Allergy Research Group Calcium Citrate
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is essential for bone health, but you need to be careful with dosing. Our assessment is that calcium citrate is a well-absorbed form, but you should not exceed the recommended daily intake without medical guidance [NIH ODS].
How it works
Think of calcium as a structural builder for your bones. It supports bone density and mineral deposition, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all calcium supplements. High calcium 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].
Our recommendation
Start with a moderate dose and take it with food for best absorption. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Space your calcium supplement by at least two hours from these medications. Data not available on specific interactions for this brand.
