NutriCology Melatonin 3 mg

Our assessment

The evidence shows: Melatonin is a popular supplement for sleep support, but for this specific product, NutriCology Melatonin 3 mg, we have very limited data to assess its effects. The label information is not available, and the ingredient data provided only covers calcium, not melatonin. This means we cannot make a specific recommendation for this product based on the data you have supplied.

How it works

While we lack specific data on melatonin, the ingredient listed in the available data is calcium. Calcium supports bone mineralization and density, and it aids neuromuscular relaxation and nerve signaling [NIH ODS]. You can think of calcium as a key structural component for your bones and a signal regulator for your muscles and nerves [NIH ODS].

Safety profile

Data not available for melatonin specifically. For calcium, the data shows that high calcium 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]. The FDA has received 592,059 total adverse event reports for all supplements, but a specific count for this product is not available [FDA data].

Our recommendation

Because the label information for this specific product is not available and the only ingredient data provided is for calcium, we cannot recommend this product for melatonin supplementation. If you are seeking a melatonin supplement, look for a product with a clear label and third-party testing. For calcium needs, be cautious with high doses and discuss any supplementation with your healthcare provider to avoid interactions with medications like bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
