Allergy Research Group Calcium Citrate
Brand: Allergy Research Group · Form: CAPSULE [E0159]
Our assessment
The evidence shows that calcium is an essential mineral for your bone health and nerve function. Our assessment is that calcium citrate, the form in this product, is often better absorbed than other forms, especially if you take it on an empty stomach. However, we must be careful with dosing, as the data reveals significant risks at high intake levels [NIH ODS].
How it works
Think of calcium as a builder and signaler in your body. It supports bone mineralization, helping to deposit minerals and maintain bone density. It also plays a key role in neuromuscular relaxation, allowing your muscles to relax and your nerves to signal properly after they fire [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports for products containing this ingredient [FDA data]. The data warns that high calcium intakes might increase the risk of heart disease and prostate cancer. High levels in your 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
Our recommendation is to take calcium supplements only to meet your daily needs and not to exceed them. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take them at separate times [NIH ODS]. Start with a low dose and monitor for side effects like constipation or nausea. Data not available for specific dosing guidance for this product.
