DemetRx Pharmaceuticals Pre-Tabs DHA Omega-3 DHA Capsule

Our assessment

The evidence shows that this product, DemetRx Pharmaceuticals Pre-Tabs DHA Omega-3 DHA Capsule, contains calcium as its listed ingredient. Our assessment is that calcium is a well-researched mineral, but you need to be aware of its specific benefits and risks. The data supports its role in bone health, but high intakes may carry significant health risks [NIH ODS].

How it works

Think of calcium as a structural builder for your bones. It supports bone mineralization and density, which is essential for maintaining a strong skeleton as you age. Calcium also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

Data not available for this specific product's adverse events; the total FDA database contains 592,059 reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. 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]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you consult with your healthcare provider before starting this supplement. Given the potential risks associated with high calcium intakes, including heart disease and medication interactions, you need to have your calcium levels checked and discuss your overall diet. Do not exceed the recommended dose on the label, and be aware that taking calcium with other medications may require timing adjustments [NIH ODS].
