Source Naturals Screen Time Stamina

Our assessment

Based on the available data, we cannot provide a complete assessment of Source Naturals Screen Time Stamina. The data provided does not include a list of ingredients or any specific health claims for this product. Our assessment must be limited to the ingredient calcium, which is listed in the data. The evidence shows that calcium is critical for bone health and nerve function, but its relevance to "screen time stamina" is not established [NIH ODS].

How it works

Calcium supports your body in two key ways: it promotes bone mineralization by helping deposit minerals into your bone structure, and it aids neuromuscular relaxation by supporting proper nerve signaling and muscle function [NIH ODS]. Without specific ingredient information for Source Naturals Screen Time Stamina, we cannot explain how this product would address screen time fatigue or eye strain.

Safety profile

Data not available for side effects specific to this product. However, for the ingredient calcium, FDA has received 592,059 total adverse event reports across all supplements. High calcium intakes may increase the risk of heart disease and prostate cancer. Excess calcium 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 data]. Calcium can also reduce absorption of medications such as bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].

Our recommendation

We cannot recommend Source Naturals Screen Time Stamina based on the data provided, as its ingredient list and intended benefits are not specified. If you are considering this product, you should consult the label directly for a full ingredient list. For general health, ensure you meet your calcium needs through diet, but be cautious with high-dose supplements due to the potential risks [NIH ODS].
