Ethical Nutrients Natural Formula Turmeric Flavonoid Complex

Our assessment

The evidence shows that calcium is a critical mineral for bone health, but the data also highlights important safety considerations you need to know. Our assessment is that this product provides calcium, which supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware of the potential risks associated with high intakes before starting supplementation.

How it works

Think of calcium as a structural and signaling powerhouse for your body. It supports bone density and mineral deposition, helping keep your skeleton strong. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

Data not available for this specific product's side effects. However, the FDA has received a total of 592,059 adverse event reports across all supplement categories, though this number does not specifically reflect this product [FDA data]. For calcium specifically, 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

Based on the data, you should be cautious with calcium supplementation. Do not exceed the recommended dietary allowance without medical supervision. Be aware of the potential interactions with prescription medications, and discuss your use of this supplement with your healthcare provider, especially if you have a history of kidney problems, heart disease, or are on any of the medications listed [NIH ODS].
