Nature's Plus Life Blast Xtreme Energy Natural Berry Blast Flavor

Our assessment

The evidence shows that this product contains calcium, a mineral essential for bone health, but the specific benefits and risks depend heavily on your current diet and health status. We cannot assess the "xtreme energy" claim from the data provided, as the only listed ingredient with available information is calcium. For most adults, meeting calcium needs through food is preferred, and supplementation should be approached with clear medical guidance [NIH ODS].

How it works

Think of calcium as a key structural component for your skeleton. It works through bone mineralization to support bone density and mineral deposition. It also plays a critical role in neuromuscular relaxation, helping your muscles relax and nerves signal properly after contraction [NIH ODS].

Safety profile

The FDA has received 592,059 total adverse event reports across all supplements. For calcium specifically, data indicates that high intakes might increase the risk of heart disease and prostate cancer. Very 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] [FDA data]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We recommend you do not use this product to address fatigue without first consulting your doctor. The data does not support calcium as a treatment for low energy. If you are considering this for its calcium content, aim to get your calcium from dietary sources first. If you take calcium supplements, be aware of the potential interactions with medications listed above and discuss your total calcium intake (from food and supplements) with your healthcare provider to avoid exceeding safe levels [NIH ODS].
