Tati Westbrook Launches Unfair Advantage

Tati Westbrook is officially back in brand-founder mode — but don’t expect the long-awaited next chapter of Tati Beauty. The beauty YouTuber has actually returned to the wellness space with Unfair Advantage.

Here’s everything you need to know.

What Is Unfair Advantage?

Unfair Advantage is a new functional beverage brand built around clean energy, with gut support and beauty-adjacent benefits thrown in for good measure.

Meet Go Go Juice — The First Unfair Advantage Drop

The brand’s first product is Go Go Juice, a Sour Raspberry-flavoured powdered energy drink designed to be mixed with water and taken whenever you need a boost, whether that’s in the morning, before a workout, or during that 3pm slump when coffee calls. It costs $49.95 for a pack of 20.

Clean Energy & Gut Health: Inside Go Go Juice

Go Go Juice is packed with 75mg of natural caffeine from guarana seed extract, plus a mix of prebiotics, phytonutrients, methylated vitamin B12, vitamin C, and ionic trace minerals. It’s pitched as a cleaner alternative to standard energy drinks, cutting out all the usual suspects: added sugar, stevia, sucralose, artificial sweeteners, fake colours, preservatives, and fillers. It also checks pretty much every dietary box — it’s gluten-free, vegan, keto-friendly, and low-glycemic.

This isn’t just about dumping caffeine into your system, though. We’re talking about steady, sustainable energy without the heart-racing jitters or that brutal afternoon crash. The brand is banking on the combo of natural guarana seed extract and methylated vitamin B12 to make that happen.

Then there’s the gut-health angle. Each serving delivers 3g of prebiotic fibre, sourced from a blend of chicory root, Jerusalem artichoke, non-GMO corn, and agave, to help keep your digestion on track and support a healthy microbiome.

So, Where Does Beauty Come In?

While this is not a beauty product in the traditional sense, Unfair Advantage does make skin-supporting claims, saying Go Go Juice includes vitamin C and phytonutrients to help support collagen and a healthy-looking glow. It’s not quite a serum-in-a-sachet situation, but it does sit firmly within the growing beauty-from-within category of ingestible wellness.

Why This Isn’t Tati Beauty 2.0

Westbrook’s latest venture comes after a complicated few years in beauty, from the launch of Halo Beauty to the highly successful Tati Beauty, and the very public controversies that followed.

In 2021, she announced the closure of Tati Beauty after just two years, citing a number of factors, including the impact of COVID-19 and the then-ongoing lawsuit involving Halo Beauty. In 2024, it was reported that she had settled the four-year legal battle, left Halo Beauty, and was planning to relaunch a beauty brand.

However, Westbrook recently revealed during a YouTube live that, due to a settlement agreement with her former business partner, she could no longer launch colour cosmetics unless she paid $9 million for the privilege.
