Source Naturals Screen Time Stamina
Brand: Source Naturals · Form: TABLET [E0155] On Market
Our assessment
The evidence shows that Source Naturals Screen Time Stamina contains Calcium, a mineral essential for bone health and nerve function. Our assessment: While calcium supports overall health, there is no specific data provided on how this product addresses "screen time stamina." The primary benefits are linked to calcium’s role in bone mineralization and neuromuscular relaxation [NIH ODS].
How it works
Think of calcium as a key structural component and a cellular messenger. It supports bone density by aiding in mineral deposition and helps your muscles relax and nerves signal properly after periods of screen use [NIH ODS]. This mechanism is general to calcium’s function, not unique to screen time.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplement categories. For calcium specifically, high intakes might increase the risk of heart disease and prostate cancer. High calcium levels can cause constipation, nausea, weight loss, extreme tiredness, frequent urination, and abnormal heart rhythms [NIH ODS]. Calcium can also reduce absorption of medications such as bisphosphonates, tetracycline antibiotics, and levothyroxine [NIH ODS].
Our recommendation
Data not available on the specific dosage or full ingredient list for this product. We recommend you check the label for exact amounts. If you take calcium, do not exceed the tolerable upper intake level and take it separately from thyroid or antibiotic medications by at least 2 hours [NIH ODS]. For screen time support, data on this product’s specific efficacy is not provided.
