Nature's Way Calcium Complex Bone Formula
Brand: Nature's Way · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Nature's Way Calcium Complex Bone Formula provides calcium, a mineral essential for bone health. Our assessment is that this product can be a useful tool for meeting your calcium needs, but you must be aware of its safety profile and potential interactions with medications [NIH ODS].
How it works
Think of calcium as a structural building block for your bones. It supports bone density and mineral deposition, which is critical for maintaining strong bones as you age. Additionally, calcium plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
Data is available from the FDA, which received 592,059 total adverse event reports for calcium-containing supplements [FDA data]. High calcium intakes may increase the risk of heart disease and prostate cancer. Side effects from high blood and urine calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, and abnormal heart rhythms [NIH ODS].
Our recommendation
Start with the serving size on the label and do not exceed it unless directed by your doctor. Take calcium supplements with food to improve absorption. If you take bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, or phenytoin, take this supplement at least two hours apart from those medications to avoid reduced absorption [NIH ODS].
