Procter & Gamble is one of the biggest names in consumer products.
"We are really happy with the asset itself," he told CNBC's Sara Eisen on "Squawk on the Street." "It's a really well-run operation, and it's been around for a long time."
The deal is meant to expand P&G's health and wellness business. That unit already sells Metamucil, Align Probiotic and New Chapter vitamins, plus Oral-B and Vicks.
Vitamins are not a new category for P&G. The company's goal is to own premium, relevant brands that younger shoppers care about.
Thorne has been around for decades.

Thorne's CEO, Colin Watts, said earlier this year that the brand could eventually reach billion-dollar annual sales. The customer base skews young, with customers under 40 accounting for most of its revenue, and more sales are now coming straight to consumers online.
That online shift matters. It means Thorne has a direct relationship with the people buying its products, which is something big consumer companies love.
Supplements have been gaining popularity as people reach for vitamins to help with sleep and energy. Health and Human Services Secretary Robert F. Kennedy Jr. has pushed supplements through his "Make America Healthy Again" movement and has described his own daily regimen as so extensive that he can't name all of the vitamins he takes.
P&G is the latest big consumer company to buy a trendy supplement brand. Consumer goods giant Unilever bought gummy supplement brand Grüns earlier this year.
Buying an existing brand is one way for a big company to get a built-in customer base. That is the pattern behind both the P&G and Unilever deals.
Thorne will be a small part of P&G's overall business.
That goal makes sense after a soft recent quarter. P&G sold about the same amount of products as a year earlier, revenue came in below expectations, and the healthcare segment was the weakest in terms of volume.
A brand that is already growing and already popular with customers under 40 offers a way to fix that.
You might not know Thorne by name, and that is fine. The bigger story is that major consumer companies are treating supplements as a serious growth market.
That does not mean every vitamin brand will turn into a winner. But when a company like P&G decides to buy a brand that younger customers are already buying, it is a sign that the supplement boom has staying power.
That single deal will not change your portfolio overnight. The bigger story for your portfolio is the direction: the companies that own your everyday brands are treating vitamins and supplements as a long-term habit, not a passing trend.
