Oral supplements typically take 4-8 weeks of consistent use to show noticeable effects, with optimal results around 3-4 months
For everyday supplement use, though, the real comparison is between oral formats, and that's where bioavailability, how readily an ingredient is made available to the body, comes up
Existing strategies for intracellular protein delivery, such as cell-penetrating peptide (CPP)-based approaches, including the transactivator of transcription (TAT) peptide, have shown promising results but also present limitations, particularly due to the need for recombinant protein manufacturing and daily invasive administration
Therefore, researchers across the world felt the need to understand how antioxidant enzymes, including seleno-GPxs, being the primary ROS detoxification machinery, modulate cellular radiosensitivity
