Allergy Research Group Solution of Magnesium

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health and nerve function. However, the data on calcium supplementation is nuanced. While calcium supports bone mineralization and neuromuscular relaxation, high intakes may carry risks [NIH ODS]. We recommend a careful approach based on your individual dietary intake.

How it works

Think of calcium as a key structural component for your skeleton. It works by supporting bone density and mineral deposition, helping keep your bones strong. It also plays a role in neuromuscular relaxation, which supports proper muscle relaxation and nerve signaling throughout your body [NIH ODS].

Safety profile

Data not available for this specific product's side effects. However, for calcium supplements broadly, high levels 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]. Some research suggests high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. The FDA has received 592,059 total adverse event reports across all supplement categories [FDA data].

Our recommendation

We advise you to be cautious with this product. Before supplementing, assess your total calcium intake from food and other supplements. Avoid exceeding the tolerable upper intake level unless directed by your doctor. Be aware that calcium can reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your healthcare provider to see if this supplement is appropriate for you.
