Pinnacle Labs Tea Rexx Extreme

Our assessment

The evidence shows that Pinnacle Labs Tea Rexx Extreme contains calcium as a primary ingredient. Based on the data provided, we cannot make a specific assessment of this product's effectiveness for weight loss or energy, as no studies on this specific formulation are listed. However, we can assess the ingredient calcium itself. For general health, calcium is essential for bone mineralization and neuromuscular relaxation [NIH ODS].

How it works

Think of calcium as a structural builder for your skeleton. It supports bone density and mineral deposition, and it also plays a role in helping your muscles relax and your nerves signal properly [NIH ODS]. Without adequate calcium, your body will leach it from your bones, which can weaken them over time.

Safety profile

The FDA has received a total of 592,059 adverse event reports across all supplements, but specific report counts for this product are not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Signs of excessive calcium in the blood and urine include 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 medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you check the product label for the exact amount of calcium per serving. The data provided does not include a recommended daily allowance or specific dosage for this product. If you are taking any medications, especially antibiotics or thyroid medication, take this supplement at least two hours apart from those drugs [NIH ODS]. Because high calcium intake carries risks, we advise you to consult your doctor before starting this product, particularly if you have kidney concerns or a history of heart disease. Data on the other ingredients in this blend is not available.
