Source Naturals Coral Calcium Multi-Mineral Complex
Brand: Source Naturals · Form: TABLET [E0155]
Our assessment
The evidence shows that calcium is a well-established mineral for bone health, but the specific combination in this product is not backed by unique clinical trials. Our assessment: Calcium from the Coral Calcium Multi-Mineral Complex can support your bone density and nerve function, but you should be aware of potential risks from high intake [NIH ODS].
How it works
Think of calcium as a structural builder for your skeleton. It supports bone mineralization, which is the process of depositing minerals to keep your bones dense and strong. It also plays a key role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after contraction [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, side effects can include constipation, nausea, and weight loss at very high intakes. More serious risks include abnormal heart rhythms and a high risk of death from heart disease. High calcium levels in the blood can also cause poor kidney function and extreme tiredness [FDA data] [NIH ODS].
Our recommendation
Start by checking your total calcium intake from food and other supplements. If you take this product, be aware that calcium can reduce the absorption of medications like bisphosphonates, tetracycline antibiotics, and levothyroxine — space them by at least 2 hours. Data on the specific benefits of coral calcium over standard calcium sources is not available [NIH ODS].
