Nature's Way Alive! Calcium Bone Formula
Brand: Nature's Way · Form: TABLET [E0155]
Our assessment
The evidence shows that Nature's Way Alive! Calcium Bone Formula provides calcium, a mineral critical for bone health. Our assessment is that this supplement can be a useful tool for supporting your bone density, but you must be careful about your total daily intake from all sources, including food and other supplements.
How it works
Think of calcium as the primary building block for your skeleton. It supports bone mineralization by helping deposit minerals into your bone matrix, and it also plays a key role in neuromuscular relaxation by supporting muscle relaxation and nerve signaling [NIH ODS]. This means it helps your bones stay strong while also allowing your muscles to function properly.
Safety profile
Data not available for specific adverse events related to this product. However, based on the ingredient calcium, safety concerns exist. Some research suggests that high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. The FDA has received a total of 592,059 adverse event reports across all products, but this number is not specific to this formula [FDA data]. Importantly, calcium can reduce the absorption of several medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Start by reviewing your total daily calcium intake from food and other supplements to ensure you do not exceed safe levels. Take this supplement with a full glass of water and separate it from any medications listed in the interactions by at least 2 hours. Consult your doctor before use, especially if you have a history of kidney stones, heart disease, or take prescription medications [NIH ODS].
