GNC Earth Genius Herb 360 Turmeric

Our assessment

The evidence shows that calcium is a foundational mineral for bone health, but the data from GNC Earth Genius Herb 360 Turmeric does not list calcium as an ingredient. Therefore, we cannot assess this specific product for calcium content. For general calcium supplementation, the data confirms it supports bone mineralization and neuromuscular relaxation [NIH ODS]. However, you should be aware that high intakes may pose risks, including an increased risk of heart disease and prostate cancer [NIH ODS].

How it works

Think of calcium as a structural builder for your bones and a signal regulator for your nerves. It works by supporting bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS].

Safety profile

Safety data for this specific GNC product is not available, as the ingredient list does not include calcium. For calcium supplements generally, 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]. The FDA received a total of 592,059 adverse event reports across all supplements, but this number is not specific to calcium or this product [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Since the GNC Earth Genius Herb 360 Turmeric product label does not list calcium as an ingredient, we cannot recommend it as a calcium source. If you are looking to supplement with calcium, consult your healthcare provider to determine your needs based on your diet and health status. Be mindful of potential interactions with your medications [NIH ODS].
