Good 'N Natural Coral Calcium Plus Vitamin D3 & Magnesium
Brand: Good 'N Natural · Form: CAPSULE [E0159]
Our assessment
The evidence shows that Good 'N Natural Coral Calcium Plus Vitamin D3 & Magnesium is a combination supplement, but the available data only supports claims for its primary ingredient, calcium. Our assessment is that while calcium is essential for bone health, you should be cautious with this product because the specific benefits of "coral calcium" are not proven superior to standard calcium supplements. Data not available for the specific brand or the Vitamin D3 and magnesium content in this product.
How it works
Think of calcium as a structural building block for your skeleton. It works by supporting bone mineralization and density, and it also plays a role in neuromuscular relaxation and nerve signaling [NIH ODS]. The product's name suggests it includes Vitamin D3 and magnesium, which can aid calcium absorption, but no specific data on these additional ingredients was provided for this analysis.
Safety profile
FDA received 592,059 total adverse event reports for all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Side effects from high calcium levels include poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent urination, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. You should be aware that calcium can reduce the absorption of bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
We recommend you get your calcium from food first. If you need a supplement, choose a standard calcium carbonate or citrate product rather than "coral calcium," as the data does not support added benefits. Be sure to take calcium supplements separately from the medications listed in the safety profile. Start with a low dose and do not exceed the RDA without a doctor's guidance [NIH ODS].
