Stevia has extensive safety data and regulatory approval from FDA, EFSA, and others. Good evidence supports its non-caloric sweetening properties and glucose neutrality in typical use. Limited clinical evidence for specific health benefits beyond sweetening; most health claims remain preliminary.
Grade B: Some human trials support key claims; further confirmation needed.
