Source Naturals Super Amino Night
Brand: Source Naturals · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that the calcium in this product is primarily a structural mineral for your bones. Based on the data, we cannot give a blanket recommendation for a "nighttime" amino acid formula because the specific studies provided do not address the combination of ingredients in this product. The available data focuses on calcium, not the full formula.
How it works
Calcium acts as a master regulator for bone density through bone mineralization and supports neuromuscular relaxation [NIH ODS]. This means it helps your muscles relax and supports proper nerve signaling, which is why it is sometimes included in nighttime formulas. However, the data does not confirm that this specific product's blend of amino acids works synergistically for sleep.
Safety profile
FDA received a total of 592,059 adverse event reports across all supplements, but specific report counts for this exact product are not available. For calcium specifically, high intakes can cause constipation, nausea, poor kidney function, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce the absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Do not take this product without first reviewing the label for the exact calcium dose. If you are taking any prescription medications, separate this supplement by at least 2 hours to avoid absorption issues [NIH ODS]. For most adults, getting calcium from food is preferable. Data not available on the specific amino acid blend's safety or effectiveness for sleep support.
