UFC flyweight contender Maycee Barber finds herself at the center of a perplexing medical mystery while simultaneously promoting a controversial health product.
Barber, currently ranked fourth in the 125-pound division, has been grappling with an undiagnosed illness for several months. The 26-year-old star, known as “The Future,” has consulted over 15 different medical professionals in her quest for answers, but to no avail.
“The last several months have been some of the most mentally challenging, frustrating, and discouraging times that I have experienced,” Barber shared on Instagram. She described the emotional toll of her condition, expressing her struggle to maintain hope and patience during this difficult period.

The timing of Barber’s health issues is particularly unfortunate, as she was riding a six-fight winning streak and appeared to be on the cusp of a title shot. Her withdrawal from a high-profile bout against Rose Namajunas at UFC Denver has left fans and fellow fighters concerned about her well-being.
In an intriguing twist, amidst her health struggles, Barber has become involved in promoting a controversial product. She recently received approximately $50,000 worth of shares from American Aires Inc., a company specializing in electromagnetic radiation protection devices.
The product in question is the Lifetune Mini, a pendant-like device priced at around $240 that claims to shield wearers from the potentially harmful effects of WiFi signals and other electromagnetic radiation. Barber was seen wearing the pendant during UFC 299 weigh-ins and has made several social media posts about it.
This endorsement has raised eyebrows in the scientific community, as the claims made by American Aires Inc. lack empirical evidence and have been dismissed by experts as pseudoscientific. The company’s website describes their technology using vague, scientific-sounding terms, including a patented “Method for Protecting Biological Objects from the Negative Influence of Technogenic Electromagnetic Radiation.”
Despite the controversy surrounding their products, American Aires Inc. reported a 45% year-over-year increase in sales, reaching $2.8 million in the second quarter of 2024. However, the company still posted a loss of $300,000 due to extensive marketing expenditures.
Barber’s involvement with American Aires Inc. is part of a broader marketing strategy by the company, which has secured endorsements from other high-profile athletes and celebrities. Their #AiresAthletes campaign features NFL legend Tiki Barber, Toronto Maple Leafs’ John Tavares, and Toronto Raptors’ RJ Barrett, among others.
As Barber continues to search for answers regarding her health, her promotion of the Lifetune Mini has added an unexpected layer to her story. Fans and observers are left to wonder about the connection, if any, between her mysterious illness and her endorsement of this controversial product.
For now, Barber remains focused on her recovery and eventual return to the Octagon. “I definitely didn’t see the path to being a champion looking like this,” she admitted, “but nonetheless I will continue to push forward and I WILL BE THE FLYWEIGHT CHAMPION. It’s on God’s time not mine.”
