Qunol Extra Strength Turmeric 1000 mg

Our assessment

The evidence shows that Qunol Extra Strength Turmeric 1000 mg contains the mineral calcium as a key ingredient. Our assessment is that calcium is well-established for bone health, but you need to be aware of specific safety considerations and medication interactions when taking this supplement [NIH ODS].

How it works

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

Safety profile

Data not available for adverse events specific to this product. However, for the ingredient calcium, 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]. The FDA has received a total of 592,059 adverse event reports across all supplement categories [FDA data].

Our recommendation

You should be cautious with calcium supplementation. Calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these medications, take this supplement at least two hours apart from them. Start with a modest dose and monitor for side effects like constipation or nausea. We recommend discussing your total calcium intake from food and supplements with your healthcare provider [NIH ODS].
