Nature's Way Calcium Mag & D Complex
Brand: Nature's Way · Form: CAPSULE [E0159]
Our assessment
The evidence shows that this product combines three well-studied nutrients for bone health. Our assessment is that the calcium, magnesium, and vitamin D3 in this formula work together to support bone density and muscle function. However, you need to be aware of the specific risks and interactions associated with calcium supplementation [NIH ODS].
How it works
Think of this supplement as a team of three key players. Calcium acts as the primary building block for your bones, supporting bone mineralization and density. It also helps your muscles relax and your nerves send signals properly. Magnesium works alongside calcium to support these functions, while vitamin D3 helps your body absorb the calcium you take in [NIH ODS].
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer. Side effects from too much calcium 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] [FDA data].
Our recommendation
We recommend you take this product only if you have a confirmed need for calcium supplementation. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take this supplement at least 2 hours apart from those medications. Data on the exact amounts of each ingredient in this specific product is not available, so check the label carefully [NIH ODS].
