Shiff Melatonin Ultra 3 mg
Brand: Shiff · Form: TABLET [E0155] On Market
Our assessment
Our assessment: The product Shiff Melatonin Ultra 3 mg contains melatonin, but the data provided here is for calcium. Based on the available data, we cannot assess melatonin directly. For calcium, the evidence shows it supports bone mineralization and neuromuscular relaxation [NIH ODS]. Data for the specific melatonin product you asked about is not available.
How it works
Think of this product's ingredient, calcium, as a structural builder and signaler — it helps deposit minerals into your bone matrix for density and supports proper muscle relaxation and nerve signaling throughout your body [NIH ODS].
Safety profile
FDA received 592,059 adverse event reports across all supplements. For calcium specifically, high intakes may increase the risk of heart disease and prostate cancer [NIH ODS]. High blood and urine levels of calcium 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 reduce absorption of medications including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Because the data provided is for calcium, not melatonin, you should consult a healthcare provider before using Shiff Melatonin Ultra 3 mg. For calcium, do not exceed the recommended dietary allowance without medical supervision, and take calcium supplements separately from your other medications by at least two hours [NIH ODS].
