Brandon and Keith Marz present Marz Sprays Vitamin Oral Sprays to the Sharks in Shark Tank Season 4 Episode 5. The father and son team developed the line of products for people who want to take vitamins and supplements without swallowing pills. Because the vitamins are delivered in a liquid, spray form, the body absorbs them faster.

Marz sells a vitamin C spray, a sleep aid spray, an energy spray, a kids vitamin spray, and a weight loss spray. All products are patented (or patent pending) and trademarked. Brandon and Keith conducted independent clinical studies on the sprays, too. They claim to have over $1 million pending purchase orders and a potential licensing deal with Nature Made.

Marz Sprays Shark Tank Recap

Brandon and Keith enter seeking $200,000 for 10% of their business.

Did Marz Sprays Get a Deal on Shark Tank?

Mark thinks Marz is a scam, and even when Keith tells him they have the ‘first mover’ advantage, Mark goes out. Daymond thinks it will be too difficult to clear the sprays for sale in foreign countries, so he’s out. Robert isn’t a supplement person, so he’s out too.

Lori likes the products and offers $200k for 30%, contingent on a deal with Nature Made. Kevin offers to partner with Lori, but she doesn’t want to; Kevin offers $200K for 25%, and Lori matches the offer.

Brandon and Keith confer and counter Lori with $200K for 25% with a “redemption option.”  They say they’ll accept her offer if she gives them an option to redeem half her stock at four times the purchase price. Lori agrees, and she partners with Brandon and Keith.

Marz Sprays Shark Tank Update

The deal with Lori ultimately never closed. Marz has expanded its distribution internationally by selling directly to consumers online, through retailers and distributors, and through TV commercials. They are still exploring private label opportunities in the US and abroad. Marz began rolling out to big-box retailers in the first and second quarters of 2013. After their appearance on Shark Tank, sales have increased to over $1 million.

Update Segment

The business gets an update segment in Shark Tank Season 5 Episode 26. They’ll reveal nationwide distribution in Walgreens and Hudson News, plus give an update on international sales.

In 2014, they shipped $100,000 worth of product to Walgreens, but the company refused to pay. They were forced to sue and prevailed. The product eventually got on the shelves at Walmart. The company also redesigned its packaging. By 2020, it had products in over 20,000 stores.

The company didn’t have the meteoric growth originally projected, but as of January 2023, it had annual revenue of $4 million. In a June 2024 check-in, the company website was down, and social media had not been updated since 2021.

Brandon’s LinkedIn page lists the company as still “open,” but he’s now the Chief Strategy Officer at LifeRoc Capital, LLC, a business he co-founded in 2017. Keith Marz is keeping a very low profile.

Considering the company’s growth, setbacks, legal wins, etc, the estimated net worth of Marz Sparys is between $1.8 million and $4 million.
