ClearDrops® is the FIRST DIETARY SUPPLEMENT IN THE WORLD that can support the claim of crossing cellular membrane with the first invitro pharmacokinetic study conducted, EVER, for a dietary supplement.

ClearDrops® can support this claim because the same study that is required for every drug available in a pharmacy was, also, done on ClearDrops® to prove how it performs in the body.


Peer review has become the foundation of the scholarly publication system because it effectively subjects an author’s work to the scrutiny of other experts in the field. Thus, it encourages authors to strive to produce high quality research that will advance the field.

Peer review also supports and maintains integrity and authenticity in the advancement of science.

A scientific hypothesis or statement is generally not accepted by the academic community unless it has been published in a peer-reviewed journal.

The Institute for Scientific Information (ISI) only considers journals that are peer-reviewed as candidates to receive Impact Factors.

Peer review is a well-established process which has been a formal part of scientific communication for over 300 years.
