I believe these products are based on pseudoscience, here's my reasoning: These products hold scientific inconsistencies, this company appears to use questionable advertising methods like what seems to be paid actors, automated bots on social media, they promote a plethora of conspiracy theories. Dr. Ryan Shelton is an Alternative Medicine Practitioner, or as he labels himself a "Naturopathic Doctor" which is not a real licensed medical doctor but rather a non-scientific practice that holds controversy especially for people who suffer from muffled hearing, tinnitus, and noise-induced pain/discomfort such as myself and would like to see real science based medicine address these issues. Zenith Labs, the sister organization of the now semi defunct SparkHealthMedia, is an alternative medicine company owned by Daniel Toh, located in Auckland, New Zealand, however its mascot and only public representative is "Doctor" Ryan Shelton. Mr. Shelton sells consumable all-natural supplements claiming to treat various medical conditions "nature's way", some of these conditions cannot be appropriately addressed by conventional modern science and alternative non-science based medical practitioners like Ryan Shelton believe they have answers where science doesn't, such as addressing "hearing loss, tinnitus, and whatever poor definition of the word "hyperacusis" is, as well as other conditions claiming nature has all the answers.

They don't rely on paid actors or online marketing gimmicks, they don't have to do any of that when they use real scientific methods.
