What kind of pill is this white caplet with no score line with qs imprint on both sides?

The white caplet with "QS" imprinted on both sides is likely a dietary supplement or over-the-counter medication, as it does not correspond to any well-known prescription medication. It's important to verify its identity through a reliable source, such as a pharmacist or a drug identification app, since imprints can vary by manufacturer. Always exercise caution and consult a healthcare professional if you're unsure about any pill's purpose or safety.
