Many drugs look promising in cells, mice, or tissue samples but fail in later stages because: The treatment doesnt work well enough in humans It causes side effects at real doses The effect fades over time The human joint environment is much more complex than the lab So while we are hopeful, there is a long road ahead before this approach could become a real treatment
Results showed a drop in average homocysteine blood serum levels in the vitamin group, which may be indicative of an improvement in nervous system health
Your skin is worth that kind of attention
The more plausible worry is indirect: if oral glutathione alters the gastric micro-environment (for instance, by binding trace minerals in the gut lumen), it could marginally shift the pool of free cations available to complex with alendronate, making absorption even less predictable
Simultaneously, hydrogen selenide (H 2 Se) generated from the metabolism of dietary selenium species is converted into selenophosphate (H 2 SePO 3 ) by the enzyme selenophosphate synthetase 2 (SEPHS2) which is then used as a substrate by the enzyme O-phosphoseryl-tRNA [Ser]Sec selenium transferase to incorporate selenium into phosphoseryl-tRNA [Ser]Sec to form Sec-tRNA [ser]sec
