Natrol Kids Melatonin Berry

Our assessment

The evidence shows that calcium is a critical mineral for bone health, but the data does not support using Natrol Kids Melatonin Berry as a source of calcium. This product is labeled as a melatonin supplement, and data on its specific calcium content is not available. For calcium supplementation, you should look for a product specifically formulated to provide this mineral. The data confirms that calcium supports bone density and muscle relaxation [NIH ODS].

How it works

Calcium acts as a master regulator for your body's structure and function. It supports bone mineralization, helping to deposit minerals into your skeleton for strength, and it also plays a role in neuromuscular relaxation, which helps your muscles and nerves signal properly [NIH ODS].

Safety profile

FDA received 592,059 total adverse event reports across all supplements. For calcium specifically, some research suggests that high intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. 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]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

If your goal is to support bone health, do not rely on this melatonin product. Data not available for calcium content in Natrol Kids Melatonin Berry. Instead, choose a dedicated calcium supplement and take it with food for better absorption. Always discuss with your doctor before starting any new supplement, especially if you take prescription medications [NIH ODS].
