The goal of this clinical trial is to investigate the efficacy and safety of Lipase Thera-blend and Lipase Thera-blend + tributyrin on memory in healthy adults with self-reported memory problems. The main question[s] it aims to answer [is/are]:

Does of Lipase Thera-blend improve memory in healthy adults? Does Lipase Thera-blend + tributyrin improve memory in healthy adults?

Researchers will compare Lipase Thera-blend and Lipase Thera-blend + tributyrin against a placebo to see if the investigational products improve memory parameters.

Participants will be asked to consume either placebo, Lipase Thera-blend, or Lipase Thera-blend + tributyrin and asked to complete memory questionnaires to assess memory.
