Brand: NOW · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that melatonin is a popular supplement for sleep support, but the data for this specific product is incomplete. We cannot verify the dosage or ingredient purity from the label provided. For calcium, a separate ingredient in our data, the evidence confirms it is essential for bone health, but you must be cautious with dosing [NIH ODS].
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it helps your muscles relax and your nerves signal properly [NIH ODS].
Safety profile
Data not available for melatonin specifically. For calcium, high intakes may increase risk of heart disease and prostate cancer. Side effects of excessive calcium include constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. The FDA received 592,059 total adverse event reports across all supplements, but specific counts for this product are not available [FDA data].
Our recommendation
We cannot recommend this specific melatonin product due to missing data. For calcium, do not exceed the RDA without medical supervision. Always check for interactions with medications like bisphosphonates and antibiotics before starting calcium supplements [NIH ODS].
