Which finding from the four-week SBR study on healthy males suggests good short-term safety?

Liver function markers (AST and ALT) showed no concerning changes

In a structured, short-term clinical regimen involving standardized Spanish Black Radish (SBR) supplements taken by healthy male subjects over four weeks, objective safety measures were monitored closely. A key indicator of immediate systemic toxicity risk involves liver function enzymes. The study reported that standard clinical safety measures remained within acceptable laboratory ranges. Specifically, critical liver function markers such as AST and ALT displayed no alarming shifts. Furthermore, while there was a noted drop in GGT, this reduction was deemed clinically acceptable, collectively suggesting that the supplement, when used as directed over a short duration, did not introduce immediate toxicity risks to the liver in healthy adults.
