Brand: Rainbow Light · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Rainbow Light Magnesium Calcium+ provides calcium, a mineral essential for bone health. Our assessment is that this product can help you meet your calcium needs, but you must be careful with total intake from all sources to avoid the risks associated with high calcium levels [NIH ODS].
How it works
Think of calcium as a building block for your bones. It supports bone density and mineral deposition, which keeps your skeleton strong. It also plays a role in neuromuscular relaxation, meaning it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
FDA received a total of 592,059 adverse event reports for all dietary supplements. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High levels of calcium in the blood and urine can cause 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 supplement only if you have a known calcium deficiency or cannot get enough from your diet. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Consult your doctor before starting, especially if you take any of these medications.
