Brand: Nature Made · Form: SOFTGEL CAPSULE [E0161]
Our assessment
The evidence shows that the combination of melatonin and L-theanine in this product targets sleep support, but the data provided here focuses on calcium, not these specific ingredients. For calcium, our assessment is that it is a well-studied mineral for bone health, but you need to be cautious about intake levels to avoid risks [NIH ODS].
How it works
Calcium acts as a master regulator for your body. It supports bone mineralization and density, and it plays a key role in neuromuscular relaxation and nerve signaling [NIH ODS]. Think of it as a critical building block for your skeleton and a calming signal for your muscles and nerves.
Safety profile
Data not available for melatonin and L-theanine specifically. For calcium, the safety profile includes important risks. High calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. High levels 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]. FDA has received 592059 total adverse event reports across all supplements, though specific counts for this product are not available [FDA data].
Our recommendation
Data not available to recommend a specific dose for this product. If you are taking calcium, be aware it can reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. Start with a low dose and consult your healthcare provider to ensure this product is safe for you, especially if you take any of these medications [NIH ODS].
