GNC Earth Genius Energizing TonIQ Raspberry Green Tea

Our assessment

The evidence shows that this product is a green tea supplement, and the data provided does not contain specific research or safety information for green tea or the GNC Earth Genius Energizing TonIQ Raspberry Green Tea formula. Our assessment is based solely on the ingredient data available: Calcium. Calcium is a mineral essential for bone health and nerve function, but it has significant safety considerations at high intakes [NIH ODS].

How it works

Think of calcium as a structural and signaling mineral. It supports bone density and mineral deposition, and it helps your muscles relax and your nerves send signals properly [NIH ODS]. For this specific product, we do not have data on the amount of calcium it contains or how it works with the other ingredients.

Safety profile

Data is limited for this specific product. The FDA has received 592,059 total adverse event reports across all supplements, but report counts for this specific product are not available. For the ingredient calcium, high intakes may increase the risk of heart disease and prostate cancer. High blood and urine levels 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 absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

Without specific dosage and ingredient data for this product, we cannot make a confident recommendation. If you choose to use it, be aware of the risks associated with high calcium intake and check the label for the exact amount of calcium per serving. If you take any medications, especially antibiotics or thyroid medication, consult your doctor before use due to potential absorption issues [NIH ODS]. For a full evaluation, data on the green tea content and other ingredients is required.
