Gaia Herbs Turmeric Supreme Heart

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health, but the data also raises significant safety concerns that you need to consider carefully. While calcium supports bone density and neuromuscular relaxation [NIH ODS], the high total number of adverse event reports associated with this ingredient — 592,059 — is a critical signal that cannot be ignored [FDA data].

How it works

Think of calcium as a structural builder for your skeleton and a signal regulator for your nerves and muscles. It works by supporting bone mineralization and mineral deposition, and it helps your muscles relax and your nerves signal properly after contraction [NIH ODS].

Safety profile

FDA received 592,059 adverse event reports related to this ingredient. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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

Data not available for a specific dose or formulation for this product. Given the 592,059 adverse event reports and the potential for serious side effects including heart rhythm abnormalities, proceed with extreme caution. Speak with your doctor before taking this supplement, especially if you take any medications or have a history of kidney or heart conditions [FDA data] [NIH ODS].
