Blue Sky Blue Energy Wild Berry Flavor

Our assessment

The evidence shows that this product, Blue Sky Blue Energy Wild Berry Flavor, contains calcium as its listed ingredient. Our assessment is that while calcium is essential for health, you should be aware of its specific benefits and risks before taking this supplement. The data we have is limited to the calcium content, so we cannot evaluate other ingredients that may be present [NIH ODS].

How it works

Think of calcium as a key building block for your body. It works primarily through bone mineralization, helping to support your bone density and mineral deposition. Calcium also plays a critical role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS].

Safety profile

FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in your 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] [FDA data].

Our recommendation

Our recommendation is to use this product with caution. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these medications, you should separate your calcium intake by at least two hours. Data on the exact dosage per serving is not available from the provided information, so consult the product label carefully. Start with a low amount and monitor how you feel [NIH ODS].
