have low stomach acid or take acid-reducing medications.
Safety profile
FDA received 592,059 total adverse event reports across all calcium products. Data not available for this specific brand. Side effects from high calcium intake include constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [FDA data] [NIH ODS]. High levels in blood and urine can also cause poor muscle tone, poor kidney function, and a high risk of death from heart disease [NIH ODS]. Some research suggests high intakes may increase the risk of heart disease and prostate cancer [NIH ODS].
Our recommendation
Start with the lowest effective dose, typically 500 mg or less per day from supplements, and get your total intake (diet plus supplements) checked by a healthcare provider. Calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin — take this supplement at least 2 hours apart from these medications [NIH ODS]. Do not exceed the tolerable upper intake level without medical supervision.
