Our assessment
The evidence shows that Sundown Naturalist Calcium 600 + D provides a meaningful level of calcium per serving, which is essential for bone health. However, you need to be aware of the safety considerations and potential medication interactions that come with calcium supplementation. The data supports its use for maintaining bone density, but only if you manage your total daily calcium intake carefully [NIH ODS].
How it works
Think of calcium as the structural building block for your bones. It supports bone mineralization and density, and it also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for this product category. High calcium intakes might increase the risk of heart disease and prostate cancer. Side effects from high levels in the blood and urine 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 [FDA data] [NIH ODS].
Our recommendation
Start by calculating your total daily calcium intake from food and supplements. Do not exceed the tolerable upper intake level. Be aware that calcium can reduce the absorption of several medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin. Take this supplement at a separate time from these medications [NIH ODS].
