Our assessment

The evidence shows that MacroLife Naturals Miracle Reds contains calcium, a mineral with clear benefits and important safety considerations. Our assessment: this product can contribute to your daily calcium intake, but you must be aware of the specific risks and interactions linked to this ingredient.

How it works

Calcium functions primarily in bone mineralization, supporting bone density and mineral deposition, and in neuromuscular relaxation, helping your muscles relax and nerves signal properly [NIH ODS]. Think of it as a key building block for your skeleton and a regulator for your muscle and nerve function.

Safety profile

The FDA received a total of 592,059 adverse event reports for all products in the database, but the specific number for this product is not available. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. Very 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]. Data not available for side effect report counts for this specific product.

Our recommendation

Start by checking your total daily calcium intake from food and all supplements to avoid exceeding recommended levels. Be aware that calcium can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. If you take any of these medications, separate your calcium dose by at least two hours. Data not available for a specific recommended dose from this product, so consult your healthcare provider before use.
