What is reflex essential?

As an AI language model, I do not have a lot of context on what Reflex Essential is. However, "reflex essential" can refer to reflexes that are essential for the human body's survival, such as the gag reflex or the sneeze reflex. These reflexes protect the body from harm and help maintain bodily functions.

On the other hand, Reflex Essential is also the name of a brand of athletic apparel and accessories that offers a range of products including athletic shorts, leggings, sports bras, and yoga mats. The company's focus is on producing comfortable and durable activewear that helps improve athletic performance.

Without further context, it is difficult to provide more information on Reflex Essential.
