The evidence shows that Sundown Naturals Calcium Magnesium And Zinc is a straightforward mineral supplement.

The data supports its role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of the calcium in this supplement as a structural building block for your bones and a key player in muscle and nerve signaling. It supports bone density and helps with muscle relaxation after contraction [NIH ODS]. This makes it useful for maintaining skeletal strength and supporting normal nerve function.
Safety profile
FDA received 592,059 total adverse event reports across all supplements, though specific numbers for this product are not available. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of certain medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend this supplement only if you have a confirmed need for additional calcium, magnesium, and zinc through diet or lab work. Be careful not to exceed your total daily calcium intake from food and supplements combined. If you take any of the listed medications, separate your doses by at least two hours [NIH ODS]. For most people, getting these minerals from food first is the safest and most effective approach [NIH ODS].
